Ascorbyl glucoside (AA-2G) is an ascorbic acid derivative that contains at least one glycosyl group. Ascorbyl glucoside is commonly used in cosmetic products to administer vitamin C topically. Ascorbyl glucoside exhibits superior stability and penetration ability compared to ascorbyl phosphate salts, but the rate of its in vivo conversion to ascorbic acid is not known.[1] Ascorbyl glucosides such as AA-2G, like many other derivatives of the ascorbic acid, show antiscorbutic effects.[2] It is also sometimes used in skin whitening products.[3]

Ascorbyl glucoside is synthesized through a glycosylation process catalyzed by glycosyltransferase-class enzymes.[3]
