Abstract
Topical compositions for application to the stratum corneum include a polyester and an active ingredient which is a chemical exfoliating agent, sunless tanning agent, skin lightening agent and/or an insect repellent. The polyester substantially retains the active ingredient on or in the stratum corneum. A method for improving the effect of the active ingredient in a topical composition includes providing a polyester which functions to substantially retain the active ingredient on or in the stratum corneum to improve the effect of the active ingredient.
