In this study, the moisture content of the face skin was changed according to the number of skin applications for female college students under 25 years of age. Moisture contents were measured using a skin moisture meter (skin oil and moisture meter, PRC, China). Skin used 500ml of Innisfree's blueberry rebalancing skin as a clinical trial material. Both the forehead, eyes, cheeks, and chin had a higher moisture content after one layer of application than before and after one layer of application, and after ten layers of application, it can be seen that the moisture content is higher. As a result, when applying basic products after washing your face, the first step is to increase the number of skins, and then apply basic products such as lotion and moisturizing cream to increase the moisture content.

The study examined the effects, strength, and weakness of chemical peeling and physical peeling, which are some types of peelings that are commonly used for cosmetic skin management for women. For this study, of which the study period was from November 1 to December 27, 2011, 20 female subjects with the compound skin type were investigated. Ten women were assigned to the chemical peeling group, and the other 10 were assigned to the physical peeling group. The experiment continued for six weeks, with one test session per week, totaling six tests. During each session, a skin measurement instrument was used to measure the oil, keratin, pore, wrinkles, and pigments. The results of the tests showed that, in the case of chemical peeling, both glycolic acid peeling and lactic acid peeling were effective in preserving the skin moisture. With physical peelings, crystal peeling was more effective on wrinkles, while diamond peeling was more effective in keratin and pigment improvement. A comparison of the peeling with different media revealed physical peelings to have more effect on more items, but chemical peeling was more effective in moisture and oil changes.
