If you frequent the nail salon, this news is for you: Researchers say there could be a cancer risk associated with the ultraviolet lamps used for nail polish drying.
But the risk varies according to the kind of bulb used at the nail salon.
Dr. Lyndsay Shipp and colleagues calculated that at some salons, it may only take 24 visits to accumulate DNA damage caused by ultraviolet radiation that could cause cancer.
At other salons, it would take 625 visits.
More research is needed, Shipp told TIME.com. In the meantime, rest assured one manicure won’t give you cancer.
But if you’re concerned, or have a family history, you could wear sunscreen for the ultraviolet light, or just air-dry your nails.
