A recent study conducted by a medical university based in Seoul, South Korea shines new light on how Particulate matter(PM)-PM10 and PM2.5 can lead to premature aging and wrinkling of skin despite using sun protection.
Data collected from a smart phone application based facial analysis system revealed significantly greater wrinkling in periods of high particulate matter exposure.
Other quantitative analyses have revealed significantly increased occurrence of erythema, atopic dermatitis and other allergic skin diseases. Increased skin dehydration - measured as an increase in Total Epithelial Water Loss(TEWL), an indicator of skin barrier function and aging of skin was also noted. The effects were attributed to direct penetration of the PM in the skin , as well as free radical generation.
The solution? At an individual level limiting exposure through barrier protection methods, like using masks and face covers; avoiding smoking or exposure to second hand smoke; a low glycemic diet to improve overall skin health can be helpful. The use of HEPA air purifiers is also beneficial. At the community level, implementing policy driven reduction in overall PM levels holds promise.
