UVB/UVA Sun Rays

Why sunless tanning is safer for your skin

Although we all would love to radiate that sun-kissed glow, research has shown that tanning beds and increased sun exposure can create irreversible damage to our skin. Here are a few facts about UVA and UVB rays, which will help clear up any misconceptions.

What Are UVA and UVB Rays?

UVA rays are believed to penetrate deeply into the skin, causing damage to collagen and cells that are in the dermis (under layer of the skin). UVB rays are shorter, more powerful rays that affect the epidermis (outer layer of skin) and are responsible for the sunburns we get when our skin is unprotected.

Aging and Wrinkles

Exposure to UVA rays can damage elastin, a protein fiber that gives skin the ability to snap back into shape. UVA rays can cause wrinkles, sagging, dryness, and uneven skin tone. UVB rays tend to be more intense at higher altitudes and during summer months. Research shows repeated exposure to UVB rays can affect the immune system and lead to skin cancers.

Sunscreen Protection

Be sure to protect from harmful UVA and UVB rays with a good sunscreen, which will filter and block these damaging rays. L’Oréal is proud to offer products featuring RevitaLift® UV with Mexoryl SX, the first sun filter to be approved by the FDA in 18 years. Endorsed by dermatologists worldwide, it is the most effective organic filter designed to protect against short UVB rays, not just long UVA rays. Still, the best protection is staying out of the sun completely. So for a safe sun-kissed look, try Sublime Glow for gradual natural-looking color and Sublime Bronze for an instant golden tan.
