Abstract: The present invention concerns a composition for topical application to keratinous material, in particular the skin and/or lips, comprising, in a physiologically acceptable medium, at least one Lactobacillus rhamnosus extract (CNCM I-5313), one of its fractions and/or one of its metabolites and at least one excipient chosen from solvents other than water, UV filters, surfactants, gelling agents, thickeners, fillers, dyes, film-forming polymers, perfumes and the mixtures of same; and the uses thereof, in particular for promoting and/or improving the skin barrier function.

Abstract: The present invention relates to a cosmetic composition, which comprises a combination of at least two osmolytes chosen from the group comprising taurine or a derivative thereof, inositol, betaine and trehalose. This composition is intended for restoring, maintaining or reinforcing the moisturization of the skin and/or for protecting it against different types of stress and/or for preventing or retarding the appearance of the signs of aging of the skin, or for attenuating the effects thereof, or alternatively for promoting cell or tissue longevity.

Abstract: The present inventor relates to an electrochemical device for measuring the redox state of the skin, comprising at least one working electrode, such as a microelectrode, a counter electrode, and a reference electrode, said electrodes all being fixed into a single support intended to allow each of said electrodes to be simultaneously brought into contact with the surface of the skin to be tested, the electrodes being connected, on the one hand, to a means for imposing a defined voltage between the working electrode and the reference electrode, such as a potentiostat, and, or the other hand, to a device for measuring the intensity of the current generated at the working electrode by the detection of redox species. The invention also related to a method of measuring the redox state of the skin.

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 basal 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 invention relates to a concentrated, clear, liquid detergent composition capable of being poured and capable of being diluted with water to give a viscous diluted composition. This concentrated composition contains at least one anionic surface agent; a regulator of the viscosity of the diluted composition, consisting of at least one surface agent chosen from the group consisting of nonionic, amphoteric and zwitterionic surface agents, which is combined with at least one acid or its salt in such quantity that it is dissolved in the concentrated composition; the surface agent and the acid or the salt being chosen so that the viscosity of the diluted composition decreases, or increases and then decreases, when the quantity of acid or of its salt increases, for given surface agents, and water.
