Ascorbyl glucoside is a stable derivative of Ascorbic Acid produced by the enzymatic bonding of a glucose molecule to the hydroxyl radical at C-2 of Vitamin C. When applied to the skin, it hydrolyzes into Vitamin C and Glucose by α-glucosidase, an enzyme naturally present in cell membranes. This natural enzyme releases Ascorbic Acid, which is assimilated by membrane transporters, exerting the same biological antioxidant activity in the body as the original Vitamin C. Unlike Ascorbic Acid, which requires an acidic pH to stabilize and penetrate the dermal layer, Ascorbyl Glucoside remains stable for extended periods at the skin's pH of 5,5. Ascorbyl glucoside has a great importance because of its safety, stability, and well-established release mechanism.
