Proposed mechanisms for antioxidant and anti-skin aging activities of Centella extract. Pre-treatment with Centella extracts prevent H2O2-induced cytotoxicity on dermal fibroblasts by upregulation of cellular antioxidant machineries. Supplementation with CE upregulated CAT, GPx1 and SOD1 expression, whereas pre-treatment with APE induced SOD2 expression following H2O2 treatment. Moreover, pre-treatment with CE or APE suppressed H2O2-mediated-upregulation of MMP-9. This figure was created with BioRender.com.
