Abstract: The present invention relates to a method for protecting the skin against UV rays, using two cosmetic compositions for protecting against UV rays, the sun protection indices of which are different from each other, this method consisting in applying to the skin, before or during exposure to sunlight, a first composition having a certain sun protection index, and then in applying, during exposure to sunlight, onto the residual deposit of the first composition, the second cosmetic composition having a sun protection index lower than that of the first composition. This method advantageously makes it possible to not reapply the first composition, but to use a second product that is much more pleasant to use, while at the same time obtaining the level of protection afforded by the deposit of the initial first composition.

Abstract: The invention relates to an additive comprising at least 95 wt. % of a mixture consisting of at least one organic filter filtering UVA, at least one organic filter filtering UVB, and from 1 to 50 wt. % of at least one non-volatile oil that is a solvent for said filters. This composition is particularly useful as an agent for protecting the organoleptic properties of a transparent cosmetic composition, against UV radiation.

Abstract: The invention relates to a perfuming solution comprising a volatile alcohol, a perfume and a mixture for stabilizing said perfume consisting of at least one UV filter selected from the derivatives of cinnamate, at least one UV filter selected from the derivatives of dibenzoylmethane, and at least one non-volatile oil that is soluble in said alcohol and is a solvent for said filters, the stabilizing mixture being in sufficient amount to protect the perfuming solution from degradation by UV radiation.

Abstract: The invention relates to a method for preventing or slowing down the appearance of the effects of skin ageing, in particular for slowing down the formation of wrinkles on the face, and reducing or smoothing out the wrinkles already formed, using a tocopheryl phosphate in liposomes.

Abstract: The subject of the invention is the use of a sweetener such as sucralose or an extract of Stevia, for masking the bitterness of hydrophilic organic UV-screening agents in cosmetic or dermatological compositions. The sweetener may advantageously be used in combination with a mint aroma or a salt, for example sodium chloride. This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the hydrophilic UV-screening agent without changing the nature of the fragrance or the colour of the composition.

Abstract: The subject of the invention is the use of an extract of Stevia in combination with a salt, for masking the bitterness of bitter compounds in cosmetic or dermatological compositions. This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the compound permanently without changing the nature of the fragrance or the colour of the composition.

Abstract: The invention relates to a perfuming solution comprising a volatile alcohol, a perfume and a mixture for stabilizing said perfume consisting of at least one UV filter selected from the derivatives of cinnamate, at least one UV filter selected from the derivatives of dibenzoylmethane, and at least one non-volatile oil that is soluble in said alcohol and is a solvent for said filters, the stabilizing mixture being in sufficient amount to protect the perfuming solution from degradation by UV radiation.

Abstract: The invention is directed to liposomes comprising at least one wall formed by a bilayer of amphiphilic lipids and containing an oxazolidin-2-one compound substituted in the 4-position, of formula (I): wherein the R represents a linear or branched, saturated or unsaturated hydrocarbon-based group containing from 4 to 30 carbon atoms. These liposomes may be used in the form of an aqueous dispersion in cosmetic or dermatological compositions comprising said dispersion; and at least one cosmetically or dermatologically acceptable excipient.

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.
