  • Skin is the largest organ that protects the body from the external environmental factors such as smog, cigarette smoke, UV. Protective skin barrier is composed with keratinizational keratinocytes and intercellular lipids such as ceramides, cholesterols and fatty acids combined by the lamellar liquid crystal structure. In this research, we confirmed that the Jeju wild ginseng (JWG) extracts dose-dependently increased the expression of serine-palmitoyltransferase (SPT) protein which is associated with ceramide biosynthesis. In addition, emulsion containing 5% JWG extract was applied on skin of human volunteers for 2 weeks and then significantly reduced transepidermal water loss (TEWL) compared to that of control group. As a results, JWG extract increased the biosynthesis of ceramides that is the key components of the skin lipid through enhancing expression of SPT. In addition, JWG extract reduced TEWL resulting in improvement of skin barrier function. In this context, we suggest that JWG extract could be used as a skin barrier enhancer and moisturing agents in cosmetic fileds.

  • To evaluate the ability of Dongchongxiacao ($Paecilomyces$ $japonica$) extract (PJE) to protect the skin from photodamage, the gross and microscopic changes in the skin of hairless mice and PJE-treated mice exposed chronically to ultraviolet (UV) were examined. The skin of the UV-irradiated mice showed characteristic signs of photoaging, such as deep wrinkles across the back. PJE-treated mice showed a significantly decreased wrinkling score. By the 22nd week, 88.9% (i.p. with saline) or 44.4% (topical administration with cream base) of the UV-irradiated mice developed at least one tumor. PJE delayed tumor onset significantly. PJE (i.p.) was also effective in reducing the occurrence of UV radiation-induced skin tumors and reduced the number of tumors per mouse. After 22 weeks of treatment, 80.0% (i.p.) and 75.0% (topical) of the mice treated with PJE were tumor-free. Tumor multiplicity was reduced by 96.2% (i.p.) in the PJE treated groups. It is noted that skin that is chronically exposed to UV is subject to photoaging and photocarcinogenesis and regular use of PJE would prevent these photodamaging effects of UV.

  • ln this study, natural extracts extracted from cypress sapiens, a natural material, were investigated as materials that could protect skin aging caused by ultraviolet rays, and experiments were conducted on the synthesis of filaggrins that make up the natural moisturizing factor of the skin, the synthesis of pro-colagen, a fibrous protein, which plays an important role in moisturizing the dermis, and elastin, which is an enzyme that decomposes collagen. As a result, cypress ethanol extract (COE) was a dependent inhibitor to collagenase and elastase, inhibiting the synthesis of filaggrin and the expression of MMP-1 for exfoliated cells damaged by ultraviolet rays. Therefore, it is estimated that ethanol extract will have the effect of delaying wrinkles and as a functional cosmetic material that inhibits skin aging convergence. Based on this study, we would like to further study the mechanism of the synthesis of filaggrin on the suppression of expression of MMP, which is the anti-wrinkle effect.

