The Science of Skin of Color

The science of skin of color focuses on understanding the morphological, physicochemical, and clinical characteristics of skin in individuals with varying levels of pigmentation It is especially important in dermatology and in the development of personal care products when diagnosing and treating individuals with darker skin tones. Historically, more research has been conducted on lighter skin types, which has led to gaps in the knowledge base of our scientific understanding for skin types containing higher levels of melanin In this article, we highlight distinct characteristics of melanated skin and address differences as compared to non-melanated skin

n Geographic-Ethnic Origins of Skin of Color

Skin of color refers to a broad range of people coming from various ethnic and racial groups including African, Hispanic/Latino, Asian, Middle Eastern and North African, Indigenous Peoples, Pacific Islanders, and Multiracial Individuals 1 African descent refers to individuals often categorized as Africans, African Americans, and Afro-Caribbeans. Hispanic/Latino usually refers to someone from a Latin American country who is Indigenous, Mestizo (multi-racial), or Afro-Latino. People of Asian descent include East Asians (e.g., China or Japan), Southeast Asians (Philippines, Thailand, V ietnam, etc ), and South Asians (India, Pakistan, Sri Lanka, Bangladesh) Indigenous Peoples refers to Native Americans, Indigenous Australians, Alaskan Natives, and other indigenous groups Some researchers suggest not using the ter ms ethnic, Hispanic, or Asian to describe skin of color since they refer to non-specific groups of people.2

n Classification of Skin Tone

Typically, skin tone is categorized by the Fitzpatrick skin type scale according to its color and response to UV radiation (see Table 1). It should be noted that the Fitzpatrick scale broadly classifies Type V and VI skin and should be updated and expanded to better represent darker skin tones 3, 4 The reader should keep in mind that other scales, based on instrumental measurements, have also been proposed as a means to characterize skin color type.5

Table 1. Fitzpatrick Skin Classification System

Skin Type Skin Color

I Very fair, pale white skin

II Fair skin

III Medium or olive skin

IV Olive or light brown skin

V Brown or dark brown skin

VI Dark brown or black skin

Letter from the Chair …Amber

In a New York minute it will be fall, and what a hot summer it has been for NYSCC. Following our very successful Sunscreen For mulations Symposium in May, I had the honor of representing the NYSCC as a presenter at Spelman College’s inaugural Black Beauty STEMinist Lab

Intensive and Symposia This weeklong event hosted students from 15 colleges and universities to provide hands-on laboratory experience in beauty for mulation and exposure on a wide range of topics while celebrating the contributions of Black women in cosmetic science

We also ended June with a well-received webinar on diverse beauty rituals, with each speaker talking about the unique ingredients from their part of the world and culture.

Our summer activities offered great opportunities for networking and fun Many foursomes enjoyed a wonderful day at the beautiful Crystal Springs Golf Course in Hamburg, New Jersey for our annual Golf Outing in July, and the nine students of the NYSCC Inter nship Program were introduced to the Chapter Hurricane Debby blew through just in time to spare our Fishing Trip and first ever Seafood Boil on August 10th. It was a gorgeous day on the water as attendees fished and ended the day with delicious crab legs and shrimp

Looking ahead, there are some exciting educational programs planned in the next three months:

• September 10th: Skin Care Inclusivity: Caring for Melanated Skin Symposium

• October 15th: Emerging Trends in Oral Health and Beauty

• November 7th: Pet Care and Grooming

• November 14th: Hear from the CEW Supplier’s Award Judges on this Year’s Top Ingredients & For mulations

This month we also have our Culinary Event on September 18th at the Midtown Loft and Terrace This popular event promises to diversify your palette Sign up soon! This event will sell out very quickly.

The NYSCC continues its collaboration and support of “sister” chapters with board members and Suppliers’ Day team members at the SWSCC Suppliers’ Day in Irving, Texas, IFSCC Congress in Brazil, Naturally Kiawah Symposium in Kiawah Island (South Carolina), and National’s Scientific Meeting and Showcase in Los Angeles

Check out all the programs the NYSCC will be supporting this fall in our promotion on page 4 We strive to offer the very best to our members and the cosmetic chemistry community on a global scale We certainly have you covered!

It has been an honor to serve on the CEW Beauty Awards Nominating Committee and I can’t wait to see who will be revealed as finalists at their Beauty Expo on September 18th. The NYSCC will be there as well to showcase the eight finalists of the Supplier’s Award for Ingredients and For mulation

Our special events team is deep in planning mode for our 70th Anniversary Gala and Education Night event Taking place on November 16th at the iconic Plaza Hotel, this will truly be a night to remember as we celebrate our past and all that we have achieved as a Chapter and look to the future of cosmetic science. We will also be announcing the recipients of the Scholarship and Grant Awards, Chapter Merit Awards, and new special prizes

Lastly, it is election time and ballots will be going out soon for our 2025 Board of Directors Please be on the lookout and cast your vote

W ith a wide range of educational programming and activities planned for the final months of the year, I look forward to seeing you at an upcoming NYSCC event

The Science of Skin of Color

n Skin Pigmentation

Melanin is the major pigment in skin and is produced by melanocytes dendritic cells located in the stratum basal layer of the viable epider mis Melanin is further classified as eumelanin (brown and black pigment) and pheomelanin (red and yellow pigment). As would be expected, higher levels of eumelanin in skin lead to darker skin tones Greater amounts of pheomelanin are found in individuals with very fair (Type I) skin.

Figure 1: Structure of a melanocyte RER = rough endoplasmic reticulum; SER = soft endoplasmic reticulum

Eumelanin and pheomelanin are produced from the amino acid tyrosine through a series of reactions with two crucial steps at the beginning of the biosynthesis pathway catalyzed by the enzyme tyrosinase In the first step, tyrosine is converted to dihydroxyphenylalanine (DOPA) followed by an oxidation reaction resulting in the for mation of dopaquinone In the third step of the reaction, dopaquinone can follow one of two possible pathways it can continue with the melanin synthesis pathway or react with cysteine leading to the production of pheomelanin

Molecules of melanin are packaged into melanosomes small organelles that are deposited by melanocytes into neighboring keratinocyte cells for ming a microparasol above the cell nuclei The epidermal melanin unit relies on proper communication between melanocytes and epidermal keratinocytes to ensure proper physiological function of the skin. The distribution and size of melanosomes are important for deter mining skin color Typically, in darker skin the melanosomes are larger and more dispersed 6 The function of melanin, especially eumelanin, is to absorb incoming UV and visible light thereby protecting the DNA in replicating keratinocytes of the stratum basal layer 7 On the other hand, pheomelanin can acts as a photosensitizer, causing damaging free radical reactions to occur in skin when exposed to solar radiation.8

In addition to eumelanin and pheomelanin, there are many other chromophores in the skin These include nucleotides from DNA and RNA, amino acids (tryptophan, tyrosine, phenylalanine, and cysteine), lipofuscins, beta-carotene, hemoglobin, NADH, NADPH, flavins, 7-dihydrocholesterol, and trans-urocanic acid While most of these molecules primarily absorb UV radiation, some of them also have significant absorption profiles in the visible region of the electromagnetic spectrum Beta-carotene, hemoglobin, and lipofuscins influence the color and appearance of lighter and darker skin

