To investigate the effect of Panax ginseng C.A. Meyer extract (Ginseol K-b1), on skin functionality, we evaluated skin appearance and properties, such as wrinkle formation, skin moisture content, and skin elasticity in the skin of hairless mice damaged by UV irradiation. In addition, the effect of Ginseol K-b1 on collagen synthesis in human dermal fibroblasts was investigated. Female hairless mice were orally administered Ginseol K-b1 for 10 weeks with UV irradiation. Wrinkle formation in the Ginseol K-b1-treated group was significantly suppressed compared to the UV-irradiated group. Skin properties, including skin moisture content and elasticity, of the Ginseol K-b1-treated group were better than those of the control group. In the human fibroblast cells, Ginseol K-b1 treatment enhanced cell proliferation and significantly stimulated collagen synthesis. These results suggest that Ginseol K-b1 is a potent ingredient with anti-aging effects.

To investigate the effect of ethanol extract of Saxifraga stolonifera MEERBURGH on skin care, we measured anti-oxidant and anti-aging activity. S. stolonifera ethanol extract itself had anti-oxidant activity in a dose-dependent manner in DPPH radical scavenging. Silica dose-dependently increased the intracellular ROS generation in RAW 264.7 cells. S. stolonifera ethanol extract inhibited silica-induced intracellular superoxide anion generation, $H_2O_2$ and hydroperoxide generation in RAW 264.7 cells. S. stolonifera ethanol extract significantly inhibited both hyaluronidase and elastase activity, also significantly inhibited MMP-1(collagenase) activity as well. In NIH 3T3 fibroblast cells, S. stolonifera ethanol extract significantly increased collagen-like polymer synthesis, which suggesting the S. stolonifera ethanol extract might be used as hydration and anti-wrinkle agents. From the above results, it is suggested that the main ingredients of S. stolonifera ethanol extract play an important role in anti-oxidant and anti-aging activity.

This study was designed to extracts from Orostachys japonicas were investigated to assess anti-oxidation and biological activity. Phenolic content was maximum of $10.56{\pm}0.32mg/g$ when extracted with 50% ethanol. In anti-oxidative activity, Orostachys japonicus electric donating activity was higher than 80% in both water and ethanol extract at $200{\mu}g/mL$. 2,2'-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical cation decolorization of both water and ethanol extract was higher than 95.0% but antioxidant protection factor of water extract was higher than ethanol extract. Thiobarbituric acid reactive substance of ethanol extract was higher than water extract. For antihypertensive effect determination, angiotesin converting enzyme of water and ethanol extract showed 6.67 and 7.98% each at $200{\mu}g/mL$. Ethanol extract of $200{\mu}g/mL$ showed xanthin oxidase inhibitory effect of 60.85% but was not shown with water extract. Orostachys japonicus ethanol extract showed higher tyrosinase inhibitory activity of 64.59% which was higher than kojic acid of control indicating higher whitening effect. In anti-wrinkle effect, ethanol extract at $50-200{\mu}g/mL$ showed collagenase inhibitory effect of 75.95-85.02% which was higher than 68.91-76.64% of epigallocatechin-gallate of control group. 50% ethanol extract showed higher elastase inhibitory activity than water extract. Therefore, Orostachys japonicus extracts were identified to have high anti-wrinkle effect. These results identify anti-oxidative activity, gout prevention, whitening effect, and anti-wrinkle effect which indicate the possibility as a source for functional material.

In the previous study, we reported the antioxidative activity and inhibition of melanogenesis of Ligularia stenocephala extracts. In this study, inhibitory effect on elastase and production type I procollagen were investigated. The compounds which was investigated were 4-hydroxyacetophenone, vanillin, chlorogenic acid, caffeic acid isolated from Ligularia stenocephala. They were slightly mild on elastase inhibition activity but 4-hydroxyacetophenone, vanillin exhibited good inhibition activity on collagen production. These results suggest that Ligularia stenocephala may have potential as an anti-aging ingredient in cosmetics.

