Abstract: A device for cosmetic treatment of human keratin materials, including: a handpiece that includes an electrical assembly, and an application member that is fixed to the handpiece and defines an application surface, the application surface having an area of between 50 and 200 mm2, or between 70 and 150 mm2, and the handpiece is configured to generate a thermal amplitude of greater than or equal to 5° C. between the keratin materials and the application surface for a duration of at least 5 minutes, or a thermal amplitude of greater than or equal to 20° C. for a duration of at least 5 minutes.

Abstract: The present invention relates to the cosmetic use of a cold atmospheric plasma for preventing and/or treating aesthetis disorders of the healthy scalp.

Abstract: A device for treating human keratinous materials includes an electrical appliance comprising a handpiece and a reader, and an applicator suitable for being removably fastened on the handpiece. The applicator includes a solid cosmetic or dermatological composition for applying to the keratinous materials, and/or an applicator element including fibers and/or cells suitable for enabling a cosmetic or dermatological composition to be applied on keratinous materials. The applicator also includes an encoder for encoding information arranged to be read by the reader. The operation of the handpiece depends on the information read.

Abstract: The present invention relates to kits for formulating a cosmetic product, containing an aqueous composition and at least one water-soluble anhydrous film, the aqueous composition and the film(s) being mixed together extemporaneously to form the cosmetic product.

Abstract: The present invention provides an assembly comprising: a substrate comprising biocellulose; a powdered cosmetic composition that is at least partially hydrosoluble, to be brought into contact with the substrate.

Abstract: An applicator for the application of a product, for example a cosmetic or dermatological product, including a reservoir of which a first side is attached to a finger or mounted to a finger to face the finger. An applicator portion is arranged on a second side of the reservoir opposite the first, and the applicator portion is isolated from the reservoir at least before first use of the applicator. The applicator device further includes a device to establish communication between the reservoir and the applicator portion, for example, in response to an operating action at least during the first use of the applicator.

Abstract: Disclosed herein is a transungual device comprising at least one active agent chosen from extracts of a non-fruiting, non-photosynthetic filamentous bacterium, dialkyl sulphones, and mixtures thereof. Also disclosed herein is a method for the cosmetic treatment of nails comprising applying the transungual device to the nails.

Abstract: Disclosed herein is a method for shaving the skin, comprising (1) forming at the time of use a shaving composition by bringing at least one anhydrous film into contact with a solvent, for example an aqueous composition, (2) applying the composition thus formed to the surface of the skin to be shaved, and (3) shaving hairs using a razor. Also disclosed herein is a shaving kit comprising (a) at least one anhydrous film which is soluble or dispersible in a solvent, (b) at least one razor, such as a disposable razor, and/or (c) a means for spreading a shaving composition. The kit may further comprise the solvent intended to be mixed at the time of use with the anhydrous film or an aftershave composition.

Abstract: The invention relates to conjugates of lipids and basic, membrane disturbing peptides, particularly compounds of the formula(R--CONH).sub.n --R.sup.3 (I)and(R--S--S).sub.n --R.sup.3 (II)wherein R is the hydrocarbyl moiety of a straight-chain or branched-chain, saturated or unsaturated aliphatic carboxylic acid, or a phospholipid moiety having a free valence bond; R.sup.3 is a basic membrane disturbing peptide having a free valence bond at one or two carbon atom(s); and n is 1 or 2. These conjugates can be used as a vector for transfecting a cell with a polynucleotide or any other anionic macromolecule.

Abstract: Compounds of the formulaR.sup.1 --NH--A Iwherein R.sup.1 is an acyl moiety of a C.sub.12-40 aliphatic carboxylic acid, A is the residue of a oligopeptide devoid of one amino group, and --NH--A contains at least one positively charged amino acid, or derivatives thereof can be used for transferring anionic macromolecules into cells.
