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

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.

The present invention relates to gelled emulsion particles obtained when predetermined volumes, especially drops, of an emulsion with an aqueous external phase, containing an appropriate reagent in solution in the said aqueous phase, are added to a gelling solution and left therein for a period of time which depends on the degree of gelling desired for the said particles. It further relates to compositions--especially solutions, gels or emulsions with an aqueous external phase--in which the said particles are present.

Gelled emulsion particles and the compositions in which they are present

Extracts of periwinkle seed, obtained by bioconversion, and compositions containing such extracts display the property of stimulating mitochondrial cell respiration and of stimulating the cell growth of fibroblasts and keratinocytes. Such extracts and compositions also exhibit activity against oxygen free radicals.
