For the experiment, to develop new materials for cosmetics, the Celosia cristata L. plant ethanol extract were used for physiological effect and cosmetics application research. The Celosia cristata L. is a Korean traditional variety grown. To investigate the effect of Ethanol extract of Celosia cristata L. on skin care, we measured anti-oxidant activity and anti-aging activity. Celosia cristata L. ethanol extract itself had anti-oxidant activity in a dose-dependent manner in 1-diphenyl-2-picryl-hydrazyl(DPPH) radical scavenging. Ethanol extract had anti-oxidant activity in a dose-dependent manner. Silica dose-dependently increased the intracellular ROS generation in RAW 264.7 cells. Celosia cristata L. ethanol extract inhibited silica-induced intracellular superoxide anion generation and $H_2O_2$ generation and hydro-peroxide generation in RAW 264.7 cells. For anti-aging effects, the hyaluronidase inhibition effects, were relatively strong and they also showed elastase activity inhibition effects, which suggesting the Celosia cristata L. ethanol extract might be used as hydration and anti-wrinkle agents. From the above results, it is referred that Celosia cristata L. ethanol extract appears to have potent anti-oxidant activity and anti-aging activity.

This study aims to prove the changes, development and social background of Korean male cosmetics over the period of 2000-2010. There were total 574 articles written about male make-up and cosmetics in Chosun Daily, Joongang Daily and Donga Daily, which are the top three Korean local daily newspapers in terms of sales revenue for that period. These articles were analyzed together with social background research from various books and daily newspapers. The analysis of articles was divided into different categories; such as foundation cosmetics, color cosmetics, hair, and the social background. It was found that the articles related to foundation cosmetics were written the most, the articles related to male appearance management were second, articles on other items including how to manage the skin being the least. As for the social background of Korean male cosmetics, first of all, a change in social recognition can be pointed out. The traditional understanding of gender roles has changed, men's appearance management has started to be regarded as a competitive talent, and at the same time, the esthetic viewpoint for men also has changed. One example is the newly made popular term, "flower-handsome man", which shows the new trend of favoring males with nice skin. Second, the expansion of mass culture can be pointed out. As consumers can get information and fashion trends easier and faster, the fashion spreads fast, and this has led to the generalization and popularization of the sense of beauty. Third, the development of scientific technology and medical science can be pointed out. Thanks to the progress in those areas. the extension of youthfulness has become possible and the cosmetics industry was also affected greatly, as shown in the market spread of functional products for anti-ageing and wrinkle control as the interest in anti-ageing has grown. There are benefits from the development of scientific technology, but the problem of environmental pollution has appeared due to machinery and industrialization and thus the issue of well-being has been raised. Rising interest in naturalism, pro-environmentalism and organic cosmetics has influenced the cosmetics industry. In addition, the quantity of ultraviolet rays exposed to our skin has increased due to the air pollution caused by the destruction of environment, leading to increased usage of sun block lotion. Lastly, the influence of consumer society and the expansion of consumerism culture can be pointed out. In the modern society, consumption acts not only as the use of products and services but it also has an important role of mediating individuals with others and the society. The market for male cosmetics has been expanding and the number of men putting on make-up has been increasing rapidly. Therefore, this study is meaningful in that the analysis of the mode of change and the social background are an essential process in order to provide a direction for the future market for male cosmetics.

Intermediate-wavelength solar radiation, also known as ultraviolet B (UVB: 290-320 nm) radiation, may cause premature aging and oxidative damage-dependent skin cancer in humans. UVB-induced formation of reactive oxygen species (ROS)-often a consequence of excessive exposure to these rays-could activate matrix metalloproteinases (MMPs) such as MMP-1 and MMP-3. These enzymes break down type I collagen in human fibroblasts. In this study, we assessed the antioxidant and anti-aging effects of ethyl acetate extract of blueberry (EEB). An antioxidant test in blueberries evaluated ROS production using CCD-986sk cells and DPPH assay. In order to evaluate the anti-wrinkle efficacy of blueberries, the MMP-1 production and type 1 procollagen synthesis evaluated and the expression of MMP 1, 3 were tested through Western blot and RT- PCR. EEB exhibited 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and reduced the production of UVB-induced ROS. Also, EEB inhibited UVB-induced processes associated with photoaging and skin cancer, such as reduction in procollagen production and increase in MMP-1 production. More precisely, EEB (50 ㎍/ml) markedly suppressed mRNA and protein levels of MMP-1 and -3. The anti-aging effects are attributable to the antioxidant activity of EEB. These findings indicate that EEB has a protective effect against UVB-induced aging in human fibroblast cells by regulating the levels of type-1 procollagen, MMP-1, and MMP-3.

