Ascorbyl glucoside is a stable form of vitamin C combined with glucose. When properly formulated and absorbed into skin, it breaks down to ascorbic acid (pure vitamin C).2-O-a-D-Glucopyranosyl-L-ascorbic Acid is a useful cosmetic gel and skin cleanser. Once absorbed, its breakdown to vitamin C is gradual, creating what’s known as a reservoir effect within skin. This leads to longer-lasting benefits.
Biochem/physiol Actions
2-O-a-D-glucopyranosyl-L-ascorbic acid or ascorbyl glucoside functions as a skin whitener and radical scavenger in cosmetics. It is responsible for the bleaching action of bleaching cosmetics. This compound is activated in a manner identical to that of vitamin C. The enzyme present in the epidermal basal membrane, ascorbyl phosphatase, slowly converts 2-O-a-D-glucopyranosyl-L-ascorbic acid into vitamin C, thereby maintaining a high vitamin C level in skin throughout the day.
부작용
While pure vitamin C can sting and cause mild irritation, there aren't any side effects we know of with ascorbyl glucoside, says Nussbaum. Still, it is an active ingredient for sure, so you can always test out a small amount elsewhere on your skin to make sure you can tolerate it.
