The invention relates to a cosmetic composition. This cosmetic composition comprises an extract of, 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.

Cosmetic composition containing an adenium obesum extract, use thereof and method for cosmetic care including the use thereof

A cosmetic composition includes as active agents, a first active agent consisting of an amber extract, and at least one other cosmetically active agent selected from the group consisting of extracts of, extracts of, magnesium aspartate, peptides acting on muscle contraction, particularly acetyl hexapeptide 3, peptides and their derivatives grafted with a fatty acid, particularly a Cfatty acid, promoting collagen synthesis, particularly palmitoyl oligopeptide pentapeptide 3 or palmitoyl tetrapeptide 7, soy flour hydrolyzates and plant glycolipids, particularly cereal glycosphingolipids and more particularly wheat glycosphingolipids. An amber extract also may be used as a cosmetic agent acting on the dermal supporting proteins and/or the enzymatic systems that degrade the dermal proteins and/or the glycan-type essential components of the extracellular matrix, particularly proteoglycans, for improving the essential biomechanical properties of the skin, namely firmness and elasticity, in the preparation of a cosmetic composition.

Cosmetic composition containing an amber extract

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.

Cosmetic treatment method for fighting against skin ageing effects

The invention relates to an extract of the plantcontaining at least one ecdysteroid and at least one iridoid and obtainable by extraction of at least part of said plant by means of a solvent or solvent mixture consisting of 0 to 60% by weight of water, the remainder of said solvent or solvent mixture consisting of at least one Cto Calcohol and/or acetone and/or butylene glycol and/or propylene glycol, and very particularly to an extract containing one part by weight of ecdysteroids to 2 to 4 parts by weight of iridoids. The invention further relates to cosmetic uses of these extracts or associations containing one part by weight of ecdysteroids to 2 to 4 parts by weight of iridoids as cosmetic agents for improving the differentiation of keratinocytes, for regulating the water fluxes and the water absorption in the epidermis or for hydrating the epidermis. The invention further relates to a method of cosmetic skin treatment in which a cosmetically effective amount of the extracts or associations defined above is applied.
