SUN DAMAGE & SUN PROTECTION
The sun is the source of energy that sustains life, but accumulated exposure without proper protection has negative consequences. Three main types of rays that damage our skin are UVA, UVB, and infrared rays (IR), all of which have the ability to penetrate skin and cause damage to cells and DNA. On the surface, this damage manifests as fine lines, wrinkles, laxity, and discoloration, but the most dangerous consequence beneath the surface is the risk of skin cancer.
To adequately shield skin from the sun, sunscreen needs to be a part of every daily routine. Options include physical UV-reflecting ingredients, chemical UV-absorbing ingredients, or a combination of both, but the most important thing to look for on a label is the term "broad spectrum". This indicates full coverage from the entire spectrum of UVA and UVB radiation, whereas SPF only measures the length of time one is protected from the UVB rays responsible for sunburn.
Research has shown that sunscreen alone does not provide adequate protection from environmental damage. A key finding shows that the average consumer does not apply enough sunscreen, therefore only obtaining up to half the protection stated on the bottle. Second, sunscreens only block 55%* of the free radicals generated by UV exposure. Finally, UV filters do not provide protection from damaging infrared radiation. For broad range protection against all sources of environmental skin insults, it’s imperative to use a topical antioxidant in conjunction with a daily sunscreen. Skinceuticals offer antioxidant products that have been clinically proven to provide optimal protection from the damage caused by UV rays and other environmental factors.
