Also known as
AA2G Vitamin C Glucoside 2-O-alpha-D-Glucopyranosyl-L-ascorbic acid Ascorbic Acid 2-Glucoside
Compatibility
Works well with:
Niacinamide Hyaluronic Acid Kojic Acid Alpha Arbutin Glycerin Tocopherol
Use caution with:
High-concentration direct acids at low pH
Ascorbyl Glucoside is notably more stable than L-ascorbic acid and is compatible with a broad range of actives including niacinamide, which can cause issues with unstabilized ascorbic acid forms. It should be added to the water phase and kept within pH 4–7 to prevent hydrolytic degradation. Avoid prolonged exposure to very low pH environments, which can cleave the glycosidic bond and accelerate breakdown.
Formulation notes
Ascorbyl Glucoside is a stable, water-soluble vitamin C derivative in which glucose is bonded to ascorbic acid via a glycosidic linkage. Upon skin absorption, cutaneous glucosidases cleave the bond to release free L-ascorbic acid, delivering antioxidant protection, melanogenesis inhibition, and collagen synthesis stimulation. Formulators favor it over L-ascorbic acid for its significantly improved stability, broader pH tolerance, and gentler skin profile.
