In this study. we evaluated anti-aging activity of medical plants that protect the skin cell damage induced by UV irradiation. We have investigated diverse biological activities of Selaginella tamariscina as an anti-aging ingredient of cosmetics. S. tamariscina was found to show scavenging activities of radicals and reactive oxygen species (ROS) with the $IC_{50}$ values of $65.1{\mu}g/mL$ against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and $40.9 {\mu}g/mL$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. For testing intracellular ROS scavenging activity, the cultured human dermal fibroblasts were analyzed by increase in dichlorofluorescein (DCF) fluorescence upon exposure to UVB $20 mJ/cm^2$ after treatment of S. tamariscina. UVA-induced MMP-1 protein and mRNA expression in human dermal fibroblasts were reduced in a dose-dependent manner by S. tamariscina. Moreover, S. tamariscina inhibited MMP-2 (gelatinase) activity in UVA-irradiated human dermal fibroblasts assayed by zymography and semi-quantitative RT-PCR. Taken together, these results suggest that S. tamariscina may act as an anti-aging agent by Increasing collagen and preventing the skin cell damage induced by UV irradiation, and imply that S. tamariscina nay be useful as a new ingredient for anti-aging cosmetics.

We re-classified traditional medicinal prescriptions in Dong-Eui-Bo-Gam for the modern application using Tradimed database. They could be devided into 6 categories by the definitions of the related laws. Herbal ethical drugs are the majority, 3926 items, account for 60.21% of total items. Herbal Health Functional Foods stands second, 1480 items, 22.70%, Herbal over the counter drugs are 893 items, 13.69%. These three categories are about 83% of total items. Herbal medical supplies are 158 items, 2.42%, Herbal medical tools are 44 items, 0.67%, Herbal cosmetics are 20 items, occupied 0.31 %. Therefore we have known that traditional medicinal prescriptions can be used not only as drugs, but also as funtional foods, cosmetics, and tools. So they should be developed as modern products to make best use of them. And we suggested that we need official criteria of herbs of careful use and higher standards for herbs which can be used as foods.

Astragalus membranaceus Bunge is used in herbal medicine in Eastern Asian countries including Korea. In this study, we assessed the effects of A. membranaceus extract (AM) on the aquaporin-3 (AQP3) protein expression in HaCaT cells. AM did not affect viability of HaCaT cells. AQP3 expression and cell migration seem to be maximal at $100{\mu}g/mL$ concentration. Epidermal growth factor receptor (EGFR) kinase inhibitor, PD153035, blocked AM-induced AQP3 expression and cell migration. In addition, an 80% ethanol extracts of herbal prescription, SinhyoTakleesan (ST), which is composed of A. membranaceus, Angelicae gigantis, Glycyrrhiza glabra Linne, and Lonicera japonica Flos also induced AQP3 expression at $20{\mu}g/mL$ in HaCaT cells. Collectively, these results suggest that AM induce AQP3 expression via EGFR pathway.

Pycnogenol extracted from pine bark is a component with great antibacterial activity and antioxidant effect. It is applied as a natural anti-inflammatory agent with various medical effects including anti-inflammatory effects, regulation of blood pressure, regulation of the immune system, and inhibition of cancer cell growth. However, research related to cosmetics is limited. Therefore, in this study, the effect of Pycnogenol on the skin was studied through a clinical approach. Changes in skin condition were observed after using cosmetics with Pycnogenol and without Pycnogenol for 6 weeks for 10 clinicians in each group. We observed the effect of pore reduction, wrinkle reduction around eyes, a decrease of the number and angle of loose pores, and reduction of pigmentation. Therefore, cosmetics containing Pycnogenol have the effect of improving skin problems of aging skin.

The reactive oxygen species generated by ultraviolet rays causes various types of cutaneous damage, such as lipid peroxidation and denaturation of the extra-cellular matrix. The accumulation of such damage contributes to skin aging, especially the formation of wrinkles. This study was carried out to develop functional cosmatic by using Oriental herb supercritical extracts (OHSE) for prevention of skin. Effects of OHSE on anti-oxidation, collagenase inhibition and collagen synthesis in normal human fibroblast were investigated. OHSE showed antioxidative activity as high as vitamin C, trolox and DL-penicillamine. Also OHSE showed promotive effect on collagen synthesis and inhibitory effect on collagenase activity. From this results, we conclude that OHSE may have the potential to be conveniently used as an additive in cosmetics for prevention and improvement of skin aging.

The production of matrix metalloproteinases (MMPs) by the UV irradiated skin fibroblast and the degradation of exracellular matrix (ECM) by these enzymes is known as one of the main reasons of photoaging. In this study, to investigate the relationship between aging and Spatholobi caulis extract, we examined the effects of antioxidant, in vitro MMP inhibition and expression of UVA-induced MMP-1 in human dermal fibroblasts. Spathoiobi caulis extract was found to show scavenging activities of radicals and reactive oxygen species (ROS) with the $IC_{50}$ values of $45.81{\mu}g/ml$ against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and $3.11{\mu}g/ml$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. Spatholobi caulis extract inhibited the activities of MMP-1 in a does-dependent manner and the IC50 value calculated from semi-log plots was $31.96{\mu}g/ml$. Also, UVA induced MMP expression was reduced $74.66\%$ by treatment with Spatholobi caulis extract, and MMP-1 mRNA expression was reduced in a dose-dependent manner. Therefore Spatholobi caulis extract was able to significantly inhibit MMP expression in protein and mRNA level. All these results suggested that Spatholobi caulis extract may act as an anti-aging agent by antioxidation and reducing UVA-induced MMP-1 production.
