Dermatologische Verträglichkeit von UV-Filtern, Duftstoffen und Konservierungsmitteln in Sonnenschutzpräparaten

Active sunscreens constituents are of two basic types: chemical agents that absorb ultraviolet radiation (UVR) und micropigments that act as physical barrier to UVR. Whereas micronized zinc oxide and titanium dioxide are well tolerated, UV absorbers can elicit allergic and photoallergic contact dermatitis. As photopatch testing is necessary to detect photoallergic reactions to UV filters and occasionally to perfume components, this important diagnostic tool is presented. Like many other cosmetics for skin care, sunscreen products can in addition contain perfume components, preservatives and emulsifiers that may cause allergic contact dermatitis. Now, that complete ingredient labeling according to INCI has become mandatory in the EU, the patient can avoid the (photo)allergenic ingredient in cosmetics provided he knows the INCI designation. Special sunscreen products for sensitive und photosensitive individuals are presented.
