Phytoestrogens derived from plants and foods, which are diphenolic compounds with structural similarities to natural and synthetic estrogens, have been shown to estrogenic and antiestrogenic actions. Particularly, recent study revealed that phenolic compounds in safflower seed, such as serotonin derivatives, lignans and flavonoids, could be acted as phytoestrogens. Safflower (Carthamus tinctorius L.) seed extract (SID C.SE), therefore, are receiving a renewed interest as potential therapeutic source against skin wrinkles induced by estrogen deficiency. This study was conducted to investigate the anti-wrinkle effect of SID C.SE on normal human fibroblasts through the expression of type I procollagen and UVA-induced MMP-1 in vitro. The SID C.SE increased the type I procollagen expression, comparable to trans-retinol and reduced UVA-induced MMP-1 expression in a dose-dependent manner. The clinical study indicated that cream group treated with $0.1\%$ SID C.SE significantly reduced a skin wrinkles, as compared with a control (non-treated cream group) (p<0.05). These results suggest that the safflower seed extract may be useful as potential source of anti-wrinkle cosmetics.

This review describes several kinds of emulsification methods for nanoemulsions and the application of nanoemulsions. Nanoemulsion droplet sizes fall typically in the range of 20 ~200 nm and show narrow size distributions. Although most of the publications on either oil-in-water (O/W) or water-in-oil (W/O) nanoemulsions have reported their formation by dispersion or high-energy emulsification methods, an increased interest is observed in the study of nano-emulsion formation by condensation or low-energy emulsification methods based on the phase transitions that take place during the emulsification process. Phase behaviour studies have shown that the size of the droplets is governed by the surfactant phase structure (bicontinuous microemulsion or lamellar) at the inversion point induced by either temperature or composition. Studies on nanoemulsion formation by the phase inversion temperature (PIT) method have shown a relation between minimum droplet size and complete solubilization of the oil in a microemulsion bicontinuous phase independently of whether the initial phase equilibrium is single or multiphase. Due to their small droplet size nanoemulsions possess stability against sedimentation or creaming with Ostwald ripening forming the main mechanism of nanoemulsion breakdown. An application of nanoemulsions is the preparation of nanoparticles using a polymerizable monomer as the disperse phase where nanoemulsion droplets act as nanoreactors, cosmetics and controlled drug delivery. In this review, we mainly focus on the cosmetics.

Recently, along with the remarkable increase in interest in microbiome cosmetics, the application of microbiome extracts in the complex efficacy as anti-aging, brightening etc. has become very important. In this study, Bifidobacterium bifidum (B. bifidum), which has excellent anti-wrinkle efficacy among the microbiome, was selected through an in vitro test using cells and 3D human skin equivalents. And the anti-wrinkle efficacy of cosmetics containing B. bifidum was evaluated by clinical test. Thereafter, the cytotoxicity, anti-oxidation, anti-inflammatory and anti-wrinkle efficacy of the of the bifida fermented filtrate were tested. An emulsion containing bifida fermented filtrate at a concentration of 5% (v/v) with no cytotoxicity and excellent efficacy was prepared with the placebo emulsion. The clinical test was conducted on a total of 21 women at 2 weeks comparing the bifida emulsion and placebo emulsion. Wrinkles around the eyes were instrumentally evaluated using Antera 3D. The wrinkle reduction rate of the Bifida emulsion group compared with the placebo emulsion group differed by 5.6%. Overall, the selection of microbiome using 3D human skin equivalents and the efficacy study of cosmetics with the microbiome extracts would be actively studied to the development of microbiome cosmetics and skin microbiome mechanisms.

Background: Along with the increase in consumer interest in and consumption of tattoo products, the controversy over harmful heavy metals associated with the use of tattoo cosmetics is also increasing. Therefore, investigation of hazardous metals in these tattoo products is needed. Objectives: This study was performed to provide useful data for establishing reasonable standards to securely manage tattoo cosmetics, tattoo stickers, and tattoo inks distributed in the market. Methods: Thirteen kinds of hazardous metal contents (Pb, As, Cd, Sb, Ni, Co, Cu, Cr, Se, Ba, Zn, Sn, and Hg) were analyzed for 23 tattoo cosmetics, ten tattoo stickers, and 16 tattoo inks. Hg was measured through the combustion-gold amalgamation method, and other hazardous metals were measured by inductively coupled plasma-mass spectrometry (ICP-MS) after acidic decomposition using a microwave apparatus. Results: The detected ranges of Pb, As, Cd, Sb, Ni, and Hg in tattoo cosmetics were 0.07~1.18, 0.06~0.41, ND~0.07, 0.01~3.44, 0.12~2.75, and ND~0.01 ㎍/g, respectively. All of the hazardous metals detected were below the recommended maximum standards of the Ministry of Food and Drug Safety. The mean amount of Pb detected in tattoo stickers for children was 0.24 ㎍/kg and Cd was not detected, meaning both metals met the recommended criteria. There was no statistically significant difference in all measured metals between children's tattoo stickers and adults' tattoo stickers. In the results of the study on the hazardous metal content of tattoo inks, four products (25%) for Pb, one product (6%) for As, 13 products (81%) for Ni, four products (25%) for Cu, and five products (31%) for Zn exceeded the recommended standards approved by the government. The highest predicted exposure amount for hazardous metals exceeding the recommended level of tattoo inks in a single tattooing was 5.69 ㎍/kg for Ni, 8.51 ㎍/kg for Zn, 0.44 ㎍/kg for Pb, 8.07 ㎍/kg for Cu, 0.44 ㎍/kg for As, and 71.36 ㎍/kg for Ba. Conclusions: It is necessary to prepare criteria for content limitation for the management of Co, Cr, Ba and Se tattoo cosmetics, and tattoo inks require thorough quality control.

The purposes of this study were to categorize female consumers based on appearance satisfaction and to examine the differences among the categorized groups on appearance types and appearance perceptions (appearance interest, stress related to appearance, and the extent of cosmetics use). A total of 518 responses collected from a questionnaire survey to female consumers was analyzed. Cluster analysis on appearance satisfaction identified four groups including the types of: Feature satisfaction(32%); Skin satisfaction(31%); Dissatisfaction(19%); and Overall satisfaction(16%). Chi-square and ANOVA analyses revealed significant differences among the four groups on the 6 appearance types (face line, face size, skin tone, skin blemish, skin elasticity, and wrinkles) and the stress related to appearance.

Drugs mean not only medicines but also poisons, pesticides, food additives, cosmetics, cleaning agents, environmental pollutants and so on, which are normally considered foreign to the body, It is important to know what happens to these drugs when they get into the body. In the past the metabolic changes of drugs had been referred to as “detoxication mechanism”, but since there are many instances in which drugs are converted in the body to more active substances. Thus, metabolism of drugs is responsible for activation and inactivation of the drugs in the body. The major reactions in drug metabolism are oxidation, reduction, hydrolysis and conjugation. Of these four areas, most of the attention had been focused on the oxidation. Therefore, in contract of ample literatures on drug-oxidizing enzymes, there were relatively few reports on drug-reducing enzymes. In recent years, however, the reduction has received an increasing interest due to its pharmacological or toxicological significance. The present lecture is organized keeping with a focus on drug-reducing enzymes which have been explored by us and by other groups.
