We investigated characterization as cosmetic substances of chestnut inner skin extracts with in vitro antioxidant activity. Total phenolics of various extracts from chestnut inner skin were the highest 60% methanol (164.82 mg/g), and ethyl acetate fractions (191.14 mg/g). We found that the both samples from chestnut inner skin dose-dependently increased in vitro antioxidant activities (DPPH radical scavenging activity and inhibition of lipid peroxidation). In addition, the both samples also showed a strong UV absorption in the range of UV-B (290-320 nm). Especially the 60% ethanol extracts presented higher inhibitory effect on elastase (46.40% at $100{\mu}g/mL$) than that of the ethyl acetate fractions, so that it showed in vitro anti-wrinkle activity. Finally, the 60% methanol extracts and ethyl acetate fractions showed anti-bacterial activity against skin pathogenic bacteria. Consequently, these results suggest that the chestnut inner skin can be used for cosmetic industry.

This study attempted to investigate the influence of a beauty influencer's characteristics on makeup behavior and color cosmetics purchase intention against young female consumers in their 20-30s, who are a primary target for beauty influencer marketing. It aimed to provide basic data which are helpful in promoting marketing and expanding markets for color cosmetics through beauty influencers. For this, a questionnaire survey was conducted. Among a total of 563 questionnaires distributed across Seoul and capital region, 531 copies were used for final analysis, and the results found the followings: In terms of age, factors affecting beauty influencers' characteristics differed depending on reliability and expertise. Specifically, reliability and communicative competence had a positive effect(+) on all makeup behavior while expertise revealed a positive influence on base makeup only. In color cosmetics purchase intention, a positive effect was observed in reliability, communicative competence and attractiveness. In particular, reliability showed the largest influence. Therefore, there should be continued efforts to maintain a long-term relationship with consumers through communication based on beauty influencers' characteristics and by delivering more diverse makeup and color cosmetics-related information in an open and honest fashion.

The antioxidant activities of 6 solvent extracts of Artemisia capillaris were evaluated in a dintroflurobenzen (DNFB)-induced allergic mouse model. In vitro antioxidant activities were determined using DPPH and the FRAP test. Methanol (DPPH: 85.87%, FRAP: 1.772) and $dH_2O$ (DPPH: 60.69%, FRAP: 3.185) extracts showed the highest antioxidant activities compared with other solvents (ethyl acetate 41.81%, 0.407, hexane 8.37%, 0.328, etc.). In addition, we tested atopic dermatitis (AD)-like skin lesions in mice treated with DNFB. The methanol extract of A. capillaris on the AD-like skin lesions in DNFB-induced atopy inhibited ear thickness increases (47%) and the skin lesions (45%) compared with a positive control (methanol). The results suggest that they have potential as natural antioxidants and allergy-improving substances and that they may be valuable materials in the functional food or cosmeceutical industry.

소엽(Perilla frutescens var. acuta)은 흔히 차조기, 자소엽 등으로 불리며, 식재료나 약재로 이용된다. 최근 들어 자소엽을 향장 원료로 활용하고자 하는 시도가 이루어지고 있다. 따라서 유기자재 처리를 통해 향장원료 자소엽의 고품질 생산을 위하여 본 시험을 실시하였다. 전북 농업기술원 허브산채시험장에서 육묘한 종묘를 2020년 5월 노지 포장에 주간 간격 50cm 한줄 재배로 정식하였다. 처리는 규산염(성분량 20%), 키토산(성분량 5%)가 함유된 자재를 각각 500배, 1,000배 희석하여 6월 21일, 8월 3일, 8월 23일 총 3회에 걸쳐 압축 분무기를 이용해 작물이 충분히 적셔지도록 살포하였으며, 무처리구는 물을 살포하였다. 초장, 초폭, SPAD, 생체중, 건물중을 조사하였으며 잎과 꽃의 총 폴리페놀 함량, 총 플라보노이드 함량, FRAP(철환원 항산화력) 활성 ABTS+ 라디칼 저해활성을 측정하였다. 생육특성 중 초장과 초폭은 처리간 유의성은 없었으나 무처리, 규산염 500배, 키토산 1,000배 처리에서 대체로 높았으며, SPAD는 키토산 1,000배가 가장 양호하였다. 수량성은 모든 자재 처리구가 무처리구보다 많았으며, 지상부 생체중은 무처리 대비 키토산 1,000배는 14.1%, 건물중은 무처리 대비 11.9%로 키토산 1,000배 처리가 수량성이 가장 많았다. 총 폴리페놀 함량은 꽃보다 잎에서 더 높은 수치로 나타났으며, 잎의 폴리페놀 함량은 규산염 500배 처리에서 가장 많았다. 꽃은 1,000배 처리에서 가장 높았다. 총 플라보노이드 함량은 꽃이 잎보다 높았으며, 잎은 규산염 500배 처리, 꽃은 키토산 1,000배 처리에서 함량이 가장 많았다. FRAP 활성은 잎의 경우 규산염 500배 처리에서 높았으며, 꽃의 FRAP 활성은 키토산 1,000배에서 좋았으나 처리 간의 차이는 크지 않았다. 자소엽 잎의 ABTS+ 라디칼 저해 활성은 규산염 500배 처리에서 가장 높았으며, 꽃은 경우 무처리에 비하여 자재 처리가 높았으며, 500배보다 1,000배 처리에서 높은 라디칼 저해 활성을 보였다. 이상의 결과, 자소엽 유기자재 처리는 무처리보다 대체로 수량성과 항산화 활성이 높았으나 추가적으로 적정농도 구명 후 경제성 분석이 필요할 것으로 판단된다.

