Nanoparticles are substances that are smaller in size and smaller than cells that make up the skin. Therefore, they are very suitable as mediators for transmitting drugs or genes across cell membranes, and also deliver specific ingredients into the skin.In this study, nanoparticles were extracted from mugwort and particles of around 100 nm were obtained through dynamic light scattering (DLS), and the results of concentration-dependent enhancement of cell viability in fibroblasts were obtained through MTT assay. In addition, it was confirmed that the COL1A1 mRNA expression level was increased and the IL-6 mRNA expression level was decreased through the quantitative real-time PCR analysis method. Moreover, as these nanoparticles were confirmed to be stable, they can be applied not only to cell experiments but also to cosmetic formulations. While the demand for plant-derived ingredients continues to increase, excluding chemical ingredients from the recent cosmetics industry trend, there is a limitation in that there are few research results suggesting the application field of plant-derived nanoparticles. Therefore, in order to overcome the limitations of the cosmetic industry at the present time, the results obtained in this study present nanoparticles derived from Artemisia princeps (NDAP) as a highly functional cosmetic material.

In this study, we prepared Eriobotrya japonica leaf extracts by several extraction processes and then evaluated their biological activities for their potential application as a new raw material of functional cosmetic. Their whitening effects were measured by tyrosinase inhibitory activities, and anti-inflammatory effects were determined by inhibitory activities of nitric oxide (NO) production. Among the several extracts obtained from E. japonica leaf, supercritical fluid extract showed tyrosinase inhibitory activities at the concentration of 10%. Inhibitory activity on NO production effect related to anti-inflammatory efficacy was in the order: supercritical fluid extract > ethanol extract > hot water extract. According to the results of MTT assay, cell cytotoxicity was not observed at all concentrations except for a 5% concentration of the 70% ethanol extract. For whitening effects, 30% ethanol and 70% ethanol extract showed mushroom tyrosinase inhibitory activity at the concentration of 5%. These results indicated that E. japonica leaf extracts could have the functional effects when they are added as ingredients in cosmetics.

The purpose of this study was to investigate the applicability of the Psidium guajava leaf extract as a whitening functional cosmetic material. We measured DPPH radical scavenging activity, intracellular ROS, cytotoxicity in B16F10 melanoma cells and cytoprotective effect on ultraviolet A, in vitro tyrosinase inhibitory effect and melanin biosynthesis inhibitory effect. The antioxidative effect was confirmed through high DPPH radical scavenging activity and intracellular ROS activity inhibition measurement of the Psidium guajava leaf extract. The survival rate of B16F10 melanoma cells was more than 98% at all concentrations, and the cytoprotective effect from ultraviolet ray A was found to increase in a concentration-dependent manner. In addition, in vitro tyrosinase activity inhibitory effect of 10% and melanin biosynthesis inhibitory effect of 20% were observed. Through less toxicity for B16F10 melanoma cell, high antioxidant activity, inhibition of tyrosinase activity and melanin biosynthesis inhibitory effect, we confirmed the possibility of developing the Psidium guajava leaf extract as a whitening functional cosmetic material with a safe and excellent whitening effect.

In this study, we evaluated the possibility of wrinkle-reducing functional cosmetic material of isoquercitrin (IQC) isolated from Nymphoides indica (NP) by measuring the efficacy of ROS inhibition, procollagen synthesis induction, and matrix metalloproteinase (MMP)-1 inhibition. As a result, ROS tended to be inhibited in a concentration dependent manner, and the procollagen protein synthesis rate was increased by 70% ($5{\mu}g/mL$) and the MMP-1 protein was decreased by 41% ($5{\mu}g/mL$) compared with the control. This was suggested the ability of IQC to induce the procollagen synthesis and to reduce the ROS and MMP-1 production. Therefore, it is considered that IQC isolated from NP has enough value to be a functional cosmetic material.