Melanin (a mixture of eumelanin and pheomelanin) has strong absorbance in the UV region of the electromagnetic spectrum which decreases monotonically into the visible region of the spectrum It is important to note that UVB (280 – 320 nm) and UVA (320 – 400 nm) light are responsible for damage to DNA in skin cells, which could ultimately lead to carcinomas Therefore, a greater degree of protection from UV damage is provided in skin with greater amounts of melanin UVB damage to nucleotide bases predominantly involves the for mation of cyclobutane pyrimidine dimers as well as other cross-linked structures (pyrimidine-pyrimidone (6–4) photoproducts) of double helical DNA strands DNA damage by UVA light involves free radicals that are for med due to solar exposure. In summary, melanin absorbs UV light reducing the amount of light available to cause DNA mutations

Melanin also offers protection against photoaging It has free radical scavenging activity, allowing it to neutralize free radicals, thereby averting (or reducing) oxidative processes har mful to the skin In addition, melanin absorbs UVA light, preventing it from penetrating deep into the der mis and damaging elastin and collagen, which are essential for maintaining skin fir mness and elasticity. Further more, melanin

plays a role in modulating inflammation in sun-exposed skin. Chronic inflammation can be detrimental to skin homeostasis

While melanin does provide skin of color greater protection, individuals with darker skin still need to use sunscreen to protect the skin from photoaging, hyperpigmentation, and skin cancer.

n Biophysical Characteristics of the Epider mis

The amount of melanin in darker, as compared to lighter skin, is the most striking distinction between different skin types However, there are other facets of skin structure that are unique in darker skin For example, the stratum cor neum in darker skin is more compact (ca 20 vs 16 cell layers) than white skin, although its thickness is comparable.9 In addition, sebum production was reported as greater in African American skin than Caucasian skin 10 La Ruche and Cearini reported that the electrical resistance of black skin is greater than white skin, which could explain why black epider mis is less hydrated than white epider mis 11 Studies have even shown that there are differences in skin of color and light skinned subjects in ter ms of lipid levels, transepider mal water loss (TEWL), pH, and mast cell granule size However, some of these studies present conflicting data and have a limited pool of subjects.12 Overall, there is a pressing need to conduct more studies to better elucidate differences and similarities among various ethnic/racial groups. Recently, Salminen and coworkers published a study highlighting the use of reconstructed tissues with various degrees of pigmentation to investigate human skin barrier function and penetration of cosmetic and phar maceutical ingredients as a preclinical tool for different skin types 13

n Common Der matological Conditions in Skin of Color

There are several different conditions where individuals with skin of color are more adversely affected than their counterparts with lighter skin In general, melanated skin is more adversely affected by a number of common skin conditions. In the sections below, we highlight several skin ailments that disproportionally affect individuals with skin of color, which includes hyperpigmentation, depigmentation, acne vulgaris, keloids, and dry skin conditions 14, 15

Diagnosis of certain skin diseases can be a challenge in skin of color patients.16, 17 Some skin conditions may appear differently in darker skin, leading to misdiagnosis or delayed diagnosis 18 In addition, treatment protocols can be unique for each skin tone. For instance, laser treatments must be carefully chosen to avoid adverse effects on melanin-rich skin Finally, it is important to understand the cultural perceptions of skin conditions and to be aware of the psychological impact on the patient.

• HYPERPIGMENTATION

Post-inflammatory hyperpigmentation (PIH), melasma, and lentigines are the most common hyperpigmentation conditions in skin of color (e.g., skin Type V and VI) and tend to be more pronounced than in lighter skin tones Protease activator receptor-2 is thought to play an integral role in the development of hyperpigmentation It is a membrane-bound protein expressed in keratinocytes, which is involved in the transfer of melanosomes from melanocytes to keratinocytes.19, 20

PIH is a darkening or discoloration of the skin that appears after a wound has healed Several conditions can cause PIH including acne vulgaris, eczema, psoriasis, or trauma (cuts, bur ns, etc.). Treatment options for PIH consist of sun protection, topical treatments (hydroquinone, retinoids, (continued on Page 8)

vitamin C), chemical peels, and laser therapy 21-24 However, it should be pointed out that a comprehensive review of 41 studies representing 877 patients demonstrated that the current treatment protocols (e g , topical treatment, laser therapy, etc.) for PIH do not satisfactorily result in a complete response from the patient 25

Melasma is a condition characterized by discolored patches on the skin (usually brown or gray, brown) caused by exposure to UV radiation, hormonal changes, and genetic predisposition It most often appears in areas that are exposed to the sun Melasma is usually treated by exercising skin photoprotection (clothing, sunscreen, etc.), employing topical treatments (hydroquinone, tretinoin, corticosteroids, etc.), and carrying out der matological procedures (chemical peels, microder mabrasion, or laser therapy) Lentigines are often referred to as liver spots or age spots. They are darkened patches (typically brown or black) on the skin that are nor mally found in areas of the skin exposed to the sun In most cases, they are associated with photoaging or chronological aging Wearing sun protection can help prevent the for mation of lentigines Treatment options consist of topical treatments, cryotherapy, chemical peels, and laser therapy

• DEPIGMENTATION

Conditions such as vitiligo can be more noticeable and psychologically impactful in individuals with darker skin V itiligo results in the for mation of white patches on the skin due to the destruction of melanocytes in these regions of the skin. While the cause and associated mechanisms of vitiligo are not fully understood, it is known to be an autoimmune disorder where melanocytes are attacked by the immune system thereby preventing pigmentation from being produced. Currently, there is no cure for vitiligo However, some treatment options to help alleviate the discoloration of the skin include treatment with topical steroids, phototherapy, and skin grafting In recent years, attention has focused on melanocyte stem cell mobilization as another possibility to use in the treatment of vitiligo 26

ACNE VULGARIS

Acne vulgaris occurs when the pilosebaceous unit becomes obstructed with sebum and differentiated keratinocytes due to hyperkeratinization and excessive oil production, resulting in the for mation of comedones (obstruction of the pores that appear as small bumps on the surface of the skin) Comedones can be open (black heads) or closed (white heads), which are both non-inflammatory for ms of acne. On the other hand, if the comedones become infected by bacteria, they can develop inflammatory lesions such as papules, pustules, nodules, and cysts. Hypercolonization of the pilosebaceous duct by the bacterium Cutibacterium acnes (for merly Propionibacterium acnes) has traditionally been considered as mostly responsible for the ensuing bacterial infection

In the case of darker skin tone individuals affected by acne vulgaris, there can be significantly more scarring and hyperpigmentation The for mation of inflammatory lesions is more common in skin of color individuals. PIH occurs after the acne wound has healed resulting in the overproduction of melanin (hyper melanonsis) In a comparative study, PIH due to acne was shown to be more prevalent in African American (65%) and Hispanic (48%) women than in Asian (18%), Caucasian (25%), and Continental Indian (10%) women 27

Figure 3: Molecular structure of a repeating portion of pheomelanin, which contains benzothiazine units

Treating skin of color for acne vulgaris can be challenging for der matologists Special care should be taken to ensure that treatment is mild since darker toned skin is more susceptible to PIH. For example,

topical treatments such as benzoyl peroxide, retinoids, and azelaic acid can be used, but lower concentrations should be employed Oral medications for acne treatment consist of antibiotics, contraceptives, and spironolactone Oral contraceptives and spironolactone are hor monal modulating treatments and can help reduce the risk for PIH. Care should also be taken when treating melanated skin with lasers or chemicals, again to avoid hyperpigmentation

