A delivery system for topically applied compounds is disclosed. The delivery system contains a fatty acid, a phospholipid, and an oil, and is activated by the addition of water. The delivery system is admixed with a topically applied compound and water to provide a composition suitable for application to the skin or hair. The relative amounts of delivery system ingredients provide round, flexible vesicles that allow penetration of the topically applied compound to the epidermis and dermis, vesicles having a partially ruptured membrane for a controlled delivery of the topically applied drug to the epidermis and dermis, completely ruptured vesicles in the form of lamellar sheets that allow the topically applied compound to be retained in the stratum corneum, and mixtures thereof.
