Dr. Peterson Pierre, a certified dermatology and cosmetic dermatology specialist at  the  ​Pierre Skin Care Institute​ , explains that UV nail lamps use the same mechanism as  sunbeds so they ​”can pose a risk to skin health “​ .  “Gel manicures use UVA radiation to harden nail polish and make it less likely to splinter.  Ultraviolet rays penetrate deep into the skin and damage collagen and elastin, two proteins  that keep our skin young. This can lead to signs of premature aging such as dark spots  and wrinkles. Cumulative DNA damage can lead to precancerous growths and eventually  skin cancers, “says Pierre.

However, there are several other factors involved. “First is the strength of the bulbs used  that emit different amounts of ultraviolet light. Second, the amount of exposure to that light
and thirdly, the frequency of exposure. Given that manicures are usually performed one or  Twice a month for a few minutes, the amount of exposure to ultraviolet light is relatively  low, especially when compared to sun exposure. Therefore, ​health risks are low, but not  zero,​ “he says.