KELOIDS

People with darker skin are more prone to developing keloids and hypertrophic scars A keloid is an overgrowth of scar tissue Essentially, it is for med due to the overproduction of collagen and the extracellular matrix during the healing process. Once for med, keloids can continue to grow and become much larger in size While keloids are not necessarily har mful, patients find them irritating due to itchiness (pruritis) and pain. Equally important, there is a significant psychosocial impact experienced by patients with keloids

Individuals with darker toned skin are markedly more susceptible to developing keloids Some of the current treatment options for keloids consist of corticosteroid injections, surgical excision, radiation therapy, laser therapy, silicone gel dressings, and cryotherapy One of the greatest challenges in the treatment of keloids is their tendency to recur. Looking towards future, there is a lot of activity reported in the der matological literature by research groups attempting to discover novel treatments for keloids 28

DRY SKIN CONDITIONS

There are certain dry skin ailments that individuals with melanated skin are more prone to develop or have unique presentation of the condition than the lighter skin population. For example, xerosis is a common condition that results in ashy patches on the skin, which are especially notable in populations of African descent Atopic der matitis (eczema) is generally more severe in darker skin toned subjects 29 Patients with a family history of eczema or other atopic diseases (asthma and hay fever) are more susceptible to suffering from atopic der matitis Another interesting point to note is that eczema appears differently in individuals with darker skin tones. For example, in lighter skin toned subjects, eczema can be clearly identified by the degree of redness In darker skin types, eczema may appear brown, purple, or even gray. Papular eczema is another condition that predominantly affects dark toned skin and manifests itself as small itchy bumps on the skin surface

n Photoprotection for Skin of Color

Typical measures for photoprotection consist of avoiding direct sunlight, wearing sun-protective clothing, using sunscreens, and minimizing exposure to the mid-day sun 30 One of the challenges with sunscreen use in skin of color individuals is the cosmetic appearance of inorganic sunscreens, which have become more important since recent FDA legislation categorized chemical sunscreens as NOT generally regarded as safe and effective (GRASE) 31

In light skinned individuals there is a plethora of knowledge and awareness about photoprotective measures However, in skin of color populations it is often incorrectly assumed that there are minimal health risks associated with exposure to solar radiation 32 In fact, skin of color populations can suffer from pigmentary disorders, photoaging, and skin cancer (basal cell carcinoma, squamous cell carcinoma, and melanoma)

While the development of skin cancer is less prevalent in skin of color subjects, melanoma has a greater degree of morbidity and mortality in this population.33 This is believed to occur because of late detection in skin of color patients possibly due to differences (as compared to light skinned subjects) in the anatomic locations and der matoscopic patter ns of pigmentary manifestations of disease, which makes it difficult to differentiate between physiologic and pathologic pigmentation patter ns 34

(continued on Page 10)

n Investigating Mechanisms of Pigment Modulating Active Ingredients

The biosynthesis of melanin is regulated by alpha-melanocortin (alpha-MSH) a peptide hor mone that binds to melanocortin 1 receptors (MC1R) on melanocytes Alpha-MSH also plays an important immunomodulatory role by reducing inflammation. It is an inhibitor of pro-inflammatory cytokines and promoter of anti-inflammatory cytokines This is especially important in inflammatory skin conditions, such as atopic der matitis and psoriasis. Mutations and variations in the MC1R gene affect the signaling ability of alpha-MSH and are ultimately responsible for the development of different pigmentation phenotypes, such as fair skin

Considerable efforts have been made to develop agonists (active ingredients), which stimulate pigment production in skin Such research is carried out with the aim to develop ways to increase skin pigmentation, thereby reducing the harmful effects of solar radiation on the skin. In addition, development of such actives provides us with the potential to treat vitiligo and other photosensitivity conditions

Typically, melanin modulating active ingredients are tested in the laboratory using a single type of pigmented reconstructed skin model or melanocyte line 35 Alter natively, one may use several skin model phototypes or melanocyte strains with varying degrees of pigmentation 35, 36 For example, Jackson and coworkers developed a pentapeptide, which mimics alpha-MSH, using two skin model phototypes to test its efficacy 36 This ingredient, now marketed in Europe as a self-tanning agent, has the INCI name: Benzoyl Dipeptide-18 D-Phenylalanyl Arginyl D-Tryptophan Dipropylamide Mesylate. In summary, researchers carrying out preclinical studies should consider using test systems with various degrees of pigmentation, in a similar manner to how a pigmentation clinical study would be designed

n Concluding Remarks

Skin of color populations are an important worldwide demographic that have unique der matological treatment and skin care needs. Most of our infor mation and understanding about the biological and physicochemical behavior of skin comes from a vast amount of research in the published literature primarily focused on light skinned subjects. The manifestation, diagnosis, and treatment of various conditions in skin of color individuals should be at the forefront of der matological and cosmetic science

NYSCC Chapter Special Events

Since the beginning, special events have been part of the NYSCC calendar. “Ladies’ Night” is the earliest The following text is from 1956: “Ladies Night on April 25th featured Dr Er nest Guenther of Fritzsche Brothers, Inc. Dr. Guenther showed one of his latest movies along with colored slides of a trip around the world ” Er nest Guenther was a highly respected scientist He wrote a classic six volume work on essential oils, which was completed in 1952 and is still a standard work on the subject In the Summer 1975 NYSCC newsletter (the name Cosmetiscope was still in the future), we find “Our Special Events program this year includes three different activities: Pocono’s Weekend, Theatre Night, and Camping Trip.” A Special Events Committee was created but was abolished in 1977 due to lack of interest The most infamous special event in NYSCC history was the boat trip of 1979 (discussed in the February 2023 issue of Cosmetiscope) a success in ter ms of attendance but a financial disaster leading to the creation of Suppliers’ Day

In 1984 a social weekend was held at the Americana Great Gorge Resort with a technical paper presented on Saturday mor ning on the topic of hair care A number of years later, a December dinner dance was held in 1990 The NYSCC special events now are the Ski Trip (in conjunction with the Long Island Chapter), Fishing Trip, Golf Outing, and Culinary Event Some years in the past the golf outing included a separate tennis component. The earliest documented years of the current special events are: Ski Trip (1996 or earlier), Golf Outing (1996), Fishing Trip (1996), and Culinary Event (2008)

Cosmetic Procedures in People of Color

Oma Agbai, M.D., FAAD (University of Califor nia – Davis)

The intersection of aging occurring in a large segment of the U.S. population, increased life expectancy, a focus on appearance, and readily available and accessible cosmetic procedures have served to drive an increase in the number of non-surgical cosmetic procedures perfor med in the last 20 years. Demographic shifts in the U.S. with increases in diverse populations who seek nonsurgical cosmetic procedures infor ms the need for a better understanding of cultural preferences as well as structural and biological differences in the skin of people of color (POC). Although many advances in the for m of cosmeceuticals, cosmetics, and photoprotection have been made to address the aesthetic needs of and minimize complications in POC, non-surgical cosmetic procedures are required to address common aesthetic concer ns Gaps remain in the education of der matologists regarding appropriate selection and execution of non-surgical cosmetic procedures in POC

