JAMA Dermatology Study Highlight



Bottom Line: Using higher-wattage ultra violet (UV) lamps at nail salons to dry and cure polish was associated with more UV-A radiation being emitted, but the brief exposure after a manicure would require multiple visits for potential DNA damage and the risk for cancer remains small.


Author: Lyndsay R. Shipp, M.D., of Georgia Regents University, Augusta, and colleagues.


Background: The use of lamps that emit UV radiation in nail salons has raised some concern about the risk of cancer, but previous studies have lacked a sampling of lights from salons.


How the Study Was Conducted: The authors tested 17 light units from 16 salons with a wide range of bulbs, wattage and irradiance emitted by each device for their research letter.


Results: Higher-wattage light sources were correlated with higher UV-A irradiance emitted.


Discussion: “Our data suggest that, even with numerous exposures, the risk for carcinogensis, remains small. That said, we concur with previous authors in recommending use of physical blocking sunscreens or UV-A protective gloves to limit the risk of carcinogenesis and photoaging.”
