The Risks Behind That Perfect Gel Shine

Gel manicures have become one of the most popular beauty treatments in the U.S., prized for their durability and glossy finish that can last weeks without chipping. Unlike regular nail polish, gel polish is cured under ultraviolet (UV) light, creating a tough, long-lasting layer.

But recent moves in Europe have raised concerns: the EU banned trimethylbenzoyl diphenylphosphine oxide (TPO), a chemical widely used in gel polish, after animal studies linked it to fertility issues, organ damage, and developmental problems.

While those studies involved rodents exposed to high oral doses, experts say nail salon workers who handle gel products daily face greater risks, especially with constant UV exposure.

Dermatologists add that frequent gel manicures can cause nail brittleness, peeling, and even accelerate skin aging or increase the risk of skin cancer on the hands.

In the U.S., the Food and Drug Administration (FDA) has not banned TPO and regulates far fewer chemicals in personal-care products than Europe, leaving consumers with limited oversight.

Experts recommend applying sunscreen before UV exposure, giving nails recovery time, and seeking TPO-free alternatives now appearing on the market.
