摘要:
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.
