Ascorbyl Glucoside (AA2G) Stable Vitamin C
Número CAS: 129499-78-1
Ascorbyl Glucoside (AA2G) is an enzymatically synthesized conjugate of ascorbic acid and glucose, designed to overcome the notorious instability of pure L-ascorbic acid. Upon skin absorption, glucosidase enzymes cleave the glucose moiety to release bioactive free ascorbic acid directly where needed. It delivers the same brightening, collagen-stimulating, and antioxidant benefits as L-ascorbic acid at 0.5–3% without oxidation-driven discoloration or pH restrictions.
