New research shows that the UV light in these lamps could be harmful to your health, but you may not need to cancel your next appointment.
Gel manicures are popular because they last a long time and don’t easily chip or peel. But they’ve recently come under scrutiny following a study that found that the ultraviolet lamps used for these nail treatments damage cells in ways that could potentially increase the risk for cancer.
In the new study, published in the peer-reviewed journal Nature Communications in January, researchers exposed human and mouse cells to radiation from a popular nail lamp that is used in many US nail salons. Although the cell damage is worrying, Dr Zhivagui said, the study does not prove that UV lamps can cause cancer. Cells in a lab are more vulnerable to damage than cells on a person’s hand, which has a thick outer layer of skin made of dead cells that helps protect against environmental damage, Dr Adigun said.
There’s one concern with dip manicures, though: Stylists often use the same jar of acrylic powder for multiple customers, which increases the possibility that the powder could harbour germs that cause nail infections, Dr Adigun said. To reduce your risk of infection, Dr Adigun suggested asking your stylist not to push back or remove your cuticles, which provide an important barrier against germs. Many people blame post-salon infections on contaminated equipment, she said, when it’s more likely that their own germs infected the nails after their cuticles were removed. “Tell them, ‘please trim my nails, file my nails, do not touch my cuticles’,” Dr Adigun said.
