India, Feb. 8 -- Gel manicures promise long-lasting shine and flawless nails, but repeated exposure to curing lamps may have an impact beyond nail health. While these lamps are commonly used in salons and at home, experts say frequent exposure can lead to cumulative skin damage on the hands over time. In a recent Instagram video, anaesthesiologist and interventional pain medicine physician Dr Kunal Sood explained that gel manicure lamps emit UVA radiation (long-wave UV radiation). This long-wave ultraviolet radiation penetrates deeper into the skin and can affect skin cells gradually, especially with repeated use. Gel manicure lamps may look harmless, but they do expose the skin to UVA radiation, even the newer LED-based lamps. "While LED lamps don't emit UVB (short-wave UV radiation), they still produce UVA wavelengths, which are linked to premature skin ageing and increased skin cancer risk. UVA penetrates deeper into the skin and generates reactive oxygen species, which can damage DNA and skin cells over time," Dr Sood explains. According to Dr Sood, occasional gel manicures are unlikely to cause significant harm, but weekly sessions can gradually increase UVA exposure. "During gel manicures, the backs of the hands, fingers, and nail beds receive the most exposure. People at higher risk include those with fair skin, a personal or family history of skin cancer, or significant prior sun exposure," he says. Because the damage from UVA exposure is cumulative rather than immediate, taking precautions consistently is key.
