Are UV Nail Lamps Putting Your Health at Risk?
The Glow-Up That Comes with a Warning Label
Gel manicures have long been the go-to for their chip-resistant shine and salon-polished finish. But recent studies suggest that the UV lamps used to cure these manicures might be exposing your skin to more than just a flawless topcoat.
The Science Behind the Shine
A 2023 study from the University of California, San Diego, revealed that UV nail dryers could cause significant DNA damage in human cells. Researchers found that a single 20-minute session led to 20-30% cell death, while three consecutive sessions resulted in up to 70% cell death. The surviving cells exhibited DNA mutations associated with skin cancer.
Dr. Melissa Piliang, a dermatologist at the Cleveland Clinic, emphasized, “Ultraviolet light from UV nail dryers can cause DNA damage in the cells, just like ultraviolet light from the sun.”
2025: Where the Research Stands Now
As of 2025, the scientific community acknowledges the potential risks associated with UV nail lamps, but definitive conclusions are still pending. A scoping review published in the International Journal of Dermatology analyzed 17 studies and case reports, noting that while UV/LED nail lamps emit predominantly UVA radiation, the levels generally comply with safety guidelines when used correctly. However, higher exposures exceeding safety limits have been observed.
The review highlighted that in vitro studies demonstrate UV nail lamps can induce DNA damage consistent with carcinogenesis. Case reports have described squamous cell carcinoma and actinic keratosis on the hands of individuals with extensive UV nail lamp exposure. Despite these findings, a direct causal link between UV nail lamps and skin cancer has not been conclusively established.
Experts agree that more large-scale, long-term studies are necessary to fully understand the risks. In the meantime, dermatologists recommend precautionary measures to minimize potential harm.
Protecting Your Hands Without Sacrificing Style
If you're not ready to part with your gel manicures, consider these protective measures:
Apply Broad-Spectrum Sunscreen: Use a water-resistant sunscreen with at least SPF 30 on your hands 20 minutes before exposure.
Wear UV-Protective Gloves: Fingerless gloves designed to block UV rays can shield your skin while leaving nails exposed.
Limit Exposure: Reduce the frequency of gel manicures and opt for them on special occasions.
Opt for LED Lamps: Some salons offer LED curing lamps, which emit lower levels of UV radiation compared to traditional UV lamps.
Healthier Alternatives to UV-Cured Manicures
Looking for nail treatments that don't require UV exposure? Here are some options:
Gel-Like Polishes: Brands like Sally Hansen's Miracle Gel and Essie's Gel Couture provide a gel-like finish without UV curing.
Press-On Nails: Modern press-ons come in various designs and are easy to apply and remove.
Traditional Nail Polish: Sometimes, classic is best. Regular polish avoids UV exposure altogether.
