A method for treating human keratin fibers such as the hair is described and comprises the application to the keratin fibers of a dye composition comprising at least one silicone acrylic copolymer and at least one pigment, optionally the application of heat to the dyed keratin fibers using a heating tool and the application to the dyed keratin fibers of a makeup-removing composition comprising at least one hydrocarbon oil.

Method for treating keratin fibers using a composition comprising at least one silicone acrylic copolymer and at least one pigment

A method for treating human keratin fibers such as the hair is described and comprises the application to the keratin fibers of a dye composition comprising at least one cationic acrylic copolymer and at least one pigment, and the application to the dyed keratin fibers of a makeup-removing composition comprising at least one hydrocarbon oil.

Method for treating keratin fibers using a composition comprising at least one cationic acrylic copolymer and at least one pigment

The present invention relates to a composition, especially a cosmetic composition, particularly a photoprotective composition, comprising at least: &#x2014;photonic particles having an average size comprised from 0.5 &#x3bc;m to 100 &#x3bc;m and each including an arrangement that diffracts monodisperse nanoparticles or voids, the diffraction spectrum of this arrangement including a reflection peak of the first order in the range of wavelengths ranging from 250 nm to 1800 nm, preferably from 250 nm to 400 nm, &#x2014;at least one absorber, said absorber being a molecule having an absorption spectrum in the UV-near IR domain (100 nm-3000 nm) whose mass extinction coefficient &#x3b5;1% is greater than or equal to 160 g&#xb7;100 mL&#xb7;cm, and &#x2014;at least one surfactant.

Composition comprising photonic particles, at least one absorber and at least one surfactant

The present disclosure relates to cosmetic compositions and methods of using the cosmetic compositions to benefit the skin. The cosmetic compositions typically include: (a) resveratrol, polydatin, or a mixture thereof; (b) baicalin; (c) optionally, one or more solubilizers; and (d) a cosmetically acceptable carrier. The compositions provide multiple benefits to skin. For example, the compositions are particularly useful for providing anti-aging benefits to skin, for whitening the skin, and for improving skin's appears (e.g., radiance and firmness).

Photo-stabilized compositions and methods of use

Cosmetic method in which: a) a color is acquired from a region of the body of an individual, by using a device equipped with a color camera and by placing a color reference chart in the field of said camera during the acquisition; and b) using the device, and the color acquired in a), and optionally knowledge of the tanning pathways of various skin colors, at least one indication is delivered concerning skin type and/or at least one indication is delivered concerning at least one skin color obtainable by the individual via the pigmentation or depigmentation process and/or at least one indication is delivered concerning photoprotection and/or application or administration of a product intended to temporarily modify the color of the skin.

Method for delivering cosmetic advice

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.

Combination of monosaccharides with antioxidants and use thereof

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 favorable 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.

Extemporaneous care product based on a lyophilizate of microorganisms and surfactant(s) with an HLB greater than or equal to 12

A photoprotective composition, in particular a cosmetic composition, that includes particles of photonic material having a polymeric multilayer interference structure, where at least two layers of the structure contain an amphiphilic polymer.

Photoprotective compositions and films, and a preparation method

A cosmetic regime or regimen for depigmenting, lightening and/or bleaching keratin materials, especially the skin, entails topically applying thereon a cosmetic composition containing a dithiolane compound of formula (I): in which:

Depigmenting keratin materials utilizing dithiolane compounds

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: 

Cosmetic/sunscreen compositions containing dibenzoylmethane compounds and dithiolane compound photostabilizers therefor

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.

Administration of dithiolane compounds for photoprotecting the skin

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. 

Silane esters and amides of 2-oxothiazolidine-4-carboxylic acid, and cosmetic uses thereof

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.

Benzoisothiazolone compositions

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.
