Abstract
Many traditional Chinese medicine compositions can moisturize the skin and utilize in cosmetics. Using a combination of Chinese Medicine Materials and guided by Traditional Chinese Medicine principles, this study selected Echinacea purpurea to protect the skin barrier, Dendrobium nobile to clear heat and promote fluid production, Sophora flavescens to clear heat for diminished inflammation, and Aloe vera combined Lycium barbarum to nourish yin, to together form a "poly TCM moisturizing formulation." These poly plant extracts were investigated and optimized for the stability, safety, and moisturizing ability. The combination moisturizing effect was determined by measuring the expression of FLG mRNA, CLDN-1 mRNA, and AQP3 protein. Toxicological analysis included a red blood cell hemolysis test and a 3T3 phototoxicity test. It has been observed that by using polysaccharide yield as the evaluation criterion showed optimal extraction at a material-to-liquid ratio of 1:100, an extraction temperature of 100°C, and an extraction time of 3 hours. Moisturizing effect experiments showed that the expression of FLG mRNA, CLDN-1 mRNA, and AQP3 protein was significantly increased. Toxicological tests showed that the composition was safe and caused no irritating effects. Based on these results, this poly traditional Chinese medicine moisturizing formulation is safe within moisturizing effects and can be used as a moisturizing raw material in cosmetics.
