What does THD Ascorbate (Vitamin C) do for your skin? Retrouvé uses an oil-based, pharmaceutical-grade Vitamin C that provides a more even skin tone for brighter-looking skin. THD Ascorbate is also considered to be not only more stable but also more potent than L-ascorbic acid and many other Vitamin C compounds. THD Ascorbate also offers deeper penetration than other derivatives because it is lipid soluble, like human skin, while providing a higher rate of conversion to Vitamin C.
