Abstract

Acne is known as the most common skin disease. It commonly occurs during adolescents, but it is also present in children and adults because of air pollution, drug abuse and so on. In addition to the hormonal, genetic and environmental factors, Propionibacterium acnes (P. acnes) have also critical roles in outbreak of acne by inducing inflammatory mediators. Increase of sebum production provides an ideal environment for P. acnes that induce inflammation on the skin by activation of monocytic cells and stimulation of inflammatory cytokines. In this study, natural extracts were investigated for anti-inflammatory effects against inflammatory acne by P. acnes infection in terms of reducing cytokine production. Eucalyptus globulus extracts effectively suppressed mRNA synthesis of inflammatory mediators such as TNF-α, IL-1β, IL-2, and NLRP3 in P. acnes-activated macrophages. Moreover, Eucalyptus globulus extracts inhibit activation of transcription factors, NF-κB and NFAT, which are known as key regulators of inflammatory cytokine production. This study suggests the potential of using Eucalyptus globulus extracts as alternative agents for the treatment of acne.
