Abstract: A method of treating skin or hair for promoting pigmentation wherein a xanthine component, in an amount effective to promote pigmentation, is incorporated in liposomes or hydrated lipidic lamellar phases.

Abstract: The invention relates to the use of an extract of Cyperus, in particular Cyperus rotundus L. for the preparation of a cosmetic or pharmaceutical composition, especially dermatological composition, intended for promoting the pigmentation of the skin or hair and/or for treating pigmentation disorders.

Abstract: The subject of the invention is the use of an extract of Stevia in combination with a salt, for masking the bitterness of bitter compounds in cosmetic or dermatological compositions. This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the compound permanently without changing the nature of the fragrance or the colour of the composition.

Abstract: A composition includes from 40 to 80% by weight of at least one non-volatile hydrogenated polyalkylene oil; from 10 to 50% by weight of at least one tertiary-amide-terminated polyamide (ATPA) polymer; and further at least one fatty acid ester having at least one free hydroxyl group, and preferably a hydroxystearate ester. The composition is translucid.

Abstract: A simarouba extract is used to produce a cosmetic or pharmaceutical, and particularly dermatological, composition or a skin cell culture medium. The resulting compositions are also disclosed. The simarouba extract has a significant skin depigmentation activity and can enhance the protective function of the skin, particularly its water barrier function, as well as having a significant keratinocyte differentiation activity.

Abstract: A nanometric material includes nitrogen-doped titanium oxides, which is obtained by injection of a titanium oxide precursor in the liquid or gaseous form and of a gaseous nitrogenous compound into a laser pyrolysis reactor. The material is used as cosmetic agent for protecting against ultraviolet radiation, thereby improving protection against UV radiation and in particular against UV-A radiation.

Abstract: The subject of the invention is the use of a sweetener such as sucralose or an extract of Stevia, for masking the bitterness of hydrophilic organic UV-screening agents in cosmetic or dermatological compositions. The sweetener may advantageously be used in combination with a mint aroma or a salt, for example sodium chloride. This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the hydrophilic UV-screening agent without changing the nature of the fragrance or the colour of the composition.

Abstract: A simaba extract is used to produce a cosmetic or pharmaceutical, and particularly dermatological, composition or a skin cell culture medium. The resulting compositions are also disclosed. The simaba extract has a significant skin depigmentation activity and can enhance the protective function of the skin, particularly its water barrier function, as well as having a significant keratinocyte differentiation activity.

Abstract: The invention relates to the use of an aqueous composition comprising at least one surface-active agent in the form of bilayers and exhibiting a structure of sponge phase type as cosmetic composition or for the preparation of a cosmetic composition. It also relates to aqueous compositions, in particular lotions, in the sponge phase form including at least one cosmetic active agent or one cosmetic additive. It also relates to a method for the cosmetic care of the skin or superficial body growths, in particular for the purpose of moisturizing them, and/or to a method intended to give fragrance to the skin or superficial body growths.

Abstract: The invention relates to an additive comprising at least 95 wt. % of a mixture consisting of at least one organic filter filtering UVA, at least one organic filter filtering UVB, and from 1 to 50 wt. % of at least one non-volatile oil that is a solvent for said filters. This composition is particularly useful as an agent for protecting the organoleptic properties of a transparent cosmetic composition, against UV radiation.

Abstract: The invention relates to the use of composite material which comprises nanoparticles of a least one metal derivative and at least one organic sunscreen agent which is chemically bound with said particles in a covalent manner in the form of an ultraviolet radiation protective agent containing the inventive composite material. Cosmetic ultraviolet radiation protective compositions comprises said mixture are also disclosed.

Abstract: The invention relates to a cosmetic composition for making up the skin, lips or superficial body growths, comprising a cosmetic base, at least one colored inorganic pigment [A] in an amount sufficient to define a first color of said composition in its body, and at least one pigment [B] chosen from organic dye lakes, the color of which is different from that of the pigment [A], in an amount sufficient to define a second color, radically different from said first color, which is revealed after the application of said composition on the lips, skin or superficial body growths.

Abstract: The invention relates to an oil-in-water emulsion for making up or caring for the lips. This emulsion contains a high proportion of glossy oils and is very fluid while remaining stable. This emulsion contains from 35% to 60% by weight of a mixture of oils, at least 25% by weight of water and from 0.01% to 20% of coloring material, everything being stabilized by the combination of a first polyethylene glycol ether of stearyl alcohol comprising from 2 to 5 oxyethylene units, a second polyethylene glycol ether of stearyl alcohol comprising from 15 to 25 oxyethylene units, and of a copolymer of acrylamido-2-methylpropane sulfonate and of hydroxyethyl acrylate.

Abstract: The present invention relates to a method of cosmetic treatment for combating the effects of skin ageing and to novel cosmetic compositions which are particularly suitable for carrying it out. According to the invention, at least one agent for promoting the adhesion of the keratinocytes of the epidermal baseal layer to the dermo-epidermal junction, especially to the collagen IV of said junction, such as, in particular, a divalent metal salt or complex, preferably magnesium aspartate or magnesium chloride, is used, optionally in association with a stimulant of collagen IV synthesis and/or a stimulant of collagen VII synthesis. The application is for the preparation of cosmetic compositions with anti-wrinkle activity.

Abstract: The present invention relates to a mixture, having a skin-tightening effect, which is made up of: 10 to 80% by Weight of a polysaccharide, preferably of an alginate, having a molecular weight of less than 600,000 Daltons, preferably less than 400,000 Daltons and more preferably less than 200,000 Daltons, 15 to 75% by weight of a polyhydroxylated agent selected from sugars and their derivatives, particularly sugar esters and sugar, ethers, preferably sorbitol, 3 to 15% by Weight of polyvinyl alcohol) or polyvinylpyrrolidone, and 0 to 25% by weight of cellulose or of a derivative of cellulose, such as carboxymethylcellulose or hydroxymethylcellulose. The present invention also relates to cosmetic compositions which contain this mixture. These cosmetic compositions enable a mechanical smoothing of the surface of the skin to be obtained progressively with great comfort of use and enables a good fixing of make-up products.
