Pros and Cons of various Sunscreens
It's the season for gatherings with the family, swimming poolside celebrations, and lazy time at the beach! A day of sunshine can be a wonderful way of bonding with the family, improving mood, and obtaining essential vitamin D.
However, it does not have any hazards. The sun's radiation exposes the body to ultraviolet radiation, also known as UV Rays. UV rays are inaccessible to the naked eye. They are defined by wavelength. The most common types of UV rays include UVA, UVB, and UVC. UVA Rays have the longest wavelength then, followed by UVB and UVC. Same thing about in uses of advantages and disadvantages of lotion.
The shorter UV Rays are absorbed into the ozone layer in the atmosphere, and when your body absorbs UV radiation, most of it will be formed of UVA and a few UVB. UVB Rays are only found in the outer layer of your skin. UVA Rays penetrate deeper layers due to their longer wavelengths. While UVB Rays can cause superficial irritation and damage (like sunburn), UVA rays can cause greater damage and increase the risk of cellular damage.
The types of Sunscreen
Sunscreens' active ingredients function by creating UV filters to block harmful UV rays from the skin. There are two kinds of sunscreens, chemical, and mineral. Each has a distinct method of blocking UV radiation and protecting the skin from harm.
Mineral sunscreens
Mineral sunscreens are placed on the skin's surface. They act in the way of blocking physical rays dispersing and absorbing UV rays away from your skin's surface as tiny mirrors because they block UV radiation at the surface minerals shield against both UVA and UVB radiations.
Additionally, since mineral sunscreens act as physical barriers and are therefore efficient as soon as they are put on, so there's no need to be patient.
Mineral sunscreens usually have a whiteish tint and may be seen on the face. Because they are directly on the skin's surface, mineral sunscreens can be rubbed on, sweated, or rinsed off quickly, making frequent reapplication essential.
Also, they must be applied generously to guarantee sufficient protection. Since the nanoparticles in mineral sunscreens are not meant to be inhaled, avoiding sprays and powders is advised to reduce the risk of lung irritation. Mineral sunscreens comprise the active ingredients zinc dioxide and titanium dioxide. They can also contain a mixture of both.
Pros:
Protection against UVA and UVB Rays. Effective immediately, it won't clog pores
Cons:
It is recommended to reapply frequently to avoid leaving a white streak on the skin. Spray or loose powder formulas are not recommended.

Organic sunscreens
Chemical sunscreens get absorbed into the skin and are absorbed into the layers beneath. These sunscreens absorb UV radiation and transform them into heat. After which, they release warmth from the skin.
Since UV rays need to penetrate the skin to access the chemicals, Chemical sunscreens do not shield you from all UVA radiations, and this can cause damage to the layers beneath the skin. Since chemical sunscreens require about 20 minutes to work, It is essential to plan your time. Direct light also causes the chemicals to use up faster, meaning applying Sunscreen regularly in direct sunlight is more important. Chemicals that release heat sunscreens may be problematic for sensitive skin or rosacea-prone and those with hyperpigmentation.
The hot skin may cause an increase in the number of brown spots. Chemical sunscreens can also block pores, which can be problematic for skin with acne. Chemical sunscreens comprise Oxybenzone, Octinoxate (avobenzone), octinoxate, homosalate, octisalate, or combinations.
Pros:
A lesser amount of product is required per application to protect It is thinner and simpler to apply on the skin; it is used invisibly
Cons:
Allows some UVA exposure; it takes time to work and can cause acne, rosacea, and hyperpigmentation. Repeated application is needed.
The issue is with sunscreens that contain chemicals.
In 2021 in 2021, the FDA issued a new regulation for sunscreens sold over the counter that required any active ingredient that is absorbed into bloodstreams at levels above 0.5 milliliters to undergo toxicology tests which include carcinogenicity, developmental, and reproduction studies.
FDA researchers have reported that various active sunscreen ingredients can enter the bloodstream. The FDA recommends testing for toxicology to determine the clinical significance of these findings.
A study in 2019 investigated the concentration in plasma of Sunscreen's active components after application under maximum use. 1 In the study, 24 healthy participants applied four sunscreens to 75 % of their face every day for four consecutive days. Four active substances were tested for blood levels, including avobenzone (Oxybenzone), octocrylene, and ecamsule.
The four ingredients were within the 0.5-milliliter threshold limit within a single day of usage. In certain formulations, the highest plasma oxybenzone levels were observed at levels that exceeded 200 ng/mL.
Zinc oxide and titanium dioxide are known to have enough evidence of safety to be accepted as safe and efficient (GRASE) by the FDA, partially because the skin does not absorb them before entering the bloodstream.
For 12 of 16 sunscreen chemicals that are permitted to be used for use in the United States, there is insufficient information to allow FDA FDA to make comparable GRASE determinations. Particularly, there is concern over the oxybenzone ingredient and its potential to alter hormone levels and trigger allergic reactions.
Oxybenzone has been associated with many health risks, such as Endometriosis and low sperm quality.There could be a higher risk for pregnant women. Other studies have shown statistically significant correlations between oxybenzone exposure and adverse pregnancy outcomes such as shorter pregnancies, lower birth weights four, and an increased chance of developing Hirshsprung's disease.
A Swiss study found sunscreen ingredients, such as Oxybenzone, in breastfeeding milk. At least one sunscreen chemical was identified in 85 percent of breast milk samples that were tested. As for its impact on the natural environment, it has been found that Oxybenzone has been found that it is harmful to coral reefs of the ocean.
Making the best decision
Many factors determine the type of Sunscreen best suited to your needs and usage. Here are some guidelines to ensure you are safe from sunburns and healthy:
Look at ingredients
The most extensively studied for safety and efficacy in clinical trials include the minerals sunscreens, zinc oxide, and titanium dioxide. Most choices are available in an outdoor shop or a health food shop. If you choose to use chemical sunscreens, avoid sunscreens containing Oxybenzone as much as you can.
Select lotions
While spray sunscreens are easier to use, you should opt for an oil-based sunscreen to limit the number of airborne particles and lung exposure.
SPF numbers.
The SPF rating could lead to misapplication and a belief in security. It's much more efficient to carefully apply a product with a low SPF than relying improperly on a higher SPF product.
Apply the code correctly.
Apply a thick layer of mineral Sunscreen to get the best coverage that will be quick and effective. Apply an anti-chemical sunscreen at least 20 minutes before sun exposure.
Apply
Every Sunscreen wears off; therefore, apply it at least every two hours. This is especially true when swimming, sweating, or sweating mineral sunscreens or with direct sunlight exposure using chemical sunscreens.
Please don't skip it
Every Sunscreen will be better than none to protect your skin from damaging UV Rays.