The purpose of this study was to investigate the antiaging effect in the fibroblasts by using the extracts and fractions of Nymphoides peltata for the development of new functional cosmetic materials. The anti-aging effects of the extracts and fractions of N. peltata were measured using CCD-986sk cells. Ethyl aceate (EA) fraction inhibited UVB-induced reactive oxygen species expression by more than 50%, and n-butyl alcohol (BuOH) fraction increased expression of pro-collagen mRNA by more than 50% at $25{\mu}g/mL$. In addition, EA and BuOH fractions inhibited MMP-1 protein and mRNA expression in a concentration-dependent manner, BuOH fraction inhibited MMP-1 mRNA expression by more than 40% at $10{\mu}g/mL$. Especially, the high efficacy of EA and BuOH of the N. peltata was confirmed. Therefore, the EA and BuOH of N. peltata are expected to be useful as anti-aging materials in cosmetics field.

In this study, various plant extracts were screened for the effective and safe skin care ingredient according to the antioxidant activity assay guidelines. We selected an optimized combination herbal extract, Charmzone extract (CZE), which composed of Nelumbo nucifera leaves, Saururus chinensis and Orostachys japonica. CZE exerted free radical scavenging activity. It reduced reactive oxygen species formation and increased total antioxidant capacities in human keratinocyte (HaCaT) and normal human dermal fibroblasts (NHDF). CZE also leaded procollagen type 1 secretion in NHDF and decreased cellular melanin contents in B16F10. The production of nitric oxide was decreased by CZE in lipopolysaccharide-stimulated RAW264.7 in a dose dependent manner. Therefore, it is concluded that CZE can be applied for naturally derived anti-aging functional skin care ingredient for anti-oxidation, wrinkle enhancement, whitening, anti-inflammation and wound healing of skin.

Botulinum toxin type A (BoNT/A) has been proven to be a safe and effective treatment for wrinkles in human. As well as the anti-wrinkle effects, the anti-pruritic effect of BoNT/A has been revealed from several researches for new therapy. The aim of this study was to investigate the anti-pruritic effect of BoNT/A against histamine-induced pruritus on canine skin. Five clinically healthy beagles were included in the study. All dogs were received 0.05 ml (5 Unit) of BoNT/A on the right dorsal thoracic region as an experiment and the same volume of saline solution was injected on the left dorsal thoracic region as a control, respectively. Intradermal histamine injections were performed four times (before treatment and days 1, 3 and 7 after BoNT/A injection). The severity of pruritus, the diameter and thickness of wheal, the erythema index and cutaneous temperature were assessed. The severity of pruritus was reduced on BoNT/A treated sides, compared with saline treated sides (p < 0.05). BoNT/A decreased wheal size, in both diameter and thickness (p < 0.05). Although, erythema index of both sides were increased after first histamine injection, BoNT/A treated sides showed the low-value as compared with saline treated sides. Cutaneous temperature was decreased significantly on BoNT/A treated sides. These results indicates that BoNT/A reduce histamine-induced pruritus on canine skin and suggested a possibility of application of BoNT/A for local intractable dermatologic problem in dogs.

Alpha hydroxy acid (AHA) includes a group of organic acids found in natural foods such as sugarcane (glycolic acid), milk (lactic acid), apples (malic acid) and oranges (citric acid). Earlier studies demonstrated the effect of AHAs on the skin by diminishing the adhesiveness of the corneal layer and increasing the viable epidermal thickness. Recent data suggest that AHAs have some effects on the dermal component of skin and even affect the aging process of the skin. A previous study revealed increased collagen production by treatment with glycolic acid among AHAs in vitro. However, the mechanism of the regulation of collagen production by glycolic acid was unclear. In present study, we tried to demonstrate the effect of glycolic acid on human dermal fibroblasts and to unveil the mechanism of regulation of collagen production by glycolic acid in human dermal fibroblasts: proliferation of fibroblasts and collagen synthesis and degradation by collagenases in fibroblasts. Our results suggested that glycolic acid had no effect on proliferation and cytotoxicity of adult human dermal fibroblasts. However, glycolic acid not only induced the increase of the collagen synthesis in human dermal fibroblasts at lower concentration than 0.1 % but also inhibited MMP-2 activity of human dermal fibroblast in the range between 0.01 and 0.4% and MMP-9 activity of human dermal fibroblast in the range between 0.06 and 0.09%. In summary, our results suggest that glycolic acid may increase wrinkle reduction partially by both increase in collagen synthesis and decrease in collagen degradation.

