Stabilization of ascorbic acid, ascorbic acid derivatives and/or extracts containing ascorbic acid for topical use

摘要

A stable composition is provided to treat and/or prevent photo-aged skin and related skin disorders such as sunburn, wrinkles, poor skin tone and skin discoloration by topically applying to the skin the treatment composition containing an effective amount of a compound such as ascorbic acid, derivatives of ascorbic acid and/or extracts containing ascorbic acid, in a pharmaceutically acceptable vehicle containing a substantially anhydrous base having no water added. The anhydrous base stabilizes the compound, so that the compound remains effective for an effective period of time, even in the presence of exposure to water. Preferably, the anhydrous base is a single phase carrier, as opposed to a two phase carrier emulsion.
