The chemical formula of ASCORBYL GLUCOSIDE is C12H18O11 which containing 12 Carbon atoms,18 Hydrogen atoms and 11 Oxygen atoms,and the molecular weight of ASCORBYL GLUCOSIDE is 338.268.
Ascorbyl glucoside is a natural active substance containing Vitamin C structure, but it is stable. Ascorbyl glucoside can effectively inhibit formation of melanin, dilute the skin color, reduce age spots and freckles pigmentation.Ascorbic Acid 2-Glucoside(AA-2G) was originally developed as a quasi-drug cosmetic product in Japan to lighten the overall tone of the skin and reduce the pigmentation in age spots and freckles. Further research has shown other dramatic benefits and today AA-2G is used all over the world-not only for whitening but also for brightening dull looking skin, reversing the effects of aging, and in sunscreen products for protection.
