The American Academy of Dermatology (AAD). It recommends wearing dark, opaque gloves with the fingertips cut off before getting a gel manicure, specifically to cover the skin during UV exposure. The AAD also notes that repeated exposure during gel manicures can contribute to premature aging of the skin on the hands and increase UV-related risks.
Exposure to tanning beds, which primarily contain high-dose UVA emitters, is a known cause of photoaging. A growing body of evidence suggests a link between the use of tanning beds and the development of skin cancer. UV nail lamps, available for home use and in beauty salons, are another source of high-dose UV-A radiation.
Observations: Two middle-aged women, both in good health and with no personal or family history of skin cancer, developed non-melanoma skin cancers on the backs of their hands. Both reported having been exposed to UV nail lamps in the past.
Conclusions: Exposure to UV nail lamps appears to be a risk factor for skin cancer; however, this finding warrants further research. Furthermore, awareness of this potential association could help physicians detect more cases of skin cancer and better inform their patients.