Cosmetic procedures can effectively treat cutaneous disorders of dyschromia, scarring, manifestations of photoaging, loose skin, and benign growths that commonly occur in POC The most sought-after aesthetic procedures include chemexfoliation, laser resurfacing, neuromodulators, soft tissue fillers, skin tightening, hair removal, and fat reduction Successful completion of cosmetic procedures includes an accurate assessment of the aesthetic skin of color patient as well as the implementation of safe treatment protocols. As cosmetic procedure advancements propel, der matologists have an obligation to train and research how to best curate treatment modalities to better suit their patients of color. This educational initiative will support a favorable outcome and optimal cosmetic results for patients of color

n Sam Fine

What do superstars Queen Latifah, Vanessa L W illiams, Jennifer Hudson and supermodels Tyra Banks, Iman, and Naomi Campbell all have in common? They’ve relied on the expert hand of makeup artist Sam Fine to look their most glamorous That’s because Fine knows that the key to making up goes beyond painting a pretty face. Long before he became a celebrity makeup artist, the Chicago native paid his dues working behind the makeup counter of department stores, an experience he fondly refers to as “the real school of beauty”. There, he encountered women from all walks of life that wanted one thing to look their absolute best He made it his mission to show them how to accentuate their unique beauty by using colors and shades that would best complement their complexions. But most importantly he helped them eliminate their doubts and apprehension about applying makeup so that they too could achieve dazzling results

Fine’s talent and determination has taken him far from the makeup counter, making him one of today’s most sought-after makeup artists His work has appeared on the covers and pages of Cosmopolitan, Harper’s Bazaar, Essence, Vibe, and Marie Claire and was chosen as the first African American spokesperson for Revlon and Covergirl Cosmetics But it was the experiences from his for mative years selling makeup that inspired him to write his first book, Fine Beauty: Beauty Basics and Beyond for African American Women, a how-to guide highlighting his many accomplishments.

As follow-up to his best-selling book, Fine introduced his first instructional DVD, Fine: The Basics of Beauty. As a continuation of his commitment to educate women of color on the “fine” art of makeup, this step-by-step tutorial features three individual makeovers and addresses a myriad of beauty challenges by focusing on tools, technique, and product selection Sharing his wealth of experience and expertise, Fine enables viewers to fully understand all that goes into creating a flawless, natural-looking face.

Not the Regular Suspects: Pollution and Tobacco Now in the Same Cell with the Sun, All Accused of Ageing-Induced Pigmentation

Sun exposure has been classically considered the main contributory factor to hyper-pigmentation as a hallmark of extrinsic skin ageing Recent studies identified other detrimental exter nal factors such as air pollutants and tobacco that have similar actions to UV exposure and share several common intracellular pathways leading to increased melanin production The complexity of pollutants and tobacco smoke as environmental stress factors requires a thorough understanding of the mechanisms by which they alter melanin’s production through repeated and long-ter m exposure Identifying and deciphering the activity of the molecular factors within melanogenic signaling pathways in response to pollutants and tobacco provide support to the cosmetic industry in launching safe and efficacious

products to counteract their detrimental contribution to skin ageing.

Air pollutants impact skin pigmentation by induction of oxidative stress and upregulation of inflammatory markers and mediate their intracellular actions through modulation of Aryl hydrocarbon Receptors (AhR). Several lines of supportive experimental data point towards the action of tobacco on complex cholinergic and adrenergic signaling pathways that ultimately impact the melanin production in response to accumulated exposure over time. The phenomenal crosstalk between multiple signaling pathways by which sun, pollutants, and tobacco adversely affect skin pigmentation is ultimately possible by the activity of Microphthalmia-Associated Transcription Factor (MITF) a common denominator that facilitates the conversion of stress signals into hyper-pigmentation An analysis of available datasets generated by in vitro, in vivo, and clinical studies will also be presented, with emphasis on a diverse range of New Approach Methodologies (NAMs). NAMs-based study design considerations will be presented in support of their fit-for purpose use to address efficacy testing of ingredients or for mulations with potential to modulate molecular pathways gover ning skin pigmentation. These mechanistic experiments ultimately support the identification of raw ingredients and design of cosmetic products intended to counteract in a targeted manner the contribution of pollutants and tobacco to hyper-pigmentation within the extrinsic skin ageing profile.

Physicochemical Properties of Ethnic Hair

Roger L. McMullen, Ph.D. (Ashland, Inc and Fairleigh Dickinson University) and Timothy Gillece (Ashland, Inc.)

Hair from various ethnicities or racial origins have unique physicochemical properties Interestingly, the amino acid composition is the same for all hair types, which has been reported in repeated amino acid analysis studies Asian hair has the most circular cross section while African hair is the most elliptical African hair has a lower radial swelling rate than Asian and Caucasian hair In ter ms of mechanical (tensile) properties, it is generally found that the break stress and elongation at break is lower in African hair than Asian and Caucasian hair The fracture point of the fiber in African hair during tensile measurements can occur in the twist or homogenous region of the fiber. African hair fibers with a larger diameter tend to have looser curls while fibers with thinner diameter tend to have a tighter curl It has also been shown that the lipid content is greater in African hair than other hair types.

In this presentation, we examine some of the differences in the various properties of hair from different ethnicities and attempt to understand how this influences the overall macroscopic behavior of a hair fiber assembly. We first examine the morphological and ultrafine structural characteristics of African and Caucasian hair We further investigate the lipid characteristics of African and Caucasian hair using FTIR imaging to map the lipid distribution within the cross section of hair. Using dynamic vapor sorption, we observe how the influence of the greater distribution of lipids in African hair might lend to its water management properties Finally, we take a profound look at the surface and inter nal structure of African hair using advanced SEM techniques, examining cross sections of hair and generating three-dimensional images of the fiber

The Dark Side of Skin Lightening:

An International Collaboration and Review of a Public Health Issue Affecting Dermatology

Arianne Shadi Kourosh, M.D., MPH (Harvard University)

Skin lightening (SL) for cosmetic reasons is associated with profound negative impacts on well-being and adverse effects on the skin, resulting in immense challenges for der matologists. Despite current regulations, lightening agents continue to dominate the cosmetic industry This session focuses on the findings of our inter national team of der matologists on the topic of skin lightening as a global public health issue, one of great concer n for health and implications of racism and colorism. Examining the practices of skin lightening in Africa, Asia, the Middle East, and the Americas, we aim to inspire a global discourse on how moder n der matologists and practitioners in various aspects of the skincare industry can work together with scientific evidence and cultural competency to serve and protect patients and consumers of diverse skin types and backgrounds In doing so, we hope to promote healthy skin and inclusive concepts of beauty in our patients and society

Ethnic Differences in Appearance of Facial Ageing

Variation in human skin color is a multifactorial trait with a number of major genetic deter minants, several modifier genes, environmental influences such as UV, inter nal hor monal influences, and other stresses like inflammation and barrier disruption Due to their high skin melanin content, Vitamin D is produced less efficiently in dark than light skinned individuals. Nevertheless, dark skinned individuals are able to use Vitamin D efficiently for storage of calcium which is important for bone strength

The appearance of aging results from the decline in skin elasticity and muscle tone and volume as well as bony shape modifications and subcutaneous fat deposition Higher subcutaneous fat deposition (primarily in overweight individuals) fills up the facial folds and creases resulting in a more youthful appearance. In addition, stronger bone density contributes to less bone resorption with age providing a strong underlying structure to the face

Variation in structural and functional skin characteristics have been linked with ethnic background. Studies show that East Asian and to some extent Caucasian skin is characterized by low maturation and relatively weak skin barrier African American skin is characterized by low ceramide levels and high protein cohesion in the upper most layers of the stratum cor neum. These data can be interpreted in ter ms of the high prevalence of xerosis in black skin and increased skin sensitivity in East Asian skin The lecture will cover ethnic differences in facial ageing.

