This study introduces the case of a company that newly jumped into the competitive cosmetics market with a brand concept developed through big data analysis. Skin Reverse Lab, which possesses anti-aging material technology, launched a new brand in the skincare cosmetics market. Using a big data analysis program called Luminoso, SNS data was analyzed in four areas, which were consumer attitudes toward overall cosmetics, skincare products, competitors, and consumers' experiences of product use. The age groups and competitors were analyzed through the emotional analysis technique including context, which is the strength of Luminoso, and insights on consumers were derived through the related word analysis and word cloud techniques. Based on the analysis results, Logically Skin have won various awards in famous magazines and apps, and have been recognized as products that meet global trend standards. Besides, it has entered six countries including the United States and Hong Kong. The Logically Skin case is a case in which a new company entered the market with a new brand by deriving consumer insights only from external data, and it is significant as a case of applying AI-based sentiment analysis.

Consumers focus on information about the symbolic meaning of a product for highly involved and emotional products (such as cosmetic products). This study examines the effectiveness of the congruence between cosmetics advertising image and self-image on consumer attitudes. In addition, this study examines two additional moderating effects, which are 'product type' and 'message type'. For the experiment, four advertizing type factorial designs were performed. A total of 320 undergraduate female students in Korea participated in the experiment. This study captured the subjective judgments of consumers on these three comparisons in terms of advertizing attitude, brand attitude, and purchase intention. The results are as follows: First, the greater the self-congruity on cosmetic advertising, then the greater the effectiveness on advertizing attitude. Second, the increased self-congruity on cosmetic advertising did not create greater effectiveness on brand attitude. Third, increased advertizing attitudes on the congruence between cosmetics advertising image and self-image increased the effectiveness on brand attitude. Fourth, increased advertizing attitudes on the congruence between cosmetics advertising image and self-image improved the effectiveness on purchase intention. Fifth, the greater the brand attitude (on the congruence between the cosmetics advertising image and the self-image produced)increased the effectiveness for purchase intention. The results show a significant moderating role of the product type. Marketers can use the results of this study to understand the market of cosmetic products for promotion.

The purpose of this study was to verify the efficacy of cosmetics containing peptides as a cosmetic method for eyelashes. The study subjects were 21 women aged 20 years, set as the experimental group (right eyelash) and the control group (left eyelash), and measured changes according to the use of peptide cosmetics for 4 weeks. As a result of the analysis, the change in the length and density of eyelashes showed significant differences in the interaction between the group and the experiment period, and in the main effect according to each experiment period (p<.001). In the change of eyelash density and thickness, it was found that there was a significant difference at week 3 and week 4 in the difference between groups by measurement period (p>.05, p>.01). Cosmetics containing peptides have been effectively proven to be an effective cosmetic method for safe and beautiful eyelashes by increasing the length and number of eyelashes to those who suffer from side effects caused by cosmetic procedures. In the future, we look forward to expanding research to a wide range of age groups.

In our increasingly aged society, the term centenarian, meaning people 100 years old or older, is used more and more frequently. Indeed, anticipating long life, middle-aged to advanced-age people have changed their lifestyles to purchase goods for themselves. In addition, as the social trend of careful grooming for positive appearance spreads within the Korean society, the demand for senior male cosmetic products is likely to grow as the society ages further. However, previous large studies on the market for senior male cosmetics are limited. Since information is lacking about senior male consumers' awareness of cosmetics, this study examined their use of cosmetic products, purchase behaviors, and demand for cosmetics in order to explore correlations among interest levels in appearance, cosmetic purchase behavior, and cosmetic demand levels through diverse factors related to multiple variables. The results of this study were as follows : First, the more senior men managed their practical appearance, the more frequent their functional and psychological purchase behaviors. Second, the higher their practical purchase behavior, the stronger their demand for reasonable cosmetic prices. Third, the higher their value-oriented purchase behavior, the stronger the demand for greater product diversity. This study investigated men aged 50 or older residing in Seoul. Therefore, generalizing the findings of this study will be limited. Relevant subsequent studies should examine men aged 50 or older in each Korean region and more clearly identify the correlations among interest in appearance, cosmetic product purchase behavior, and cosmetic product demand using various factors related to multiple variables.

