Ascorbic Acid

Ascorbic acid’s main use in skincare is for de-pigmentation. It achieves this by suppressing melanin formation thereby inhibiting pigmentation. It is used in products to address skin aging spots, melasma, post-laser erythema, and stretch marks.

Ascorbic acid is very unstable when exposed to light or air, ascorbic acid not only becomes inactive, but it also oxidizes extremely fast to become dehydroascorbic acid (DHAA), which further degrades to acids that are very irritating to the skin. In other words: the best-case scenario is that you’ll have a useless product; at worst the oxidation process creates even more free radicals and acidic by-products, which are very damaging for the skin.

Benefits:
Vitamin C promotes collagen production, which has the potential to thicken the dermis, diminish fine lines, and is essential for firm, youthful skin.