Recently, several researchers have been developing cosmetics from natural ingredients for skin whitening and anti-aging products. The red sea cucumber (RSC), Apostichopus japonicas, is a species of sea cucumber in the family stichopodiae, which is widely distributed in China, Japan, and Korea. To use Red Sea Cucumber as a cosmetic ingredient, its inhibitory effects on melanogenesis and the anti-aging effects of RSC extracts were investigated. First, a tyrosinase activity assay was performed, which showed that RSC inhibited tyrosinase activity at a concentration of $200{\mu}g/ml$. An MTT assay was carried out to evaluate cell toxicity, and the results showed that RSC extract has no cytotoxicity in HaCaT cells. Furthermore, the mRNA expression levels of tyrosinase, tyrosinase related protein 1 (TRP-1), tyrosinase related protein 2 (TRP-2), microphthalmia-associated transcription factor (MITF), and matrix metalloproteinase (MMPs) genes treated with RSC extract in B16F10 and HaCaT cells decreased. Moreover, a wound-healing assay was performed to identify the cell regeneration effect of RSC extracts. Also, a skin turnover effect was confirmed by creating a three-dimensional cell culture with HaCaT and human fibroblasts. Altogether, the results suggested that Red Sea Cucumber may possess a high ability to induce whitening and anti-wrinkle effects as a cosmeceutical ingredient.

Objectives : Corni Fructus (CF) is traditional herbal medicine used on polyuria, low back pain, and tinnitus. This study aimed to evaluate inhibits skin wrinkle formation effect of CF. Methods : To evaluate the produce inhibition effect of CF, SD-rats were distributed into four groups; normal rats (Nor), AGEs (advenced glycation end product)-induced rats (Con), AGEs-induced rats treated with 100mg/kg CF (CF). To induce AGEs, streptozotocin (50mg/kg) was administered intraperitoneally and after 3 days oral administrated 100mM methyl glyoxal for 3 weeks. Results : The oral administration of CF suppressed the reactive oxygen specis (ROS) in serum. The AGEs in skin tissues was significantly reduced through treatment of CF. Furthermore, the expressions of AGEs related proteins such as polyclonal anti-$N^e$-(carboxymethyl)lysine (CML), anti-$N^e$-(carboxyethyl)lysine (CEL), AGE receptors (RAGE) were decreased in CF treated group compared with the control group in skin tissues. Inflammation-related proteins such as Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB), monocyte chemoattractant protein-1 (MCP-1), interleukin-6 (IL-6) reduced in CF treatment group than control group. AGE-induced rats exhibited that the significant decreased collagen however, CF treatment (100mg/kg of body weight) up regulated collagen by improved the expression levels of skin fibril-related genes such as Matrix metalloproteinase (MMP-1). Conclusion : Taken together, our study suggests that CF regulates ROS to prevent accumulation of AGEs and inhibits skin wrinkles. Our finding indicate that CF may be an effective agent for inhibits AGEs formation, and improved skin wrinkle.

This study aimed to investigate the beauty food activities of wild-cultivated ginseng (Panax ginseng C.A. Meyer). wild-cultivated ginseng extracts were analyzed for antioxidant, skin whitening, anti-wrinkle effect was measured in water and 70% ethanol extract. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical decolorization activities of water and 70% ethanol extracts were 16.69 and 2.18% as well as 4.04 and 3.25% at a solid content of $200{\mu}g/mL$, respectively. The antioxidant protection factors (PF) of water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$ were 1.06 PF and 1.09 PF, respectively. Thiobarbituric acid reactive substance (TBARs) were both 96% at a solid content of $200{\mu}g/mL$. As PF and TBARs showed higher activity than DPPH and ABTS, we could know that antioxidant activity in the lipophilic component of wood-cultivated ginseng were superior to water-soluble component of wood-cultivated ginseng. Tyrosinase inhibitory activity was 10.97 and 52.39% in water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$. The collagenase and elastase inhibitory activities as anti-wrinkle effect were 15.71 and 20.43% in water extracts as well as 32.26 and 86.74% in 70% ethanol extract at a solid content of $200{\mu}g/mL$. The results show that anti-wrinkle effect was the best among the other experiments. This extracts from wood-cultivated ginseng, therefore, seems to be a potent beauty food resource against wrinkles.
