Use of 2-O-alpha-D-Glucopyranosyl-L-ascorbic Acid cosmetic grade

2-O-alpha-D-Glucopyranosyl-L-ascorbic Acid is mainly used in high-grade cosmetics as a skin lightening agent and whitening agent.
2-O-alpha-D-Glucopyranosyl-L-ascorbic Acid is a natural active substance containing vitamin C structure and it is a good VC derivative.
The experiment proves that 2-O-alpha-D-Glucopyranosyl-L-ascorbic Acid not only overcomes the shortcoming that VC is easily oxidized and unstable, but also has excellent stability under the condition of heat, oxygen and metal ions, and retains the normal activity of VC. The role of the skin, the slow release of vitamin C, can effectively exert its ability to inhibit melanin, reduce color, reduce pigmentation. 2-O-alpha-D-Glucopyranosyl-L-ascorbic Acid also has a bright skin, anti-oxidation, anti-aging skin, play a role in protecting the skin in sunscreen products.
