In this study, we investigated the total phenolic and flavonoid contents, antioxidant activity and cellular protective effects against oxidative stress on human skin cells in 50% ethanol extract and its fractions of Calendula officinalis (C. officinalis) flowers. We measured the antioxidant effects of 50% ethanol extract and its fractions of C. officinalis flowers on the free radical scavenging activity ($FSC_{50}$), the reactive oxygen species (ROS) scavenging activities ($OSC_{50}$) and the inhibition of intracellular ROS generation in human skin cells. These results showed that the antioxidant effect of the ethyl acetate and aglycone fraction was more than the 50% ethanol extract of C. officinalis flowers. We also investigated the cellular protective activity and the results showed that treatment of the ethyl acetate fraction ($0.05-3.13{\mu}g/mL$) protects human skin cells in a concentration-dependent manner when the skin cell damages were induced by treating them with $H_2O_2$. In addition, the aglycone fraction ($1.56-3.13{\mu}g/mL$) shows cellular protective effects on the UV-induced cell damages in a dose-dependent manner. These results suggest that the fractions of C. officinalis flowers can function as a natural antioxidant agent of cosmetics in human skin cells exposed to oxidative stress by ROS scavenging effects.

Inflammation caused by active oxygen and the resulting barrier damage have been consistently pointed out as the cause of wrinkle formation. In this study, effective index ingredient search and efficacy analysis were performed to verify the value of use as a functional cosmetic material related to antioxidant, anti-inflammatory and skin barrier improvement, and anti-aging for extracts of four types of Eleutherococcus divaricatus var. chiisanensis (ED), Eleutherococcus senticosus (EN), Eleutherococcus sessiliflorus (ES), and Eleutherococcus sieboldianus (EI) belonging to the Eleutherococcus genus. To identify the effective index composition, the content of the ingredients was measured by high-performance liquid chromatography. The content of eleutheroside E and chlorogenic acid was the highest in ED among the Eleutherococcus genus. As for anti-oxidant activity, DPPH radical scavenging activity was the highest in ED. In anti-inflammatory effects, ED extracts inhibited nitric oxide generation in inflammatory macrophage cells due to lipopolysaccharide by 40% at 100 ㎍/mL. In the case of IL-6 inhibition, which is known as a pro-inflammatory cytokine, ED showed 41% inhibition at 100 ㎍/mL. In addition, filaggrin and involucrin, which are skin barrier-related factors, were increased by 2.5 times and 1.6 times, respectively, in 100 ㎍/mL of ED extracts, and as for the collagenase, which is a wrinkle-related factor, ED extract showed 29% efficacy at 100 ㎍/mL. Thus, these result suggested that ED extract, among the four Eleutherococcus genus, can be used as a cosmetic ingredient for suppressing inflammation in the skin, reinforcing the skin barrier, and reducing wrinkles.

Platycodon grandiflorus (P. grandiflorus) flower is a perennial plant belonging to the family Campanulaceae and has many excellent pharmacological effects, so it has been used as a medicinal ingredient since ancient times. In addition, anthocyanin is a purple or blue natural pigment contained in plant flowers and fruits, and is known as a powerful antioxidant. The purpose of this study was to confirm the dermatological functionality of P. grandiflorus flower extract and the value of the bluish anthocyanin contained in flowers as a cosmetic material as a natural pigment. Firstly, 50% ethanol and 80% ethanol were added to the P. grandiflorus flower and extracted under reflux for 4 h at 25, 60, and 80 ℃, and the pH of each treatment group was similar. Based on the anthocyanin content and chromaticity (E^*ab), 50% ethanol 60 ℃ extraction conditions showing the color development most similar to the natural color of the P. grandifloras flower were selected, and a sample was prepared by concentrating and lyophilizing. The analysis results showed that the total phenol, total flavonoid, and total anthocyanin contents were in the ranges of 23 ㎍/mL, 16 ㎍/mL, and 0.17 ㎍/mL, respectively. The P. grandiflorus flower extract suppressed the production of nitric oxide (NO) and interleukin-6 (IL-6) in lipopolysaccharide (LPS) induced RAW264.7 cells. Furthermore, the P. grandiflorus flower extract showed wound healing effects through the promotion of skin cell migration in TNF-α stimulated human keratinocytes. The stability of anthocyanin and extract color was studied during a storage period of 50 days at various temperatures (4 ℃, 25 ℃, and 45 ℃). Color values (L, a, and b) of the P. grandiflorus flower extract changed over 50 days, whereas the bluish-purple color of the extract was stabilized using 5% maltodextrin. These results suggest that P. grandiflorus flower extract may be useful as a natural cosmetic pigment.

