Ethyl Ascorbic Acid is the best derivative of vitamin C so far. With very stable chemical properties, it is anon-discoloring derivative of vitamin C in its true sense. Ethyl Ascorbic Acid is metabolized in the same way as vitamin C in human body after entering the skin, which helps vitamin C play a better role. More importantly, the amphipathy of VCE makes it easier to permeate the stratum corneum and reach the stratum basale to produce more biological effects. So ethyl ascorbic acid is the best choice for developing whitening cosmetics.
