The effects of Lavandula angustifolia extract fermented with Pediococcus pentosaceus DK1 on UVB-mediated MMP-1 expression and collagen decrease in human skin fibroblasts were determined, and the conversion of its components was also analyzed. Fermentation was performed at varying L. angustifolia extract and MRS medium concentrations, and optimal fermentation conditions were selected. L. angustifolia extracts showed decreased cytotoxicity after fermentation in the fibroblasts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extract showed MMP-1 expression 8.2-14.0% lower than that in UVB-irradiated fibroblasts treated with non-fermented extract. This was observed even at fermented extract concentrations lower than those of non-fermented extracts. Fibroblasts treated with fermented L. angustifolia extract showed 20% less reduction in collagen production upon UVB irradiation than those treated with non-fermented extracts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extracts showed 50% higher inhibition of ROS generation than those treated with non-fermented extract. Luteolin and apigenin glycosides of L. angustifolia were converted during fermentation, and identified using RP-HPLC and LC/ESI-MS. Therefore, the effects of L. angustifolia extract on MMP-1 expression and collagen decrease in UVB-irradiated human skin fibroblasts were increased through fermentation by P. pentosaceus.

In this study, we developed cosmetic container's volume index to compare the packaging volumes of fundamental cosmetic types. Over 250 cosmetics used for this study were collected in Korean market. The written content volume and the outer volume of packaging were analyzed to establish volume index (Lcos) and a design guideline for cosmetic container. The allowable ranges, such as maximum, acceptable, and optimum ranges in the design process, were also determined using Lcos. About 37% of cosmetics were in optimum or acceptable ranges. A 15% of cosmetic packages was in maximum range for reducing their volumes. This cosmetic container's volume index may be a useful tool as a design guideline for cosmetic packaging development.

Korean cosmetic distribution channels were formerly divided into sales visits and specialty shops, which made up the entire cosmetics market. However, recently the market and cosmetic distribution channels have become much more diversified. Thus, research for this study focused on the usage and purchase situations of cosmetic distribution channels depending on cosmetic type perception. This study also focused on the intent to purchase cosmetics by a cosmetic distribution channel in order to provide a precise cognitive background of consumers regarding cosmetic distribution channels. In doing so, the competitiveness of those channels could be procured and the causal relationships between these variables can be investigated. To achieve these purposes, the research model and hypotheses were derived through literature research on the cosmetics industry, cosmetic distribution channels, and consumers' intent to purchase. A survey was implemented from September $1^{st}$ to $14^{th}$, 2014 for empirical testing. and was given to female consumers in their 20s. 468 out of 500 surveys were collected; a total of 415 were used for analysis while the others were excluded due to with unreliable responses. The SPSS 21.0 program was used for analysis of materials. The overall conclusion of this study is that there is a relationship between perception of cosmetic distribution channels and intent to purchase. The above research results may stimulate establishment of marketing implications and research material when establishing marketing strategies to promote cosmetic distribution and consumption.

The stem extract from Pyrus serotina var has natural antioxidant ability, but the extraction method does not result in a soluble compound in cosmetic formulations. This study investigated the cosmetic efficacy of the Pyrus serotina var stem extract and its epidermis permeation ability when combined with polymer micelles and a cell penetrating peptide. The total concentration of polyphenol compounds was determined to be 103.1644 ± 1.38 mg/g in the ethanol extract and 78.97 ± 1.45 mg/g in the hydrothermal extract. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effects were 55.94 ± 0.22% in the ethanol extract at 1,000 mg/L. Superoxide dismutase (SOD) activity rates were 104.05 ± 3.28% in the ethanol extract at 62.5 mg/L. The elastase inhibition rate was 67.21 ± 2.72% in the ethanol extract at 1,000 mg/L. An antimicrobial effect was observed in the Propionibacterium acnes strain. In the epidermal permeability experiment, it was confirmed that formulation of the polymer micelle containing the Pyrus serotina var stem extract and cell penetrating peptide (R6, hexa-D-arginine) showed small particle size and much better skin permeability. The cumulative amount of total Pyrus serotina var stem extract that penetrated to the skin over time increased over 24 hours in three formulations. The three formulations showed 51.61 ㎍/㎠ (Formulation 0), 75.97 ㎍/㎠ (Formulation 1) and 95.23 ㎍/㎠ (Formulation 2) skin penetration, respectively. Therefore, it was confirmed that the ethanol extracts of Pyrus serotina var stem showed good cosmetic efficacy and excellent epidermis permeation ability when combined with a polymer micelle and cell penetrating peptide. Thus, this extract has the potential to be used as a safe and natural cosmetic material in the future.

Background: The Rosa multiflora, a well-known plant belonging to Rosacea, is widely used in orthodox medicine in worldwide. However, its biological activity and cosmetic preservative efficacy have not yet been studied. Thus, this species is yet to be defined as a functional cosmetic material. Accordingly, an investigation of the above mentioned atrributes was performed on a 50% ethanol extract of Rosa multiflora. Methods and Results: The antioxidant activity was assessed through free radical scavenging assays with 2,2-diphenyl-1-picrylhydrazyl (DPPH). Additionally, the contents of total phenols and flavonoids were analyzed. The phenolic compounds were detected using HPLC. The antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans was assessed using the disc diffusion assay. The preservative effect (challenge test) on a formulation of soothing gel was performed for 28days. The DPPH radical scavenging ability, denoted by the $SC_{50}$ (half maximal inhibitory concentration for DPPH radical scavenging) value was found to be $131.63{\mu}g/m{\ell}$. The content of total polyphenol and flavonoid content were 202 mg/g and 86.77 mg/g, respectively. In additon, astragalin and gallic acid were identified in the extract. The antimicrobial activity of the extract against S. aureus and E. coli was observed to be 5 - 0.5%, and no significant activity was noted against C. albicans. The ethanol extracts (5% and 10%) met the preservation standards of the Cosmetics, Toiletry, and Fragrance Association (CTFA). Conclusions: Thus the ethanol extract of R. multiflora can be used in cosmetics as a natural preservative and antioxidant.

Purpose: This study introduces a systematic framework to evaluate service satisfaction of cosmetic brands through online review analysis utilizing Text-Mining technique. Methods: The framework assumes that the service satisfaction is evaluated by positive comments from online reviews. That is, the service satisfaction of a cosmetic brand is evaluated higher as more positive opinions are commented in the online reviews. This study focuses on two approaches. First, it collects online review comments from the top 50 global cosmetic brands and evaluates customer service satisfaction for each cosmetic brands by applying Sentimental Analysis and Latent Dirichlet Allocation. Second, it analyzes the determinants that induce or influence service satisfaction and suggests the guidelines for cosmetic brands with low satisfaction to improve their service satisfaction. Results: For the satisfaction evaluation, online review data were extracted from the top 50 global cosmetic brands in the world based on 2018 sales announced by Brand Finance in the UK. As a result of the satisfaction analysis, it was found that overall there were more positive opinions than negative opinions and the averages for polarity, subjectivity, positive ratio, and negative ratio were calculated as 0.50, 0.76, 0.57, and 0.19, respectively. Polarity, subjectivity and positive ratio showed the opposite pattern to negative ratio, and although there was a slight difference in fluctuation range and ranking between them, the patterns are almost same. Conclusion: The usefulness of the proposed framework was verified through case study. Although some studies have suggested a method to analyze online reviews, they didn't deal with the satisfaction evaluation among competitors and cause analysis. This study is different from previous studies in that it evaluates service satisfaction from a relative point of view among cosmetic brands and analyze determinants.
