The purpose of this study is to offer basic data on cosmetics by investigating college women's purchasing and use behaviors regarding cosmetics according to their experience with side effects. A questionnaire was administered to 351 college women in the Seoul and Kyoung-in areas. The data were analyzed with SPSS Statistics V22.0 using frequency, ${\chi}^2$-test, and t-test. The results are as follows. First, 72.6% of surveyed women reported experiencing side effects from cosmetics. The largest side effects were acne and boils, and the primary ways of coping with these side effects were discontinuing use and using other products. Second, the group that experienced cosmetics' side effects used brands that were more expensive and eco-friendly than the group without side effects. Third, the group that experienced side effects continued to use the product more than the group without side effects. The primary reason for continued use was efficacy, and the reasons for discontinued use were efficacy and curiosity. Fourth, the side-effects group proactively identified cosmetics ingredients more than the non-side-effects group. Specifically, they checked the major components, the function, and for any hazardous ingredients. Fifth and finally, 98.3% of survey respondents purchased and used functional cosmetics. The group that had experience with side effects used more functional cosmetics than the group without side effects.

Skin disease is one of the most common diseases and its incidence is increasing dramatically in modern society. Specially, many attempts have been made to treat chronic skin inflammation diseases, such as psoriasis and atopic dermatitis, but effective therapies for the immune cell-mediated skin diseases, including psoriasis and atopic dermatitis have not been developed. Until recently, several drug candidates which were claimed to be effective for skin diseases have been reported, but most of them are not used to treat chronic skin disease. Especially, Psoriasis is characterized by excessive growth and aberrant differentiation of keratinocytes, but is fully reversible with appropriate therapy. The trigger of the keratinocyte response is thought to be activation of the cellular immune system, with T cells and various immune-related cytokines. Formation of new blood vessels starts with early psoriatic changes and disappears with disease clearance. Several angiogenic mediators are up-regulated in psoriasis development. Contact- and mediator-dependent factors derived from keratinocytes, mast cells and immune cells may contribute to the strong blood vessel formation of psoriasis. New technologies and experimental models provide new insights into the role of angiogenesis in psoriasis pathogenesis. TMP and its derivatives themselves effectively inhibited in vitro cell migration, tube formation, and the expression of angiogenic factors. However, TMP and its derivatives induced side effects including hemolysis and local side effects. Therefore, in an attempt to reduce the toxicity and the undesirable side effects of TMP and derivatives, a liposomal formulation was prepared and tested for its effectiveness. TMP and derivatives liposomes retained the effectiveness of TMP in vitro while side effects were reduced. These results support the conclusion that TMP effectively inhibits in vitro angiogenesis, with the possibility that use as a psoriasis relief agent.

It has been observed that local increase in melanin synthesis or uneven distribution can cause local hyperpigmintation or spot. Pigmentary disorders are caused by various factors, including inflammation, imbalance of hormones, and genetic disorder. Recently the harmfulness of Ultraviolet radiation is increasing due to destruction of ozone layer. Excessive exposure to UV radiation caused post-inflammatory pigmentation. Most women want to avoid uneven skin pigmentation. To satisfy this desire many cosmetic companies have been developing melanogenesis inhibitors and finding promising active agents for use in cosmetic preparations for skin whitening. In cosmetic preparations, many inhibitors such as kojic acid, arbutin, ascorbic acid, and licorice extracts6 have been used as whitening purpose. Plant extracts having an inhibitory effect on melanin formation may be a good choice for cosmetic purpose because of their relatively lower side effects. Therefore, we screened 285 plant extracts for their inhibitory activity in tyrosinase. Of the plant extracts, ramulus mori extracts showed potent tyrosinase inhibition activity. We also identified the active compound in the extract.

The customized cosmetics preparation management qualification system was implemented in March 2020, and it served to create jobs by developing professionals and vitalizing the cosmetics business. However, various problems such as high examination fees, suitability of questions, and utilization in industries are emerging. This paper attempts to prevent disputes that the system can cause and suggest ways to improve it by researching customized cosmetics, the industry status, and comparing foreign cosmetics laws. There is a kind of opinion that laws should be eased for this industry and the other opinion that expertise is necessary in this field because of safety. The system now has adverse effects due to a failure to adjust the difficulty of the exam. Cosmetics are not prescription-based, so they are routinely used. However, some toxic ingredients can cause side effects if they do not conform with certain standards. Also, it is difficult for a case to lead to lawsuits because most consumer damages related to cosmetics are individual. In addition, as e-commerce develops, there is a growing possibility of seeing more consumer damages. If safety and distribution issues, which experts are concerned about, escalate, the private dispute settlement system (among the ADR systems) should be activated as a resolution method.

Most people use cosmetics to protect their skin. Preservatives are often used to prevent their contamination upon use. There has been a great demand for natural preservatives due to recent reports on the side effects of parabens. Therefore, we evaluated the antimicrobial activities of Lonicera japonica and Magnolia obovata extracts and determined their potential as natural preservatives. We found that the 50% ethanol extract from L. japonica had antibacterial activity only against S. aureus and P. aeruginosa, while the ethyl acetate fraction showed antimicrobial activity against all six microbial strains tested. On the other hand, the 70% ethanol extract and the ethyl acetate fraction from M. obovata showed antimicrobial activity against all six strains. A synergistic effect against S. aureus, B. subtilis, and C. albicans was confirmed when two ethyl acetate fractions having antimicrobial activity against all six strains were used in combination. Synergistic activity against B. subtilis was also confirmed through kill-time analysis. High-performance liquid chromatography was performed to identify the components of each extract. Based on the minimum inhibitory concentration and the results of a disc diffusion assay, we confirmed that caffeic acid and luteolin influenced the antimicrobial activity of L. japonica and that the antimicrobial activity of M. obovata was influenced by the interaction of magnolol and honokiol with other components. Therefore, this study suggests that the combination of L. japonica and M. obovata extracts may be used as a plant-derived natural preservative.

The skin permeation study has two meanings in cosmetics. One is how to promote the skin permeation of active meterials for improving their bioavailabilities and the other is how to decrease it of irritants for reducing their skin side effects. In this study, we selected methyl paraben, one of the preservatives, as a model irritant and tried to reduce the skin irritation by the decrease of skin permeation. Furthermore, the relationship between skin permeation and skin primary irritation was discussed. For in vitro skin permeation experiments, Franz type diffusion cells and the excised skin of female hairless mouse from 8 weeks old were used. The donor compartment was charged with oil only or O/W emulsion containing 0.3% MP. We selected 19 oils, including esters, triglycerides, plant oils, hydrocarbons, and alchols, which are broadly used in cosmetics. We evaluated with female guinea pig. The skin permeahility of MP from the oils showed following order: ester oils > triglycerides > plant oils > hydrocarbons > alcohols. We considered that this result was based on the different effect of each oil on the barrier function of stratum corneum. In O/W emulsion containing each oil, the skin permeability of MP decreased as the oil/water partition coefficient of MP increased. The skin primary irritation increased as the skin permeability of MP increased. In conclusion, we suggest that the skin irritation could be reduced by the decrease of skin permeability of MP, which may be obtained by the good selection of oils in cosmetic preparations.