Beyond Black and White: Insights on the Relationship Between Racial Bias and Skin Tone Bias

Much research demonstrates that darker-skinned people, even within a single racial group, contend with social disadvantages in comparison to their lighter-skinned counterparts. Further more, this pro-light skin-tone bias (or colorism) can influence the experience

(continued on Page 24)

of people across various racial, ethnic, and cultural groups Race and racism are highly politicized, highly salient topics in contemporary discourse Is skin-tone bias also? Given that perceivers often rely on skin tone when assigning a racial category to someone that they encounter, how should skin tone and race be understood in ter ms of their distinct biasing influence? Do they always operate in tandem, or do they sometimes operate independently? Does the reason why perceivers favor lighter skin differ based on the race of the perceptual target? The current talk summarizes social psychological research to offer initial responses to these important questions

Overview of Hyperpigmentation and Treatment Strategies in Personal Care

Oluwaseun, M.S., MBA (YG Laboratories and University of Califor nia –Riverside Extension)

Skin color and melanin characteristics are unique to individuals, influenced by genetic predisposition and exogenous factors such as ultraviolet radiation These variations result from differences in the number and size of melanosomes, where melanin is synthesized through melanogenesis. Disturbances in melanogenesis can lead to pigmentary disorders, causing abnor mal skin pigmentation These disorders, classified as hyperpigmentation or hypopigmentation, may be congenital or acquired, per manent or temporary, and affect the entire body or localized areas

Common pigmentary disorders include melasma and post-inflammatory hyperpigmentation, whose precise causes remain unclear but are linked to genetic factors and UV radiation. These disorders can significantly impact psychosocial well-being and overall quality of life Accurate diagnosis is crucial for appropriate treatment, which aims to manage and prevent these conditions through various pathways in melanogenesis

Current treatments include topical agents and procedural methods, with hydroquinone being the gold standard despite its adverse effects However, changing regulations have led to hydroquinone being available by prescription only, posing challenges for accessible topical treatment options in personal care As a result, alter native topical treatments, such as tranexamic acid, arbutin, and licorice root extract, are being explored for their efficacy Additionally, the importance of ultraviolet protection, especially broadspectrum sunscreens, is emphasized for controlling pigmentary disorders.

Understanding the mechanisms of hyperpigmentation and developing effective treatment strategies are crucial for addressing these concer ns This presentation will explore the pathogenesis, psychosocial impact, and treatment strategies for melasma and post-inflammatory hyperpigmentation, highlighting both current practices and emerging alter natives

Evaluating the Effect of Iron Oxides and Ultramarine Blue on the Cosmetic Elegance, Sun Protective Efficacy, and Stability of Inorganic Sunscreens for Dark Skin

Alayna Bouie, MSPS (The University of Toledo)

The reflective nature of zinc oxide and titanium dioxide in sunscreen creates a displeasing white cast on dark skin, categorized as Fitzpatrick phototype IV to VI, deterring regular sunscreen use in these consumer groups Sunscreen is rarely recommended due to the lack of skin cancer testing and sunscreen use education for these consumers. As a result, the occurrence of melanoma, although uncommon, displays at late stages in communities of color, making it more fatal A solution to mitigate the white cast is tinting sunscreens using iron oxides. Many tinted sunscreens on the market are only available in light to medium shades, so complexion products for dark skin typically also leave a displeasing cast, like sunscreens This is due to excessive amounts of black iron oxide in their for mulas

Our preliminary research indicates that ultramarine blue can relieve this issue, yet there is a concer n that it is not stable in formulations The main goal of this study was to compare iron oxides and ultramarine blue in various inorganic sunscreens to mitigate the white cast, evaluate the sun-protective efficacy, and affir m the color stability of ultramarine blue in emulsions Fourteen darkly tinted sunscreens and four nontinted sunscreens were for mulated by varying the emulsion type and pigment ratio. In vitro protection in the ultraviolet range (290-400 nm) and visible light range (400-700 nm) was tested for all samples The color was tested visually via photographs in an IRB-approved consumer study and

based on consumer feedback and objectively using a spectrophotometer Particle size was analyzed using a light microscope and spreadability with a texture analyzer Product stability was tested at 25 and 45 °C for six months. SPF levels were higher for the tinted sunscreens in comparison to the non-tinted ones and had a lower percentage of transmittance in the visible range All samples remained stable at room temperature during the study. Moreover, particle size did not change dramatically for foundations that remained stable at 25 °C for four months, however, at 45 °C samples destabilized after two weeks The addition of ultramarine blue decreased the gray cast from the high black iron oxide load and remained stable at 25 °C for four months

The Role of Blue Light (High Energy Visible Light) in Hyperpigmentation

Howard Epstein, Ph.D. and My Trinh Luu (EMD Electronics an affiliate of Merck KGaA)

In the past it was believed that visible light had minimal biological impact to skin More recent studies show that visible light has significant impact on various der mal biological processes including hyperpigmentation Publications indicate that visible light, particularly blue light (415 nm), is associated with oxidative stress leading to protein damage, DNA damage, inflammation, and hyperpigmentation, all contributing to aging. Currently opsin-3, a light-sensitive protein was identified in skin and found to be expressed in human epider mal melanocytes, the cells that produce melanin Given that skin overexposure to visible light/high energy visible light promotes production of reactive oxygen species, pro-inflammatory cytokines including MMP-1, and hyperpigmentation, we evaluated the ability of an attenuated titanium sun filter (UV-TiO2), Bis-ethylhexyl hydroxydimethoxy benzylmalonate (HDBM), Indian gooseberry extract (emblica), and ectoin for the ability to mitigate the impact of high energy visible light on human skin explants post irradiation at 400-500 nm Markers for opsin-3, DNA oxidation (8-OHDG), oxidized proteins, and MMP-1 production were evaluated. Our findings show each of the above ingredients can provide broad protection against high energy visible light exposure via multiple molecular pathways

Considering Ethnic Skin Needs to Develop an Inclusive Natural Active Ingredient

Whether masculine, feminine, young, old, or from the four cor ners of the world, all skin has its particularities and concer ns. In this context, SILAB has identified the main cutaneous characteristics of consumers in ter ms of ethnicity, age, and gender Depending on the ethnic group, the major difference comes from skin color in relation to the presence of melanin Lighter skins are characterized by low melanin levels, making them more vulnerable to photoaging and the premature emergence of pigmentation spots They are also more fragile, and generally reflect a premature loss of elastin and collagen fiber structure, leading to the early appearance of pronounced wrinkles. Melanin rich skin better resists the negative side effects of photoaging That said, heterogenous pigmentation can lead to irregular skin tone and these skin types have a very high transepider mal water loss, explaining why they are more prone to skin dryness

Given these observations, a natural active ingredient enriched in galactomannans from alfalfa was developed to meet universal expectations of skin care consumers. It was obtained using a unique and patented process based on hydrolysis and purification steps The active ingredient versatility was demonstrated with an exploratory and predictive study conducted by transcriptomics on reconstructed epider mis The results highlighted that genes involved in the physical and water barrier, immune barrier, and epider mis-der mis anchoring were improved by this active ingredient To go further, the efficacy of this ingredient was investigated on fibroblasts originating from Caucasian, Asian, and African American volunteers The results revealed a significant increase of collagen I synthesis while the MMP-1 synthesis decreased in cells from all ethnicities.

