This study evaluated the biological properties of lemongrass (Cymbopogon citratus) extracts. The EtOAc extract of lemongrass had DPPH, TEAC, and nitric oxide-scavenging activity assay results of 58.06, 44.14, and 41.08% at the concentration of 50, 10, and 50 ㎍/ml, respectively. The EtOAc extract had higher elastase and collagenase inhibitory activities than the 80% MeOH, n-hexane, BuOH, and water extracts and comparable whitening activity toward monophenolase or diphenolase. Also, the EtOAc fraction had higher lipase inhibitory and antimicrobial activities against Cutibacterium acnes among extracts which is known to an important contributor to the progression of inflammatory acne vulgaris, and an opportunistic pathogen present in human skin. Total phenolic and flavonoid concentrations in the EtOAc extract were 132.31 mg CAE/g extract and 104.50 mg NE/g extract, respectively. Biologically active compounds in lemongrass extracts were analyzed by LC-MS. This study confirms that lemongrass extracts have potential use as cosmetic skincare ingredients. Thus, lemongrass can be considered a promising natural source of readily available, low-cost extracts rich in antioxidant, skincare, and antimicrobial compounds that might be suitable for replacing synthetic compounds in the cosmeceutical industry.

Traditional Asian medicine has an extensive evidence base built upon thousands of years of experience within Asia, of curing various diseases. Only recently, within the past two centuries, have modern medical scientists developed interest in traditional Asian medicine. Asian Medicine seems to be regarded only as an adjunctive medicine and viewed as alargely un-proven alternative medicine to complement western medicine, used in some cases to establish a new paradigm of "integrative medicine". This article reviews how Korean herbal cosmetics emerged by applying traditional Asian medicine to the science of cosmetics. The characteristics of Korean herbal cosmetics are examined through examples of history, concepts and traditions. With the advancements in biotechnology, studies are now being conducted on the dermatological effects and processing methods of herbal ingredients, including ginseng. The authors explain the current research on the identification on the active ingredients of herbs, extraction methods, and bio-processing of ingredients to improve the biological efficacies of herbs on the skin. A summary of studies focused on modern reinterpretations of ageing theories, such as 'Seven year aging cycle', are provided. In conclusion, the development of Korean cosmetics products are based on the accumulated knowledge of thousands of years of experience including; 1) practical heritage of traditional Asian medicines such as Donguibogam; 2) excellent medicinal plants, such as ginseng, which are native to Korea; and 3) innovative attempts to modernize materials, processes, and principles.

The demand for skincare has increased due to the end of the COVID-19 pandemic, leading to a focus on skincare devices and technologies designed to improve the delivery of cosmetics. Among these technologies, skincare medical devices that utilize plasma therapy (Plasma) and sonophoresis (Sono) are commonly used in dermatology clinics. However, there is still a lack of quantitative analysis for transdermal absorption effects of Plasma and Sono skincare medical devices. In this study, we quantified enhanced transdermal absorption effects of Plasma and Sono devices through in-silico and ex-vivo studies. The Sono treatment demonstrated an increased transdermal absorption effect, showing a 10~13% difference in penetration compared to the control group in the in-silico experiment, and 159% and 184% increase in the ex-vivo experiment. The Plasma treatment revealed increased transdermal absorption effects, with a 1.0~2.5% penetration difference in the in-silico experiment, and a 124% increase in the ex-vivo experiment compared to the control group. We also observed a synergistic effect from the combined treatment of Plasma and Sono, as indicated by the highest increases of 197% and 242% in penetration. Furthermore, we have determined the optimal device settings and treatment conditions for Plasma-Sono skincare medical devices. Notably, higher on/off durations (Intensity levels) and longer Sono treatments resulted in greater transdermal absorption effects.