In this paper, we present the improvement in low moisturizing ability and stability that existing skin softeners have due to the low oil content, by developing skin softener using nanoemulsion of phospholipid liposome, based on the properties of nanoemulsion in cosmetic formulation. In this study, two types of oil; dimethicone (DC 200/6cs) or medium chain triglyceride (MCT), and two kinds of lecithin; unsaturated or saturated were respectively applied to produce nanoemulsion. In the particle size analysis of nanoemulsion, the droplet size of nanoemulsion containing DC200/6cs and unsaturated lecithin was the smallest, and all nanoemulsion showed high stability in the measurement of zeta potential. Therefore, with the smallest particle size and high stability, moisture contents and trans epidermal water loss(TEWL) were measured using the skin softener of DC200/6cs and unsaturated lecithin contained nanoemulsion, and the measurement was compared with the non-oil skin softener and the skin softener with only small amount of oil. The results showed that the moisture content of the skin softener using nanoemulsion increased greatly than other two skin softeners, showing high hydration ability and water retention capacity, and TEWL decreased greatly, therefore preventing the evaporation of moisture from the skin. As a result, the oil content and stability of the skin softener was improved by utilizing nanoemulson based of phospholipid liposome, and it is expected to be used in various ways in cosmetic industry.

The traditional feminity has gradually been diversified in the 21th century due to a change in the society. This diversification of women's images and styles is derived from the addition of masculinity to feminity. C. G. Jung insist that human being is bisexual in nature. Animus is the male aspect in the women's collective unconscious and it is the archetype through which we generally communicate with the collective unconscious. It is also important to get into touch with the collective unconscious for self-realization. This study analyzes subconscious desires based on the Animus archetype in the collective unconscious of women through the diversity of the gender identity shown in cosmetic advertisements. Therefore this study aims to suggest a marketing strategy for the women's beauty industry in the future. For this purpose, this study conducts an empirical analysis of women's make-up and hair style in cosmetic advertisements through the Jungian Animus theory. The conclusion of this study is as follows: First, gender identity represented in cosmetic advertisements was classified into Mother/Wife, Hetaira, Mediale and Amazon. Second, the Animus archetype stimulates masculinity in women's make-up and hair style. Third, range of utilization of cosmetic products is articulated with the diverse gender identity. This masculinization of women's beauty style is the external expression of collective unconscious and affords human being to reach self-realization.

Purpose - Based on complexity theory, this study develops a configurational model to predict the profitability of Halal cosmetics firms in the Indonesian and Malaysian markets. The proposed research model involves two level configurations-industry context and selling strategies-to predict high and low scores of a firm's profitability. The industry context configuration model comprises industry stability, product homogeneity, price sensitivity, and switching cost. Selling strategies include customer-focused, competitor-focused, and margin-focused approaches. Design/methodology - This is the first empirical study that calculates causal models using a combination of industry context and selling strategy factors to predict profitability. Data obtained from the marketing managers of cosmetics firms are used to test the proposed configurational model using fuzzy-set qualitative comparative analysis (fsQCA). It contributes to the current knowledge of business marketing by identifying the factors necessary to achieve profitability using analysis of condition (ANC). Findings - The results revealed that unique and distinct models explain the conditions for high and low profitability in the Indonesian and Malaysian halal cosmetic markets. While customer-focused selling strategy is necessary to attain a higher profit in both the markets, margin-focused selling strategy appears to be an essential factor only in Malaysia. Complexity of the interactions of selling strategies with industry factors and differences between across two study markets confirmed that complexity theory can support the research configurational model. The theoretical and practical implications are also illustrated. Originality/value - Despite the rapid growth of the global halal industry, there is little knowledge about the halal cosmetic market. This study contributes to the current literature of the halal market by performing a set of asymmetric analytical approaches using a complex theoretical model. It also deepens our understating of how the Korean firms can approach the Muslim consumer's needs to generate more beneficial turnover/revenue.
