Graphical abstract Unlabelled Image Highlights • EHMC is one of the most widely used organic UV filters. • Trans -EHMC exposed to UV radiation, including sunlight, isomerizes to cis -EHMC. • cis -EHMC and trans -EHMC differ in genotoxicity response in bacteria and human cells. • Toxicokinetics and -dynamics of each isomer need to be tested separately to predict their risks. • These finding are presented to competent authorities to re-evaluate the use of EHMC.
