The active ingredients in sunscreen create an important layer of protection between your skin and the sun’s UV rays. But what is the mechanism by which these components work? This blog will lead you to learn how chemical and physical filters work together to provide outstanding protection against UVA and UVB rays for healthy skin.
How Does the Ingredient in Sunscreen Protect Against UV?
To understand how the active ingredients in sunscreen protect against UV rays, it is important to understand sunscreen product design. The purpose of sunscreen is to protect the skin from harmful UV rays, of which there are two types: UVA and UVB. They do this by absorption, reflection, or refraction.
Key Active Ingredients for UV Protection
The degree of protection a sunscreen offers depends on some active ingredients in it. Some of those key ingredients noted for their protective properties include:
Bisoctrizole / BFP-SP M (Tinosorb M)
Bemotrizinol/ BFP-SP S
Diethylamino Hydroxybenzoyl Hexyl Benzoate/BFP-SP DHHB
Ethylhexyl Triazone/BFP-SP EHT
Octocrylene/ BFP-SP OCT
Avobenzone/ BFP-SP AVB
These ingredients, organic UV filters, absorb injurious rays well.
Role of Antioxidants in Sunscreens
Antioxidants’ role in sunscreens is essentially to enhance the efficacy of sunscreens. They act by helping to neutralize free radicals created by UV radiation and therefore reduce the rate at which there is oxidative stress in the skin. Though not the main actors in preventing UV transmission, antioxidants provide more value to sunscreen formulations by offering extra protection against environmental aggression.
Why Is SPF Not the Sole Factor to Consider?
SPF is a better-known metric about the effectiveness of a sunscreen product in filtering out UVB rays, but that does not make it the only metric critical to any sunscreen product. A better understanding of all the different elements will provide one with the best possible sun protection.
Broad Spectrum Protection Explained
Broad-spectrum protection involves a product’s ability to protect users from both UVA and UVB rays. Protection against both elements would mean that the user is protected from an aging process promoted by the UVA rays and damage that is usually caused long afterward. Zinc oxide-based sunscreens are perfect examples of products that offer protection within both spectrums.
Water Resistance and Impact on Performance
The water resistance of any sunscreen product directly or otherwise affects its performance. A water-resistant product will not be dissolved by water or sweat; thus, its content will remain on the skin even in wet conditions. This is a core factor for athletes who compete outdoors or in the water.
What Are the Regulatory Standards for Sunscreen Ingredients?
Regulatory standards ensure the safety and efficacy of sunscreen ingredients across different regions globally. Understanding these regulations helps manufacturers comply with local guidelines while ensuring product quality.
International Standards and Comparisons
Different countries have adopted their own regulatory frameworks concerning the manufacture of sunscreens. Most of these usually relate to allowable concentrations of active ingredients and what is to be represented on the label of the products.
Regulations on Sunscreen Ingredients
EU
The European Union has strict regulations on cosmetic products, in which sunscreens are included. The EU Cosmetic Regulation provides for the safety assessment and substances presenting risks to consumer health.
FDA
The Food and Drug Administration classifies sunscreens in the United States as over-the-counter drugs. The FDA governs the process to determine SPF values. A broad-spectrum sunscreen claim has to meet certain qualification criteria outlined by the Agency.
