In this study, the antioxidant effect and component analysis for extract and fractions of Cardiospermum halicacabum leaf were investigated. All experiments were performed with 50% ethanol extract, ethyl acetate fraction and aglycone fraction obtained from dried C. halicacabum leaf. The yields of extract and fractions were 16.4, 0.9 and 0.3% per dried powder, respectively. DPPH (1,1-phenyl-2-picrylhydrazyl) radical scavenging activity ($FSC_{50}$) of ethyl acetate fraction ($92.5{\mu}g/mL$) was the greatest radical scavenging activity, but lower than (+)-${\alpha}$-tocopherol ($8.9{\mu}g/mL$). In reactive oxygen species (ROS) scavenging activity (total antioxidant capacity, $OSC_{50}$) on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system, aglycone fraction ($4.2{\mu}g/mL$) was the highest total antioxidant capacity and similar to L-ascorbic acid ($1.5{\mu}g/mL$). The cellular protective effects of C. halicacabum leaf extract and fractions on the $^1O_2$-induced cellular damage of human erythrocytes were exhibited at all concentration-dependent ($5.0-25.0{\mu}g/mL$). Especially, aglycone fraction (${\tau}_{50}$, 76.4 min) in $25.0{\mu}g/mL$ showed the most protective effect among extracts. Components of the ethyl acetate fraction obtained from C. halicacabum extracts were analyzed by TLC, HPLC chromatogram and LC/ESI-MS. Results showed that the ethyl acetate fraction contained some flavonoids, such as apigenin-7-O-glucuronide, apigenin-7-glucosdie and quercitrin hydrate. These results suggest that the extracts and fractions of C. halicacabum leaf may be applied as antioxidant functional cosmetic raw materials.

In this work, licorice extracts were prepared using various extraction conditions such as extraction solvent, temperature, and time from Glycyrrhiza uralensis (G. uralensis) produced in Korea and China and Glycyrrhiza glabra (G. glabra) in Uzbekistan. The optimum extraction condition was selected from the extraction yields and antioxidative activities of extracts. Korea licorice extracts showed the highest free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activity (46.05%) under the extraction condition of 85% ethanol at $60^{\circ}C$ for 6 hours. The prominent ROS (reactive oxygen species) scavenging activity using luminol-dependent chemiluminescence assay and the cellular protective effect against $^1O_2$ induced cellular membrane damage were also shown from the extracts obtained from the same condition. Especially, Korea G. uralensis extracts exhibited the higher prominent protective effect (${\tau}_{50}$ = 116.4 min) than (+)-(+)-${\alpha}$-tocopherol (${\tau}_{50}$ = 28.5 min) and the extraction yield of Korea licorice extract was 18.75%, which is 1.2 times and 2.5 times higher than that of Uzbekistan and China, respectively. These results indicate that the extraction condition of 85% ethanol at $60^{\circ}C$ for 6 hours is optimal to prepare licorice extracts, which can be applicable as anti-oxidative cosmetic materials.

In this work, comparative study on antioxidative activities of extracts from Glycyrrhiza uralensis (G. uralensis) produced in Korea and in China and Glycyrrhiza glabra (G. glabra) produced in Uzbekistan was conducted. Among three origins, 50% ethanol extracts (21.15 ${\mu}g/mL$), ethyl acetate fraction (29.15 ${\mu}g/mL$) and aglycone fraction (3.26 ${\mu}g/mL$) of G. uralensis from Korea showed the higher free radical (1,1-phenyl-2-picrylhydrazyl, DPPH) scavenging activity ($FSC_{50}$) than extracts from other origins. Reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) of extracts from three origins on ROS generated in $Fe^{3+}-EDTA/H_2O_2$ system were investigated using luminol-dependent chemiluminescence assay 50% ethanol extract (1.00 ${\mu}g/mL$) and ethyl acetate fraction (0.34 ${\mu}g/mL$) of G. uralensis from China showed the most prominent ROS scavenging activity. The protective effects of extract/fractions of G. uralensis and G. glabra extracts on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. 50% ethanol extract and aglycone fraction of G. uralensis and G. glabra extracts from three origins showed cellular protective effects in a concentration dependent manner (5 ~ 50 ${\mu}g/mL$). Aglycone fraction of G. uralensis from Korea (${\tau}_{50}$ = 847.4 min)especially showed cellular protective effects four times higher than that from China (${\tau}_{50}$ = 194.3 min). These results indicate that G. uralensis and G. glabra extracts, which have been used as whitening agent, could be applicable to functional cosmetic ingredient as a natural antioxidant. Judging from the prominent cellular protecitve effects, it is concluded that G. uralensis and G. glabra extracts can protect the skin from $^1O_2$ and various ROS induced by UV.

