Photoaging is the main extrinsic aging factor that is induced due to UVB. Many studies have revealed that application of hyaluronic acid to the skin is effective in healing photoaging. However, the effect of hyaluronic acid through oral administration is unclear. The aim of this research was to investigate the effect on skin photoaging after oral administration of hyaluronic acid. During a ten week study, hyaluronic acid was fed to hairless mice, which were illuminated by UV radiation. After ten weeks, wrinkle indicator and histological changes were determined. Compared with the control group, the sample group had a decrease in wrinkle depth, thickness, and number. Especially, the HA 160 mg/kg group had a similar value of wrinkle depth ($19.44{\pm}0.75{\mu}m$), number ($654.00{\pm}98.34$), and thickness ($1.35{\pm}0.08mm$), when compared with the RA (retinoic acid) group ($19.28{\pm}0.95{\mu}m$, $653.57{\pm}83.54$, and $1.34{\pm}0.07mm$ respectively). Also, the treated group showed improved elastosis and decreased collagen degradation resulting from UV irradiation. Thus, we can conclude that hyaluronic acid has a positive effect in improving skin photoaging induced by UV radiation. Hyaluronic acid therefore has the potential to be an ingredient in skin health function foods.

As the aging society progresses and the functional cosmetics market is revitalized we have learned that the functional cosmetics that the silver generation is most interested in are wrinkle-improving products and we are making great efforts to develop functional cosmetics that improve wrinkles. The ingredients are actually making. From the early 2000s when the development of functional cosmetics began to the present the research trends of functional cosmetics for wrinkle improvement were analyzed by analyzing papers on functional cosmetics for wrinkle improvement. Research methods focused on literature search and SIRS paper search keywords. And the cosmetic material that needs to be researched focuses on the anti-aging function among functional cosmetics which is the anti-wrinkle function. The research results show the rapid growth of the Anti-aging market. As the population ages the generation of silver with high purchasing power will expand and a market for expensive anti-aging products and services for a healthy old age will be formed.

Deficiency of collagen regeneration, denaturalization of elastic fibers, and promotion of reactive oxygen species formation are important factors for deterioration of skin function. They induce wrinckle formation and decrease skin elasticity. Vitamin C and its derivatives have been used as cosmetic ingredients for anti-aging effects but their chemical instability has been a major problem. In an attempt to develop a novel anti-aging agent with a improved stability and bioactivity, the anti-wrinkle effect of 3-O-cetyl-L-ascorbic acid (VCCE), a new vitamin C derivative, was investigated in this study. VCCE increased procollagen type-1 synthesis in a dose-dependent manner (149% at 0.002%) in cultured fiboroblasts. Its potent anti-wrinkle effect was confirmed in vivo by analyzing human skin replica by a visiometer and the PRIMOS system. It did not cause any irritation in human patch test. Taken together, our findings suggest that the VCCE has potential benefits applicable to cosmetics for anti-wrinkle effects.

피부 이미지의 여러 가지 특징들 중 주름은 피부의 상태를 판단하는 중요한 요소이다. 따라서 주름을 추적하기 위해 확대경으로 촬영된 원본 이미지에서 질감 대비 증가, 노이즈 제거 등의 전처리 과정을 수행한 후 Watershed 알고리즘을 이용하여 주름을 선분으로 표현하였다. 이렇게 생성된 주름의 깊이, 너비, 길이 등은 피부 분석 시 특징 정보로 이용할 수 있다. 또한 주름과 주름이 연결되어 이루는 다각형을 논문에서는 셀(Cell)이라고 정의하는데 그것의 크기나 개수 같은 정보도 추출할 수 있게 된다. 그러나 주름으로 만들어진 셀들은 실제와 다르게 과분할 되는 경향을 보인다. 과분할 된 셀들은 잘못된 정보를 제공하기 때문에 피부 상태를 판단하는 결과의 정확도를 떨어뜨린다. 본 논문에서는 이러한 문제점을 인지하고 차후 정확한 셀 정보를 획득하기 위한 확장성 측면에서 각 셀들을 개체화시키고 과분할 된 셀을 검출하는 방법을 제안한다.

The reactive oxygen species generated by ultraviolet rays causes various types of cutaneous damage, such as lipid peroxidation and denaturation of the extra-cellular matrix. The accumulation of such damage contributes to skin aging, especially the formation of wrinkles. This study was carried out to develop functional cosmatic by using Oriental herb supercritical extracts (OHSE) for prevention of skin. Effects of OHSE on anti-oxidation, collagenase inhibition and collagen synthesis in normal human fibroblast were investigated. OHSE showed antioxidative activity as high as vitamin C, trolox and DL-penicillamine. Also OHSE showed promotive effect on collagen synthesis and inhibitory effect on collagenase activity. From this results, we conclude that OHSE may have the potential to be conveniently used as an additive in cosmetics for prevention and improvement of skin aging.

