Warning: Common Grooming Tool Linked to DNA Damage and Higher Cancer Risk

A New Study Reveals the Hidden Dangers of UV Nail Dryers

A groundbreaking study published in Nature Communications has shed light on the potential risks associated with UV nail dryers. Researchers from the University of California, San Diego, and the University of Pittsburgh have discovered that these popular devices may increase the risk of developing cancer-causing mutations and damage DNA.

UV nail dryers, which use ultraviolet light to cure gel nail manicures, have gained widespread popularity in recent years. They are commonly used in both homes and nail salons. However, the study found that exposure to the typical amount of radiation emitted by UV nail dryers can have detrimental effects on human and mouse cells.

The researchers observed that a 20-minute session under a UV nail dryer led to the death of 20 to 30 percent of cells. Repeating this process three times resulted in the death of 65 to 70 percent of exposed cells. The surviving cells experienced mitochondrial and DNA damage and developed mutations often associated with skin cancer.

It is important to note that ultraviolet light has a wavelength of 10 to 400 nanometers, and the higher the wavelength, the deeper the radiation penetrates the skin. UV nail dryers typically use light with a wavelength of 340 to 395 nanometers, similar to the light used in tanning beds.

“Tanning beds are listed as carcinogenic and UV nail lamps are mini tanning beds for your nails,” says Dr. Julia Curtis, an assistant professor of dermatology at the University of Utah.

The study has prompted one of its authors, Maria Zhivagui, to completely avoid UV nail dryers. She was alarmed by the radiation’s effect on cell death and its ability to mutate cells even after just one 20-minute session. Zhivagui stated, “I found this to be very alarming, and decided to stop using it.”

Interestingly, this study is seemingly the first of its kind to examine the effects and potential risks of UV nail dryers. Ludmil Alexandrov, one of the authors, highlights the lack of research on these devices and their impact on human cells at the molecular and cellular levels.

While complete protection may not be possible, dermatologists recommend taking precautionary measures when using a UV nail lamp. Dr. Julia Curtis suggests applying broad-spectrum sunblock containing zinc and titanium around the nails and wearing UV gloves with the fingertips cut off during the curing process. However, Dr. Joshua Zeichner advises avoiding these dryers altogether.

Stay Informed and Stay Safe

This study serves as a wake-up call for those who regularly use UV nail dryers. It is crucial to be aware of the potential risks associated with these devices and take necessary precautions to protect your health. By staying informed and making informed choices, you can prioritize your well-being.
