Ingredients

23% pure vitamin C helps brighten the complexion and support more even-looking skin tone.

Vitamin C (L-ascorbic acid) donates electrons to neutralize free radicals before they can damage collagen fibers and DNA. It also inhibits tyrosinase, the enzyme responsible for melanin overproduction, which is why it simultaneously brightens existing discoloration and prevents new spots from forming. The antioxidant effect compounds with sunscreen, providing a second line of defense against UV-induced aging.
