Background High-energy visible (HEV) blue light from LED screens may contribute to premature skin aging by causing oxidative stress and collagen breakdown, especially with prolonged exposure.
Objective To assess awareness and protective practices regarding LED screen-related skin aging and to determine the association between LED screen exposure and self-reported premature aging indicators among adults.
Methods In PNS Shifa Hospital, Karachi, a cross-section study was conducted from October 2023 to May 2024 after getting ethical approval. The age range of 450 participants was 27-40, who were enrolled in the study. A structured online self-administered questionnaire developed using Google Forms and distributed electronically was used to collect data on demographics, LED screen exposure, sunscreen use, and antioxidant products such as vitamin C serums and antioxidant creams. Statistical analysis was conducted using the SPSS version 29.
Results Among 450 participants, prolonged LED screen exposure was associated with self-reported signs suggestive of premature skin aging, including fine wrinkles, pigmentation, dark circles, and hair-related changes. A considerable proportion of participants were aware of the potential harmful effects of LED exposure; however, the adoption of preventive practices such as sunscreen use and antioxidant products was limited. Significant associations were observed between increased screen time and reported aging-related skin changes.
Conclusion Adherence to protective measures remains insufficient even though awareness is at a moderate level. One of the major factors contributing to premature aging is long-term exposure to LED screens, which calls for better public education and digital photoprotection measures.
