Abstract
Abstract Skin diseases resulting from abnormal metabolic processes, such as acne and psoriasis, are treated on a repetitive basis, either internally or topically, with a dermatologically sufficient amount of 11-(2',6',6'-trimethylcyclohex-1'-enyl-1')-5,9-dimethylundeca-2,4,6,8, 10-pentenoic acid or its physiologically acceptable salts to reduce the inflammation. The subject acid or its salts are found to provide remission of the dermatologically diseased condition, while avoiding side effects concommitant with the use of other analogous compounds.
