This objectives of this research was to look into the actual state of fashion wearing purchase and makeup purchase to recognize the interrelationship between fashion and makeup styles by selecting words used for fashion image and cosmetic style. Such study can offer basic materials for choice of makeup style by each fashion style. Most information on fashion and cosmetics were obtained through the internet. However, a lot of information on cosmetics were also obtained through TV. Therefore, if fashion companies use both internet and TV for advertising, more effect on purchasing might be obtained. The design and color are important standards for selecting clothes. However, the quality and price of clothes are essential standards for purchasing cosmetics. Therefore, for fashion companies, they need to pay more attention to design and color. However, for cosmetic companies, they need to take notice of quality and price. When image words were extracted, fashion images showed the following words: natural, romantic, elegance, casual, and avant-garde, while makeup images showed romantic-casual, elegance, avant-garde, and natural. Regarding the interrelationship between fashion style and makeup style, natural and casual fashion style were harmonized with natural makeup while romantic fashion style was associated with romantic makeup. The fashion style of elegance and avant- garde was associated with elegance makeup. Therefore, similar images were found between fashion and makeup styles.

UV irradiation on a skin brings about the qualitative and quantitative alterations of the extracellular matrix. Repeated-UV irradiation suppressed the synthesis of collagen and activated the expression of the matrix metalloprotease (MMP). In this paper, on the purpose of development of novel anti-aging agents from natural sources, effects of several natural products on in vitro MMP-1 activity and UVA induced MMP-1 synthesis in human dermal fibroblast (HDF) culture were studied. We measured MMP-1 activities by fluorescence assay using gelatin as substrates. As a result, the extract of Dicentra spectabilis, and flower buds of Tussilago farfara showed strong inhibitory effect. Among them, the extract of flower buds of Tussilago fartara and Dicentra spectabilis inhibited MMP-1 activity by 92% and 87% at 0.05% (w/v). And UVA induced MMP-1 expression were analyzed by enzyme-linked immunosorbent assay (ELISA) and gelatin-based zymography in HDF culture. The extract of flower buds of Tussilago farfara and Dicentra spectabilis suppressed the UVA induced expression of MMP-1 by similar level of Vitamin C 200$\mu$M at 0.1% (w/v). These results suggest that the extract of Dicentra spectabilis, and flower buds of Tussilago farfara effectively prevent skin from the UV-induced photoaging. So the extracts are thought to have potential as effective raw materials for anti-aging cosmetics.

Recently, consumers using cosmetics have a great interest in raw material safety. Among them, interest in natural preservatives is increasing, and as the demand for cosmetics excluding paraben preservatives increases, a method of replacing synthetic preservatives with antibacterial essential oils is being considered. The antibacterial effect of essential oils depends on the components, concentrations and interactions between the main active compounds. Effective preservatives should have antimicrobial activity against a wide range of strains even at minimal concentrations. All preservatives should be considered to increase skin concentration and cause skin irritation and allergic reactions. Consumers recognize that essential oils from nature are safe, but some should be careful because they can cause contact allergies or phototoxic reactions. As such, it is important to balance natural preservatives with maximum preservative effects and low toxicity. This paper describes the characteristics of essential oils focused on antibacterial properties, efficacy and safety as cosmetic preservatives.

Cosmetics using natural materials which was purchased in retail stores, distributed in Gyeonggi province(32 samples) and online through internet(24 samples) were analyzed by pesticide residues and target preservatives for assessing the safety of it. Natural or organic certifications was identified in 22 samples among 56 samples and most of them were Ecocert. Pesticide residues was detected in 3 samples among 56 samples and each compound and concentration was permethrin(0.6 mg/kg), tricyclazole(11.7 mg/kg) and malathion(0.05 mg/kg). All of it was purchased through internet. Target preservatives was detected in 13 samples among 56 samples and one of them was over the maximum allowed concentration and the rest of them were within the maximum allowed concentration of the respective preservatives. The compound which was over the maximum allowed concentration was benzoic acid and compounds which were within the maximum allowed concentration were sorbic acid, benzoic acid and methylparaben. They were all identified substances in products and the number of detected preservatives in retail stores were higher than online samples purchased through internet. As a result of this study, The method of analyzing pesticide residues and limit in cosmetics using natural materials should be set up as soon as possible and the monitoring about preservatives in cosmetics using natural materials should be conducted on continuously.

Objectives : Since cosmetics have been one of the help of life, unlike medicine, natural products have been used for cosmetics, generally giving the image of safety and relief compared to synthetic products. Among them, Houttuynia cordata has been known as a useful herbal medicine with antibiotic, anti-inflammatory and anti-oxidative activities. In this study, we were to use Houttuynia cordata extract on formulation of cosmetic emulsions. Methods : The effects of Houttuynia cordata extract on emulsion stability and viscoelastic properties of emulsion were measured using turbiscan and rheometer. And we assessed the anti-oxidative and antibiotic activities of Houttuynia cordata extract. Results : 1. The results of this investigation for emulsion stability showed that the stability emulsion containing Houttuynia cordata extract was decreased depending on concentration of Houttuynia cordata extract. 2. Super oxide dismutase activity was strongly dependents on concentration of Houttuynia cordata extract. 3. Houttuynia cordata extract showed good anti-microbial activity against Staphylococcus aureus. Conclusions : Houttuynia cordata extract can be effectively used in cosmetic emulsions when the relation between natural product extracts and formulation of cosmetics is elucidated.

Due to social phenomena such as rapid aging in Korea, nuclear familyization, single marriage, and low birth rate, the number of Companion animals and the number of households with Companion animals are increasing due to the increase in single-person households. In fact, one out of every four households has a pet, and the scale of the industry is expected to reach 6 trillion won in 2027. In particular, in a situation where the Companion animal cosmetics market is in the spotlight amid the diversification of the pet industry, there is a great lack of research on related research and industry development methods. Accordingly, this study attempted to search and analyze academic data, patented technologies, and the latest data related to pet cosmetics and provide them as basic data for the Companion animal cosmetics industry, and the results are as follows. Academic data included verification of the effectiveness of natural materials to improve the skin condition of dogs, analysis of the pet cosmetics industry, and research on ICT-converged pet cosmetics, and the industry was mainly cleaning cosmetics, with pet shampoo launches in Amorepacific, LG Household & Healthcare, and Aekyung. In the patented technology for pets, a patent has been registered for natural product material composition and formulation ratio for skin moisturizing, skin improvement, thinning, and inflammation symptom relief. As a result of this award, it was confirmed that research and development are still insufficient compared to the consumption demand of the pet cosmetics market, and it is believed that industry analysis and development research in related fields should be actively carried out.

We investigated the inhibitory effects of hesperidin on melanogenesis. To find melanosome transport inhibitor from natural products, we collected the structural information of natural products from Korea Food and Drug Administration (KFDA) and performed pharmacophore-based in silico screening for Rab27A and melanophilin (MLPH). Hesperidin did not inhibit melanin production in B16F10 murine melanoma cells stimulated with ${\alpha}$-melanocyte stimulating hormone (${\alpha}$-MSH), and also did not affect the catalytic activity of tyrosinase. But, hesperidin inhibited melanosome transport in melanocyte and showed skin lightening effect in pigmented reconstructed epidermis model. Therefore, we suggest that hesperidin is a useful inhibitor of melanosome transport and it might be applied to whitening agent.
