Abstract
A cosmetic composition is provided which includes ascorbic acid (Vitamin C) stabilized by dimethyl isosorbide in a pharmaceutically acceptable carrier. Among the preferred carriers are polyols such as polyethylene glycol, propylene glycol and mixtures thereof. Aesthetic properties are improved by the presence of a crosslinked non-emulsifying siloxane elastomer and a volatile siloxane.