목적 : 본 연구는 녹용약침액의 주름 개선 효과에 대하여 여러 가지 in vitro 실험을 통해 확인해 보고자 계획되었다. 방법 : 녹용약침액의 항산화효과를 DPPH(1,1-diphenyl-2-picrylhydrazyl) 자유라디칼 소거법을 이용하여 측정하였고, 또, elastase 억제 효과를 측정하였다. 그리고 녹용약침액이 사람 정상 섬유아세포 HS 68에서 UVB 조사 후 type I procollagen의 생산량 회복에 미치는 효과를 ELISA법을 이용하여 측정하였다. 결과 : 녹용약침액에서 우수한 DPPH 자유라디칼 소거 효과가 관찰되었다. 또한 통계적으로 유의한 elastase 활성 억제 효과를 관찰할 수 있었다. 사람 섬유아세포 HS 68을 이용한 실험에서는 녹용약침액 처치군에서 UVB 조사로 감소된 type I procollagen이 유의하게 회복되는 것이 관찰되었다. 결론 : 본 연구 결과에 의하면, 녹용약침액에는 유효한 주름개선 효과가 있어, 미용약침 소재로 개발할 수 있을 것으로 사료된다.

Skin anti-aging effect of Forsythia viridissima L. extract was evaluated by using antioxidant assay, expression of type I procollagen, and UVA-induced matrix metalloproteinase-1 in human dermal fibroblasts. Matairesinol-rich Forsythia viridissima L. extract was showed the scavenging activity of radicals and reactive oxygen species with the $IC_{50}$ values of $4.50\;{\mu}m/ml$ against 1,1-diphenyl-2-picrylhydrazly radical and $542.43\;{mu}m/ml$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. The type I procollagen was increased 33.76% by treatment with matairesinol-rich Forsythia viridissima L. extract, and UVA-induced MMP-1 was reduced 35.78% in a dose dependent manner. In the human skin irritation test, 2% matairesinol-rich Forsythia viridissima L. extract did not show any adverse effect. Also, the clinical study indicated that a cream group treated with 0.2% matairesinol-rich Forsythia viridissima L. extract significantly reduced skin wrinkles, as compared with a non-treated cream group (p < 0.05). These results suggest that Forsythia viridissima L. extract may be useful as a potential source of functional anti-aging cosmetics.

Wrinkle formation is mainly attributed to the environmental factors such as UV rays, air pollution, smoking and stress etc. Especially, UV rays induce premature skin aging which is characterized by deep wrinkle, leathery dryness etc. Recently, researches on the wrinkle formation and its prevention have been the main theme in cosmetics fields. We have studied the various plant extracts having anti-wrinkle effects and finally showed that Noni (Morinda citrifolia) extracts have the efficacy of promoting the type I collagen synthesis in normal human fibroblast, using PICP assay. We purified one active compound from Noni extracts and identified its structure. It was identified as 6,7-Dimethoxy-2H-1-Benzopyran-2-one; scopoletin by $^1H-NMR,\;^{13}C-NMR,$ IR, Mass analysis. Scopoletin increased collagen synthesis in a dose dependent manner (89.5% at $0.2{\mu}g/mL$). In order to verify the anti-aging effectiveness of the cream containing 3% noni extracsts, we performed the in vivo test with some female volunteers for 12 weeks. It reduced the signs of aging, especially face wrinkles. From these results, we conclude that the noni extracts could be used as an useful anti-wrinkle agent.

Lips have a defect in maintenance of moisture due to their thin layer. As aging progresses, lips lose volume and redness, and become wrinkled. Fat grafting and filler surgery have been used to achieve attractive lips, but little research has been reported to develop better materials to replace the present methods. Recently, a study suggests that the increase of adipocyte number can be enhancing the expansion endogenous fat. In previous study, we identified that the efficacy of Magnolia officinalis bark extract (MOBE) was effective on the induction of adipogenic differentiation. In this study, we confirmed that MOBE enhanced the differentiation of human adipose-derived stem cells on the fat mimic 3D structure built by 3D bioprinting method From further experiments in human, we established a method to quantify the severity of lip wrinkle by measurement of standard deviation of gray value using Image J software. Finally, we found that topical treatment with 1% MOBE formulated lip balm significantly improved the lip wrinkle after using for 12 weeks. In conclusion, these findings suggest that MOBE has great potential, as a cosmetic ingredient, to reduce the lip wrinkle through the effect of promoting adipogenic differentiation.
