The UV-stability of the UV-photoprotecting dibenzoylmethane compounds is conspicuously enhanced, as is the UV-stability of cosmetic/dermatological sunscreen compositions comprised thereof, by formulating such dibenzoylmethane compounds with an effective UV-photostabilizing amount of at least one micronized insoluble organic UV-screening agent, the mean particle size of said micronized particles ranging from 0.01 to 2 .mu.m.

A UV-estabilidade dos compostos uV-photoprotecting-photoprotecting do dibenzoylmethane é realçada conspìcuamente, como é a UV-estabilidade de cosmetic/dermatological sunscreen as composições compreendidas disso, formulando tais compostos do dibenzoylmethane com uma quantidade uV-photostabilizing-photostabilizing eficaz ao menos de um agente orgânico insoluble micronized da UV-seleção, o tamanho de partícula médio das partículas micronized ditas que variam de 0.01 ao mu.m 2.
