Description and Uses

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.

2-O-alpha-D-Glucopyranosyl-L-ascorbic acid reduce the free radicals that result from UV irradiation of the skin, and significantly reduce cell damage and photo-aging. It also promotes collagen synthesis. It can function as an antioxidant.
