In this study, plant extracts including 25% Saururus chinensis, 20% Morus bombycis stem and 20% Morus papyrifera stem were tested to use as possible cosmetic agent. As cosmetic effect test, cell toxicity test, elastase inhibition assay, tyrosinase inhibition assay, anti-oxidation assay and temperature stability test were done as cosmetic assays. Plant extract showed low cell toxicity, excellent elastase inhibition and anti-oxidation effect, however, tyrosinase inhibition effect was lower. Skin, lotion and essence formulation was made using plant extracts and temperature stability test was done. Skin and essence indicated good stability, however, lotion showed phase separation and severe viscosity variation, which means lotion formulation change. From the research, plant extracts including Saururus chinensis, Morus bombycis stem and Morus papyrifera stem were suitable for possible cosmetic agent.
