What is 3-O-ethylascorbic acid?

3-O-ethyl ascorbic acid, also known as vitamin C ethyl ether, is a lipophilic and hydrophilic vitamin C derivative, which not only makes it extremely convenient to use in formulas, but also makes it easier to penetrate the stratum corneum and enter the dermis. After entering the skin, it is easily decomposed by biological enzymes to play the role of vitamin C, thereby improving its bioavailability.

However, ordinary vitamin C is difficult to be absorbed by the skin and has low bioavailability. In addition, vitamin C ethyl ether also shows extremely high stability relative to ordinary vitamin C.

Used of 3-O-ethyl ascorbic acid

1. Ethyl ascorbic acid ether directly participates in the synthesis of collagen after entering the dermis (the hydroxylation of proline requires active vitamin C to participate in the synthesis process), repairs the activity of skin cells, increases collagen, and makes the skin plump and rich Elasticity, making skin delicate and smooth.

2. Inhibit tyrosinase activity (the rate-limiting enzyme in the process of melanin synthesis, which directly affects the synthesis of melanin), inhibit the formation of melanin, and restore melanin to colorless, effectively whitening the skin.

3. It has a very good anti-oxidant effect in cosmetics, and truly achieves the effect of whitening and freckle removal.

4. The skin is easy to absorb and can reach the dermis through the stratum corneum

5. It has a strong antibacterial and anti-inflammatory effect, which can eliminate some inflammation caused by sunlight.
