Researchers discovered that UV nail varnish dryers can cause DNA damage or mutations.

Nail polish has been a popular choice in nail salons around the United States since 2010. Gel nail polishes last longer than traditional ones and are more resistant to smudges and wear. The best part is that gel manicures don’t take more than an hour to dry. The polish handles provide all these benefits. Instead of waiting for gel polish to dry naturally under a UV lamp, place your hands in a UV light to activate the chemicals within the gel and cause it to harden.

While the dangers of UV rays—particularly in tanning sites—are well known, it was not until this week that scientists studied how the UV lights used to cure gel polishes could affect human skin. Although you might think that all we know about tanning beds is applicable here, nail salons emit a different type of ultraviolet light. A group of researchers from After reading an article about a contestant in a beauty pageant who was diagnosed as having a rare form skin cancer, I decided that I would study the devices.

Researchers used different groups of human and mouse cell types to find that an 20-minute session using an ultraviolet nail polish dryer caused the death up to 30% of the cells in a Petri dish. 65 to 70% of the exposed cells died after three consecutive 20-minute sessions. The researchers found evidence of DNA and mitochondrial damage in the remaining cells. They also observed mutations in patients with melanoma.

The paper states that “our experimental results and prior evidence strongly suggest that UV nail polish drying devices may cause hand cancers” and that UV nail polish drying devices, which are similar to tanning beds may increase the risk for skin cancer. A study published in the journal Tuesday. Tuesday.

Although you might think that the advice is to avoid UV dryers, it’s not so simple. Gel manicures are a standard industry practice for a reason. Many people find that regular nail polish wears off within a day. This makes it difficult to justify spending the time, money and effort to maintain your nails.