  • 자유라디칼은 반응성이 커서 세포의 구성 물질인 단백질, 지질, 당, DNA등과 반응하여 세포 및 조직을 손상시킴으로서 노화를 가져온다. 이러한 자유라디칼들은 자외선, 일반 대사, 스트레스, 질병, 흡연 등에 의해 생성되고 특히, 활성 산소 종인 hydroxyl radical, superoxide radical, lipid peroxide radical등은 피부 노화를 발생시키는 원인이 된다. 따라서 본 연구에서는 한방 식물로부터 유해한 활성 산소종을 소거하는 활성을 가진 물질을 기 위해 1차 스크리닝 하였고, 이중 육두구, 관중, 초두구, 빈랑, 금은화, 포공영, 우롱차, 황금, 녹차 추출물이 효과가 높게 나타났으며, 그중 초두구와 빈랑 90% 메탄올 추출물에서 가장 우수한 소거 활성을 나타냄으로써 이 추출물에 대하여 자유라디칼 소거 활성에 대하여 여러 가지 생물학적 활성을 조사하였다. 초두구와 빈랑추출물에 대한 hydroxyl radical, superoxide radical, lipid peroxide radical을 소거하는 활성을 핵산, 클로로포름, 에틸아세테이트, 물층으로 분획하여 조사한 결과 에틸아세테이트층에서 가장 우수한 활성을 보였다. 에틸아세테이트 분획에 대한 lipid peroxide radical 소거에 있어서 빈랑 추출물이 $IC_{50}$/ 값 50 $\mu\textrm{g}$/ml, 초두구 추출물은 $IC_{50}$/ 값 59 $\mu\textrm{g}$/ml로서 기준물질로 사용되는 vitamic C (120 $\mu\textrm{g}$/ml)나 butylated hydroxyl toluene (80 $\mu\textrm{g}$/ml) 보다 더 우수한 소거 효과를 보여주었고, hydroxyl radical을 소거하는 능력은 25 $\mu\textrm{g}$/ml와 150 $\mu\textrm{g}$/ml로 hydroxyl radical의 소거 능이 좋은 vitamin C (180 $\mu\textrm{g}$/ml) 보다 뛰어난 소거 활성을 나타내었다. Superoxide radical을 소거하는 효과는 초두구 추출물의 $IC_{50}$/ 값 10 $\mu\textrm{g}$/ml, 빈랑 추출물이 15 $\mu\textrm{g}$/ml을 나타냈고, 이는 기준 물질인 vitamin C (35 $\mu\textrm{g}$/ml)보다 좋은 소거 활성을 보여주었으며, gallic acid 9 $\mu\textrm{g}$/ml과 유사한 효과를 나타내었다. 사람 섬유아세포를 배양하여 hydroxyl radical과 superoxide radical를 발생시킨 후 초두구와 빈랑 추출물의 세포 보호 효과를 실험한 결과 25 $\mu\textrm{g}$/ml의 농도로 처리하였을 때 각각 85% 이상의 우수한 세포 보호 효과를 나타내었다. 초두구로부터는 자유라디칼 소거 활성이 있는 물질을 분리하기 위하여 분획한 후 가장 높은 소거 활성을 보인 에틸아세테이트 층에 대하여 silica column chromatography, preparative TLC를 수행하였다. 초두구로부터 분리된 물질은 HPLC를 이용한 분리에서 phenol성 물질인 gallic acid와 동일한 retention time을 보여줌으로써 초두구로부터 분리된 물질은 gallic acid와 유사한 phenol성 물질이거나 그의 유도체일 것으로 추측된다. 따라서, 초두구와 빈랑 추출물은 피부 노화의 주요인이 되고 있는 lipid radical, hydroxyl radical, superoxide radical을 소거하는 활성이 뛰어나 자유라디칼에 의하여 발생되는 피부노화를 방지할수 있는 물질로서의 효과가 기대된다.가 기대된다.

  • Wrinkle formation and dryness are the most well-known symptoms of skin aging. This study investigated skin anti-aging and moisturizing effects of Mugunghwa (Hibiscus syriacus L.), the national flower of Korea. The effect of H. syriacus L. flower extract was examined in skin cells originating from humans in vitro and in hairless mice exposed to UVB in vivo. The in vivo study results showed that skin hydration-related factors such as involucrin, filaggrin, HAS1, HYAL1, and matrix metalloproteinase-I (a primary skin photoaging factor) were regulated by H. syriacus L. Additionally, epidermal thickness and collagen disruption, which resulted in wrinkle formation and skin dryness, were ameliorated by oral administration of H. syriacus L. These results indicate that H. syriacus L. flowers can play important roles in preventing aging and promoting skin moisturizing.

  • The study studied dermal protection and crease improvement from the sunlight of the lipid extract and narinjin. Sunlight was investigated in HR-1 (motherless mice) to identify changes in epithelial thickness and changes in collagen fibers, which account for around 90% of dermis, as the inhibitory efficacy of collagenase dissolving collagen also plays an important role in wrinkles. The experiment was validated using narinjin and jisil extract. First: The components of jisil and narinjin were analyzed. Second, antioxidant capabilities were confirmed with DPPH. Third: The inhibitory activity of collagen was measured. Studies have shown that the skin's upper skin thickness suppression of dermal extracts and narinzine has increased and that collagen thicknesses and wrinkles have decreased significantly compared to controls.

