Abstract: The invention concerns a make-up or coloring method comprising steps which consist in imaging at least one part of the human body to be treated, analysing local characteristics of said part, and applying treatment products of said part based on said local characteristics.

Abstract: Topically applicable photostable sunscreen/photoprotective compositions contain at least one dibenzoylmethane UV-sunscreen and an effective photostabilizing amount therefor of at least one amphiphilic block copolymer which comprises at least one nonionic hydrophilic polymer block and at least one hydrophobic polymer block, formulated into a topically applicable, cosmetically acceptable medium therefor.

Abstract: The use of a composition comprising at least one organometallic compound which may be obtained by partial or total hydrolysis, and partial or total condensation, of at least one metallic precursor, to at least one of protect and strengthen a keratin material.

Abstract: A kit for dyeing keratin fibers, for example, human hair, comprising a basifying composition and an oxidizing composition comprising a molecular complex comprising at least one organic acid and at least one direct dye, as well as the oxidizing composition of the kit and the dyeing process using this kit.

Abstract: The invention relates to a process for densification of the hair, comprising a stage of application to the hair and/or the scalp of a composition consisting, in a physiologically acceptable medium, of an effective quantity of at least one precursor of densification chosen from among the compounds comprising at least one aromatic cycle having at least two hydroxyl groups borne by two consecutive carbon atoms of the aromatic cycle and an effective quantity of a catalytic system comprising one first constituent chosen from among the salts and oxides of Mn(II) and/or Zn(II) and mixtures thereof and a second constituent chosen from among the alkaline hydrogenocarbonates, the alkaline-earth hydrogenocarbonates and mixtures thereof.

Abstract: The invention relates to a process for improving the stability with respect to UV radiation of a photosensitive sunscreen agent, comprising the incorporation of said screening agent in a material prepared by the sol-gel route from at least one silicon alkoxide and from at least one surfactant. It is also targeted at a photostable material which comprises the combination of a photosensitive sunscreen agent and of a photostabilizing material prepared by the sol-gel route including at least one silicon alkoxide and at least one nonionic surfactant and at a cosmetic and/or dermatological composition comprising, in a cosmetically and/or dermatologically acceptable vehicle, an effective amount of a photostable material. This cosmetic and/or dermatological composition is intended mainly for protecting the skin and/or keratinous substances against ultraviolet radiation.

Abstract: The invention concerns a cosmetic or dermatological composition designed for for forming a film on a keratin substrate, in cross-linked hybrid material. Said composition is of the sol/gel type and is obtained by mixing: (a) at least an organometallic compound; (b) at least a functionalised organic polymer or said polymer precursor, or at least a functionalised silicone polymer or said polymer precursor, the precursor being different from (a); (c) a sufficient amount of water for hydrolysing the organometallic compound: and (d) optionally at least an alcohol; said film being non-reversible.
