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.

Product for topical application containing a lipase and a hydroxy acid precursor

Stable, topically applicable cosmetic/dermatological compositions well suited for artificially tanning or browning human skin and appropriately packaged, comprise at least one dihydroxyacetone (DHA) derivative convertible into DHA and, advantageously, at least one active species for effecting such conversion.

Active/stable artificial tanning compositions comprising DHA derivatives

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.