Purpose: To evaluate the correlation between cosmetic outcome (CO), body image, and quality of life in post breast-conserving therapy (BCT) women. Materials and Methods: This cross-sectional study concerned one-year post-completed BCT Thai women. The data included subjective and objective CO with a questionnaire covering demographic and clinical data, anti-hormonal treatment status, Eastern Cooperative Oncology Group (ECOG) performance status, Self-Reported Cosmetic Outcomes (SRCO), Self-Reported Breast Symmetry (SRBS), Body Image Scale (BIS), and the Functional Assessment of Cancer Therapy with Breast Cancer subscale (FACT-B). Participants had breast photographs taken for the evaluation of objective cosmetic outcome (OCO) after breast cancer conservation treatment. The relationship between CO and FACT-B was tested using Spearman's rank correlation Results: A total 127 participants volunteered for the study. The participant characteristics were age 52(${\pm}9$), Buddhist 87%, married 65%, body mass index 25.0(${\pm}4.6$), breast cup size A-C 91%, college educated 60%, employed 66%, ECOG 0-1 95%, tumor size less than or equal to 2 cm 55%, no lymph node metastasis 98%, and taking tamoxifen 57%. Two percent of the participants regretted their decision to undergo BCT. The SRCO was excellent in 2%, good in 68%, fair in 30%, and poor in 0%. For SRBS, rates were 17%, 58%, 24% and 1% for excellent, good, fair and poor cosmetic outcomes, respectively. The BCCT scores were excellent 24%, good 39%, fair 32%, and poor 6%. The median total QOL score of the participants was 130 (93-144). There was no significant correlation between CO and FACT-B scores. Conclusions: The significance of CO for FACT-B in Thai women with breast cancer could not be assessed in detail because of a very low level of correlation. The results may be due to the effects of cultural background.

In a previous study, we investigated the antioxidative and cellular protective effects of Parthenocissus tricuspidata stem extracts. In this study, we prepared nano-emulsion containing P. tricuspidata stem extract to improve skin permeation. The particle size of the nano-emulsion using the microfluidizer was 302 nm. Its loading efficiency was over 86%. The size distribution of the nano-emulsion took a monodispersed form and the nano-emulsion was more stable than typical emulsion without using microfluidizer during a 2 week period. In vitro skin permeation study of nano-emulsion containing P. tricuspidata stem extracts was carried out using Franz diffusion cell. The 1,3-butylene glycol used as a control group had 32.59% skin permeation efficiency. The skin permeation efficiency of the nano-emulsion was 42.47%. Also, we observed the antibacterial activity of the ethyl acetate fraction on skin flora for prospective applications as a natural antimicrobial. The ethyl acetate fraction had antibacterial activities higher than methyl paraben on Staphylococcus aureus, and Bacillus subtilis. These results indicate that nano-emulsion containing P. tricuspidata stem extracts could possess valued applications in cosmetic formulations for improving skin permeation. Also, based on the antibacterial activities on skin flora, antioxidative and cellular protective effects shown in our previous study, we suggest that P. tricuspidata stem extracts could be used as functional cosmetic materials.

This study focused on analyzing solid brown cosmetic residues that were excavated from the tomb of the Hwahyeop princess. The cosmetics had been buried in 1752 in Cheonghwa Baekja (small porcelain jars) within a Huigwakham (a stone box sealed with lime). A literature search and chemical analyses of the relics were conducted at the National Palace Museum of Korea. Based on the results of these analyses, raw materials and manufacturing methods for reproduction of the cosmetic were selected and then cream-form cosmetics were prepared. Aging tests using heat, ultraviolet (UV) radiation, and CO₂ were carried out to emulate the deterioration of the excavated cosmetics. Further chemical analyses and functionality tests were performed to evaluate changes from the tests and the effect as a cosmetic. As heat aging progressed, among the reproduced cosmetics, the one which has a high proposition of oil showed a color difference value of 32; the oxidation of oils involved chemical changes in O-H and C=C groups. As the cosmetic cream deteriorated under UV aging, the pH value became acidic. The result of the functional coverage test of the reproduced cosmetic cream was lower than the standard coverage ratio of modern cosmetics.

