Ethyl ascorbic acid is a molecule produced by modifying ascorbic acid, commonly known as vitamin C. This modification is done to increase the molecule’s stability and enhance its transport through skin, as pure vitamin C is easily degraded. In the body, the modifying group is removed and vitamin C is restored in its natural form. Thus, ethylascorbic acid retains the benefits of vitamin C, such as antioxidant activity. Furthermore, it is even more potent in reducing skin darkening after UV exposure. It even has some additional effects, not observed in pure ascorbic acid, such as promoting nerve cell growth or reducing chemotherapy damage. Finally, the slower release also ensures that no toxic effects are observed when using this vitamin C derivative.
