Promacare-EAA 3-o-ethyl Ascorbic Acid

PromaCare-EAA is a derivative of ascorbic acid, one of the most excellent derivatives so far. It is very stable in chemical structure, and it is a genuine stable and non-discoloring derivative of ascorbic acid, with better performance than other ascorbic acid derivatives, because its metabolic pathway is the same as Vitamin C after it penetrates the skin. High bioavailability, being easy to penetrate the cuticle to enter the dermis, and be converted to vitamin C by bio-enzyme. Stops melanin production by inhibiting tyrosinase activity. Preventing skin inflammation caused by sun light; improves skin color. Boosts collagen production, thereby increasing skin elasticity.
