Radiation from nail dryers may damage DNA and cause cancer-causing mutations in human cells, a study has found — and that might have you wondering whether your regular gel mani-pedi is worth the risk.in the journal Nature Communications, aren’t new when it comes to concerns about ultraviolet, or UV, light from any source. In fact, the results reaffirm the reason why some dermatologists have changed the way they get their gel manicures or have stopped getting them altogether.
A form of electromagnetic radiation, ultraviolet light has a wavelength ranging from 10 to 400 nanometers, according to theUltraviolet A light , found in sunlight, penetrates the skin more deeply and is commonly used in UV nail dryers, which have become popular over the past decade.
“When we’re doing it inside human hands, there’s definitely a difference,” Russak said. “Most of the UV irradiation is absorbed by the top layer of the skin. When you irradiate cells in the petri dish directly, that’s slightly different. You don’t have any protection from the skin, from corneocytes or the top layers. It’s also very direct UVA irradiation.”
Some salons use LED lights, which “are thought to emit either no UV light or much, much lower amounts,” Lipner said.
