Matrix metalloproteinases (MMPs) are known to play an important role in photoaging by mediating the degradation of extracellular matrix proteins. In this study, to develop a n ew anti-aging agent, we investigated the antioxidant activity and the inhibitory effect of Melothria heterophylla extract on expression of MMP-1 in UVA-irradiated human dermal fibroblasts and MMP-1 activity. The M.heterophylla extract was found to scavenge radicals and reactive oxygen species (ROS) with the $SC_{50}$ values of $13{\mu}g/ml$ against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and $20{\mu}g/ml$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. UVA-induced MMP-1 expression was reduced about 80% by $100{\mu}g/ml$ of the M.heterophylla extract but MMP-1 Mrna expression was not inhibited. Therefore, we conclude that the M.heterophylla extract significantly inhibits MMP-1 expression at the protein level. Also, the M.heterophylla extract inhibited MMP-1 activity in a dose dependent manner. From these results, we suggest that the M.heterophylla extract can be used as a new anti-aging agent by antioxidant activity, regulation of UVA-induced MMP-1 production, and inhibition of MMP-1 activity.

In this study, in an attempt to search for functional cosmetic ingredients from higher fungal, we have produced exopolysaccharides (GF-l, approximately carbohydrate 75％, protein 25％) and polysaccharide (GF-2) of mycelium extract, by submerged culture of Grifolafrondosa. For applications in anti-aging cosmetic field, we investigated the diverse biological activities. Antioxidant activity and inhibition of Matrixmetalloproteinases (MMPs) were investigated enzymatic assays by measuring the superoxide scavenging activity using xanthine-xanthine oxidase system and the proteolytic activity of MMPs using EnzChek Collagenase/Gelatinase kits, respectively. GF-l polysacchairde showed inhibition of superoxide radical by 90％ at a concentration of 0.2％ (w/v) and inhibition of collagenase by 45％ at 0.2％ (w/v). GF-2 polysaccharide of mycelium extract also exhibited good antioxidant activity. However, MMPs inhibition activity was relatively lower level compared to GF-l polysaccharides. The treatment of human dermal fibroblast (HDF) with GF-l and GF-2 polysaccharides increased the proliferation of fibroblast by approximately 23-25％ at a concentration of 0.5％ (w/v), also showed collagen synthesis increase in HDF by about 50％ at 0.5％ (w/v) compared to that of untreated control. We also report the moisturizing effects of polysaccharides in cosmetic products (O/W emulation) and its own ingredient, in vitro and in vivo. The GF-1 polysaccharide showed higher moisturizing ability than sodium hyaluronate, which is the most commonly used moisturizers ingredient. These results suggest the GF-l polysaccharide, protein-bound polysaccharide, may be used as an ingredient for new moisturizing and anti-aging cosmeceuticals.

Objectives: Ultraviolet (UV) radiation may cause skin cancer, photo-ageing, erythema, and sunburn. Benzophenone (BP) is commonly used to protect skin from UV radiation. In Korea, sunscreen, sunblock, socalled 'blemish balm' (BB) and 'color correcting' (CC) creams, and foundation may contain from 0.5 to 5% benzophenone in order to protect skin from UV radiation. The purpose of this study is to understand the levels of benzophenone derivatives in urine among a group of university students and identify the contribution of cosmetics use. Methods: Forty volunteers (20 women and 20 men) were asked about skin type, frequency of use of cosmetics, and recognition of related health effects, etc. in a survey. Subjects were divided into several subgroups and were compared for concentration of benzophenone-1 (BP-1) and benzophenone-3 (BP-3). Their urine was pretreated with enzyme hydrolysis and solid phase extraction. Determinations of BP-1 and BP-3 in the urine were made with LC-MS/MS. Results: Among the study subjects, 82.5% used basic cosmetics at least once per day, and 77.5% used sunscreens at least once per day. The concentrations of BP-1 and BP-3 of the males were 4.36 ng/mL and 9.16 ng/mL, respectively. Those of the females were 3.98 ng/mL and 5.07 ng/mL, respectively. The use of cosmetics was positively related to urinary benzophenone levels. Conclusions: BP-1 and BP-3 were widely detected among the university students. Cosmetic use was identified as a potential source. Implications of such exposure deserve further investigation.

