Radiation emitted by nail dryers can damage DNA and cause cancer-causing changes in human cells, new research has found – and you might think the typical gel mani-pedi is a risk. Some dermatologists say the findings in a study published Jan. 17 in the journal Nature Communications aren’t new about the dangers of ultraviolet, or UV, light from any source. In fact, the results confirm why some dermatologists have changed the way they get gel manicures or stopped getting them altogether.” “Tissue damage can lead to skin cancer,” says Dr. Julia Curtis. Tanning beds are listed as carcinogenic and UV nail lamps are minimal. tanning beds for your nail beds to heal gel nails,” said Curtis. Electromagnetic radiation, ultraviolet light has a wavelength of 10 to 400 nanometers, according to the UCAR Science Education Center. Ultraviolet A light (315 to 400 nanometers), found in sunlight, penetrates the skin. “They penetrate and are widely used in UV nail dryers, which have become popular in the past decade. According to a news release for the study, tanning beds use 280 to 400 nanometers, while the spectrum used by nail dryers is 340 to 395 nanometers. We should be concerned,” said corresponding author Ludmil Alexandrov. he said in a news release. “But as far as we know, no one has really studied these tools and how they affect human cells at the molecular and cellular level.” Alexandrov holds dual titles as Associate Professor of Bioengineering and Cellular and Molecular Medicine at the University of California, San Diego. Researchers exposed human and mouse cells to UV light, and a 20-minute session caused 20% to 30% of the cells to die. . Three consecutive 20-min exposures resulted in 65% to 70% death of exposed cells. The rest of the cells suffered mitochondrial and DNA damage, which led to the changes seen in human skin cancer. The biggest limitation of the study is that the exposure of cell lines to UV light is different from studies on living humans and animals. says dermatologist Dr. Julie Rusak, founder of Rusak Dermatology Clinic in New York City. Rusak was not involved in the study. “When we do it (with radiation) in a human hand, there’s definitely a difference,” Rusak said. “Most UV irradiation is absorbed by the surface of the skin. When you’re directly irritating the cells in a petri dish, that’s a little different. You don’t have any protection from the skin, the cornea, or the top layers. It’s just that. Very direct UVA irradiation.” But this study, combined with previous evidence — such as reports of people with squamous cell carcinomas, the second most common skin cancer, in association with UVA dryers — “definitely means we need to think more about exposing our hands and fingers to UVA light without protection.” It just is,” says Dr. Shari Lipner, associate professor of clinical dermatology and director of the nail division at NewYork-Presbyterian Hospital/Weill Cornell Medical Center. Lipner was not involved in the study.Reducing Your Risks If you’re concerned about gel manicures but don’t want to give them up, there are some precautions you can take to mitigate the risks. titanium around the nail, and when it’s time to treat your nails, wear cut-off UV gloves,” says Curtis, who doesn’t have a gel manicure. “I recommend alternatives to gel nails, like the new wraps available online.” (They are products.) Some salons use LED lights, which “give off no UV light or very, very low amounts.” “She gets regular manicures — which typically last seven to 10 days — not because she’s trying to avoid UV light, but because she doesn’t like the acetone-thinned nail polish in gel manicures,” Lipner said. Only regular hand washes. It air dries,” she adds. “A gel manicure must be cured or sealed, and the polymers in the polish can only be activated by UVA lights.” And they can be treated before they become serious problems. (Ultraviolet rays also age the skin, causing sun spots and wrinkles to appear.) There isn’t enough data for experts to judge how often people can get gel manicures without putting themselves at risk, Lipner said. But Curtis recommends saving them for special occasions. She doesn’t get a gel manicure very often, but when she does, she uses sunscreen and gloves, she said. Applying a serum rich in antioxidants like vitamin C beforehand can help, she says.” As a dermatologist, I change gloves 3 or 4 times with just one patient. And with normal nail polish, it changes three after four gloves. , the nail polish is gone,” Rask added. “Gel manicures definitely have much better longevity, but is the risk of photoaging and skin cancer really worth it? Maybe not. “People with a history of skin cancer, or those who absorb more photos due to fair skin or albinism, should be more careful with medications or immunosuppressants, experts said. Whether you’re at high risk or not, dermatologists urge CNN to be careful.” “Unfortunately, complete protection is not possible, so my best advice is to avoid these dryers altogether,” Zeichner said.
Radiation from nail dryers can damage DNA and cause cancer-causing changes in human cells, new research has found — and you may be wondering if that classic gel mani-pedi is worth the risk.
Some dermatologists say the findings in a study published Jan. 17 in the journal Nature Communications are nothing new about the dangers of ultraviolet, or UV, light from any source. In fact, the results confirm why some dermatologists have changed the way they get gel manicures or stopped getting them altogether.
“The findings add to previously published data on the harmful effects of UV rays and show direct cell death and tissue damage that can lead to skin cancer,” said Dr. Julia Curtis, assistant professor of dermatology at the University of Utah. , who was not involved in the study.
“The cuticles are listed as carcinogenic for gel nail treatments and UV nail laps are the tiny cuticles of your nails,” Curtis said.
A type of electromagnetic radiation, ultraviolet light has a wavelength of 10 to 400 nanometers, according to the UAR Science Education Center.

Reducing your risk
If you’re concerned about gel manicures but don’t want to give them up, there are some precautions you can take to mitigate the risks.
“Apply broad-spectrum sunscreens that contain zinc and titanium to the nail area, and wear cut-off UV gloves when it’s time to treat your nails,” says Curtis, who doesn’t give gel manicures. “I recommend alternatives to gel nails, such as the new wraps available online.” (Gel nail wraps or strips are gel-based products that don’t always need to be set with UV nail dryers.)
Some salons use LED lights, which “are supposed to give off no UV light or much, much less,” Lipner said.
Lipner gets regular manicures — which typically last seven to 10 days — not because she’s trying to avoid UV rays, but because she doesn’t like dipping the nail thinner in the acetone in a gel manicure.
“Normal hand washes are air-dried,” she added. “Gel manicures must be protected or sealed, and the polymers in the polish must be activated, which is only with UVA lights.”
If you regularly get gel manicures, Lipner recommends seeing a board-certified dermatologist to screen for any precancerous skin conditions and treat them before they become serious. (Ultraviolet light can also age skin, showing up as sun spots and wrinkles, she said.)
Lippner said there isn’t enough information for experts to gauge how often people can get gel manicures without putting themselves at risk. But Curtis recommends saving them for special occasions.

People with a history of skin cancer or who are sensitive to photons due to skin or albinism should be more careful about taking medications or immunosuppressants, experts said. Whether you’re at high risk or not, dermatologists urge CNN to take precautions.
