Disclosed is the use of an insoluble or sparingly soluble micronized substance class which is not a cosmetic UV absorber and which is dispersed in the oil- or water-phase of a cosmetic or dermatological composition for the enhancement of light protecting action of this cosmetic or dermatological composition comprising at least one cosmetic UV filter which is soluble in the water- or oil-phase. The cosmetic preparation according to the invention shows a remarkable increase in SPF.

Use of benzotriazole derivatives for photostabilisation

Disclosed is the use of an aqueous dispersion comprising (a) a micronized sparingly soluble organic compound which has a UV-Vis spectrum with a maximum from 380 to 420 nm; and (b) an anionic dispersing agent for protecting the human skin from browning and skin aging.
