Abstract: Cosmetic use of an effective amount of at least one lysate of at least one microorganism of the genus Bifidobacterium species and/or a fraction thereof, for preventing and/or treating a skin disorder in the case of sensitive skin.

Abstract: Cosmetic use of an effective amount of a lysate of at least one microorganism of the genus Bifidobacterium species and/or one of its fractions in treating and/or preventing dryness and/or associated disorders of a keratinous substance.

Abstract: A reconstructed epidermis/skin equivalent supplemented with at least one ceramide 7 and/or 5.5 compound, suited for reinforcing the barrier function of normal human epidermis and for improving the barrier function of dry skin and of reconstructed skin or skin equivalents, is prepared by introducing the at least one ceramide 7 and/or 5.5 compound into the culture medium of such reconstructed epidermis/skin equivalent and/or topically applying onto the face surface of such reconstructed epidermis/skin equivalent a composition which comprises lipid lamellar vesicles incorporating at least one ceramide 7 and/or 5.5 compound.

Abstract: The present invention relates to the use of at least one EcR receptor ligand in a cosmetic or dermatological preparation for maintaining cutaneous homeostasis. The present invention also relates to a cosmetic treatment process for maintaining cutaneous homeostasis, which consists in applying a composition according to the invention.

Abstract: Novel ceramide compounds, compositions containing them and the use of these compounds, in particular for strengthening the lipid barrier of the epidermis.

Abstract: Synergistic immixtures of ascorbic acid with at least one monosaccharide ester of ascorbic acid and/or at least one metal salt of phosphorylated ascorbic acid more effectively increase the synthesis of epidermal ceramides in human skin, especially types IV to VII ceramides, as well as improve the barrier function, moisture content and/or suppleness/surface appearance of the skin and which otherwise combat/prevent intrinsic aging thereof and are useful for the treatment of dermatitis.

Abstract: The invention concerns a composition comprising, in a physiologically acceptable medium, at least a ceramide precursor, the use of said compound in particular for reinforcing the lipid barrier of the epidermis and/or for improving the quality and properties of reconstructed epidermis, and a skin equivalent supplemented with said compound.

Abstract: The present invention relates to the use of DHEA and/or of its chemical and/or biological precursors and derivatives, in a cosmetic composition or for the manufacture of a dermatological composition for topical application to the skin, for preventing atrophy of the epidermis which is one of the characteristic signs of intrinsic and/or photoinduced skin ageing.
