'Apply sunscreen before doing gel nails?': Concerns raised over UV exposure during manicures and pedicures

UV and LED lamps, commonly used to cure gel polish, emit ultraviolet radiation — the same type of rays produced by sunlight. While exposure during a single manicure is brief, specialists say repeated exposure over time can affect skin cells.

For many clients like Margret Wanjiru, manicures are part of feeling put together. “Manicure makes me feel more attractive and well-groomed,” she says, adding that gel polish appeals to her because it lasts longer and retains its shine.

Nairobi-based nail technician Kelvin Muteru says awareness about UV exposure is growing within the beauty industry. “We try to reduce the amount of time hands are under the lamps and use LED where possible. We also advise clients to apply sunscreen before the process,” he says, noting that safety conversations are becoming more common in salons.

Medical experts emphasize that the concern is linked to long-term and repeated exposure rather than immediate harm. Oncologist Dr. Catherine Nyongesa explains that ultraviolet radiation can penetrate the skin and may affect skin cells over time.

Laboratory studies have shown that UV nail lamps can cause changes in skin cells under experimental conditions. However, large population-based studies have not established a direct link between gel manicures and higher rates of skin cancer. As a result, many health professionals describe the overall risk as low, though they recommend precaution for frequent users.

Because the skin on the hands is often exposed, doctors suggest simple protective measures. These include applying broad-spectrum sunscreen about 15–20 minutes before a nail session, using UV-protective fingerless gloves during curing, opting for LED lamps that cure polish faster, and limiting how often gel manicures are done.

As gel nails remain a popular beauty choice, experts say informed decisions and small preventive steps can help balance style with skin safety.
