Various characteristics of Opuntia humifusa (O. humifusa) extract solution obtained under low temperature and reduced pressure were examined and cosmetic essences using the extract solution as a humectant were prepared. The O. humifusa extract solution represented very small surface tension (25 mN/m) and contact angle ($8^{\circ}$), compared with other humectants such as glycerine and 1% hyaluronic acid solution. Also, the viscosity and stickiness of the extract solution were very low. The O. humifusa extract solution made it possible for a small amount of oil to be dispersed stably in water without any surfactant. Unlike other humectants, the viscosity and stickiness of cosmetic essences were reduced as the extract solution content in formulation increased. These results show that the O. humifusa extract solution obtained under low temperature and reduced pressure can be used as a natural humectant that provides moisturizing property and less sticky feeling.

We evaluated the antioxidant activity and anti-wrinkle effects of Aceriphyllum rossii leaf ethanol extract (ARLEE) in vitro using human dermal fibroblasts. The total polyphenol and flavonoid contents of ARLEE were 578.6 and 206.3 mg/g, respectively. At a concentration of $250{\mu}g/mL$, the electron-donating ability of ARLEE was 87.1%. In comparison with the vehicle, ARLEE treatment at $100{\mu}g/mL$ significantly increased type I procollagen synthesis (p < 0.01) by 50.7%. In vitro ARLEE treatment (10 mg/mL) inhibited collagenase and elastase activity by 97.1% and 99.2%, respectively. Compared with the control, ascorbic acid treatment at $100{\mu}g/mL$ significantly decreased matrix metalloproteinase (MMP)-1 protein expression (p < 0.01) by 37.0%. ARLEE treatment at $50{\mu}g/mL$ significantly decreased MMP-1 protein expression (p < 0.01) by 46.1%. Ascorbic acid and ARLEE treatments at $100{\mu}g/mL$ significantly decreased MMP-1 mRNA expression (p < 0.01) by 26.1% and 36.1%, respectively. From these results, we conclude that ARLEE has excellent antioxidant activity and even better anti-wrinkle effects than ascorbic acid in human dermal fibroblasts. These results suggest that ARLEE could be used in functional cosmetics for the prevention or alleviation of skin wrinkles induced by ultraviolet rays.

In vitro tests were performed using CST to investigate its role on oxidative damages and inflammatory cytokines. 90% or higher cell viability was observed in CST treated groups from 25 to 200 ${\mu}g/m{\ell}$ using Raw 264.7 cells. CST showed dose-dependent DPPH scavenging activity, with 91.3% and 92.2% scavenging activities at 400 and 800 ${\mu}g/m{\ell}$ concentrations, respectively. CST showed dose-dependent suppression activity of ROS production, especially at 200 ${\mu}g/m{\ell}$ of 41.3%. CST decreased NO production activity, with significant decrease of 16.2% and 33.5% at 100 and 200 ${\mu}g/m{\ell}$ concentrations, respectively. IL-$1{\beta}$, IL-6, MCP-1 production rate were significantly decreased by 30.0%, 27.2%, 22.1% when Raw 264.7 cells were treated with LPS and with CST of 200 ${\mu}g/m{\ell}$. Also, TNF-${\alpha}$ production rate was decreased by 28.6%. The results above indicated therapeutic effect of CST on the AD through anti-oxidative and immune modulatory effect. Various blending of drug substances with CST should be clinically tested.

330 Korean adult women were examined the correlation between degree of makeup and makeup satisfaction before/after wearing masks due to COVID-19 and the moderating effect of mandatory/voluntary goal-oriented attitude toward makeup. The study found that lip makeup(p<.001) was significant variable in makeup satisfaction before COVID-19, and eyebrow makeup(0<.002) was significant after COVID-19. Although moderating effect of mandatory goal-oriented attitude, which works between degree of makeup before/after COVID-19 and makeup satisfaction was not significant, but moderating effect of voluntary goal-oriented attitude appeared to be significant before(p<.000) and after(p<.000) COVID-19. And the degree of makeup after COVID-19 was lower than before(p<.000). If one believe that makeup is for one's own satisfaction, degree of makeup can be significant effect on the makeup satisfaction, but actual behavior has shown that degree of makeup has decreased since wearing masks because of COVID-19. I hope this research will be used as marketing material for beauty and cosmetics industry.

Objectives : The experiment was performed to investigate promotive effects of haeae-tang (HET) extract, a traditional Korean medicinal recipe, on hair growth, protein and gene expression in hair-removed C57BL/6. Methods : In experiment, animals were divided into 3 groups including normal (vehicle), HET ethanol extract and 5% minoxidil-treated groups (Minoxidil, positive control). The vehicle or testing samples were daily treated with 0.2ml per on hair-shaved dorsal skin of C57BL/6mice for 15 days. Effects of testing samples on hair growth was monitored through phototrichogram analysis by folliscope on the initial, $5^{th}$, $10^{th}$, $15^{th}$ day, respectively. Also, gene and protein expressions of vascular endothelial growth factor (VEGF) and Insulin like growth factor-1 (IGF-1), relevant to hair growth, were examined. Results : Hair density and hair thickness of Minoxidil treated-group was significantly increased compared to that of vehicle application on the $15^{th}$day, respectively. Dorsal hair density of HET treated-group was significantly increased compared to that of vehicle application on the $15^{th}$day. In addition, the Minoxidil group significantly increased the expression of cutaneous IGF-1 protein and mRNA compared to that of the vehicle-applied group on the $15^{th}$ day. And HET-treated group significantly increased the expression of dorsal VEGF protein compared to that of the vehicle-applied group on the $15^{th}$ day. Conclusions : These results suggest that this Korean medicinal recipe, HET has promoting activity on hair growth in an Alopecia animal model thus it can be used as a material of agent or products for improvement or prevention of alopecia.

This study was conducted to measure the antimicrobial activity and antiseptic effect of Smilax china root extracts against Propionibacterium acnes and to develop natural antimicrobial extracts as an alternative for synthetic preservatives, which have recently been controversial. Extracts were obtained from dried Korean Smilax china root at room temperature using two solvents, distilled water and 95% EeOH, separately. According to the results of this study, the antimicrobial effect of Propionibacterium acnes 3314 and Propionibacterium acnes 3320 against Propionibacterium acnes was outstanding. In particular, the clear zone of the extract using distilled water showed the highest activity with 16.61 mm. As for the result of the collection of contaminated skin sample, the clear zone was 24.48 mm. This indicates that Smilax china root extracts show a high activity against skin flora as well as a high antimicrobial activity against Propionibacterium acnes. In conclusion, it is confirmed that Smilax china root extracts can be used as raw materials for cosmetics that have antimicrobial activity and antiseptic effect, and it is expected that Smilax china root extracts will be used as basic materials for the development of future natural preservatives.
