Study Suggests Doing Manicures with Nail Polish Dryers Could Damage Hand DNA

Scientists Discover Prolonged Exposure from Nail Polish Dryers Can Put Hands at Risk of Developing Cancer

A group of researchers has uncovered that frequent exposure to the ultraviolet (UV) radiation source emitted by nail polish dryers in beauty salons could be damaging the skin cells on the hands and put them at risk of developing cancer. The findings of the new study, recently published in the journal Nature, suggest that these devices may harm individuals although the UV rays of these machines are much lower than those of a solarium.

Ludmil Alexandrov, lead author of the study, and his team noticed that multiple people with cancer in their hands were often exposed to lights from these machines, and wanted to find out more. To uncover their effects, the scientists exposed mouse and human cells to the UV rays of nail polish dryers for consecutive 20-minute sessions, with an hour of rest in between. It was seen that 20-30 percent of the cells had died, and the death rate went up to 70 percent after three days of exposure. This led to DNA damage and mutations associated with skin cancer.

The researchers made it known that direct evidence of cancer formation is yet to be established, but that there is a strong possibility of a health risk especially with frequent exposure to the UV radiation. To accurately determine the risk of developing cancer in individuals who consistently use nail polish dryers, epidemiological studies are necessary and likely to take around a decade to carry out.
