Abstract
A preparation for topical application of linoleic acid, for treatment of acne, and Propionibacteriem acnes, contains between about 0.1% and about 10%, preferably between about 1% and about 5% and specifically about 2% of linoleic acid. This acts both as an antibiotic and as a means for correcting the essential fatty acid imbalance in sebum which causes follicular plugging and triggers the process.