  • In the present study, we investigated the protective effect of various grain methanolic extracts against UVB-induced photo-aging in human skin fibroblasts. Various grain methanolic extracts were evaluated for their antioxidant compounds and activities. 2,2-Ddiphenyl-1-picryhydrazyl radical (DPPH) and ABTS 2,2-azino-bris-(3-ethylbenzoth iazoline-6-sulphonic acid) radical cation scavenging activities have been used to measure the relative antioxidant activities of extracts from grains. The content of total polyphenolics in the extracts were evaluated using spectrophotometric methods. Human skin fibroblast (Hs68) cells were pretreated with various grain methanolic extracts ($25{\mu}g/mL$). Skin toxicity was simulated by exposing the cells to UVB ($30mJ/cm^2$) irradiation. In response to the UVB-irradiation, an increased amount of matrix metallo-proteinases (MMPs) release was observed, whereas pretreatment of various grain methanolic extracts significantly inhibited the production of MMP-1 in Hs68 cells. We also found that pretreatment of the extracts significantly decreased UVB-induced reactive oxygen species and significantly increased total collagen content in Hs68 cells. These results provide that grains could be regarded as a potential ingredient in natural cosmetics, used for UVB protection.

  • Objectives: The present study is to observe the skin-regeneration, anti-wrinkle, whitening and skin moisturizing effects of Cheongsangbangpung-tang (CSBPT) with cytotoxicity. Methods: In the present study, cytotoxicity of CSBPT lyophilized aqueous extracts (yield=18.71%) was experimented against human normal fibroblast cells and B16F10 murine melanoma cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium Bromide (MTT) assay, and skin regeneration and anti-wrinkle effects were also showed through the assay of collagen type I synthesis by an enzyme immunoassay (EIA) kit as comparing with transforming growth factor (TGF)-${\beta}1$, hyaluronidase, collagenase and matrix metalloproteinase (MMP)-1 inhibitory assays as comparing with oleanolic acid (OA), and elastase inhibitory effects as comparing with phosphoramidon disodium salt (PP). In addition, whitening effects of CSBPT were observed by tyrosinase inhibitory assay and melanin formation test in B16/F10 melanoma cells as comparing with arbutin, and skin moisturizing effects were measured through mouse skin water contents test, respectively. Results: No CSBPT treatment related cytotoxic effects were demonstrated against human normal fibroblast cells and B16/F10 murine melanoma cells. CSBPT concentration-dependent increased collagen type I synthesis at human normal fibroblast cells. It also effectively suspreessed hyaluronidase, collagenase, elastase and MMP-1 activities, which were enzymes that related to declining of ECM and formation of wrinkle. CSBPT supressed B16/F10 melanoma cells's melanin productions with tyrosinase activity, which was an enzyme connected with melanin formation, and dose-dependent and significant increases of skin water contents were detected in CSBPT treated mouse skin as compared with vehicle control skins. Conclusions: CSBPT showed favorable and enough skin regeneration, anti-wrinkle, whitening and skin moisturizing effects at least in a condition of this experiment. However, more detail mechanism and in vivo skin protective efficacy studies should be conducted in future with the screening of the biological active compounds in individual herbs of Cheongsangbangpung-tang.

  • Anoectochilus formosanus, commonly known as "Jewel Orchids", which has been used in traditional folk medicines for feber, pain, and diseases of the lung and liver in Taiwan. We artificially cultured Anoectochilus formosanus plantlet by using the bioreactor culture system for this study from Anoectochilus formosanus. Previously, several studies have been reported on pharmacological activities of lipid-metabolism, hepatoprotective activity, anti-tumor activity and immuno-stimulating effects but other efficacy were not well known as a cosmetic ingredient for skin care. In this study, we investigated the effect of melanogenesis in B16 mouse melanoma cells and lipid droplet accumulation in 3T3-L1 preadipocytes about Anoectochilus formosanus plantlet extract. We report that Anoectochilus formosanus plantlet extract inhibits the cytoplasmic lipid droplet accumulation through adipogenic differentiation of preadipocytes as well as inhibition of tyorsinase activity and melanogenesis. As a result, our findings indicate that Anoectochilus formosanus plantlet extract may be the potential natural ingredient for whitening and slimming cosmetic products.
