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 more specifically to a cosmetic treatment method intended in particular to improve the appearance of the skin and/or hair comprising the simultaneous and/or sequential administration: In particular, the said light radiation exhibits at least one predominant wavelength which activates cytochrome C oxidase ranging from 550 to 1000 nm, in particular from 550 to 800 nm, preferably from 620 to 700 nm and more preferably still from 640 to 680 nm and is preferably used at a dose ranging from 0.01 to 200 J/cm, preferably from 0.1 to 30 J/cm, more preferably from 1 to 30 J/cm, indeed even from 5 to 30 J/cm. The invention also relates to a composition comprising at least one cytochrome C oxidase substrate and/or one agent which increases the expression of the said substrate and at least one compound emitting and/or filtering, in particular under exposure to light, a light radiation exhibiting at least one predominant wavelength which activates cytochrome C oxidase, and to a kit comprising at least one composition comprising at least one cytochrome C oxidase substrate and/or one agent which increases the expression of the said substrate and one device and/or one compound emitting/filtering a light radiation exhibiting at least one predominant wavelength which activates cytochrome C oxidase.

Combination of a light ray with a cytochrome C oxidase substrate particularly for improving the appearance of the skin and/or hair

The present invention relates to the use of a source of green light for activating L-amino acid oxidase in the presence of at least one substrate of this enzyme in order to stimulate the energy metabolism of the cells of the skin, to stimulate their replacement and thus to improve the appearance of the skin and hair, in particular to prevent and/or treat cutaneous signs of ageing of the skin and hair.

Use of green light to activate L-amino acid oxidase

The present invention relates to the cosmetic use by external topical route of steviol, of a steviol glycoside derivative or of one of their isomers to stimulate, restore or regulate the metabolism of the cells of the skin.

Cosmetic use of steviol, of a steviol glycoside derivative or of one of their isomers to stimulate, restore or regulate the metabolism of the cells of the skin and semimucus membranes

The present invention relates to the use, especially the cosmetic use, of at least one monosaccharide chosen from mannose, rhamnose and a mixture thereof, for reducing or preventing the signs of ageing of the skin or its integuments. The present invention also relates to a cosmetic composition and a device containing it.

Use of monosaccharides and composition therefor

Composition containing a combination of at least one monosaccharide chosen from mannose, rhamnose and a mixture thereof, and of at least one additional compound chosen from ascorbic acid, an analogue thereof and a mixture thereof. The present invention also relates to the use of such a composition for combating the signs of ageing, and also to a device containing the composition.

Combination of monosaccharides with ascorbic acid and use thereof

The invention relates to the combination of a light ray with a cytochrome C oxidase substrate for improving the appearance of the skin and/or the hair.

Composition, especially a cosmetic and/or dermatological composition, containing, in a physiologically acceptable medium, at least one of mannose, and rhamnose and at least one additional compound chosen from C-glycosides and C-glycoside derivatives. Use of such a composition, and also a device containing it.
