In this study, we searched for bioactive compounds from natural resources with a supercritical extract. We selected the extracts of Chrysanthemum zawadskii, Lufa cylindrica, Paeonia lactiflora, Gardenia jasminoides and Scutellaria baicalensis, as natural materials, and evaluated the effects of their skin barrier function. We found that these extracts increased the transactivation activity of the PPAR-responsive element (PPRE) and the anti-oxidation with different priorities, respectively. In addition, these extracts promoted the expression of proteins related to cornified envelope (CE) formation, such as involucrin. From these results, we suggest that natural materials from supercritical extracts will be pertinent candidates for the improvement of the epidermal permeability barrier function.
