Abstract Photobiological safety standards are frequently cited to support the safety of ultraviolet (UV) nail lamps used in cosmetic gel services. These determinations rely primarily on erythema-weighted hazard functions developed to assess acute injury from broadband UV sources. However, modern nail lamps emit almost exclusively ultraviolet A (UVA) radiation, a spectral region that is weakly represented in these weighting functions despite well-established roles in oxidative

AI Overview Dr. María Laura Dántola, a photochemist at the Institute of Theoretical and Applied Physical-Chemical Research (INIFTA) in Argentina, led a recent study concerning the effects of UV nail lamps . Her research focused on the  potential for skin damage and premature aging caused by the UV or near-UV lamps used to cure gel nail polish .  Key aspects of her study: Mimicked Salon Conditions:  The study involved simulating salon nail lamp conditions using a chamber to ex

Purpose: To compile information from published studies on the amount of UVA radiation customers are being exposed to during gel manicures, to illuminate the possible damage to the skin and to highlight why the current photobiological standards being used to measure this irradiance are not applicable for the measurement of UVA radiation being emitted from the nail lamps. The concern of skin cancer risk and premature aging of the skin from UV/LED nail lamps used to cure gel pol
