As much as we enjoy lavishing ourselves with manicures, it is important to be aware of the potential risks involved. Researchers at the University of California, San Diego recently discovered that UV nail dryers used for gel manicures can cause cell death, DNA damage in skin cells, and potentially skin cancer.
The results of the study were shocking; exposure to these devices caused 20-30% cell death after one session and 65-80% cell death after three sessions. Maria Zhivagui, a postdoctoral scholar, was surprised by the results and has since stopped using them. Nail technicians are exposed to hazardous chemicals at a higher rate than workers in the electronic waste industry, according to a study published by the University of Toronto researchers.
UV nail dryers emit ultraviolet radiation that is known to cause DNA damage, but prior research had not established a direct connection between gel manicure UV lamps and permanent skin damage. Researchers subjected human skin cells to a variety of UV lamps used for curing nail gels, measuring the long-term effects on cell viability, DNA damage, and mutation rates. The results revealed that up to 30 percent of cells died after a single session, and more than 60 percent were damaged or mutated after multiple sessions.
Due to the cumulative effect of repeated UV exposure over time, gel manicures pose a heightened risk of developing skin cancer. In light of this new research, those who enjoy getting their nails done frequently should take additional precautions to protect their health. Before undergoing any type of UV light therapy, such as a gel manicure or pedicure, it is advised that individuals apply broad-spectrum physical sunscreen. Additionally, it can be helpful to wear protective gloves or use shields designed specifically for hand protection during manicures and pedicures; this will minimize your exposure while still allowing you to achieve excellent results. In addition, ensure that your salon has adequate ventilation so as not to reduce your exposure further.
It is important for everyone, but especially nail technicians, to be aware of the potential risks associated with UV lamp exposure during gel manicures and pedicures. According to research, these treatments can cause significant skin cell death, DNA damage, and mutations that, if left unchecked, can lead to skin cancer — regular sunscreen use in combination with protective gear can significantly reduce these risks!
