Skin aging is a natural phenomenon. There are internal and external factors of skin aging. The internal factor of skin aging is from the wearing down of the body over time. The external factors are more noticeable from habits such as smoking, excessive alcohol, malnutrition, and extended exposure to UV rays. Completely stopping skin from aging is impossible but one can slow down and treat external signs of skin aging. In western medicine, the following methods are used to reduce the appearance of skin aging: applying lotions and creams containing ingredients such as fruit acid, antioxidants, plant exracts, depigmentation, moisturizer, retinoids, and sun block; botulinum toxin injections; chemical peels, laser and other painful methods remove the top layer of skin to promote new skin growth; fillers are injected to increase soft tissue growth; surgery. In oriental medicine, the following methods are used: acupuncture into facial muscles which stimulates acupuncture point; applying topical treatments and cosmetics containing herbs are effective of preventing skin aging and wrinkles. Above all thing, medicine that helps maintain essence and blood in the skin can be fundamental.

Objectives : The aim of this study was conducted to test dry infant skin by external application with herbs in cosmetics. Methods : A total of 25 infants who visited Daegu Hanny Oriental Medical Center from March 5th, 2008 to May 18th, 2008 were included in this study. In this study, they were treated with the cosmetic products(body wash, rotion, cream) containing herbs. For 4 weaks skin moisture content was measured by corneometer ClVI825. And satisfaction after using body wash, rotion, cream was checked. Results : There were no significant differences on sex and age. Change of skin moisture content between before treatment and after treatment (2, 4 weeks) showed significant changes(p<0.05). Satisfaction after using body wash, rotion, cream was near good. Conclusions : Considering the above results, we have concluded that cosmetics containing herbs have the remarkable effect on infant skin mosturizing.

We investigated the effects of aqueous extracts from twelve medical herbs on ${\alpha}$-melanocyte stimulating hormone (${\alpha}$-MSH)-induced melanogenesis in B16F10 mouse melanoma cell. The cells were incubated with ${\alpha}$-MSH and aqueous extracts 5 days and 2 days and then analysed melanin amount and tyrosinase activities, respectively. Nine aqueous extract of herbs examined at 1 mg/m${\ell}$ level decreased melanin synthesis in B16F10 cell, especially in Agastache rugosa, Leonurus siviricus and Murus bombycis. The significant decrease of released extracellular melanin were also observed in treated cells with aqueous extract from Leonurus siviricus, Murus bombycis and Ledebouriella seseioides. The ${\alpha}$-MSH-induced activation of tyrosinase was inhibited in cells treated with aqueous extract from Cuscutae semen, Angelica tenuissima and Agastache rugosa. These results suggest that herbs inhibiting melanogenesis through tyrosinase activity may apply to develop whitening drugs and cosmetics.

Melanogenesis is a physiological process resulting in the synthesis of melanin pigments, which play a crucial protective role against skin photocarcinogenesis. The heart wood of Caesalpinia sappan L.(C. sappan) has long been commonly used in Oriental folk medicines to promote blood circulation, and as an emmenagogue, analgesic or anti-inflammatory agent as well as a remedy for thrombosis. From the heartwood, many constituents have been purified and among them, brazilin and hematoxylin are two of the most abundant. This present study was designed to investigate the inhibitory effect of butanol extract from C. sappan on proliferation and melanogenesis in Melan-a cells. After 48 h treatment of these cells with various concentrations of butanol extract, the cells showed a dose-dependent inhibition in their proliferation without apoptotic cell death. Therefore, the growth retardation by the extract may be due to the cell arrest or cell differentiation. We also estimated total melanin content as a final product and activity of tyrosinase, a key enzyme, of melanogenesis in Melan-a cells. The melanin content and tyrosinase activity were deσeased in extract-treated cells in a dose dependent manner compared to control group. The butanol extract also resulted in a decrease of melanin content in ${\alpha}-melanocyte-stimulating$ hormone (MSH)-induced melanogenesis, indicating that butanol extract of C. sappan could be developed as skin whitening components of cosmetics.