From a clinical standpoint, we considered the specific concer ns of each ethnic group Consequently, five clinical studies were designed in agreement with experts from four different countries The natural active ingredient significantly improves the complexion radiance of young Caucasian volunteers in as little as 15 minutes It also increases hydration and provides a smoothing effect 7 days after the beginning of the study. In mature Caucasian volunteers, it significantly reduces wrinkles in 7 days and increases fir mness after 21 days The complexion radiance of mature Asian volunteers is significantly improved in 15 minutes and the visibility of senescent spots improves after 21 days. Young Latin American and African American volunteers have a significant improvement of the visibility of post-inflammatory spots, skin grain, and hydration after 7 days In summary, we developed an inclusive natural active ingredient effective after 7 days of initial use that responds rapidly and over the long ter m to universal cosmetic expectations

Performance Re-Evaluation of an Established In Vitro Test Method Based on a Pigmented Reconstructed Human Skin Model Used to Assess Activity of Compounds on Melanin Synthesis

The efficacy of active ingredients or finished products to modulate melanin synthesis can be evaluated using reconstructed skin models of various degrees of pigmentation In 2008, we established an in vitro pigmentation screening assay based on the Asian MelanoDerm tissue model (MatTek Corporation, USA) In our experiments, the ratio between the melanin concentration of the tissues treated with the assay controls negative (sterile-deionized water) and positive (1% Kojic acid) was at least 1.5 regardless of the length of the assay (1-3 weeks). Therefore, we concluded that notable assay sensitivity for screening melanogenesis inhibitors can be achieved using a short-ter m 1-week assay compared to the 2- or 3-week protocol established by the tissue manufacturer. The assay was used reliably until 2018, and during this time, the % tissue viability and melanin concentration endpoints’ perfor mance ranges were established

When the established assay was again used in 2023, the 1-week exposure no longer generated results for the assay controls considered acceptable within the established historical ranges Since 2018, several changes have been implemented by the tissue manufacturer to the tissue inserts and culture conditions to facilitate extending culture times often needed in screening assays evaluating pigmentation modulators Therefore, we conducted experiments to re-evaluate the established method within the current context of the test system. We used the melanin endpoint to assess the test system’s perfor mance by using the manufacturer’s current protocol and our established protocol for a 1- and 2-week extended exposure to the assay controls. Our results indicated that discrimination between the responses of the controls-treated tissues was not possible with either protocol after the 1-week exposure It was noted, however, that the ratio of the melanin concentration between controls had exceeded the established 1 5 cut-off with a greater degree of separation for our established method after the 2-week exposure time Our experiments showcase the importance of test system re-evaluation, especially over extended times of disuse. Further more, it is critical to assess the impacts that seemingly minor changes to the test system may have especially on sensitive efficacy assays evaluating activity of ingredients or finished products on melanin production.

Phyto Derivative Active for Promoting Bioregulation

in Skin

Princess-Ann George-Ezuma (Independent Chemical Corporation)

ACS-AntiCytoStressor by Vevy Europe is a hydrophilic phyto derivative active made from peptide synthesis Krameria triandra root extract is known for preventing adverse effects from stress related hormones This prevention is through bioregulation, which follows the physiological mechanisms of the integument. As proven in literature, the keratinocytes of the epider mis can self-produce stress hor mones thus generating stimuli that further produce side effects as a response This type of response can potentially be expressed in the top layer of the epidermis as an injury; however, ACS-AntiCytoStressor can modulate such activity by preventing local stress caused by wounds, hindering scar for mation

A Standardized Approach for Potency Assessment of Topical Corticosteroids

Using the Vasoconstrictor Assay (VCA)

Seeprarani Rath (Rutgers University and University of Toronto) and Isadore Kanfer (University of Toronto and Rhodes University)

Topical corticosteroids (TCs) are highly effective for the treatment of inflammatory skin conditions such as eczema and psoriasis when prescribed and used appropriately TC products are available in different potencies which depend on the specific therapeutic indication In May 2024, the Medicines and Healthcare Products Regulatory Agency (MHRA) in the UK announced that TC products must be labelled with their potencies to aid correct selection and to simplify the advice to patients requiring multiple steroid products of differing potencies 1 The potency of TCs is important because the clinical choice of a TC depends on various factors which are considered by der matologists when prescribing such products to achieve optimum safety and efficacy Potencies of TC products have usually been classified based on clinical or vasoconstrictor assay (VCA) data However, several discrepancies exist in various published potency classifications leading to ambiguity. In this work, we propose the classification of TC active phar maceutical ingredients (APIs) based on their inherent potencies using the Food and Drug Administration’s (FDA’s) VCA.

The methodology involves preparation of standardized solutions (0 0025M) of TCs in a common vehicle and application of these solutions to the forear ms of healthy human participants, followed by measurement of the skin blanching response using a chromameter The Emax model is used to fit VCA data following application of the respective TCs, and the parameters, Emax and ED50, are derived Emax is a more appropriate parameter and has been shown to correlate with potency. Hence, it is used as a metric to assess the potencies of the TCs and rank them Examples are presented of three different TC APIs associated with different levels of potencies.

The blanching response profiles for the TC APIs were deter mined and plotted The plots showed a direct correlation between the dose duration and skin blanching response, where an increase in dose duration resulted in an increase in the skin blanching response. The blanching effect peaked at 12 hours after product removal for all three TCs clobetasol propionate, hydrocortisone butyrate, and betamethasone valerate and decreased thereafter.

Fitted Emax models were derived from the Area under the Effect Curve (AUEC) values to estimate the ED50 and Emax values for the TCs Emax values were then used to rank the APIs Clobetasol propionate demonstrated the highest Emax value (-75.44 ± 15.65) followed by hydrocortisone

(continued on Page (32)

butyrate (-48 82 ± 21 90), and betamethasone valerate had the lowest Emax value (-38 01 ± 17 90) Hence, the inherent potency of clobetasol propionate was the greatest (high potency), followed by hydrocortisone butyrate (medium potency), and betamethasone valerate (low potency).

