전 세계는 covid 19의 pandemic 상황이 장기화되면서 화장품 분야의 trend 변화가 일어나고 있다. covid 19의 예방으로 마스크는 생활필수품이 되었고, 행정적으로도 사무공간에서도 마스크를 착용하지 않으면 과태료를 부과하는 상황에 이르렀다. 이로 인하여 장시간 마스크 착용은 필수 불가결한 상황이며, 이로 인하여 얼굴 피부의 장벽기능(barrier function)의 와해로 인하여 피부가 예민해지고 크고 작은 피부의 trouble이 많이 발생하고 있다. 이에 따라 소비자들은 화장품의 선택에 있어 피부 진정과 피부에 자극완화(anti-irritation) 및 안전성(safety)에 대한 것으로 점차적으로 변화하고 있다. Covid 19 이전의 화장품 소재 및 제품 개발의 트렌드는 국내의 기능성화장품 범주에 있는 미백 관련, 주름관련, 자외선 차단관련, 염모관련, 육모 탈모 관련, 여드름관련, 피부장벽관련, 튼살 관련 기능성 소재 및 제품 개발과 화장품 용도외의 고기능성 부여를 위한 코스메슈티컬(cosmeceutical)용 제품의 개발이 중요한 시기였다. 코스메슈티컬(cosmeceutical)은 화장품(cosmetic)과 의약품(pharmaceutical)의 합성어이다. 그러나 최근 Covid 19의 상황에 따라 화장품 업계는 포스트 코로나의 트렌드로 피부 장벽기능 강화, 피부노화 억제, 식물성, 자극완화, 비건, 안전성 확보에 대한 다양한 천연 소재의 연구와 제품을 개발 출시하고 있다. 따라서, 2020년 Covid 19의 상황에 따른 화장품 분야의 천연 신소재 및 화장품 개발 방향에 대하여 자원 식물의 활용성 및 개발 동향에 대하여 논의 하고자한다.

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.

There is growing interest in natural cosmetic ingredients as natural cosmetics become popular. As a part of effort to look for natureal cosmetic agent, seaweed Sargassums were tested for functional cosmetic agents. Effective materials were extracted from Sargassum coreanum. Sargassum hemiphyllum, and Sargassum patens by simple hot water extraction. Antioxidation, whitening, anti-wrinkle, UV absorption and anti-inflammation effects were studied for functional cosmetic agents. Sargassum extracts indicated excellent cell viability, strong anti-oxidation effect by DPPH radical scavenging activity and showed significant whitening effect from tyrosinase inhibition. However, effects of antiwrinkle, UV absorption and anti-inflammation were negligible. In conclusion, Sargassum coreanum extracts showed good possibility for anti-oxidation and whitening cosmetic agent.

In this research, root extracts of Nelumbo nucifera was tested to see the possibility for functional cosmetic agent. 70-100% ethanol was used as solvent and nuciferin was confirmed as active component. To test cosmetic effect of root extracts of Nelumbo nucifera, safety effect(MTT assay), anti-wrinkle effect(elastase inhibition assay) and antioxidation effect(DPPH free radical scavenging assay) were measured. When 100% ethanol was used as extracting solvent, cell viability was over 80% at $100{\mu}g/ml$, which indicated that root extract of Nelumbo nucifera was suitable for cosmetic agent. Root extract of Nelumbo nucifera showed 40~50% elastase inhibition at $100{\mu}g/ml$ so that it had good anti-wrinkle characteristics. 50% antioxidation capacity($FSC_{50}$) was $5.0{\sim}38{\mu}g/ml$ and root extract of Nelumbo nucifera showed excellent antioxidation effect. From the research, root extracts of Nelumbo nucifera showed strong possibility for anti-wrinkle functional cosmetic agent.

In this study, we tried to verify the value of the use of Mucuna pruriens (M. pruriens) extract as an antioxidant functional cosmetic material based on natural materials. After extracting, concentrating, and freeze-drying M. pruriens with water, 70% ethanol, and 70% acetone as solvents, samples of powdered hydrothermal extract (MW), 70% ethanol extract (ME), and 70% acetone extract (MA) were prepared. As a result of analyzing antioxidant activity through DPPH radical scavenging activity, ABTS⁺ radical scavenging activity, SOD-like activity, reduction ability, total phenol and flavonoid content analysis using MW, ME, and MA, all showed excellent antioxidant effects. Therefore, it is believed that M. pruriens extract is highly likely to be used as a natural material for antioxidant-related functional cosmetics.

Porcine placenta was treated with alkali, acid and enzyme treatment to obtain extracts. Heavy metal contents such as Pb, As, and Hg were low enough to satisfy cosmetic agent standard. As a result of safety test(MTT assay), porcine placenta extracts showed over 80% of cell viability at $50{\mu}g/ml$, and cell toxicity was relatively lower. From antioxidation test using DPPH free radical scavenging assay, antioxidation effect was highest as 63% at $50{\mu}g/ml$ when porcine placenta was treated with alkali in pH 9. From whitening effect test using tyrosinase inhibition assay, tyrosinase inhibition effect was 30% at $50{\mu}g/ml$ concentration in alkali treated procine placenta, however, the efficiency was lower compared with arbutin or vitamin C. In anti-wrinkle effect test from elastase inhibition assay, elastase inhibition effects were 20~30% at $50{\mu}g/ml$ for 5 kinds of porcine placenta treatments, which was superior to standard, and especially, protease treated extracts showed best results. Skin formulation including 1% porcine placenta was made and the formulation was very stable for temperature and storage period. From this research, porcine placenta extract showed high potential for anti-wrinkle functional cosmetic agent.
