According to a recent study, exposure to UV light can promote skin cancer-related mutations and cell death.
According to a new study, ultraviolet (UV) nail polish dryers, which are frequently used for gel manicures, can damage cells and cause cancer-causing mutations in cells.
Cells were examined in two separate UV exposure circumstances for the study, which was published in Nature Communications on Tuesday. The UV dryers were used on the cells for two 20-minute sessions, with an hour in between. Cells with chronic exposure received one 20-minute session every day for three days in a row from the UV dryers.
Researchers discovered that three consecutive 20-minute UV dryer sessions resulted in 65 to 70% cell death while a single 20-minute session caused 20 to 30% cell death.
The exposure led to alterations in the remaining cells that are frequently found in skin cancer.
Professor of bioengineering at UC San Diego Ludmil Alexandrov, who is also the study’s author, stated in a release, “We saw multiple things: first, we saw that DNA is degraded. “Additionally, we observed that certain DNA damage is not gradually repaired and does result in mutations following each exposure to a UV nail polish drier. Finally, we saw that exposure could lead to mitochondrial malfunction, which could bring about more mutations. The exact identical patterns of alterations that we observed in the irradiated cells were present in the skin cancer patients we examined.”
Numerous studies have been done cautioning against exposure to UV lamps in tanning beds, which have been shown to be cancer-causing, according to researchers at the University of California San Diego. Despite using a different spectrum of UV radiation, nail polish dryers have not been researched for their potential negative effects.
According to Alexandrov, “If you look at how these gadgets are presented, they are advertised as safe, with nothing to be concerned about.” To the best of our knowledge, however, no one has ever examined how these gadgets impact human cells at the molecular and cellular levels.
According to the study’s authors, those who frequently obtain gel manicures using UV nail polish dryers, such as pageant contestants and estheticians, are at an increased risk of getting uncommon malignancies in their fingers.
In order to “accurately evaluate the risk for skin cancer of the hand in those routinely using UV-nail polish dryers,” researchers contend that further data spanning several years is required.
