UV-Strahlung und Pigmentierung: Arylhydrocarbonrezeptor – „a new kid on the block“

UV radiation is the most important modulator of skin pigmentation. In this article we report on novel studies which show that the aryl hydrocarbon receptor, which can be activated by UV-generated photoproducts, mediates a substantial part of UVB-induced skin pigmentation reaction. This newly discovered mechanism opens interesting possibilities for cosmetic and therapeutic treatment of pigment disorders.
