The influence of airborne particulate matter (PM) on skin has primarily been studied in patients with diseases such as atopic dermatitis. Recently, the effect PM healthy human gained attention.To evaluate relationship between concentration and objective changes subjects.This prospective study enrolled 25 volunteers without any disease. Data regarding daily meteorological parameters air pollution were collected during a high-PM period low-PM for 14 days. Environmental lifestyle factors that might conditions subjects also period. Biophysical transepidermal water loss (TEWL), hydration, erythema index, melanin index measured. Pores, wrinkles, sebum, tone evaluated using facial analysis system.Mean TEWL value was significantly higher than (10.16 g/m2/h vs. 5.99 g/m2/h; p=0.0005). Mean (4.3 3.42; p=0.038). For system indices, uniformity (p<0.0001). In addition, increasing PM10 PM2.5, showed increase when other environmental components constant (regression coefficient [RC]=0.1529, p<0.0001 PM10; RC=0.2055, p=0.0153 PM2.5).Increased concentrations may contribute to disturbed barrier function, increased erythema, uneven even skin.
