Aging of the face is mainly related to the features that are sagging or loss of elasticity of the skin by reducing the volume around the eyes or cheek. Intrinsic aging can be seen to cause thinner dermis, reduction of extracellular matrix and subcutaneous fat. This study was carried out to investigate the skin volume augmentation and anti-wrinkle effects of Tribulus terrestris fruit extract. Skin anti-aging effect of Tribulus terrestris fruit extract was evaluated by using lipid accumulation, expressin of type I procollagen and elastin in preadipocytes and human dermal fibroblasts. Tribulus terrestris fruit extract augmented preadipocytes differentiation about 56% at 100 µg/mL. The type I procollagen and elastin were increased about 35% and 25% by treatment 20% Tribulus terrestris fruit extract, respectively. The clinical study also showed that skin sagging, skin elasticity, and dermal density improved without adverse effect following 4 week application of cream containing 2% Tribulus terrestris fruit extract. We suggest that Tribulus terrestris fruit extract can have the good possibility as skin volume augmenting, skin elasticity and wrinkle improving agent.

In this study, we created pupal stage extracts of Apis mellifera L. drones for use in cosmetic materials. The effect of the drone pupae extract (DPE) on HDF cells was assessed for analysis of anti-wrinkle activity by collagen or collagenase gene expression, and the skin-lightening effect was studied by in vitro tyrosinase inhibition and B16F10 melanoma assay; the two cells were found to be non-cellular when the concentration of DPE was 100 ㎍/ml. Albutin concentration (positive control) in the whitening test was set at a capacity of 100 ug/ml and m-melanocyte stimulating hormone (α-MSH). A melanin-producing induction material was set at a concentration of 100 nM, and the expression of collagen type I and MMP1 collagenase was measured using HDF cells. MMP1 expression was seen to reduce in a concentration-dependent manner in treatment with DPE. Inhibiting melanin generation with B16F12 cells indicated a tendency to decrease in the DPE treatment group. Both L-Tyrosine and L-DOPA as DPE were used in an in vitro tyrosinase induction test to demonstrate the effects of tyrosinase suppression on concentrations. The higher the concentration of DPE, the greater the wrinkle reduction and whitening effect. In conclusion, it was found that DPE is an effective smoothing and whitening material by increasing collagen generation and inhibiting collagenase expression and reducing melanin production.

Objectives : Recently, Thread Embedding Acupucnture (TEA) targeting under dermis became known to be effective for facial wrinkles and folds; its practice has begun in clinics. The introduction of a new form of TEA is continuing, and 'Volume TEA' is introduced recently. Therefore, we would like to report on the improvement of facial wrinkles by using the recently introduced 'volume TEA'. Methods : We reviewed the medical records of three patients who received 'Volume TEA' treatment at a Korean medical clinic, the photographs taken before and after the procedure were corrected using a Photoshop program and the length of the each wrinkles and folds were measured. Results : The length of wrinkles measured in all three cases decreased. Especially, the decrease of the length of the nasolabial folds was obvious. In case 1, the length of the nasolabial folds of 177mm and 97mm were reduced to 94mm and 63mm, respectively. In the case 2, the length of the nasolabial folds of 155mm and 155mm were reduced to 0mm and 70mm, respectively, after the procedure. In case 3, the length of the nasolabial folds of 170mm and 50mm decreased to 38mm and 37mm after the procedure, respectively. Conclusions : At present, it seems that the ongoing accumulation of relevant studies on the efficacy and safety of wrinkle and folds of TEA seems necessary. This study also has some significance in the level of case report.

산업화 과정에 방출된 할로겐 화합물 및 프레온 가스가 오존층을 파괴하면서 많은 양의 자외선이 지표에 도달하여 생태계에 적지 않은 영향을 끼치고 있다. 자외선은 살균, 소독작용 및 Vitamin D 합성을 위해 생명체에 필수적이지만 과다할 경우 색소침착, 피부노화, 피부암 발생, 백내장의 증가, 면역기능저하 등의 피해를 준다. 자외선은 파장 영역에 따라 UV-A(장파장 자외선), UV-B(중파장 자외선)및 UV-C(단파장 자외선)으로 나뉜다. 이 중 인체에 가장 유해한 것으로 알려진 단파장의 UV-C는 파장이 짧아 침투력이 미약해 오존층과 성층권에서 대부분 흡수되므로 생물학적으로 큰 의미는 없다. 그러나 자외선 중 UV-B와 UV-A 영역의 자외선은 인체에 영향을 가장 많이 미치므로 이들 영역의 자외선을 차단하는 것이 필요하다. Vitamin C는 아스코르브산(ascorbic acid)이라고도 불리며 미백효과, 주름 개선, 자외선 차단 및 항산화 작용을 하지만 섬유가공 시 Vitamin C는 쉽게 산화되며 세탁 내구성이 떨어지기 때문에 가교제를 필요로 한다. Vitamin C를 이용하여 자외선 차단성 섬유제품을 개발하기 위해, 포름알데히드를 유리하지 않는 폴리카르복시산 가교제 중 하나인 Citric Acid(CA)를 사용하여 고온에서 면직물에 처리했을 때 에스테르 형 가교를 형성하여 내세탁성을 가질 수 있었다. 자외선 차단 효과를 알아보기 위하여 KS K 0850 섬유제품의 자외선 차단율 및 차단지수 시험방법으로 평가하였다.

This paper has shown the experimental results about the physiological activities of water-, ethanol-, ethyl acetate-soluble fractions from ethanolic extracts of leaves, stems and roots of Cudrania tricuspidata on the skin, which has been used for a long time as a traditional herb medicine in Korea and China. The effects of these fractions on the secretion of nitric oxide and cytokines from macrophage(RAW 264.7 cell) exhibited that the ethyl acetate and water fractions from leaves inhibited the release of nitric oxide, all fractions inhibited thoses of inflammatory cytokine $IL-1{\alpha}$, and the ethyl acetate fractions of leaves, stems and roots inhibited thoses of inflammatory cytokine IL-6. The only ethylacetate fraction of leaves demonstrated significantly the reduction of melanin synthesis in melanoma cells. In order to evaluate the efficacy of collagen synthesis, the treatment with extracts on the human normal fibroblast cell(CCD-986sk cell) resulted in finding that the water fractions of leaves, stems and roots and the ethanol fractions of leaves and stems showed the increased synthesis of collagen.
