Dehydroascorbic acid

edited October 2016 in Ask the Beauty Brains
Hey Randy and Perry.

Does dehydroascorbic acid (DHA) have a similar effect to ascorbic acid (AA) when applied to skin? There are some claims that it penetrates easier, it can convert back to ascorbic acid and if combined with AA then less AA is needed to have an effect on the skin. All of this information comes from a company that sell vitamin C serums so I’m obviously highly skeptical. But it would be nice to know if there’s any science to back this up.
