Purposes: This is a study on the perception of safety in use according to cosmetic information. Research design, data and methodology: As a result of analyzing 324 women in their twenties living in the metropolitan area, the following conclusions were drawn. Results: As a result of measuring the awareness of cosmetic information, the awareness of 'cosmetic-related knowledge' (M=3.52) and 'cosmetic performance' (M=3.43) was high, indicating that information on cosmetic knowledge was actively shared with each other. It was understood that the method of use and effect were properly recognized and that the cosmetics were selected. 'Correct cosmetic storage method' is significant in the factors of interest in cosmetics (p<.001), and 'the harmful ingredients of cosmetics that should be avoided' are significant in the factors of cosmetic information (p<0.05) and the factors of interest in cosmetics (p<0.01). 'Trouble-causing ingredients' showed a statistically significant difference in safety perception in all factors except cosmetic performance factors. Conclusion: There is a need to construct a system that allows consumers to easily purchase cosmetics that are necessary for their skin by schematically or simplifying the information on the usage period and trouble-causing ingredients after opening the cosmetics to be easily understood.

In 2022, the domestic production performance of functional cosmetics in South Korea reached 4.6 trillion won, accounting for 33.85% of the total cosmetics production. The number of functional cosmetics reviewed increased by about 7.5% from the previous year, totaling 974 items. Especially with the increasing importance of the skin barrier function due to skin sensitivity caused by various environmental pollutants, domestic cosmetic companies are showing interest in the development of new ingredients and products related to this area. This study aims to analyze academic research trends related to in vitro experiments for the development of cosmetics improving the skin barrier, to provide practical information for the cosmetic industry. The findings are as follows: Academic research mainly focused on the efficacy of natural ingredients in improving the skin barrier, but there is a significant lack of quantitative accumulation of research. For the development of skin barrier-improving cosmetic ingredients, efficacy evaluation indicators were set, including hyaluronic acid production, expression of filaggrin gene, loricrin, formation of cornified envelope (CE), and expression of ceramide synthesis enzyme genes. Moreover, effective cosmetic ingredients for improving the skin barrier included lemongrass and perilla leaf extracts, flavonoids, Lactococcus lactis subsp. lactis, Exosomelike Nanovesicles derived from apple callus, Eleutherococcus sessiliflorus, Acanthopanax sessiliflorus, Eleutherococcus gracilistylus, Acer okamotoanum extracts, Aloe vera adventitious root extract, ethanol extract of Aruncus dioicus, and organic solvent fraction of Dracocephalum argunense.

Functional cosmetic ingredients such as L-ascorbic acid, retinoic acid, indole-3-acetic acid, salicylic acid, acidic dye(indigo carmine) are intercalatively encapsulated by skin-friendly metal hydroxides and oxides matrices. Such functional organic-inorganic nanohybrids are realized via chemical coprecipitation and surface coating reactions. The hetero-structural nature of these nanohybrids, their particle morphology and textural characterizations are mainly discussed on the basis of powder X-ray diffraction, electron microscopies, and high performance liquid chromatographic analyses. The cosmetic ingredients encapsulated in inorganics show greatly improved storage stability, sustained releasing property as well as higher transdermal transfer efficiency.

Unstable cosmetic active ingredients could be degraded rapidly by chemical and photochemical process. Particularly, some of active ingredients like retinol are known to cause skin irritation when applied on the skin excessively. Therefore, it has become a very important issue to encapsulate cosmetic actives for the stabilization and skin protection. This study was performed in order to prepare a chitosan microcapsule containing liposoluble cosmetic actives and to investigate the stabilization effect of actives when chitosan microcapsule was applied in cosmetic formulation. Chitosan, deacetylated form of chitin, has been of interest in the industrial applications due to its biocompatibility, biodegradability, non-toxicity, antimicrobial activity and also used as a wall material of capsule. Retinol was used as a core material and was stabilized by a wall of chitosan and antioxidants. The chitosan microcapsule containing retinol(CMR) was prepared by using coacervation method and W$_1$/O/W$_2$ emulsification techniques. The CMR has 0.5~10.0 ${\mu}{\textrm}{m}$ size distribution and a long-term stability of more than an year inside the cosmetic formulation(O/W). Remaining retinol percentages at 45$^{\circ}C$ after 8 weeks in the CMR dispersion were 15.6%(pH 4.0), 59.8%(pH 6.0) and 65.0%(pH 6.0 with antioxidant) respectively. Retinol stability when added CMR inside a ONV emulsion was better than that of ONV emulsion added non-capsulated retinol. As a result, remaining retinol at 45$^{\circ}C$ after 8 weeks in O/W emulsion added non-capsulated retinol and O/W emulsion containing CMR was 12.7%, 70.5% respectively. It appeared that chitosan treated microcapsule may be used for a potential encapsulation method of unstable active ingredients.
