Abstract
A stabilized composition capable of releasing an active agent in contact with the skin, contains at least two precursors of this same active agent, capable of simultaneously releasing this active agent by at least two different specific enzymatic reactions in order to release a large amount of active agent at a faster rate than the sum of the rates of the first enzymatic reaction and of the second enzymatic reaction taken separately, the first precursor being chosen from active agent monosaccharide derivatives and active agent amides. The composition is useful for dermatological and/or cosmetic treatments applied topically.
