1. Brighten the skin tone and inhibit the formation of melanin. After ascorbyl glucoside is converted into vitamin C and enters the skin cells, it can significantly reduce the formation of melanin by inhibiting the activity of tyrosinase. Inhibition of tyrosinase reduces dopaquinone, an intermediate in the synthesis of melanin. Another added benefit is the simultaneous conversion of dopaquinone into Chemicalbook's levodopa, which relieves the melanin that has formed, thereby reducing skin pigmentation. 2. Resist UV damage and inhibit the damage to cells caused by ultraviolet radiation. After ascorbic acid glucoside is converted into vitamin C, it can greatly reduce the free radicals generated by ultraviolet radiation on the skin, significantly reduce skin damage, and protect the skin in sunscreen products. .
