A photostable cosmetic filter composition for protecting human skin against UV radiation at wavelengths between 280 and 380 nm comprises, in a cosmetically acceptable support medium containing at least one oily phase, 1 to 3% by weight of a dibenzoylmethane derivative and at least 1% by weight of a substituted dialkylbenzalmalonate having formula I: <IMAGE> (I) R1 and R3 may be identical or different and represent H or a straight- or branched-chain C1-C8 alkoxy radical. R2 and R4 represent a straight- or branched-chain C1-C8 alkyl radical. The molar ratio of compound (I) to the dibenzoylmethane derivative is greater than or equal to 0.6. |
