Abstract

Abstract Noninfectious inflammatory and hyperpigmentation skin diseases, thermal injuries and premalignant skin tumors induced by radiation or virus, in both humans and animals, are treated with topical formulations of an ester or amide of a monocarboxylic acid, the acid moiety of which is 9 to 18 carbon atoms.