에어졸 제품에 주로 사용되어왔던 프레온 가스는 오존층 파괴 등의 나쁜 영향으로 인해 액화석유가스(LPG)로 대체되었다. 따라서 본 연구에서는 프레온 가스가 아닌 액화석유가스를 이용하여 피부에 냉감 효과를 줄 수 있는 화장품을 개발하였다. 냉감 효과는 분사할 때 형성되는 얼음의 지속력에 의해 결정되었으며 얼음의 성상 관찰을 통해 최적의 원액 처방과 액화석유가스의 혼합비율을 선정하였다. 원액의 처방에서는 향을 가용화시킨 스킨타입으로 제조했으며 투명 내압용기를 이용하여 원액과 액화석유가스의 유화안정성을 평가하였다. 액화석유가스의 성분비(프로판:이소부탄:노말부탄)는 원액을 분사할 때 생성되는 얼음의 성상에 가장 큰 영향을 미쳤으며 프로판 가스의 함량이 높을 경우 분사압력이 높아 생성되는 얼음이 분사압력에 의해 부서지는 현상이 생겨 일정한 부피의 얼음을 얻기가 어렵게 된다. 실험결과 프로판 가스의 함량이 $3\%$미만이고 이소 부탄 가스의 함량이 $20\%$이상이며 노말 부탄 가스의 함량 $60\%$이상일 경우 최적의 얼음이 생성되었다. 또한 원액과 액화석유가스의 혼합 비율도 얼음 생성에 큰 영향을 미쳤으며 액화 석유가스의 양을 원액의 양을 기준으로 최소한 $50\%$ 이상 사용할 경우 얼음이 생성되었다.

As Korea's representative medical text, "Donguibogam" reveals Korean Medicine's unique perspective on the human body. The text also contains abundant resources related to skin, leading to diverse researches on the subject today. In this paper, authors tried to elicit values of "Donguibogam" in the general cosmetics field, through literature review. First, prescriptions related to main functions of modern cosmetics (anti-aging, whitening, and moisturizing) were classified. In relation to anti-aging, concepts such as 返老 (reversing aging), 還童 (to become young again), 皺 (wrinkle), and 皮急 (tense skin) were extracted and 69 examples of treatments were introduced. For whitening care, 41 treatments were mentioned on hyper-pigmentation and general complexion. Concepts related to moisturizing included expressions such as 潤肌膚 (hydration of skin) and 光澤 (glow), induced by 48 treatment prescriptions. Second, cosmetics related prescriptions were classified according to the application methods of modern cosmetics. 78 prescriptions of cleansing category included washing-off local area with herbal liquid, bathing, washing-off after steaming, and soaking the body in the herbal liquid. Total of 308 topical application prescriptions covered the conditions of various skin inflammations, scalp illnesses, and etc. In conclusion, this research examines the value of "Donguibogam" as a useful of skincare. Further studies are expected to extend our understanding of the field.

Purpose: This study aims to examine how to review contents of experiential and utilitarian products (e.g., skincare products) and how to affect review helpfulness by applying natural language processing techniques. Research design, data, and methodology: This study uses 69,633 online reviews generated for the products registered at Amazon.com by 13 Korean cosmetic firms. The authors identify key topics that emerge about consumers' use of skincare products such as skin type and skin trouble, by applying bigram analysis. The review content variables are included in the review helpfulness model, including other important determinants. Results: The estimation results support the positive effect of review extremity and content on the helpfulness. In particular, the reviewer's skin type information was recognized as highly useful when presented together as a basis for high-rated reviews. Moreover, the content related to skin issues positively affects review helpfulness. Conclusions: The positive relationship between extreme reviews and helpfulness of reviews challenges the findings from prior literature. This result implies that an in-depth study of the effect of product types on review helpfulness is needed. Furthermore, a positive effect of review content on helpfulness suggests that applying big data analytics can provide meaningful customer insights in the online retail industry.

The study aims to investigate the antecedents affecting purchase intention in the category of green skincare products. Many studies have used the theory of planned behavior to investigate factors affecting intention to purchase products in general. This paper not only retests the influences of attitude, subjective norm, perceived behavioral control on the intention to buy eco-friendly skincare products but also suggests a new antecedent - environment knowledge of purchase intention. More importantly, this study is the first to propose the moderating effect of country of origin and product knowledge on the relationship between attitude and purchase intention. This study employs a sample of 350 female customers from 18 to 39 years old in Ho Chi Minh City. The research applies the Multiple Linear Regression to analyze the proposed hypotheses in the conceptual framework and results in significant outcomes. The result shows that attitude is the most influential factor then, subjective norm, perceived behavioral control and environmental knowledge. Most importantly, the findings of this study suggest that product knowledge is found to moderate the effect of attitude on purchase intention. The finding of moderating effect is a new contribution to the literature and future research can be carried out to validate this result.
