The study aims to investigate the antecedents affecting purchase intention in the category of green skincare products. Many studies have used the theory of planned behavior to investigate factors affecting intention to purchase products in general. This paper not only retests the influences of attitude, subjective norm, perceived behavioral control on the intention to buy eco-friendly skincare products but also suggests a new antecedent - environment knowledge of purchase intention. More importantly, this study is the first to propose the moderating effect of country of origin and product knowledge on the relationship between attitude and purchase intention. This study employs a sample of 350 female customers from 18 to 39 years old in Ho Chi Minh City. The research applies the Multiple Linear Regression to analyze the proposed hypotheses in the conceptual framework and results in significant outcomes. The result shows that attitude is the most influential factor then, subjective norm, perceived behavioral control and environmental knowledge. Most importantly, the findings of this study suggest that product knowledge is found to moderate the effect of attitude on purchase intention. The finding of moderating effect is a new contribution to the literature and future research can be carried out to validate this result.

The purpose of this study is to predict skincare behavior from the perspective of theories about planned behaviors and a systematic structure for identifying influences on human behavior; Consequently, this study attempted to undertake a concrete analysis of influences on skin care behavior. The results showed that: an attempt was made to analyze structural equation modeling as to whether or not to apply Ajzen's theory of planned behavior to skin care behavior. This study found the possibility that the theory of planned behavior might be applicabled to the research model composed of skin care attitude, the norms of skin care, behavioral control on skin care, behavioral intentions of skin care, and skin care behavior at the appropriate level in their entirety. This study found that external control factors of skin care behavior had the highest effect on skin care behavior among other factors.

Objective : The aim of this study is to assess the effect of Korean Herbal Cosmetic on quality of life (QoL) of Korean Herbal Cosmetics Using Dermatology Life Quality Index (DLQI) stratified by blind versus non-blinded option.Methods : Forty five healthy females aged 30's to 40's were recruited for this study. Volunteers were divided into two groups : Group A (n=22) was provided an anti-aging cream with ginseng extract in the original packaging including the brand name and logo. Group B (n=23) were provided same cream in a plain white normal jar without any package decoration or logo.Results : All females except two volunteers in group A completed a DLQI questionnaire, baseline, after 4 weeks and 8 weeks of treatment. The baseline of DLQI scores of all groups was 3.23±2.72. There was a significant difference in DLQI scores between before, 4 weeks and 8 weeks after in both groups ; The scores changed from 4.25±3.45 to 0.95±1.15 at 4 weeks, 1.00±1.72 at 8 weeks in group A, The scores of group B changed from 2.35±1.47 to 0.83±1.23 at 4 weeks, 0.65±0.98 at 8 weeks. But both had no interaction effect between follow up times and groups. Subscale DLQI scores improved after 4weeks were 'Symptoms and feelings', only in group BConclusions : Both groups showed significant improvements in QoL quality scores evaluated by DLQI. However, interaction was not observed for whether the participants knew the brand and content of the cream.

Retinaldehyde (RA), vitamin A derivative, is an intermediate between retinol and retinoic acid and has an excellent wrinkle improving effect. In this study, Drug-in-cyclodextrin-in-liposome (DCL) was used to enhance the stability and skin penetration of RA. The complex of RA and hydroxypropyl-beta-cyclodextrin (HP-β-CD) was prepared by the freeze-drying method, and the presence or absence of inclusion of retinal was confirmed by UV-Vis spectrometer, FT-IR and SEM images. RA was captured in HP-β-CD about 95.6% on 1 : 15 (w/w). The retinal-HP-β-CD complex was encapsulated in liposomes using a homomixer and microfluidizer, with an average particle size of 215 ± 4.2 nm and a zeta potential of -31.2 ± 0.5 mv. In the evaluation of the degradation stability of RA, degradation rate of RA-HP-β-CD-liposomes in water was 1.8% higher than RA-liposome (5.8%), RA-HP-β-CD complex (9.7%) and RA alone (37.6%). RA cream (0.05% RA) including RA-HP-β-CD-liposomes was prepared for clinical test with wrinkle-improving efficacy and skin dermis denseness evaluated for 2 or 4 weeks. RA cream showed a significant wrinkle improving effect without skin irritation. In conclusion, it was confirmed that the double stabilization technology using the DCL system contribu tes to the effect of improving skin wrinkles by increasing the stabilization of retinal.

