According to a new study, ultraviolet (UV) nail polish dryers, often used for gel manicures, can damage cells and cause cancer-causing mutations in cells.
The study on Tuesday in Nature Communications examined cell behavior under two UV exposure scenarios. The cells with acute exposure were subjected to two 20-minute UV dryer treatments separated by one hour. Three days a row, cells with chronic UV exposure were subjected to a 20-minute UV drying session.
One 20-minute exposure to UV dryers resulted in 20 to 30 percent cell death, whereas three consecutive 20-minute sessions resulted in 65 to 70 percent cell death.
In the remaining cells, the radiation caused alterations characteristic of skin cancer.
Ludmil Alexandrov, a bioengineering professor at UC San Diego and author of the study, stated in a release, "We discovered multiple things: first, we saw that DNA is degraded." "We also observed that some DNA damage is not repaired over time, leading to alterations following each exposure to a UV-nail polish drier. In conclusion, exposure may result in mitochondrial malfunction, leading to further mutations. We examined skin cancer patients and observed the exact identical patterns of mutations in these patients as in the irradiated cells."
Numerous studies have warned against exposure to UV lamps in tanning beds, which have proven to be carcinogenic, according to researchers from the University of California, San Diego. However, the potential adverse effects of nail polish dryers have yet to be examined, even though these machines use a different UV radiation spectrum.
"If you look at how these gadgets are presented, you'll notice that they're sold as safe and risk-free," remarked Alexandrov. To the best of our knowledge, however, this is the first time anyone has researched these devices and their molecular and cellular effects on human cells.
The study's authors indicate that frequent users of UV nail polish dryers, such as beauty pageant contestants and estheticians, accounted for many cases of uncommon malignancies in the fingers.
Researchers believe that more long-term data are required to "precisely assess the risk of skin cancer of the hand in those who frequently use UV-nail polish dryers."
Final thoughts
Recent research suggests that UV gel nail polish dryers may be associated with an increased risk of cancer. The UV radiation emitted by these dryers has been found to damage DNA and potentially lead to the development of skin cancer. It is important to use these devices with caution and to limit exposure as much as possible. Additionally, individuals should be aware of the potential risks and take steps to protect themselves, such as using sunscreen on their hands and wearing gloves while using UV gel nail polish dryers. Further research is needed to fully understand the potential dangers of these devices and to develop safe alternatives.
