AA2G® (Stabilized Vitamin C)

For healthier, brighter, younger looking skin

AA2G® is a stabilized Vitamin C derivative synthesized from vitamin C and starch by the use of enzymes.  When used in skin cream, AA2G® delivers healthier and younger looking skin over a prolonged period by the activation properties of natural enzymes in the skin.

Vitamin C (ascorbic acid) has multiple functions in the human body, but it is relatively unstable and easily oxidized in aqueous solutions, which is followed by rapid degradation.  In contrast, in AA2G® vitamin C is stabilized with glucose.  AA2G® is a conjugate consisting of one molecule of glucose linked at the C-2 hydroxyl radical of vitamin C.  AA2G® is non-reducible and very stable to oxidative conditions.

AA2G® has the same biological activity in the body as Vitamin C. It is hydrolyzed into Vitamin C and glucose by α-glucosidase, the enzyme naturally existing in cell membranes in the body, including the skin.

AA2G® is gradually converted into active Vitamin C in the skin, so it has a greater sustained effect than conventional vitamin C. Its application in skincare products, in addition to its use as a brightening agent, is primarily in moisturizing and sunscreen products for everyday use. This includes cosmetics to prevent photo-aging and anti-wrinkle cosmetics.  All these applications are supported by several studies.

Studies have confirmed that AA2G® is safe when used topically.  AA2G® is a cosmetic ingredient for use in skin creams and lotions.

INCI name:  Ascorbyl Glucoside
