Abstract: The present invention relates to a method for the cosmetic treatment of a keratin material comprising at least the steps of: (a) having available a lyophilizate containing at least one live or inactivated, physiologically acceptable microorganism, one of its metabolites or one of its fractions and at least one surfactant with an HLB greater than or equal to 12, (b) having available a physiologically acceptable medium, separate from the said lyophilizate, (c) bringing the said lyophilizate extemporaneously into contact with the said medium under conditions favourable for the solubilization and/or dispersion of the said lyophilizate in the said medium, and (d) bringing the mixture obtained in the preceding step into contact with the said keratin material. It further relates to a lyophilizate as defined above.

Abstract: The present invention relates to novel compounds of formula (1) and also to cosmetic compositions containing them and to the cosmetic uses thereof, in particular for protecting the skin against UV-induced oxidative stress.

Abstract: Dithiolane compounds having the structural formula (I): are useful for reinforcing and/or preserving the natural antioxidant protection of the skin against oxidative stress caused, especially, by UV radiation, e.g., by increasing the level of intracellular glutathione.

Abstract: The present invention relates to a composition, especially a cosmetic and/or dermatological composition, containing, in a physiologically acceptable medium, a combination of at least one monosaccharide chosen from mannose, rhamnose and a mixture thereof, and of at least one antioxidant. The present invention also relates to the use of such a composition.

Abstract: Cosmetic/sunscreen compositions contain a combination of at least one dibenzoylmethane sunscreen compound and a photostabilizing amount of at least one dithiolane compound of formula (I) below:

Abstract: The present invention relates to novel compounds of formula (1) and also to cosmetic compositions containing them and to the cosmetic uses thereof, in particular for protecting the skin against UV-induced oxidative stress.

Abstract: Improvedly effective and photostable sunscreen compositions combine a dibenzoylmethane screening agent and a specific arylalkyl amide or ester compound of the following formulae (I), (II) or (III):

Abstract: A composition, suitable for topical application to the skin, containing at least one benzoisothiazolone of formula (I): Novel benzoisothiazolones of formula (I) and a method of caring for dry and/or mature skin.

Abstract: A composition, suitable for topical application to the skin, containing at least one benzoisothiazolone of formula (I): Novel benzoisothiazolones of formula (I) and a method of caring for dry and/or mature skin.

Abstract: The present invention relates to novel heterocyclic derivatives of 2-oxothiazolidine-4-carboxylic acid, to a process for synthesizing them and to compositions containing them. The invention also relates to the use of at least one heterocyclic derivative of 2-oxathiazolidine-4-carboxylic acid in a composition or for the manufacture of a composition, the said derivative or the said composition being intended to induce active photoprotection of the skin, advantageously to prepare the skin to receive sunlight and/or to protect the skin and other epidermal growths during or after exposure to UV. Another subject of the invention also relates to a cosmetic process for treating the skin by oral administration or topical administration to the skin of a cosmetic composition as defined above.
