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.

Abstract: 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.

Abstract: The invention relates to a composition, which may be cosmetic or dermatological, Containing at least one dihydroxyacetone precursor. The invention also relates to a composition, which may be cosmetic or dermatological, containing at least one dihydroxyacetone precursor and a compound capable of converting this precursor into dihydroxyacetone. Finally, the invention relates to such a composition packaged in a specific manner and to the use of the composition for artificial tanning of the skin.

Abstract: 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.

Abstract: Cosmetic composition in the form of an aqueous gel containing a gelling agent and an aqueous medium, in which the gelling agent consists of a mixture of:a) at least one at least partially neutralized, crosslinked acrylic acid polymer having a molecular weight of between 700,000 and 4,500,000 approximately,b) at least one at least partially neutralized copolymer of acrylic acid and vinyl monomer bearing amine, amidine and nitrile functions, and obtained by hydrolysis of polyacrylonitrile, having a molecular weight of between 100,000 and 200,000 approximately, andc) at least one polyethylene glycol having a molecular weight of between 10.sup.5 and 3.times.10.sup.7 approximately.

Abstract: A cosmetic or pharmaceutical water-in-oil emulsion composition, exhibiting time and temperature stability, comprises in an aqueous phase, (a) a fatty phase comprising (i) a silicone and (ii) a gelling agent and (b) an emulsifying agent. The fatty phase is present in an amount ranging from 15 to 40 weight percent of the emulsion and contains 10 to 90 weight percent of the (i) silicone and 0.1 to 5 percent of the (ii) gelling agent. The emulsifying agent is present in an amount ranging from 0.5 to 10 percent by weight.
