Provided are cosmetic or dermatological compositions for topical use, in particular for the photoprotection of the skin and/or hair, characterized in that they comprise, in a cosmetically acceptable vehicle, at least: (a) particulates of one insoluble organic UV-screening agent having a particle size ranging from 10 nanometer to 5 micrometer, and (b) one specific amino-substituted 2-hydroxybenzophenone derivative as the second shielding agent. The combination of the two UV-screening compounds results in a synergistic activity to confer solar protection factor. The invention also relates to the use of the composition for the photoprotection of the skin and/or hair against the deleterious effects of ultraviolet radiation. |
