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 expose common skin molecules to UV radiation for the typical 4-minute curing cycle.

• Observed Chemical Alterations: They found that exposed molecules, including tyrosinase (an enzyme crucial for melanin production), became chemically altered and less effective at their functions.

• Impact on Melanin Production: The study specifically noted that tyrosinase, when affected by the UV radiation, showed a reduced ability to produce melanin, which is vital for protecting the skin from UV damage.

• Increased Oxidative Stress: Dántola's team observed that the altered molecules quickly initiated oxidative stress reactions, which can harm cell membranes.

• Concerns About Lack of Regulation: Dr. Dántola and her colleagues expressed concern about the lack of regulation and potential risks associated with frequent exposure to these devices, which are often used without manufacturers reporting on potential hazards. 

Implications of the study:

• Potential for Premature Aging and Cancer Risk: The disruption of melanin production and increased oxidative stress observed in the study suggest a potential link between frequent UV nail lamp use and premature skin aging and a heightened risk of certain skin cancers.

• Advocacy for Informed Choice and Protective Measures: Dr. Dántola believes that sharing these findings allows dermatologists, engineers, and regulators to develop further research, potentially exploring options like UV-protective glove fabrics or alternative nail polish formulations cured by visible light. Until such options become standard, she highlights the importance of informed decision-making by consumers.
