Abstract
The present invention concerns a product for topical application, capable of releasing a cosmetic and/or dermatological active ingredient in and/or on the skin, containing a lipase enzyme and at least one ester precursor of the active ingredient. The ester contains an ester functional group having a saturated or unsaturated, linear or branched chain having from 2 to 25 carbon atoms. According to a preferred embodiment, the precursor and lipase are packaged so as not to be in contact with one another until the time of application to the skin.
