Title: Rejuvenating the skin using a combination of vitamin A and alphahydroxy acids

Abstract: Methods of accelerating skin rejuvenation and methods of skin care treatment are disclosed using a combination of vitamin A and alphahydroxy acids, such as the combination of vitamin A propionate and glycolic acid. The combination can be prepared in an alcohol-based carrier having concentrations ranging from approximately 0.01% to 10% vitamin A propionate, preferably 0.1% to 4%, and 0.1% to 30% glycolic acid, preferably 2% to 10% glycolic acid. In addition to alcohol, the carrier may also include propylene glycol, preservatives, thickeners and non-ionic surfactants or may be a cream or ointment-based formulation. The formulation is applied topically to the skin at a frequency which will produce a fine desquamation. The formulation may also be used to accelerate the penetration of other therapeutic agents into the skin.
