Objectives: This study investigated associations between air pollution and skin aging among residents of Taipei City. Methods: We selected Datong District and Beitou District as research sites. The participants were residents aged 20 to 70 years who had lived in Taipei City for more than 1 year and had no communicable diseases. We used a microscopic skin camera and facial image analysis to measure degrees of skin aging. We investigated factors related to skin aging through self-administered questionnaires. We estimated exposure to PM10, PM2.2, and NO2based on participants' residential address. Finally, we conducted multiple logistic regression analysis to examine association between air pollution exposure and skin aging. Results: A positive and statistically significant association between NO2exposure and skin aging was identified. The risk of skin aging increased with the degree of exposure to NO2over 1 year (OR = 1.05, 95% CI, 1.004 to 1.10). Conclusions: Higher exposure to NO2is associated with a higher risk of skin aging.
