  • The purpose of this study was to evaluate and verify the effectiveness of sustainable cosmetic raw materials developed from Gynostemma pentaphyllum, a plant native to Ulleungdo, in improving the skin barrier function and treating atopic dermatitis. Cells were derived from adult Gynostemma pentaphyllum plants, and suitable conditions for mass culture of the cells were established in a bioreactor. DNA components and amino acids extracted from this mass culture were identified from the HPLC fraction. In the in vitro efficacy evaluation results, changes in the expression levels of skin barrier-related proteins such as filaggrin (FLG) and Zonula occludens-1 (Zo-1) were insignificant. It was confirmed that the expression levels of the proteins thymic stromal lymphopoietin (TSLP) and interleukin-33 (IL-33) were significantly reduced. These results lead to the conclusion that Gynostemma pentaphyllum cell extracts have significant anti-inflammatory effects and that these extracts can be widely used as sustainable, nature-friendly active material in cosmetics with anti-inflammatory effects and targeted at improving atopic dermatitis.They may find use in anti-aging cosmetic products as well.
