  • 본 연구는 토마토 추출물의 주방세제 유도성 건성피부에 대한 효능을 실험쥐에 식이방법과 피부도포방법으로 처리하여 확인하였다. 약 3주간의 주방세제 처리에 의한 건성 증후는 홍반의 심각한 상태를 나타내는 4정도의 visual scoring이 모든 군에서 확인되었다. 그러나 약 1주간의 토마토추출물의 식이와 피부도포를 통해 상당히 완화되거나 정상 피부에 가까운 0.7-1.0정도의 visual scoring이 확인되었다. 또한 광학현미경을 통해 건성의 또 다른 증후인 과각화 현상이 토마토추출물의 피부도포와 식이로 현저히 감소하는 것으로 확인되었다. 이러한 토마토추출물에 의한 건선성 증후의 완화는 피부 단백질 함량의 양적 변화를 유도하는 것으로 확인되어 토마토추출물의 건선성 피부의 예방과 개선에 주요한 기전으로 이해된다.

  • Recently inside nano liposome particles or nano-emulsions which contain tough-melting physiology activity materials or the coefficient of low organism utilization promote the coefficient of organism utilization, so this part has been studied a lot because they can absorb selectly cosmetics, specially physiology activity materials, into the skin. Also, in particle size, cells interstitial lipid interval are 30~50nm, so nano-emulsions that the size is similar to 30~50 nm are made to study for absorbing quickly into the skin. And transparent skin which contains oils in common skin lotion dosage form has become the center of public interest. The used nano-emulsions in this study were unsaturated lecithin/co-surfactant! ethanol/ oil / water. And polysorbate 20/ polysorbate 80/ Dicetyl phosphate/hydrogenated .caster oil/ isoceteth-20/SLS were used in co-surfactant. The used oils were cyclomethicone and caprylic/capric triglyceride. The manufacturing process was that microfluidizer was fixed in 1000bar and transit times were changed from 1 to 10 times. From transparency and particle size, the transparency sequence was SLS> polysorbate 20= polysorbate 80> isoceteth-20> dicetyl phosphate >hydrogenated caster oil and the particle size was small. Specially cyclomethicone nano-emulsions, when we made unsaturated lecithin /SLS /ethanol/water/cyclomethicone, cyclomethicone 5% was good for transparency. And 20% of this was used for making transparent skin toner in common skin dosage form.

  • Tea flavonoids and polyphenols are well known for their extraordinary antioxidant activity which is considered important for anti-aging processes in animals. This study evaluated the anti-wrinkle effects of three different kinds of tea (Camellia sinensis) water extracts (CSWEs) including green, white, and black teas using a photoaged hairless mouse model. Data showed that the CSWE-treatment greatly improved skin conditions of mice suffering from UVB-induced photoaging, based on the parameters including the skin erythema index, moisture capacity, and transepidermal water loss. In addition, the wrinkle measurement and image analysis of skin replicas indicated that CSWEs remarkably inhibited wrinkle formation. In histological examination, the CSWE-treated mice exhibited diminished epidermal thickness and increased collagen and elastic fiber content, key signatures for skin restoration. Furthermore, the reduced expression of MMP-3, a collagen-degradative enzyme, was observed in the skin of CSWE-treated animals. Interestingly, comparative data between green, white, and black tea indicated that the anti-wrinkle activity of white tea and black tea is equally greater than that of green tea. Taken together, these data clearly demonstrated that CSWEs could be used as an effective anti-wrinkle agent in photoaged animal skin, implying their extended uses in therapeutics.

  • Chronic ultraviolet (UV) radiation causes photoaging, which represents skin damage, disrupts skin barrier function, and promotes wrinkle formation. We investigated that the polysaccharide extract of an edible basidiomycetous white jelly mushroom, Tremella fuciformis, (TF-Glucan®) exhibited statistically photoprotective activity by inhibiting matrix metalloproteases (MMPs) and increasing collagen synthesis, and an anti-inflammatory activity by inhibiting nitric oxide and pro-inflammatory cytokines at the concentrations of less than 1000 ㎍/ml, which is not cytotoxic (p < 0.05). Additionally, TF-Glucan® increased the expression of involucrin and filaggrin to prevent the disruption of UVB-induced barrier function (p < 0.05). TF-Glucan® was assessed as a safe material by the human primary skin irritation (1, 3, 5%), human repeated insult patch test (no sensitization at 5%), 3T3 NRU phototoxicity assay (no phototoxicity, PIF < 2, MPE < 0.1), eye irritation test test by BCOP (no category, IVIS ≤ 3) and local lymph node assay (negative at 10, 25, 50%) for identifying potential skin sensitizing. These results suggest that TF-Glucan® may be useful as an anti-photoaging ingredient for developing cosmeceuticals.

  • 나이를 먹으면 피부의 구조와 생리적 기능이 계속적인 감퇴를 일으켜서 노화된다. 외적요인에 의한 노화는 장기간에 걸친 자외선의 노출로 인한 광노화와 바람, 열, 담배 등이 원인으로 내인성 노화를 촉진시키거나 그 자체도 피부노화를 유발한다. 팔미토일 올리고 펩타이드 또는 세라마이드 올리고 펩타이드는 콜라겐 생산을 자극함으로써 피부의 상층부를 재생하며 아세틸 헥사펩타이드는 피하근육과 피부를 유연하게 하여 주름을 완화하는 성분으로 보톡스 대체 항주름 성분으로 대표적인 고기능성 뷰티성분이다. 대조군과 아세틸 헥사펩타이드 함유 7%, 14%, 20% 성분을 실험 군 A, B, C로 나눠서 주름의 변화, 모공의 변화, 수분량 변화, 과각질의 변화를 분석하였다. 아세틸 헥사펩타이드 함유 성분 분석 결과 통계적으로 주름과 모공, 수분에는 대조군에 비해 영향을 준 것으로 보이며, 과각질의 제거에서는 대조군과 실험군의 값에서 비슷한 결과를 얻을 수 있어 피시험자의 자가 평가의 만족도에서 주름과 모공, 수분에는 대조군에 비해 영향을 준 것으로 보이며, 과각질의 제거에서는 대조군과 실험군의 값에서 비슷한 결과를 얻었다.

  • This study action drama TV drama 'Ya-ha'(夜叉) the actual work practices of the pre-consultation stage through the Writers, Producer, Art directors and in consultation with the opinion of the character set the record of the contents and character changes over time in accordance with characters makeup the design elements were analyzed. The methods of study was used local and abroad related books, studies, publications and cases and the subjects were limited to be four male make up characters in drama 'Ya-cha'. As a result, TV action drama 'Ya-cha' make up design elements and representation techniques were classified as description of skin tone, wound, the shape of eyebrows, hair type, shape of beard and materials and carried out an important role in the character representation. First, presentation techniques changed skin tones depending on character and position and described wound shape as expression technique and materials were analyzed. Second, the shape of eyebrows was based on the physiognomy of the form. And hair type changed volume, thickness, length and texture depending on character. Third, shape of beard is expressed different kinds of volume, thickness, length and texture depending on character. There fore, that systematization of the make-up design elements is useful to express stable characters and make drama for make up in various image genres.
