Abstract: The present invention relates to a fermented extract of Longoza seeds, as well as to the preparation method thereof and to cosmetic compositions containing same. The fermented extract of Longoza seeds can in particular be used as an active ingredient to promote and/or stimulate epidermal renewal, desquamation of the skin, vitality of the skin cells, and/or cohesion of the skin cells, and/or to prevent and/or reduce the signs of skin ageing, in particular loss of firmness, loss of elasticity, loss of density, appearance of wrinkles and/or fine lines, dryness of the skin, alteration of the skin's barrier function, alteration of the skin's suppleness and/or alteration of the homogeneity or radiance of the complexion.

Abstract: The present invention relates to a cosmetic composition. This composition is characterized in that it comprises, as active ingredient, a green extract of seeds of the Aframomum angustifolium or longoza plant, obtained by extraction with a polar solvent of polyol, in particular a glycol, optionally in a cosmetically acceptable excipient. This cosmetic composition has a good anti-aging effect.

Abstract: The present invention relates to a synergistic extract of Palmaria palmata and of jasmine flower heads, obtained after aqueous extraction of Palmaria palmata, in which maceration of the jasmine flower heads is then carried out, the ratio of the dry weight of Palmaria palmata to the dry weight of the flower heads being between 40/60 and 95/5. The present invention also relates to a method for obtaining said synergistic extract and cosmetic compositions comprising said extract as an active agent. The invention finally relates to the cosmetic use of said composition for combating the signs of aging and for improving the elasticity of the skin, by favoring maintenance of the “stem” character of the adult dermal stem cells (SKPs).
