As a veteran beauty editor, I know this much: Europe is far stricter than the U.S. when it comes to cosmetic (and even food) ingredients. The European Union (EU) takes a precautionary stance, while the U.S. often reacts only after issues arise. So when I learned that, as of September 1, Europe officially banned a key ingredient found in many gel nail polishes, I wasted no time speed-dialing my trusted dermatologist for her expert take.
Of course I care about my health, but having a chip-free, long-lasting manicure is also a hard beauty treatment to give up. Do we need to?
What Gel Nail Polish Ingredient Is Banned in Europe?
Starting September 1, the European Union banned TPO (trimethylbenzoyl diphenylphosphine oxide), a chemical photoinitiator (a light-sensitive compound that absorbs light energy and converts it into chemical energy) that helps gel nail polish harden under UV or LED light. In other words, it’s the ingredient that gives gel manicures their quick-dry power and that signature glass-like shine. The reason for the ban? TPO is classified as a CMR 1B substance—meaning it’s considered carcinogenic, mutagenic, or toxic to reproduction. Yikes.
Do You Need to Stop Getting Gel Nails?
When it comes to beauty treatments, it’s always wise to do your homework, trust your instincts, and check in with your doctor or dermatologist. The EU is banning this particular ingredient out of caution, though so far, there haven’t been any large-scale human studies showing definitive harm. The good news for gel manicure lovers is that you don’t have to give up your favorite look—many polishes are now made without this ingredient. At the salon, simply ask for a TPO-free formula; options include brands like Manucurist, Aprés Nails, and OPI’s Intelli-Gel system.