In this study, we investigated the antibacterial activity and the skin moisturizing effect of cream contaning Cedrela sinensis A. Juss shoots extracts. MIC values of ethyl acetate fraction from Cedrela sinensis A. Juss shoots extracts on P. acnes and S. aureus were 0.13 %, 0.03% respectively and P. ovale and E. coli were 0.25 % equally. The results showed that the antibacterial activity of the ethyl acetate fraction on P. acnes and S. aureus were higher than the methyl paraben. The cream containing the ethyl acetate fraction from Cedrela sinensis A. Juss shoots extracts was formulated and its skin moisturizing effect was evaluated in a clinical trial. The skin hydration and transepidermal water loss (TEWL) were investigated after topical application of the cream. The skin hydrating effect of the cream containing Cedrela sinensis A. Juss shoots extract was 10 ~ 15 % higher than the placebo cream, and transepidermal water loss was decreased to 6.7 g/$m^2h$ in the subjects applied with cream containing the ethyl acetate fraction of Cedrela sinensis A. Juss shoots extracts. These results indicate that ethyl acetate fraction from Cedrela sinensis A. Juss shoots extracts could be applicable to new functional antibacterial cosmetics.

We recently reported the characteristics of Chrysanthemum boreale MAKINO essential oil (CBMEO) at different harvesting stages and its in vitro antioxidant, whitening, skin regeneration, and antiwrinkle properties. In the present study, we investigated the effectiveness of cosmetic creams containing 0.1% of CBMEO in terms of wrinkle reduction and safety. The participants were 22 women aged 42 to 60 y with natural wrinkles. All the participants applied the CBMEO-containing cream to the eye area for 8 weeks. Visual observations of the skin by a dermatologist were used to assess the safety of the product, and improvements in skin wrinkles (roughness) were analyzed using a skin visiometer. Neither the CBMEO-containing cream nor the placebo caused abnormal reactions, such as erythema or allergies, during the test period. The CBMEO-containing cream-exposed test regions showed a greater reduction in the roughness index as compared with those of the placebo-exposed control regions. The R1, R2, and R3 indices showed a statistically significant decrease in the test regions as compared with the placebo control regions after using the cream for 2 weeks (p<0.05). Therefore, this study demonstrated that CBMEO-containing cosmetics are safe for human use and that they have skin wrinkle improvement properties. In the future, CBMEO may be a promising product for use in the development of functional anti-wrinkle cosmetics.

This study was conducted to investigate the possibility of peanut shell, a by-product of peanut, as a functional cosmetic ingredient. Peanut shell extract showed high antioxidant activity with IC₅₀ values of 75.00, 46.33, and 472.83 ㎍/mL for DPPH and ABTS radical scavenging and SOD-like activity, respectively. Furthermore, peanut shell extract was efficiently decreased the MMP-1 and MMP-3 protein level in the UVB treated-HaCaT cell and maintained procollagen protein level similar to normal control. Similar to anti-wrinkle related protein expression assay, the IC₅₀ value of elastase and collagnease inhibition in peanut shell extract was lower as 0.30 and 0.09 mg/mL, respectively, than that of the positive control. Additionally, eriodictyol and luteolin, which are isolated from peanut shell extract, showed 53.8 and 98.0% elastase inhibition rate, respectively, and 60.1 and 72.5% collagenase inhibition rate, respectively, at a concentration of 0.1 mg/mL. Thus, luteolin was assumed to be the effective ingredient for wrinkle inhibition in peanut shell extract. As a result of stability evaluation of lotion and cream formulations containing peanut shell extract, it was confirmed to be a stable formulation with no significant changes. Therefore, it is considered that peanut shell extract can be applied as a cosmetic ingredient for wrinkle inhibition.
