For women who are regular with mani-pedi of the gel variety, there is some good news that they do not cause skin cancer.
A new study has said that even if one were to use nail lamps once a week for 250 years, the risks were not that much.
Dermatologists had earlier warned that UV exposure could increase the risk of cancer.
During the study, researchers from Massachusetts General Hospital evaluated the radiation from standard nail lamps, including two models using UV fluorescent bulbs and another which used LED lights. They also calculated carcinogenic effectiveness.
The findings have pointed out that the lamps are safe for more than 250 years of weekly manicures, and even after that time, the risks would be much less, according to study researchers.
