The first part of the paper concerneded about the history, meaning and function of the aromatherapy. And the next part is about the therapeutic effects by the inhalation fragrance or permeation of essential oil through the skin, which are all based on the recent experiments. Today, the aromatherapy is public interest in the world. And also many cosmetic companies have been making use of the aromatherapy as the concept of their new products. But any Korean manufacturer has not taken the application of the aromatherapy in the cosmetics. Why we can't do this. Therfore I try to explain this problem at the last part of the paper and also introduce some Aromatherapy products.

This study was conducted to investigate the antimicrobial activities of ethanol extracts (70%, v/v) from Whole, Root and Leaf stem part of dried Zostera marina. In order to use Zostera marina extract as a basic material of cosmetic component. The extracts of Zostera marina conducted an antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Propionibacterium acnes by disc diffusion method and measure clear zone. As a result, clear zone(mm) of Staphylococcus epidermidis was confirmed at $13.00{\pm}0.50mm$ and Staphylococcus aureus, Propionibacterium acnes, Pseudomonas aeruginosa have measured $11.75{\pm}0.25mm$, $12.00{\pm}0.50mm$, $12.25{\pm}0.25mm$ from Root extract part of Zostera marina. A Zostera marina extract is expectied to have antimicrobial effects.

This study evaluated the attitudes of the Korean population towards sunscreen use through the Health Belief Model (HBM) construct and investigated the psychological factors that influence sunscreen use. For this purpose, an online survey was conducted from 1 November 2023 to 1 January 2024, and a total of 303 participants were collected. The collected data were analysed using SPSS v. 25.0 programme using Cronbach's 𝛼, frequency analysis, descriptive statistics, correlation analysis, independent samples t-test, one way ANOVA, Scheffe's test, and multiple regression analysis. The results of the study showed that the mean score of sunscreen use was 3.26±1.384 out of 5, and there was a significant correlation between the variables of the health belief model and sunscreen use (p<.01). Gender, age, and skin colour were also associated with each variable, with women, the elderly, and those with lighter skin tending to be more proactive in sun protection. Multiple regression analyses revealed that self-efficacy (𝛽=.629, p<.001) and perceived vulnerability (𝛽=.139, p<.001), sub-factors of the Health Belief Model, had a statistically significant positive effect on sunscreen use, while perceived barriers (𝛽=-.261, p<.001) had a statistically significant negative effect on sunscreen use. These results may have important theoretical implications for the development and implementation of educational programmes to promote sunscreen use by providing insight into the psychosocial factors that influence sun protection.

Hyaluronic acid(HA) is a naturally occurring mucopolysaccharide composed of the repeating disaccharide unit of D-glucuronic acid and N-acetyl-D-glucosamine. HA exists as a high molecular weight polymer in the extracellular matrix of many tissues in the body. HA has been widely used not only for osteoarthritis and ophthalmology but also for cosmetics for skin care. Recently HA has drawin much attention for use in health foods. Bioland Corporation started production of HA t1y biotechnological process in 1990 for cosmetical use. At present Bioland produces HA for cosmetic and food use. We have done many researches to evaluate the helpful effect for skin and safety of HA as food. In order to evaluate the effect of HA on the skin after its oral intake, we measured its bioavailability, skin-care effects on anti-wrinkle, moisturization elasticity and desquamation by clinical trial. The results showed that HA is very safe and could bs helpful to improve anti-wrinkling, moisturization, elasticity, and desquamation on the skin.

This paper established a new smart factory based on manufacturing data for an introductory company focusing on the personalized cosmetics manufacturing industry. We build on an example of a system that collects, manages, and analyzes documents and data that were previously managed by CGMP-based analog for data-driven use. To this end, we have established a system that can collect all data in real time at the production site by introducing artificial intelligence smart factory platform LINK5 MOS and POP system, collecting PLC data, and introducing monitoring system and pin board. It also aims to create a new business cluster space based on this project.

For the use of tannins in the whitening-effect cosmetics, inhibitory effect against tyrosinase activity was determined. Three condensed tannins including gallocatechin, gallocatechin 3',4'-di-O-gallate and epicatechin 3-O-gallate and three hydrolyzable tannins, 1,2,6-tri-O-galloyl-${\beta}$-D-glucose, 2,3-(S)-HHDP-D-glucose and pedunculagin showed 15-29% mild inhibitory effects against tyrosinase activity.

Polyethylene glycols (PEGs) are products of condensed ethylene oxide and water that can have various derivatives and functions. Since many PEG types are hydrophilic, they are favorably used as penetration enhancers, especially in topical dermatological preparations. PEGs, together with their typically nonionic derivatives, are broadly utilized in cosmetic products as surfactants, emulsifiers, cleansing agents, humectants, and skin conditioners. The compounds studied in this review include PEG/PPG-17/6 copolymer, PEG-20 glyceryl triisostearate, PEG-40 hydrogenated castor oil, and PEG-60 hydrogenated castor oil. Overall, much of the data available in this review are on PEGylated oils (PEG-40 and PEG-60 hydrogenated castor oils), which were recommended as safe for use in cosmetics up to 100% concentration. Currently, PEG-20 glyceryl triisostearate and PEGylated oils are considered safe for cosmetic use according to the results of relevant studies. Additionally, PEG/PPG-17/6 copolymer should be further studied to ensure its safety as a cosmetic ingredient.

Chitin and chitosan has been almost neglected until 1960s, although they are the second largest biomass on earth. Their major use were as a natural flocculant for waste-water treatment, and partially used in the areas of food, feed industry, cosmetics and medicine. Possible sources of chitin among biomass were tested, and antibacterial activity and viscosity-concentration relation- ship of diluted acidic solution were examined.

This study investigated how consumers perceive brand image, the consistency between the images of parent brands and extended brands, the consistency of their advertising images, the differences between brand image and advertising image, and how consumers' brand attitudes change based on those differences. An online survey was administered to women in their 20s and 30s who often use cosmetics and are interested in brands. The brands considered in this research were Chanel, Dior, Armani, and Anna Sui, which have extended brands in the clothing and cosmetics areas. In terms of consumers' perception of brand image, it was found that clothing and cosmetic brands were perceived similarly. In addition, significant differences were found in consumers' preferences and purchase intentions of clothing and cosmetic brands, and those whose perceptions of brand image did not change or increased after looking at advertising images had more positive brand attitudes than the group of people who had higher perception of brand image before looking at advertising images. Therefore, in terms of brand extension, it was revealed that the image of a parent brand affected an extended brand, and that the higher was consumers' recognition of brand image through advertising, the more positive was their attitude toward the brand.

In this study, hot water and ethanol, acetone, and hexane extracts of the steamed Deodeok were investigated for use as raw materials for natural cosmetics. Hot water and ethanol, acetone and hexane extracts of steamed Deodeok did not indicate cell toxicity up to 300 ㎍/mL concentration in the MTT assay. The tyrosinase inhibition effects of the ethanol extract were higher than the ascorbic acid. The efficacy of the steamed Deodeok's ethanol extract on the elastase inhibition was similar to that of quercetin at higher concentrations. In conclusion, water, ethanol, acetone and hexane extracts of the steamed Deodeok indicated strong possibility as a whitening and anti-wrinkle functional cosmetic ingredient. Among them, the steamed Deodeok's ethanol extract, which showed excellent activity, is highly available because it has high safety compared to other organic solvent extraction methods used in cosmetics, and has minimal irritation to the skin.
