Abstract: The invention relates to a cosmetic composition. This cosmetic composition comprises an extract of Adenium obesum, and at least one cosmetically acceptable excipient. This composition can be used to strengthen the cutaneous barrier, to reinforce the cohesion of the dermal-epidermal junction, to prevent or delay the effects of skin aging, or else to provide a protective, corrective, restructuring, hydrating or moisturizing effect.

Abstract: A polyphenol-rich plant extract is used in combination with at least one hydrating or humectant agent, as cosmetic active agents in a cosmetic composition. The combination improves hydrating and antioxidant cosmetic care.

Abstract: The present invention relates to a novel use of an extract of common mallow for restoring, maintaining or reinforcing the state of moisturization of the skin; to a cosmetic composition containing it, and also to cosmetic care methods using said composition.

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.

Abstract: The invention relates to a cosmetic care method comprising the delivery of an effective amount of at least one cosmetically acceptable agent that activates or stimulates survivin expression in the stem cells of the basal layer of the epidermis. The invention makes it possible in particular to prevent or delay the appearance of the signs of skin aging or to treat them.

Abstract: The invention relates to a cosmetic composition of a tocopheryl phosphate, especially in its dl or d form, or in the form of a cosmetically acceptable salt or ester thereof, as a cosmetic agent for preventing or slowing down the appearance of the effects of skin ageing, in particular of photoageing of the skin, said tocopheryl phosphate being at least partially encapsulated in lipid vesicles, in particular liposomes. It relates most particularly to the use of alpha-tocopheryl phosphate. It also relates to cosmetic compositions containing a tocopheryl phosphate, in particular an alpha-tocopheryl phosphate, at least partially incorporated into lipid vesicles, in particular liposomes, these compositions being in particular in the form of a serum or of a stable emulsion. The invention also relates to a cosmetic skincare process.

Abstract: The invention relates to a composition in the form of an emulsion comprising a continuous aqueous phase and a dispersed fatty phase, characterized in that said aqueous phase contains liposomes in the presence of a non-ionic surfactant chosen from fatty alcohol polyethylene glycol ethers and fatty alcohol polypropylene glycol ethers, and mixtures thereof, and of at least one polysaccharide in water-soluble form. It also relates to a method for preparing this composition. It also relates to a stable dispersion of liposomes that can be used for the preparation of the aqueous phase of this composition.
