The purpose of this study was to investigate the effect of usage behavior and usage satisfaction on the repurchase intention of facial skin care devices. A survey was conducted using a 35-question questionnaire among 356 women and the responses were statistically analyzed. Based on the results, skin type was classified into dry (3.4%), neutral (3.1%), oily (13.8%), combination (12.1%), sensitive (17.1%), and aging skin (20.8%). The most common skin type was combination 2, with 29.8%. Among the respondents, 63.8% answered 'yes' to 'repurchase intention', and the reasons were 'better than cosmetics use (33.3%)', 'easy skin care (32.3%)', 'good skin improvement effect (14.6%)', and 'time saving (13.0%)'. The most of wanted devices were LED mask (28.9%). The desired effects were elasticity, lifting (33.2%), and the improvement of skin tone and the reduction of blemishes (23.1%). ‘Neutral’ and ‘combination 1’ were shown to be significantly higher than other skin types in usage behavior, usage satisfaction, and repurchase intention (p<.001). A positive correlation was revealed between usage behavior and usage satisfaction (r=.464~633). Usage behavior and usage satisfaction were shown to have a significant effect on repurchase intention (p<.05). In conclusion, these results may be highly useful as basic data for the research and development of facial skin care devices. Women in China preferred the convex shape. For long hair styles, women in Korea did not like long hair without layers or with stumpy cut lines, which were favored among women in China.

Chenopodium album (C. album) is well-known for a medical plant and nutritions. The aim of this study is to examine the anti-wrinkles activity from C. album as a functional cosmetic material. Cell viability as the safety was measured in keratinocytes and fibroblast by MTT-assay. Production of procollagen type I and expression of Col Iαl mRNA, MMP-1, 2 mRNA were observed for anti-wrinkles effect. When observing stability and the effect of improving wrinkles with C. album as a functional cosmetic component, cell survival rate was turned out to be less reduced in the C. album ethanol extract in the amount of 50 ppm. Therefore, cytotoxicity seems to be minor. The C. album ethanol extract had the expression of Collage Iα1 and synthesis rate of pro-collagen I-type that were slightly lower than the TNF-β1, a positive-contrast substance, in the Hs 683. However, they were significantly higher than the control (p<0.05). The expression of MMP-1 mRNA, a collagen breakdown enzyme, was lower than the Vit. C 250 nM, a positive-contrast substance, but was similar with the control. However, the expression of MMP-2 mRNA was higher than the control and Vit. C 250 uM in the 10 ppm. Therefore, C. album ethanol extract promotes the synthesis of pro-collagen I-type and the expression of Collage Ia1 mRNA in the in vitro experiment and also is outstanding in suppressing the expression of MMP-2 mRNA, a collagen and elastin breakdown enzyme. Therefore, C. album ethanol extract is highly usable as a new cosmetic material for improving wrinkle. Hence, it is recommended to conduct more in-depth research in regard of elastin as well as concentration, dosage form, and collagen.