Formulations which are dispersed in water are often used in color cosmetics because they are characterized by no powder flying, not sticky, and high adherence while giving a light feeling of use. However, little research has been considered on the effect of the pigment on the above formulations used in color cosmetics. In this study, experiments were conducted to measure and analyze the effect of pigments on the formulation of pigments, organic pigments, and pearl polish, which are mainly used in the manufacture of color cosmetics, on appearance changes, pH changes, and photometric stability. Carmine or ferric ferrocyanide coated titanium dioxide mica-based pigments were not suitable for use due to poor photostability, with colors appearing on the surface from low viscosity formulations. Organic pigments had a good photostability of 1% of the formulation which are dispersed in water, but were not suitable for use because they came out of color on the water surface and did not spread well due to the clumping of powders. The titanium dioxide mica system pigments coated with pearl polish, inorganic pigments, and iron oxide were suitable for use due to their excellent appearance and optical stability in the formulation. Furthermore, the pH of all samples distributed by each pigment seems to be within the range of 3.0 to 9.0, which is suitable for cosmetic applications. This is expected to help manufacture color cosmetics with a stable water dispersible formulations by selecting and using stable pigments in anticipation of the behavior of pigments in the formulations.

This study investigated the effect of the price and brand name on the consumer's evaluation of cosmetics. 363 women from 20's to 50's living in Seoul and the metropolitan area were asked to use and describe the given samples of cosmetic products for one week with different information of price and brand name. The results of this study are as follows: First, the assessment of the facial toner, moisturizer and cream does not show a significant statistical difference between the group of 'renowned' and 'renownless'. Second, the assessment of the facial toner, moisturizer, and cream shows a significant statistical difference between the user groups which received the prior information whether the cosmetics are 'high price' or 'low price'. Third, the assessment of the users' satisfaction of the 3 kinds of cosmetic products mentioned above is influenced by 'renown' an 'price'. Finally, the interaction of the factor 'renown' and 'price' influences on the cosmetics' effectiveness significantly. From this study, it was discovered that the evaluation and the degree of satisfaction on cosmetics were influenced by the price and brand names. This will improve the understanding of consumers' behavior and personal decision-making, which in be the key of marketing strategy.

This study is focused on the effect of sodium stearate, which is a hydrophilic gelling agent affecting on the hardness of O/W solid sunscreen cosmetic. The sunscreen of the O/W (oil in water) type is stable, good in use, and relatively easier to stabilize than the sunscreen of the W/O (water in oil) type. Methods for increasing the stability by using emulsifiers, electrolytes, and wax or oil have been studied for solid sunscreen. This study was intended to develop a solid sunscreen stabilized by increasing the hardness using sodium stearate as an O/W type containing more than 40% moisture. Response surface methodology (RSM) was used to analyze the factors affecting the hardness of cosmetics, and sodium stearate, polyol and oil were used for each factor. The hardness and the reaction value was measured using a rheometer. As a result, sodium stearate showed a meaningful value (p < 0.05) among the three factors affecting hardness. In addition, the use of sodium stearate as a hydrophilic gelling agent increased the usability and stability of the solid sunscreen.

Natural halloysite is mostly found in the form of a tubular structure with a 15-125 nm internal lumen. This kaolin clay can be used for encapsulating a liquid ingredient of cosmetics and for immobilizing an inorganic solid-phase ingredient. In this paper, the encapsulation and immobilization procedures are introduced and two example applications are reviewed to demonstrate the usefulness of halloysite as a cosmetics substrate. It may help attract more interest in cosmetic applications of halloysite and thus spur more research on the utilization of natural clays.

Most of cosmetics are emulsion products that contain the source of nutrition vegetable oil, mineral oil, natural extract and carbohydrate etc. There are many possibilities to be contaminated by microbials. We investigated the effect of antimicrobial and minimum inhibitory concentration(MIC) with thiamine dilauryl sulfate(TDS), which was prepared to use cosmetic lotion formulation. Staphylococcus aureus(S. aureus) and Escherichia col(E. coli) were used as test organism. MIC value of TDS was determined aganist microorganism for the growth inhibition by concentration of TDS. From the MIC results, antimicrobial effect of TDS was generally more effective to gram positive than gram negative. Antimicrobial effect with pH value against some microorganism appeared in the following order : pH 5 > pH 6 > pH 7. It showed strong antimicrobial activities against S. aureus, and weak antimicrobial activities against E. coli. If it was possible to determine the formulations with TDS, it would be effective to reduce the artificial preservatives.
