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