EU Prohibits Gel Nail Ingredient After Animal Studies Reveal Reproductive Risks

European regulators have moved to prohibit trimethylbenzoyl diphenylphosphine oxide (TPO), a photoinitiator used in some gel nail polishes, citing evidence of reproductive toxicity from animal studies. TPO enables gel polishes to cure under UV or LED lights. The ban covers the European Union; the substance remains permitted for use in the United States at this time. Experts at The George Washington University are available to discuss what the decision means for consumers, potential health implications, and whether gel manicures remain safe.

Leonardo Tjahjono is an assistant professor of dermatology at the same school, with a clinical focus on cosmetic dermatology. -GW- MEDIA CONTACT Register for reporter access to contact details