The ultraviolet blocking agents used to skincare are largely classified ultraviolet scattering agent and ultraviolet absorbent agents. There are UVC, UVB, and UBA in ultraviolet ray(UV) showing shorter wavelength than visible light. Both visible light and UVA give rise to 1st dark-skinned phenomena. On exposure of the skin to UV, phenomena of skin variation are termed sunburn or suntan. There are chronic and acute adverse reactions in skin response to UV. The latter is caused by UVB, which has mainly effects on the skin. But lately due to destruction of ozone layer, UVA has more serious irritation on the skin than UVB. In this paper spectrometric properties of UV absorbent agents such as PABA, octyl-PABA, Urocanic acid, and 2-hydroxy-4-methoxy benzophenone in vitro have been investigate. As results, it was found that the three fomer were more suitable than the last. UV scattering measurements on the sample used inorganic pigments showed that pigments containing titanium dioxide had a better scattering effects than the inorganic pigments such as $Fe_2O_3$, $Al_2O_3$, etc.

Due to the high UV light scattering effect of Zinc oxide (ZnO), it is frequently used in sunscreen skincare products. Recently ZnO coated with silica has been used in cosmetics to improve UV protection, texture, decreased photocatalytic activity, dispersibility and stability of the skin care product. In this study, we developed a ZnO composite powder coated with silica for the future application to skincare products to block UV rays that could cause photoaging. To improve consumer's satisfaction rating, we used ZnO microparticles which are widely used in the cosmetics industry. The silica was coated using hydrothermal method with sodium silicate and acid hydrolysis. UV protection of the composite powder was analyzed by UV-Vis and in-vitro test and the advantages for practical use of this powder as a skincare product were determined.

The objectives of this research were to investigate the relationship between purchase behavior and consumer dissatisfaction of cosmetics at internet shopping malls, and to examine how the purchase behavior and consumer values influence the consumer dissatisfaction. Subjects were 212 females in Seoul who had experiences of cosmetic shopping at internet shopping malls. Consumers showed highest dissatisfaction when the purchased cosmetics were different from the products showed at internet shopping malls. The dissatisfaction with consuming system was higher than buying system or transporting system. The higher the expense and frequency of cosmetic purchase, the lower the consumer dissatisfaction of buying system. Females of 18 to 24 years old purchased color cosmetics more than females of 25 to 39 years old did. Females of 25 to 39 years old purchased functional skincare products more than females of 18 to 24 years old did. The cosmetic purchase expense of older groups was higher than that of younger one. The more consumers spent time on the internet, the more frequent they bought the cosmetics at internet showing mall. Consumers were most willing to buy basic skincare products at the internet shopping mall (42.9%). The consumer dissatisfaction with cosmetics at internet shopping malls was influenced the most by the happiness value(-) and the next by the responsible value, the frequency of cosmetic purchase at internet shopping malls(-) in order.

The purpose of this study is to clarify of the distribution routes of cosmetics by their types and differences in choosing them according to ages with the ones in choosing brand by the type according to them. The subjects of the study were females aged 20 plus living in Seoul and Gyeonggi Province between January and February 2008, and 427 questionnaires were used for analysis. For data analysis SPSS 17.0 statistical program was used, and principal component analysis, frequency analysis, ${\chi}^2-test$, ANOVA test and Duncan test were conducted. The results and conclusions of this study are as follows: first, cosmetics store use by product type was examined. Department stores were used most often to purchase skincare, base and color products, while large cosmetics stores were used most frequently to buy hair and body products. Second, The result of the differences in choosing brand by type of cosmetics has found that there are the meaningful differences between Korean low and middle priced brands and foreign high priced ones in skincare and base products. The Korean low and middle priced brands of skin care products show that various distribution routes are simultaneously and highly used as choices in internet, cosmetics specialty stores and large general ones are higher than other distribution routes. Color products have found that there are the meaningful differences in the entire brands. Hair and body products have found that there are the meaningful differences in three brands except the Korean high priced brands. Third, the differences in cosmetics store selection by age were investigated. As for online purchasing, people in their 20's were most likely than other age groups to purchase online. Meanwhile, in case of other stores including door-to-door sales and home shopping, people aged 40 and older were more prone than other age groups to purchase base, color and body products through these stores.
