Ascorbyl glucoside NEW

Efficacy and function

1. Brightening skin tone inhibits the formation of melanin After the conversion of ascorbate glucoside into vitamin C into skin cells, it can significantly reduce the formation of melanin by inhibiting the activity of tyrosinase. Inhibition of tyrosinase reduces dopa quinone, an intermediate in the synthesis of melanin. An added benefit is the simultaneous conversion of dodoquinone into levodopa, which alleviates the formation of melanin, thereby reducing skin pigmentation.

2. Resist UV damage Inhibit UV radiation damage to cells after the conversion of ascorbate glucoside into vitamin C, it can greatly reduce the free radicals generated by ultraviolet radiation in the skin, significantly reduce skin damage, and play a role in protecting the skin in sunscreen products.

Apply

Ascorbate glucoside, one of the whitening additives approved by the Department of Health, is recognized as the most stable vitamin C derivative. At the same time, it is also the most commonly used whitening ingredient of major brands. For example, L 'Oreal uses C-glycoside derivatives in synergy with other components to prevent or treat signs of aging in the body or facial skin. Ascorbate glucoside not only has a good whitening effect, but also has a stable chemical property and no irritation to the skin, which is widely used in cosmetics at home and abroad, and has been recognized by the public. The following table lists the application of common vitamin C derivatives in cosmetics.

Whitening principle

The content of melanin in human skin determines the color of skin, and the cooline is the main raw material for the production of melanin. Tyrosinase is the rate-limiting enzyme in the pathway of tyrosine synthesis, which mainly affects the production of melanin by affecting the conversion of tyrosine into dopamine and the oxidation of dopamine into dobacone. The mechanism of ascorbate glucoside whitening is to inhibit the production of melanin by inhibiting the activity of tyrosinase with L-cooline as the substrate. The whitening principle can be confirmed by the following picture.
