Cosmetic composition contains three ultraviolet filters, i.e. a benzimidazole derivative (I), a 1,3,5-triazine derivative (II) and an organic UV-A filter (III). Cosmetic composition contains a benzimidazole derivative of formula (I), a 1,3,5-triazine derivative (II) and an organic UV-A filter (III): X = S, NH, NR<1> or O; R<1> = 1-20C alkyl, 2-20C alkenyl, 3-15C cycloalkyl, 6-12C aryl, (6-12C)aryl(1-6C)alkyl, 2-21C alkoxycarbonyl or 5-12C heteroaryl, all optionally substituted by 1-6C alkyl, 1-16C alkoxy, 6-12C aryloxy, NH2, OH, CONR<2>R<3>, COOR<4> or Si(OR<7>)3 or interrupted by ether bonds; R<2>, R<3> = H or 1-6C alkyl; R<4> = H, 1-16C alkyl, 6-12C aryl or CH(R<6>)CH2(OCH(R<6>)CH2)nOR<5>; R<5> = 1-4C alkyl; R<6> = H or Me; R<7> = 1-4C alkyl; n = 0-4; R<8>-R<15> = H, NH2, NO2 or R<1>.
