The invention relates to a cosmetic composition comprising at least one cosmetically acceptable excipient and from 0.01 to 1% by weight, preferably from 0.05 to 0.6%, and more preferably from 0.1 to 0.3% by weight of the combination of an extract of the brown alga, of ahydrolysate and of ascorbic acid or one of its esters, the percentage being expressed by dry weight. The combination of active agents of the invention for which a synergistic effect with regard to the synthesis of the procollagen I has been shown also produces an advantageous effect with regard to other markers of aging.

Cosmetic composition containing a brown alga extract, a yeast extract and ascorbic acid

An extract of the seeds of theplant is obtained by bringing into contact with at least one cosmetically acceptable nonpolar solvent, for example, CO, under supercritical conditions, or by mechanical pressing. This disclosure also relates to a cosmetic or dermatological composition comprising said extract. This disclosure also relates to a cosmetic or dermatological care method comprising the application of said composition for preventing or delaying the appearance of the signs of skin aging, modulating the reactivity of sensitive skin, or maintaining the barrier function of the skin.

[object Object]

The present invention relates to cosmetic or dermatological compositions comprising a combination of a cannabis essential oil substantially free of cannabinoids and a helichrysum essential oil, and to their uses thereof, particularly for the care of sensitive or sensitized skin.

Cosmetic or dermatological compositions comprising a mixture of essential oils, and its uses thereof, particularly for the care of sensitive or sensitized skin

An extract is from the plant. The sap from the plantor of an extract of that plant is used as a hydrating active agent in a cosmetic composition, to restore, maintain or reinforce the hydration state of the skin.

The present inventor relates to an electrochemical device for measuring the redox state of the skin, comprising at least one working electrode, such as a microelectrode, a counter electrode, and a reference electrode, said electrodes all being fixed into a single support intended to allow each of said electrodes to be simultaneously brought into contact with the surface of the skin to be tested, the electrodes being connected, on the one hand, to a means for imposing a defined voltage between the working electrode and the reference electrode, such as a potentiostat, and, or the other hand, to a device for measuring the intensity of the current generated at the working electrode by the detection of redox species. The invention also related to a method of measuring the redox state of the skin.

Electrochemical device and method for measuring the redox state of the skin

Cosmetic compositions with anti-free radical activity have been developed. Such compositions preferably contain an association of at least the following three substances with anti-free radical activity: an extract of emblica, idebenone and N-acetylcysteine.

Cosmetic composition with anti-free radical activity

Cosmetic compositions with anti-free radical activity have been developed. Such compositions preferably contain an association of at least the following three substances with anti-free radical activity: idebenone; N-acetylcysteine, and alpha-tocotrienol or an ester thereof with a C-Corganic acid.

The present invention relates to the use, in a cosmetic composition, of an extract of at least one part of an orchid of the species, as an agent for maintaining or restoring the hydration state of the skin, said composition also containing a cosmetically acceptable excipient. This skin hydrating effect is obtained in particular by stimulating the expression of aquaporin 3 and of the LEKTI protein. The invention also relates to a cosmetic skincare method for the purpose of improving the hydration state of said skin.

A cosmetic composition has an association of at least three of the following substances with anti-free radical activity, selected from: in which:R=a linear or branched, saturated or unsaturated C-Chydrocarbon chain; andR, Rand Rare identical or different and are a hydrogen atom or a methyl or methoxy radical,and its esters; The anti-free radical activity is greatly improved.

The invention relates to the use of L-2-thiohistidine, or a cosmetically acceptable salt or ester of its acid group, as a depigmenting agent in a cosmetic composition or for the preparation of a cosmetic composition. It further relates to a method of cosmetic care for toning down or eliminating pigment spots on the skin and/or lightening the complexion by the application of this cosmetic composition. The invention provides a highly depigmenting composition.

Use of L 2-thiohistidine or one of its derivatives as a depigmenting agent in cosmetics

The invention relates to the use, in a cosmetic composition or for the production of a cosmetic composition, of an extract of an exudate of the plant, said exudate being at least partially made up of the oleoresin of said plant. It relates most particularly to the use of this extract as a cosmetic agent for modifying the surface of the skin by giving it a smoother appearance through a reduction in the depth of the wrinkles and/or fine lines and/or by providing it with a re-plumping effect. It also relates to a cosmetic care method for modifying the surface of the skin by giving it a smoother appearance through a reduction in the depth of the wrinkles and fine lines and/or by providing it with a re-plumping effect, comprising the application, to the areas of the skin in question, of a cosmetic composition containing this extract.

The invention relates to a protecting and regenerating composition. This composition comprises an association of a first cosmetically active ingredient comprising a dried vine shoot extract, and a second cosmetically active ingredient comprising a component of the ectoine type. This composition makes it possible to affect anti-ageing cosmetic care and skin revitalization.

Protecting and regenerating composition

A cosmetic composition comprising, as active agent, an extract of biomass of the alga, the active agent being incorporated in a cosmetically acceptable vehicle compatible with topical application. This extract is advantageously an alcoholic or aqueous-alcoholic extract, called the first extract obtained by treating the biomass with a first alcoholic or aqueous-alcoholic solvent, and/or at least one fraction of the first extract, obtained by fractionating the first extract.

The invention relates to a cosmetic composition, characterized in that it contains, as active agent, an extract ofobtained by extraction with an extraction solvent selected from the group comprising alcohols and aqueous-alcoholic mixtures, in a cosmetically acceptable vehicle compatible with topical application. It further relates to a method of cosmetic treatment intended especially for soothing non-pathological skin manifestations of inflammatory origin and/or preventing and/or combating the effects of intrinsic and/or photoinduced ageing, comprising the application to the skin of a cosmetic composition of the invention.

The present invention relates to a cosmetic composition. This composition is characterized in that it comprises, as active ingredient, an extract of seeds of theorplant, optionally in a cosmetically acceptable excipient. This cosmetic composition exhibits a good anti-ageing activity.
