Now a new study by researchers at the University of California San Diego and the University of Pittsburgh in the US has uncovered concerning evidence of damage this overlooked source of radiation could be causing to our hands.
LED nail polish dryers look like little tanning beds for your hands. They use UV light to cure and dry some types of nail polish quickly and cleanly.
The bulb on an LED nail polish dryer is less intense and has a different UV spectrum to a tanning bed, but the few rays it emits still easily penetrate the skin with unknown results.
While previous studies have shown little to no link between nail drying machines and skin cancer at a population level, a new study on the molecular side of things has turned up some concerning results.
Bioengineer and lead author Ludmil Alexandrov says before the study “there was zero molecular understanding of what these devices were doing to human cells.”
“Once I saw the effect of radiation emitted by the gel polish drying device on cell death and that it actually mutates cells even after just one 20-minute session, I was surprised,” Zhivagui says.
Zhivagui is being extra cautious. To her, the possible risks outweigh the benefits. But that doesn’t mean everyone needs to stop getting gel polish manicures immediately.
The risk of developing cancer on the hands from UV nail lamps seems to be very low at a population level among those under the age of 65. Some researchers have interpreted these results as meaning “gel manicures have little to no carcinogenic risk.”
