3-O-Ethyl-L-ascorbic acid is a product of ascorbic acid-3-O-ethylation. It has a simple molecular structure and is easily absorbed by the skin. After entering the dermis through the stratum corneum of the skin, it is easily decomposed by the biological enzymes in the human body. The effect of ascorbic acid effectively solves the fat solubility problem of ascorbic acid, and is widely used in cosmetics as a whitening agent and antioxidant.

??

3-O-Ethyl-L-ascorbic Acid could be a useful stabilizing agent for a para-hydroxyacetophenone solution. It could be a useful stabilizing agent for a para-hydroxyacetophenone solution.

Mechanism of action

VC ethyl ether penetrates the stratum corneum to reach the melanocytes in the basal layer, inhibits tyrosinase activity, inhibits the formation of melanin, and restores melanin to colorless, thereby effectively whitening the skin. And Chemicalbook and VC ethyl ether can directly participate in the synthesis of collagen and repair skin cell activity after entering the dermis, increasing collagen, so that the skin becomes full and elastic, making the skin delicate and smooth.
