Abstract: Cosmetic composition comprising fibers for topical application to the skin, the scalp and/or the hair protect keratinous materials against the harmful effects of pollution. The fibers have a length (L) ranging from 1 &mgr;m to 10 mm and a cross section within a circle having a diameter (D) ranging from 1 nm to 100 &mgr;m. In particular, the fibers may be polyamide fibers.

Abstract: The present application relates to the use of fibers in a skincare composition or a make-up composition for the skin, to make the complexion matte, smooth and/or uniform, and/or to fade out skin relief defects. The fibers are in particular polyamide fibers having a length of from 1 &mgr;m to 10 mm and a shape factor of from 5 to 150. The composition used gives the skin a covering index of greater than 0.1 and preferably greater than 0.13. The invention also relates to a cosmetic treatment process for fading the complexion matte, smooth and/or uniform, and/or for fading out microreliefs, wrinkles, fine lines and pores in the skin, comprising the application to the skin of fibers in a cosmetic composition.

Abstract: A composition in the form of a water/oil/water triple emulsion comprising an outer aqueous phase and an oily phase constituting, with an inner aqueous phase, a W/O primary emulsion, the outer aqueous phase comprising, in combination, an emulsifying copolymer of carboxylic acid with a fatty chain, and a crosslinked poly(acrylamidomethylpropane-sulfonic acid). The emulsion remains stable, even in the presence of an acidic active agent, and is particularly appropriate as vehicle for water-sensitive and/or oxygen-sensitive active agents, in particular in a cosmetic or dermatological composition. The active agent can be, in particular, a vitamin, such as ascorbic acid or retinol, an enzyme and an .alpha.- or .beta.-hydroxy acid. The emulsion obtained can constitute, in particular, a composition for cleaning and/or treating and/or protecting the skin and/or mucous membranes and/or keratinous fibers.
