Gel manicures are a beauty favorite because they’re glossy, long-lasting, and dry quickly. But when it comes to skin and nail health, there’s more to consider than just the finished look. Our dermatologists weigh in on two main aspects of gel manicures—UV/LED curing lamps and the chemicals in the gel polish itself—to help you make informed decisions about your nails.
UV/LED Lamps: What the Evidence Shows
To cure gel polish, salons use UV or LED lamps that emit mainly UVA radiation—the same type of ultraviolet light linked to skin aging and DNA damage. Recent studies have shown that repeated exposure to these lamps in laboratory settings can cause DNA changes in skin cells similar to those caused by sun exposure. However, real-world risk in humans is not fully established.
Experts stress that cumulative UV exposure—whether from the sun or nail lamps—may add up over years, especially if gel manicures are done frequently (every few weeks). While the overall cancer risk from lamps alone is considered low, it’s still pr