The potency of a TC may be increased or decreased based on the type of for mulation and vehicle components. Inherent potency assessment of TCs provides infor mation that will be useful when choosing an appropriate TC for the development of a TCP for a specific clinical indication Application of the VCA, when carried out in accordance with the FDA requirements, is an optimal method to assess the potency of TC APIs and for mulated TC products 2,3,4

Australian Lemon Myrtle Extract to Rebalance

Sebum Production in Melanated Skin

Florence Turgeon, Philippe Daigle and Sophia Bull (Lucas Meyer Cosmetics by Clariant)

The cosmetics industry is increasingly recognizing the importance of catering to various skin tones and types to meet the diverse needs of consumers However, individuals with darker skin still struggle to find beauty products suitable for their skin, which tends to be oilier. Highly melanated skin has larger sebaceous glands and produces more sebum compared to other skin types, resulting in an oily and shiny complexion and feelings of self-consciousness. The increased oil production also makes melanated skin more prone to acne, which can be especially challenging for this skin type, as a single pimple or breakout can cause long-lasting scars. Dealing with this daily burden is also worsened by urban living and air pollution, which exacerbate these issues more than ever Squalene, a vital component of sebum, oxidizes and becomes squalene peroxide when exposed to environmental stressors such as pollution and UV rays, leading to skin inflammation and increased sebum

production. This creates a cycle of unbalanced sebum composition and even oilier skin while also increasing the risk of developing or worsening acne due to the comedogenic effect of squalene peroxide This leaves affected individuals searching for effective or even better, preventive solutions

Extracted from the Australian endemic plant lemon myrtle, OiLESS’city was specifically designed to address this need This innovative product targets four biological factors, effectively protecting squalene from oxidation, reducing inflammation, and decreasing sebocyte differentiation and lipid production. Our comprehensive clinical trials, involving individuals aged 18 to 55 of different ethnicities, including African Americans, Asians, and Caucasians, have proven that OiLESS’city can rebalance natural sebum composition, reduce oily spots and sebum production, minimize comedones and papules, and improve self-confidence

Preservative-free, China-compliant, and sustainably produced, OiLESS'city is the optimal option for effective sebum control for individuals of all skin tones and types, including highly melanated skin.

Synthetic Hair and

Contact Dermatitis: A Systematic Review

Alexis Antonucci (V irginia Commonwealth University School of Medicine), Tiffany Mayas, M.D. (St. George’s University School of Medicine), Alina Zufall, M.D. (New York Medical College), and Shoshana Mar mon, M.D. (New York Medical College; Metropolitan Hospital Center; South Brooklyn Health)

Synthetic hair is widely used by individuals struggling with alopecia and is especially popular among people with skin of color due to its affordability and versatility While synthetic hair is generally considered very safe, the dyes and fibers within the hair may cause contact der matitis in the scalp This is likely mis-diagnosed as seborrheic der matitis or sebo-psoriasis, leading to persistence of the scalp der matitis despite treatment The purpose of this review is to investigate the association between synthetic hair and contact der matitis, both allergic and irritant, to improve our understanding and management of these patients

A systematic review was conducted following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. The literature search was conducted using the PubMed, Embase, and Web of Science databases from conception to July 2024 using the key words “synthetic hair,” “synthetic,” “wig,” “dye in synthetic hair,” “ weave, ” “artificial hair,” and “hairpieces.” Publications were included if the exposure was to synthetic hair, synthetic, wig, dye in synthetic hair, weave, artificial, and hairpieces with outcomes of contact der matitis, irritant der matitis, or allergic der matitis The study characteristics were included if they were case reports, case series, randomized control trials, or literature reviews Studies were excluded if the exposure was to hair implants, or implants; and if the study characteristic was a systematic review.

Six publications met all inclusion and exclusion criteria, corresponding to 15 total patients The hairstyles that consisted of synthetic hair were wigs in 4/15 (26.67%) patients and other hair extension types in 11/15 (73%) patients The majority of hair extensions were sewn or braided into cor nrows Patch testing was positive for phenylenediamine (PPD), a chemical in hair dye, in 4/15 (26 67%) patients and disperse dyes in 2/15 (13%) patients.

Synthetic hair can cause both allergic and irritant contact der matitis Allergic contact der matitis appears to be due to the chemicals within the dyes used to color the synthetic hair. Our findings suggest that it is important to inquire about the use of synthetic hair when evaluating and managing patients with recalcitrant scalp der matitis to avoid a delayed diagnosis of contact der matitis

Development and Validation of a Post-Inflammatory Hyperpigmentation Model in Multiple Fitzpatrick Skin Types and Multi-Ethnicities Using Three Different Induction Methods

Trevor Uher, Nora Ruth, Qihong Zhang, V ictoria Kuhr, Vanessa Kennelly, Claude Saliou, and Mei Yu (The Estée Lauder Companies)

Post-inflammatory hyperpigmentation (PIH) of the skin is caused by inflammation which triggers melanin overproduction in localized areas We aimed to develop a reliable methodology that induces PIH and evaluates its progression in different skin types and ethnicities to help assess the efficacy of treatments Three induction methods tape stripping (TS), tri-chloroacetic acid (TCA), and suction blistering (SB) were evaluated over 8 weeks and compared across Fitzpatrick skin types III-VI including Caucasian, Asian, and African American participants

TS induced less pigmentation and had a quicker recovery time after 8 weeks compared to TCA and SB. TCA and SB resulted in significant pigmentation differences when compared to baseline for Fitzpatrick III and IV skin types starting at week 2 and only at week 4 for Fitzpatrick V and VI skin types Significant redness differences were observed for all treatments in all skin types. TCA and SB showed a rapid spike immediately following treatment that remained until the week 2 time point Overall, TCA and SB

produced more consistent PIH across skin types, but we recommend the post-induction evaluation time be re-defined starting at 2 weeks and extended post 8 weeks for full resolution Overall, TS may prove useful for short-ter m evaluations and in skin types IV-VI

Inflammation is one of the most apparent acute effects of ultraviolet (UV) radiation on all the skin types, but many studies that use the UV model to investigate the anti-inflammation and antiphotoaging efficacy of topical drugs and cosmetic treatments mainly recruited skin types I-IV Despite growing research on photoaging and skin cancer on skin types V-VI, knowledge of the immediate biological responses, including erythema and vascular dynamics, is limited A double-blinded, randomized, and baseline-controlled clinical study was conducted on skin types I-VI subjects to address the response to a series of single simulated solar radiations (SSRs) on the following parameters: erythema, skin color, and blood flow/flux over 4 weeks

A 1% hydrocortisone cream was used to probe anti-inflammation activity as a positive control Fiftythree healthy female volunteers received SSR at 0 8x minimal erythema dose (MED calculated based on ITA°), 1.0x MED, 1.5x MED, and 1.5x MED followed by 1% hydrocortisone treatment for 7 days (once daily) Results suggested the dose for significant erythema induction varied within sub-skin types Blood flow, blood flux, and L and a* values showed significant increases at 24 hours and dose differences among sub-skin types Skin types I-II showed consistent inflammation responses at a minimal 1 0x MED, whereas skin types III-IV and V-VI at a minimal 1 5x MED, which suggests an adjustment factor for MED deter mination equation based on ITA° values for skin types V-VI. Further more, post-SSR pigmentation has been observed across different skin types, especially on type IV-VI starting from 2 weeks These results demonstrate a possible model and treatment window to alleviate inflammation and post-UV pigmentation and raises the importance for sun protection in different skin types We suggest future studies investigate anti-inflammatory and SPF ingredients to account for variations in different skin types

Various researchers have assessed facial skin changes overtime. Typically, these studies focus on a single endpoint on one ethnic group and on subjects aged > 30 years In a comprehensive study, the Multi-Ethnic Skin Study characterizes facial skin aging by evaluating

(continued on Page (36)

skin appearance and phenotypic science across ages and ethnicities The objective of this study is to deter mine differences in facial skin phenotypes across multiple ages and ethnic groups including surface sebum levels, stratum cor neum trans-epider mal water loss (TEWL), pigmented spots, and texture.