Korean Ginseng is a medicinal herb which grows naturally in korea. an ancient country situated in north-eastern Asia. Its medical use was already well known to herb doctors in this region about five thousand years ago since the effectiveness of korean ginseng has been recognized through practical use for a long time. Korean Ginseng has always been regarded as a devine cure. The name "Ginseng" can be found in various medicinal books. many of which were written as early as B.C. 100. In the records of many chinese medical books. dating from the inception of publishing, it was noted that Korean Ginseng was of the highest level of quality. Korean Ginseng originally grew in the mountains of korea. However, this wild Korean Ginseng(js called SANSAM) could not meet the ever-increasing demands. and from the 16th century. it has been cultivated on farms for mass processing and supplying in korea(js called INSAM). It was already recognized in korea a long time ago(B.C. 57 - A.D. 668) that Korean Ginseng possessed the qualities of panacea, tonic and rejuvenator, and had other medicinal properties as well. The effectiveness of Korean Ginseng is widely recognized among south-eastern Asians as well as Chinese. As its effect has been proved scientifically. Korean Ginseng is now becoming the ginseng for all human beings in the world. Korean ginseng is differently called according to processing method. Dried thing is Insam(white ginseng), boiled or steamed is Hongsam(red ginseng). 장뇌삼(long headed ginseng) is artificially grown in the mountain no in field for a long time. So the body is thin and some long. but ingredients are concentrated. Korean wild ginseng(SANSAM) is rare in these days but we developed cosmetic ingredient. The scientific name of Korean Ginseng is Panax Ginseng. It has acknowledge as a natural mysterious cure among the notheastern peoples. because of its broad medicinal application. The origin of the word" Panax" derived from panacea. a Greek word meaning cure-all. According to the classification method of herb medicines in the Chinese medicinal book. "God-Farmer Materia Medica(A.D. 483-496) korean Ginseng was described as the superlative drug: panacea. tonic and rejuvenator. We studied skin immunological effect. collagen synthesis. cell growth and whitening effect of SANSAM extract. IN cosmetics.. SANSAM extract had skin fibroblast cell growth effect. recover damaged skin in the sun and protect fine wrinkle. Also. In hair product.. inhibits hairless, white hair.its hairless, white hair.

Oriental herbal liquor (Yakju) is a type of Korean traditional alcoholic beverage that uses Nuruk and oriental herbs for fermentation. The purpose of this study was to develop cosmetic ingredients using Jubak, which is a by-product of alcoholic fermentation of oriental herbal liquor. To investigate antioxidant, whitening, and anti-aging effects of Jubak, we prepared extract of Jubak and its solvent fractions. Ethyl acetate fraction (KSD E4-3) showed the most prominent free radical [1,1-diphenyl-2-picrylhydrazyl (DPPH)] scavenging activity ($SC_{50}$: 0.75 mg/mL). KSD E4-3 significantly inhibited in vitro mushroom tyrosinase activity ($IC_{50}$: 0.82 mg/mL) and reduced the melanin contents in mouse melanoma melanocyte, B16F10 cells. KSD E4-3 down-regulated protein expression of tyrosinase related proteins (TRP)-1, -2, which play key roles in melanogenesis. For anti-aging effects, inhibition of matrix metalloproteinase (MMPs) expression was evaluated using human keratinocyte, HaCaT cells. Treatment of HaCaT cells with KSD E4-3 reduced expression of MMP-1, -2, -9 and inhibited proteolytic activities of MMP-2, -9. These results suggest that KSD E4-3 induces down-regulation of cellular melanogenesis and protects against photoaging induced by UVB-induced damage. Thus KSD E4-3 could potentially be a valuable cosmetic ingredient.
