Background: Dissecting the complex relationships between skin aging and air pollution has been an ongoing effort. The increased exposure to air pollution over time imposed a negative effect on skin. This study explores the correlation between skin aging in the Asian population and levels of air pollutants to show differential effects of air pollutant.Materials and Methods: This study was a retrospective trial which included 389 patients, age between 30 and 74, who received a session of ND YARG laser treatment in KMUH (Kaohsiung Medical University Hospital) from 2006 to 2019. Preoperative skin condition quantified by VISIA Complexion Analysis System (Canfield Imaging Systems, Fierfield, NJ, US). Eight air pollutants such as CO, NMHC (non-methane hydrocarbon), NO, NO2, NOx, PM2.5, PM10, O3, SO2 and 8 skin condition such as spots, wrinkles, textures, pores, UV spots, brown spots, red area and porphyrin were analyzed to explore correlation between air pollution and skin aging. Results: Strong correlation were found between NMHC exposure and texture, pores and brown spots formation. A positive correlation between O3 and better VISIA texture and pores scores was found. Brown spots was found to negatively associate with CO, NMHC, NO2, NOx, PM10, PM2.5, and SO2. The skin condition of population over age 45 affected by CO, NMHC, NO2, NOx, PM2.5, PM10, and SO2. Skin condition of the bottom 10% strongly correlates with exposure to PM10 and SO2, whereas skin condition of the top 10% was affected by PM10.Conclusions: Air pollutants such as CO, NO2, NOx, PM2.5, PM10, SO2, and NMHC were found to correlate with negative skin quality strongly. In contrast, O3 exposure is associated with less texture and pores, which implies that air pollutants can have differential effects on skin condition. Future studies are warranted to further appreciate the effects on skin. |