The study was carried out with 1250 female subjects (aged 10-80) across five ethnic groups Caucasian, Chinese, African, Indian, and Latino at three sites (two in the U.S., one in China). Facial skin was evaluated using a series of objective measures, including surface sebum levels (sebumeter), stratum cor neum TEWL (evaporimetry), and image analysis of standardized, high-resolution digital images for hyper-pigmented spots (spot area fraction) and micro-texture (texture area fraction)

A wide range of facial skin characteristics changed across all endpoints measured, from age 10 to 80 in multiple ethnicity groups.

• Facial sebum levels increased in subjects aged 20+, although maximal output differed by ethnicity: 20s for Indians, 20-30s for Caucasians, 30s for Chinese, 30-40s for Africans, and 40s for Latinos Overall, sebum levels decreased post-menopause

• Caucasian, African, and Latino subjects showed similar TEWL values from ages 10-80, while Chinese and Indian subjects had significantly higher lifetime TEWL values (peaking in the 30s), which may suggest that these two ethnicities have overall less facial stratum cor neum barrier function as compared to others.

• While texture and pigmented spots increased across all ethnicities with age, African subjects accumulated significantly more pigmented spots and skin texture than all other ethnic groups, from age 10 onwards.

Facial sebum, TEWL, pigmented spots, and texture change dynamically with aging across different ethnicities, impacting skin surface appearance and condition.

Evaluating Tinted Sunscreens to Meet the Needs for Inclusivity

Cheres Chambers (Kobo Products, Inc.)

Market research was conducted within the diverse Latin American region regarding tinted products and their inclusivity. Most brands only offered 2 to 5 shades and lacked tints for Fitzpatrick scale skin types V-VI As a result, new tints that were inclusive of Fitzpatrick scale types I-VI were created. The objective was to develop color dispersions that could be used in tinted sunscreen for mulas using mineral UV filters, avoiding any graying effect, while being mindful of limited in-store shelf space The result was the development of the KoboTint series, composite blends with high natural origin, available in 5 shades For mulas made with these blends were tested by a data color spectrophotometer, comparing the shades of foundation pallets Three different for mulations, each in five shades, were then panel tested on 134 volunteers. Inclusivity was confir med with 98.5% of the panelists able to find their shade

Skin Inflammaging Treatment with Superior Clinical Moisturizing Benefits on Melanated Skin

Nicole Terpak, James V. Gruber, Sebastien Massard, Elva Chen, and Yurah Kim (Vantage Personal Care)

People with darker skin have special concer ns for their skin care regiment especially when it comes to dealing with issues associated with highly melanated skin These individuals often have problems with acne due to the accumulation of melanin around their acne lesions driven by skin post-inflammatory hyperpigmentation (PIH) and the inflammation processes that drive acne lesion for mation In addition, individuals with darker skin often must deal with ashy skin which is the appearance of light discoloration of the skin, especially at the joints of the body, often brought on by the topical treatments they are using Especially as consumers with darker skin seek to treat conditions like acne, the treatments themselves can lead to an ashy skin appearance due to the drying effects of ingredients like salicylic acid and retinol

Vantage has developed a unique blend of polysaccharides [STRATAPHIX® POLY, INCI: Water (and) Glycerin (and) Laminaria digitata extract (and) Opuntia ficus indica stem extract (and) galactoarabinan (and) schizophyllan] that has superior moisturizing benefits including extended hydration on skin treated with retinol. This unique blend of polysaccharides has been previously shown to influence the skin’s inflammatory processes through control of the skin’s innate immune response More recent work has demonstrated that the blend is also effective at reducing inflammation in skin that has been aggravated by treatments of Cutibacterium acnes with salicylic acid. This poster will describe recent clinical studies undertaken to examine the influence of the polysaccharide blend on individuals with darker skin pigmentation (Fitzpatrick Skin Type IV-VII). Improvements in skin hydration and overall skin appearance over an extended period of treatment time (56 days) will be presented

How to Support the Oral Microbiome

Patrick Gonry (Gobiotics)

The oral microbiome not only protects our teeth and gums, but also the health of our entire body

Discover how this microbiome can be so resourceful and powerful Lear n also why we need to brush our teeth twice a day to keep the oral microbiome healthy The impact of fluorine and the beneficial effect of sugar-free chewing gum will be explained. The practical meaning of expressions such as balancing and supporting the microbiome will be uncovered Unfortunately, things can go wrong in the oral cavity. Through in-vivo testing, the supporting effect of prebiotics will be demonstrated. The effects were studied both through mouthwashes and toothpaste

Beyond the Foam: Uncovering the Many Benefits of Fermented Biosurfactants

Dennis Zhang (BASF)

Surfactants are an integral part of oral care products, providing the cleaning experience consumers seek The most used surfactant is sodium lauryl sulfate, which is under scrutiny for the potential to cause irritation in soft oral tissue. As more and more oral care players are adapting new alter native surfactants, mild and gentle surfactants are gaining popularity W ith the recent development of biosurfactants, we uncovered new features and functionalities of the fermented biodegradable surfactants besides foaming. In this session, we will lear n about the natural processing of sophorolipids (surfaceactive glycolipids) In addition, we will discuss the interaction of a specific type of sophorolipid with oral bacteria and explore its breath refreshening and microbiome balance benefits.

The Oral Health Odyssey: From Monograph to Wellness

Camille Zenobia, Ph.D. (Os Salutem)

The traditional FDA Oral Care Monograph has long shaped our focus on hygiene products, emphasizing the remin-demin cycle of enamel health However, contemporary science reveals that oral inflammation, which can spread to the gut, poses a greater threat to overall health than cavities While caries rates have declined over the past 50 years, 90% of the global population still suffers from oral inflammation This session explores how oral inflammation impacts the mouth's ecology, links to systemic health, and microbial imbalance. We'll discuss ingredients that modulate oral inflammation, revealing surprising insights into how well-intentioned oral hygiene practices can sometimes backfire and simple interventions that can improve health. Join us to lear n how to identify oral care for mulations that support your path to wellness

The Interconnection Between Oral Health and Systemic Health

Anne O. Rice, RDH, FAAOSH, CDP (Oral Systemic Seminars)

Asignificant revelation in recent years has been the recognition of the oral microbiome's pivotal role in the development of various systemic and oral diseases. A diverse community of microorganisms inhabits the oral cavity, where they coexist in symbiosis However, when there is a disruption of this microbiome balance (dysbiosis) it profoundly compromises the host's immune response, paving the way for severe pathological conditions like hypertension, diabetes, obesity, and cardiovascular disease Factors such as antimicrobial overuse, dietary shifts, decreased microbiome diversity, genetic predisposition, bacteremia, and alterations in the host immune response mediate oral microbiome dynamics Given that the mouth serves as the gateway to our body's systems, this course will explore dysbiosis, the virulence of crucial periodontal pathogens, and their correlation with different systemic conditions

Objectives:

• Identify primary contributors to oral dysbiosis and the virulence of significant periodontal pathogens

• Gain comprehension of the oral microbiota, and its correlation with various systemic conditions.

• Differentiate the mechanisms that underly the oral-systemic health link

• Recognize what and why of salivary diagnostics
