Abstract: There are provided compositions which include a retinoid and preferably retinal; a dermatologically active acid; and a volatile base, such as ammonium hydroxide. Another embodiment of the invention includes compositions comprising a retinoid and preferably retinal; a dermatologically active acid; a volatile base; and a second neutralizing agent. There are also provided compositions which include a retinoid, a neutralized ammonium salt of a dermatologically active acid, and optionally a neutralized salt, other than ammonium salt, of an acid. Further provided are methods for reducing fine lines, wrinkles, skin roughness, and pore size and for increasing the clarity of a skin surface, cellular turnover, skin radiance, skin smoothness, skin permeation or collagen synthesis in a mammal in need thereof. Compositions as described above are administered topically to the skin of the animal.

Abstract: The present invention relates to cosmetic compositions having good physical and chemical stability, comprising a retinoid and at least one coloured pigment selected from metal oxides, the said pigments being treated (or coated) with one or more hydrophilic or lipophilic components.

Abstract: The present invention relates to new cosmetic compositions for topical use which are intended more particularly for the photoprotection of the skin and/or hair against ultraviolet radiation and to their use in the abovementioned cosmetic application. Still more precisely, it relates to antisun compositions which comprise, in a cosmetically acceptable vehicle, an association of a specific screening agent, chosen from dibenzoylmethane derivatives, with at least one inorganic titanium oxide nanopigment treated with silanes and/or silicones.

Abstract: Topically applicable sunscreen/cosmetic compositions well suited for enhanced photoprotection of human skin and/or hair against the damaging effects of UV-A and UV-B irradiation, particularly solar radiation, comprise (i) a photoprotecting effective amount of 2,4,6-tris[p-((2'-ethylhexyl)oxycarbonyl)anilino]-1,3,5-triazine and (ii) at least one homomenthyl and/or octyl salicylate solvent for the triazine sunscreen compound (i), in a cosmetically acceptable vehicle, diluent or carrier therefor.

Abstract: Topically applicable sunscreen/cosmetic compositions well suited for enhanced photoprotection of human skin and/or hair against the damaging effects of UV-A and UV-B irradiation, particularly solar radiation, comprise (i) a photoprotecting effective amount of at least one of the sunscreen compounds 4-methylbenzylidenecamphor and/or 4-(tert-butyl)-4'-methoxydibenzoylmethane and (ii) at least one homomenthyl and/or octyl salicylate sunscreen solvent, in an amount sufficient to substantially completely dissolve the total amount of the at least one sunscreen compound (i), in a cosmetically acceptable vehicle, diluent or carrier therefore.