To develop a new anti-skin aging cosmetics or functional foods by using antioxidative activity and collagenase inhibitor, a potent collagenase or elastase inhibitor was screened from various extracts of medicinal plants and its optimal extraction condition was investigated. And antioxidative activity, antimicrobial activity and inhibitory of effect against collagenase activity were investigated. In the these results, we selected the Sanguisorba (Sanguisorba officinalis L.) that presents a potential biological activities. Sanguisorba which is very rich in triterpenoid saponin and tannins was recently reported its anti-oxidant activities and phytoestogenic activities in vivo test and many clinical studies. The experiments were carried out in vitro to determine anti-oxidant activities of Sanguisorba extracts on DPPH radical scavenging activity assay, Superoxidase scavenging activity assay, Elastase and collagenase activity assay. It show that the Sanguisorba extracts have the most significant anti-oxidant on free radical scavenging activity assay, and also inhibited significantly activities of elastase, collagenase. Further, Sanguisorba extracts are activated Type I collagen protein expression in CCD-986sk cells. These result suggest that the Sanguisorba extracts on DPPH radical scavenging activity assay, Superoxidase scavenging activity assay, elastase and collagenase activity assay, Type I collagen protein expression in CCD-986sk cells effected could be developed cosmetic ingredients for anti-aging.

Objectives : The present study was designed to investigate effects of Ssanghwa-tang (Shu$\bar{a}$nghu$\bar{a}$-g$\bar{e}$ng) on oxidation/reduction reaction-related and aging-related enzymes $in$ $vitro$. Methods : We performed MTT assay, collagenase inhibition assay, elastase inhibition assay, tyrosinase inhibition assay, DPPH free radical scavenging assay, SOD-like activity and xanthine oxidase (XO) inhibition assay. Results : The 50% ethanol (EtOH) extract of Ssanghwa-tang (SHT) showed 55% inhibition of collagenase activity, and 42% inhibition of elastase activity at 1 mg/ml concentration. Also it's treatment showed 18% inhibition of tyrosinase activity, to relate whitening effect, at the same dose of 50% ethanol extract of SHT. Antioxidant activities were determined by DPPH radical scavenging, XO inhibiting activity and SOD-like activity. These scavenging, XO-inhibiting and SOD-like activities were measured in 80%, 75%, and 28% inhibitions, respectively, at a 1 mg/ml treated dose, compared to those of control. The inhibitory effects of 50% EtOH extract on aging and oxidation-related enzyme activities were higher than those of water extract and 95% EtOH extract. Conclusions : Taken together, our findings suggest that the SHT has potential and applicable benefits for development of cosmetics to have anti-aging (anti-wrinkle and whitening) and anti-oxidation functions.

Objectives : This study was designed to investigate the effects of alcoholic fermentation extract from ovary and rind of pear on human skin. Methods : We investigated the effects of samples on human skin in terms of clinical trial. 32 of healthy volunteers, who lived in mokpo participated in clinical trial. Effects of sample on hygroscopicity and water-holding capacity were investigated. Sebum, moisture, scabrousness and desquamation were also investigated. Facial massages were conducted 8 times in each volunteers. Results : Single treatment group showed elevated levels of hygroscopicity (Normal : 106.4$\pm$2.1%, vs Pear : 114.1$\pm$6.2) and water-holding capacity (Normal : 87.1$\pm$4.4%, vs Pear : 96.2$\pm$1.3) on forearm of 16 volunteers respectively. In addition, massage group using sample showed elevated moisture (Control : 3.8$\pm$5.8%, vs Sample : 15.2$\pm$4.7%) and lowered scabrousness levels (Control : -12.3$\pm$4.4%, vs Sample : -22.0$\pm$5.2%) significantly. However, the levels of sebum did not affected by sample. Conclusions : These result suggest that alcoholic fermentation extract from ovary and rind of pear has moisturizing effect on human skin.
