  • This study was conducted to identify the efficacy related to skin barrier functions such as anti-inflammatory, anti-allergic, cornified envelope formation and the alleviation effect of keratinocyte damage caused by S. aureus using the callus extract, which was induced and extracted from the leaves of Gynostemma pentaphyllum in Ulleungdo Island. In order to confirm the anti-inflammatory effect of the G. pentaphyllum callus extract on the skin, the expression of inflammatory cytokines was investigated in primary epidermal keratinocytes (HEKa) activated with PAR-2 agonist, and the G. pentaphyllum callus extract showed IL-8, IL-25, and TSLP production inhibitory effect. β-Hexosaminidase assay using RBL-2H3 cells was performed to confirm the anti-allergic efficacy, and G. pentaphyllum callus extract showed the effect of inhibiting the release of β-hexosaminidase. In addition, G. pentaphyllum callus extract showed the cornified envelope formation effect in HaCaT cells, and through the co-culture experiment with HaCaT cells and S. aureus, it showed alleviation effect of keratinocyte damage caused by S. aureus. Therefore, G. pentaphyllum callus extract is considered to be a useful cosmetic material for improving skin barrier with anti-inflammatory, anti-allergic and alleviation effect of keratinocyte damage caused by S. aureus.
