The National Academy of Medicine in France has issued a warning about the possible carcinogenic risk of heat lamps used in the application of semi-permanent nail polish, a popular beauty treatment over the last decade. The Academy points out that the process of applying semi-permanent polish requires the use of a lamp that emits UV type A (UVA) rays that can penetrate deep into the skin, which promotes aging and the development of skin cancer. A study published in a specialized journal, Clinics in Dermatology, in 2022 recorded some cases of cancer associated with the use of this type of varnish in previous years.
The Academy acknowledges the need for large epidemiological studies to assess the risk more accurately but notes that the risk appears to be related to three factors: age at onset of use, frequency, and exposure over several years. In addition, it notes that the cumulative effect of UV exposure represents a significant risk, which may be exacerbated in the case of fair skin or immunosuppression in the client.
To reduce the risk, the Academy recommends the application of a sunscreen on the hands 20 minutes before exposure to UV or LED lamps, as well as information campaigns for the general public and professionals, underscoring the risk of continuous application of semi-permanent varnishes, especially in fair-skinned people. Although the Academy warns about the possible carcinogenic risk, it recognizes that more research is needed to determine the magnitude of the risk.