Betamethasone propionate, an anti-inflammatory glucocorticosteroid, was detected in cosmetics with no indication on the label of this compound as an ingredient. The product was formulated as a topical spray or shampoo and labeled to contain zinc pyrithione as the active ingredient. A thin-layer chromatographic analysis was carried out on silica gel plates to provide a first indication about the presence of a compound with steroid structure and reactivity; then high-performance liquid chromatography (HPLC) separation allowed the identification of the corticosteroid agent and its quantification. To identify the corticosteroid agent from these commercial samples we collected the fractions suspected to have ketol steroids by prep HPLC and identified the compound as betamethasone propionate by NMR and MS spectrometry. Then we synthesized the standard for the betamethasone 17-propionate and 21-propionate and quantitate the corticosteroids from the sample by HPLC with that standards. By this method we identified the corticosteroid compounds from some commercial cosmetics such as zinc pyrithione sprays. The finding of betamethasone propionate in the products was shown by comparison to an authenticated standard of betamethasone propionate by retention time on reverse-phase HPLC. Two of the tested products contained betamethasone propionate at the levels of 0.005 ${\sim}$ 0.02% and the others were free of betamethasone propionate.

The Chinese cosmetics market is rapidly expanding, but various problems have also emerged, including exaggerated advertisement, lack of accurate information on product usage and the emergence of imitation products. For this reason, cosmetics companies have been making efforts to convince Chinese consumers of their brand authenticity and trust. In particular, Korean cosmetics firms have been using Hallyu stars who are largely popular among Chinese consumers as a means to raise their brand authenticity and trust. The aim of this study was to view Hallyu stars as human brands in the Chinese cosmetics market and verify whether the Chinese consumers' attachment toward Korean celebrities help the consumers perceive the authenticity of the brands advertised by the stars, and whether such brand authenticity affects the Chinese consumers' trust in Korean cosmetics brands. Furthermore, based on the fact that brand authenticity is defined and classified differently according to the type of product, this study observed the authenticity of Korean cosmetics brands from the aspect of product, employee and company based on previous research conducted on cosmetics brand authenticity. To this end, this study surveyed Chinese consumers for a month by using a representative survey website (http://www.sojump.com) that actively shares information related to cosmetics. A total of 394 surveys were used in the empirical analysis. The results of empirical analysis indicated that Chinese consumers' attachment toward Hallyu stars spreads to the Korean cosmetics brands advertised by the celebrities to have a positive effect on the brand authenticity perceived by Chinese consumers, including the authenticity of product, employee and company. Results also showed that the authenticity of Korean cosmetics brands, including product, employee and company, affected Chinese consumers' trust in the brands. The results of this study can provide implications regarding advertising or marketing strategies using Hallyu stars that can be utilized by Korean cosmetics companies to improve brand authenticity and reliability perceived by Chinese consumers in the Chinese cosmetics market, where brand authenticity and reliability are important.

Chitin and chitosan have been almost neglected until 1960's although they second largest biomass on earth. Chitosan is a partially deacetylated chitin and belongs to the class of cationic biopolymers. We investigated the antimicrobial activity of chitosan as natural preservatives in cosmetic products. Antimicrobial activity of chitosan against some microorganisms was investigated. The results indicated that chitosan had an effectiveness against some bacteria. We found that chitosan had minimum inhibitory concentataions as low as 100 ppm to S. aureus ATCC 6538, E. coli ATCC 1634 and P. aeruginosa KCTC 2004. But there was not effects to Asp. Niger ATCC 1374 at 1,000 ppm. Also, formuias preserved with chitosan have been subjected to preservative efficacy tests to some microorganisms. Formla preserved with 0.5% chitosan had an effective antimicrobial activity against the Gram (+) and Gram (-) bacteria but not fungi. It is possible to dertermine the formulas with chitosan, which would be effective to reduce the artificial preservatives.
