Question:

Can the UV lights used to dry gel nail polish cause skin cancer?

Answer from Nebraska Medicine dermatologist Jennifer Adams, MD:

Gel manicures are popular for their shine and long-lasting wear, but many people wonder about the safety of the UV light used to cure the polish. UV nail lamps emit both UVA and UVB rays. UVA is tied to skin aging, while UVB is often linked to sunburns. Both types of radiation can contribute to skin damage and cancer risk.

We’re exposed to small amounts of UV in everyday sources like fluorescent lighting and LED bulbs, but those lights are usually at least 10 inches away from our skin. With nail lamps or tanning beds, the UV is applied directly on the skin for repeated and prolonged periods.

Unlike medical devices, nail curing lamps aren’t monitored by the FDA. Studies show the intensity of UV light varies widely depending on the brand and how long they’ve been used throughout the day. It’s incredibly variable, but we do know that the UV that comes through is cancer-causing and carcinogenic. In addition to skin cancer, UV exposure can also cause premature aging, sunspots and skin sensitivities.

The risks increase with repeated exposure. If you’re getting gel manicures every two to three weeks, that time under the lamp adds up. There’s even a case of a woman who developed skin cancer on her fingertips after years of regular gel manicures -- she had no skin cancer anywhere else.

If you love manicures but want to lower your risk, try these tips:

• Choose regular or dip polish. These don’t require UV light to set, especially with a quick-dry topcoat.
• Apply sunscreen to your hands. While not fully protective, it reduces the amount of UV that reaches the skin.
• Wear UV-protective gloves. These are special gloves with the fingertips cut out that shield most of your hands from the light.
• Limit how often you get gel manicures. Save them for special occasions instead of every appointment.

If gel polish is your go-to, consider these protective steps. If you’d rather not take the risk, there are safe, non-UV alternatives to keep your nails polished and healthy. Most importantly, see a dermatologist if you notice new growths or spots on your hands.
