Gel manicures commonly use lamps that emit ultraviolet radiation to cure polish. A 2023 laboratory study raised safety questions, but its findings should not be presented as proof that nail dryers cause skin cancer in people.
What the study found
The peer-reviewed study indexed by the National Library of Medicine exposed mouse and human cells to radiation from a UV nail-polish dryer. Researchers observed oxidative stress, DNA damage and mutations in the exposed cells.
What it did not prove
The experiment used cultured cells rather than following people who receive gel manicures. It therefore did not measure the rate of skin cancer in users or establish that a particular manicure schedule causes cancer. Long-term human studies would be needed to quantify that risk.
Practical precautions
The American Academy of Dermatology recommends applying a broad-spectrum, water-resistant SPF 30 or higher sunscreen to the hands before a gel manicure, or using dark, opaque fingerless gloves. Its gel-manicure guidance also suggests reserving gel manicures for special occasions and watching for persistent nail or skin changes.
These steps reduce unnecessary ultraviolet exposure but cannot guarantee zero risk. People with a history of skin cancer, unusual skin sensitivity or medicines that increase sensitivity to light should ask a qualified healthcare professional for individual advice.
