Purpose: Here, we evaluated the safety and effectiveness of Jeonnam's unique resources, such as Dendropanax, sea salt, spinach, and kelp, to develop functional cosmetics that may alleviate hair loss. Methods: We performed safety tests with these resources, testing for heavy metals and cytotoxicity, and we evaluated their effectiveness as anti-microbial, cell proliferation, and anti-inflammation products. Results: The heavy metals concentration was lower than or in trace levels, as recommended by the Ministry of Food and Drug Safety's standard of extracts such as Dendropanax, sea salt, etc. We confirmed cytotoxicity to be safe. In each extract, the concentrations of Dendropanax, sea salt, spinach, and kelp were 0.01 mg/mL, 5 mg/mL, 0.5 mg/mL, 0.5 mg/mL, respectively. Only the Dendropanax extract had microbial effect, with the distilled water extract reaching the highest effect. The cell proliferation increased to 0.5 mg/mL, 5 mg/mL, and 2 mg/mL for Dendropanax, spinach, and kelp with distilled water extract, the anti-inflammation effect increased. Conclusion: We found that Dendropanax, sea salt, spinach, and kelp were safe and effective as functional cosmetic materials to alleviate hair loss symptoms through optimal standardization. We suggest further research to evaluate these cosmetics' functional effects.

et al. 2021

Purpose: This study investigated how choice attributes and safety perception of adult female consumers influence purchase intention.Methods: Data were collected from women aged 20 years and older and analyzed using SPSS WIN 25.0 program. Analyses included frequency, descriptive statistics, cross-tabulation, one-way ANOVA, factor, reliability, principal component, and regression.Results: Among the attributes of personalized cosmetic selection, quality was highly significant for women aged 40 and older. As regards the safety perception of customized cosmetics, the safety of the manufacturing environment was significantly important for women in their 30s and that of the expiration date, and the ingredients were significantly higher for women aged 40 and above. The significance of safety was high in the case of married women and those in the income group above 4 million won. Quality has the greatest positive impact on safety of the manufacturing environment and shelf life, and perceptual value has the greatest positive impact on universal safety. Perceptual value and universal safety had the greatest positive influence on purchasing intention.Conclusion: Through this study, we increase the safety perception of customized cosmetics to consumers who choose customized cosmetics and help them select customized cosmetics according to their selection attributes. For related companies, we not only hope to develop customized cosmetics with proven safety but also build and develop appropriate marketing strategies.

Purpose: This study aimed to explore the differences in the antioxidant activity and anti-inflammatory effects of Gloiopeltis furcata based on its extraction conditions.Methods: 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays were performed to determine the antioxidant activity of Gloiopeltis furcata extracts obtained using different concentrations of ethanol. Concomitantly, the concentrations of polyphenols and flavonoids, which are antioxidants present in Gloiopeltis furcata extract, were measured. Additionally, in cell-based experiments, the cytotoxicity and anti-inflammatory activity of a water extract, which exhibited the most potent antioxidative activity among all extracts, was measured.Results: In the DPPH assay, the Gloiopeltis furcata extract exhibited an antioxidant activity of 3.576 mg of ascorbic acid/g, whereas in the ABTS assay, the antioxidant activity was 4.892 mg of ascorbic acid/g. The polyphenol concentration was found to be 35.52±2.32 mg/g, whereas the flavonoid concentration was 0.88±0.34 mg/g. Furthermore, the extract had a cytotoxicity of ≤20% at all concentrations used in the experiment, thus indicating the absence of cytotoxicity and confirming that the extract was effective in reducing inflammation proportionally to its concentration. Moreover, the extract exhibited an anti-inflammatory activity of 47.66%±1.53% at a concentration of 100 μg/mL.Conclusion: Gloiopeltis furcata exhibited the most potent antioxidant activity in its water extract, and it was confirmed that the extract of Gloiopeltis furcata that was obtained through water had low cytotoxicity, an anti-inflammatory effect, and a commercial value.
