ABSTRACT
Background@#The adverse effects of particulate matter (PM) on the skin have been concerning recently. @*Objective@#We investigated PM induced inflammation on barrier-interrupted skin and relieving effects of plant extracts on PM-induced skin irritation. @*Methods@#A total of 20 participants were enrolled for the induction of skin irritation. Sodium lauryl sulfate (SLS) patch was affixed to the forearm for 24 hours. After patch removal, total suspended particulates (TSPs) were applied. After inducing skin irritation using SLS and TSP, cream containing 0.1% mixture of plant extracts (Citrus sunki, Sceptridium ternatum (Botrychium ternatum), and Korthalsella japonica) was applied. The a* value, erythema index (EI), and transepidermal water loss (TEWL) were measured. @*Results@#The a* value was significantly higher at the site where TSPs were applied than that at the site where TSPs were not applied at 1 and 2 days after SLS patch removal. The a* value, EI, and TEWL were significantly low in the cream-applied area 7 days after the introduction of the SLS patch and TSPs. @*Conclusion@#PM induced skin irritation in a previously disrupted skin barrier. Topical application of plant extracts alleviated skin irritation symptoms caused by dust exposure.