In other words, interest in eye makeup started with 'self-care', showing interest in chasing a trend. Second, concerning the effects of appearance satisfaction on interest in eye makeup, as the respondents were more satisfied with their facial contour, they were more interested in eye makeup. Third, in terms of the influence of appearance satisfaction on eye makeup care behavior, as they were more satisfied with their skin conditions, trend-setting makeup care behavior increased. Consequently, increase in appearance satisfaction enhanced interest in eye makeup, having an influence on makeup care behavior.

The extracts of antioxidants, torreya nucifera and alphinia henryi, were tested for properties as a fragrance material and applied to a mask pack formulation to study the fragrance properties. The DPPH antioxidant test of hot water and ethanol extract confirmed that the ethanol extract had superior antioxidant efficacy compared to the hot water extract. It was confirmed that the optimal mixing ratio as a raw material for the mask pack of torreya nucifera and alphinia henryi was 3:7 as a result of the DPPH antioxidant test. As a result of the cytotoxicity test, the cell viability was good as it showed 103.30% at 0.5 ug/mL, 104.25% at 1 ug/mL, 102.56% at 5 ug/mL, and 99.17% at 10 ug/mL compared to the untreated group. As a result of the patch test on the mask pack formulation, the skin irritation index of 0.02 was judged as a non-irritation product in the skin irritation primary stimulation human application test. In the evaluation of skin moisturizing, it showed a significant increase rate of 19.178% compared to before the sample adaptation. Evaluation of the change over time in the sheet mask pack formulation confirmed the formulation stability without viscosity and pH change for 12 weeks at low temperature(4℃), room temperature(25℃), and high temperature(45℃).

This paper studied Joseon royal incense, Buyonghyang, focusing on the case of Sunjo Sunwonwanghoo Garyedogam Uigwe. Incense was introduced to Korea in the period of the Three States with Buddhist cultures. Buyonghyang is an incense that represented the royal family and was used in various rituals. Civilians also burned this incense in front of a bride's palanquin at a wedding ceremony. Buyonghyang had various uses-ceremonial uses, as a fragrance, to mothproof, and medical uses. Buyonghyang is a combined incense with ten different ingredients. This study tracked the supply and demand of the incense ingredients through Takjijunjeol, Sejong Shilok Jiriji, and The Annals of the Joseon Dynasty. This paper identified properties of the ingredients and studied recipes using ancient medical books-Jejungshinpyeon, Donguibogam, etc. Then the cooperation and treatment of incense by craftsman were examined using the records of The Annals of the Joseon Dynasty, and Seungjeongwon Ilgi. The significance of Buyonghyang during the Joseon dynasty was studied by examining its use at a royal wedding ceremony. This study considered Sunjo's wedding ceremony based on Sunjo Sunwonwanghoo Garyedogam Uigwe which is highly regarded as a well-organized system compared to other Uigwe. Buronghyang was burned during all of the ceremonies which took place in the palace. Conversely, it is considered that Buyonghyang was burned only during the Bisuchekui ceremony (investiture), which took place in the bride's place, according to the record of the mobilization of court ladies for various incense burners for the Bisuchekui ceremony. Since the incense was able to be used only after Bisuchekui, it is considered that only the royal family could use the incense, and it was a symbolic incense of the Joseon Royal Family.
