Skin Structure
The Skin
Epidermis HornyCYTES: Cell without nucleus full of cheratin
Horny layer
DESMOSOMES: Structures holding cells togheter MELANOCYTE: Cell that manufactures melanin, that migrates in basal Hornycytes through desmosomes You find a melanocyte evey 30 or 40 Hornycytes. It produces melanin for all the surrounding korneocytes
Granulous layer
Spiny layer
Basal layer
NUCLEUS Of CHERATINOCYTES
Dermis
Arrector pili muscle
Sebaceous gland: Secretes sebum, a natural anti-wrinkles that partake in the formulation of the hydrolipidic film
Collagen fibres (horizontal) and elastine (vertical): These fibres make skin elastic, tonic and compact
Hypodermis Hair bulb
Adipose lobule Adipocytes lives toghether in lobule. Each lobule is rich of blood
Apocrine sweat gland Throgh pilosebaceous duct its secretions form the hydric fraction of hydrolipidic film
Hydrolipidic film Hydrolipidic film in healthy condition: Skin is healthy, moisturized, tonic and presents a regular daily evaporation of water
If hydrolipidic film is compromised, skin loses elasticity and appears chapped, determining an increase of cutaneous evaporation
Water molecule Hydrolipidic film
Horny layer
NB Daily transepidermic water loss (TEWL) amounts on average 600 cc
If hydrolipidic film is damaged, epidermis, dermis and hypodermis suffer because of lack of barrier
Il pH Il pH is a measure of acidity or alcalinity of a solution Most substances have a pH in the range 0 to 14
Hydrolipidic film Cutaneous pH
Horny layer
Macrofagi
Skin and hydrolipidic film have an average pH value of 5.5; acidity is due to the sectetion of sebaceous glands, consisting of unsaturated fatty acids. Its main purpose is to act as a barrier against viruses, bacteria and irritant substsances pH

If pH is altered If cutaneous pH hasn’t a correct acid value, the protective mantel becomes thinner and thinner, until it chaps or misses: the main consequence is its corruption and the appearance of micro-chaps Hydrolipidic Film

Macrofages
Viruses and bacterias
Virues, bacteria and pollutants find no barriers, so they can easily penetrate into cutaneous tissue
Cleaning There are several cleansing products that have different actions and consequences
Hydrolipidic Film
soap
Cutaneous pH Impurities
Horny layer
Cleansing Emulsion emulsione detergente
Hydrolipidic Film SOAP Horny layer
As time passes, micro-chaps appear, causing an abnormal epidermic evaporatin and penetration of bacteria Hydrolipidic Film
Soap is generally alkaline and it completely alters cutaneous pH. Moreover it doesn’t perfectly remove make-up As a consequence: Impurities aren’t removed Cutaneous pH is altered Hydrolipidic film is almost all compromised
pH
CLEANSING EMULSION
Cleansing milk is generally neutral, it perfectly removes impurities, preservig the correct value of cutaneous pH and hydrolipidic film
TONICO
Toner is indispensable to quickly restore skin physiological values and cutaneous barriers
Exfoliators Skin in healthy conditions: Pores are free and can constantly support hydrolipidic film and cutaneous pH
Because of a slow exfoliation, thicknesses can form on epidermis upper layer
Hydrolipidic Film pH
Impurities Epidermis
Catabolites and toxines
Melanocyte
Pilosebaceous duct
This thickening of the Hornyus layer can obstruct pilosebaceous and sweat ducts, compromising hydrolipidic film and pH integrity
Exfoliating - action Exfoliators remove and eliminate Hornyus layer thickening
Epidermis
Impurities Catabolites and toxines
The regular use of exfoliating products guaranties a correct cellular regeneration, skin renovation and mantains efficent skin pores A weekly use of these products, helps to mantain skin glowing and smooth, but above all protected, in fact cutaneous pH and hydrolipidic film are mantained functional and integer
Day Creams
Sun exposures and tanning lamps thicken Hornyus layer hindering skin in and out exchanges : The consequence is low superficial hydration, and a lungo andare, low lipids apport. As a consequence hydrolipidic film deteriorates and skin is unprotected
Cold compromises blood microcirculation, so that capillaries are vasoconstricted: as a consequence constant hydration, nourishment and oxigen lack, skin gets thinner and more sensitive, and unsostained hydrolipidic film is destroyed
Smog and pollution create an occlusive film that hinder skin breathing, in fact oxigen bonds to toxin film more easily than to epidermic cells: skin becomes asphixial and hydrolipidic film is damaged
Day Creams - action supplies: protection specific active ingredients according to aestetic need hydration
WIND AND COLD
POLLUTANTS
SUN
Epidermis
Constant use of daily cream protects skin, helping restoration of hydrolipidic film and physiological pH. Cellular rigeneration is enhanced apporting foundamental substances while natural exfoliation is favoured by correct cellular cohesion
Night Program During night time skin cells aren’t stressed, thet then work quicklier: this is the phase when they work more quickly and there is a maximum cell regeneration With night cream we support: nourishment specific active ingredients according to aerstetic need hydration
Epidermis
The constant night program use provides up to basal layer the nourishing substances essential to cellular regeneration: skin finds its strenght, elasticity, cohesion, and is again able to efficently act as a barrier. Functional substances sinergy involves the restoration of hydrolipidic film and physiological pH, a guarantee of health for skin.
The ground substance is conslidated and incremented, giving tone and compactness to skin. The peculiar formulations recreante a mini-professional treatment
Serums Daily use of a specific serum for the individual aestetic need or for seasonal need, permits to strengthen skin, re-estabilishing damaged structures from inside . The slight blemish will quickly regress and skin will appear globally more lively
Blood and lymphatic microcirculation are stimulated, fibroblasts begin to fully work again, collagen and elastin fibres are more solid ad resistant and a better hydration favour metabolism and intercellular exchanges. Hydrolipidic film and cutaneous pH are reestabilished and supported from inside, skin looks more compact
= hydration = specific active ingredients for aestetic need
Serum + Cream Epidermis Dermis Hypodermis
Skin exposed to dailiy stress, with evident slight blemishes and epidermic micro-chaps SERUM
Serum acts deeply, healing the dermic Dermis structures and favouring a quick rebalancing of Hypodermis epidermic structure Epidermis
The perfect cuopling between serum and day or night cream, makes skin globally healthy: Serum acts deeply on aestetic need withoout Epidermis leaving protection on epidermis Dermis Day and night creams favour a quick reestablishment of epidermic structure, moreover Hypodermis protecting it from external aggressions. The two actions give a concrete and stable in time result
