다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the effect of human-derived urine on the middle-aged women`s skin. The samples of 3-7year-old boy`s urine was used in freeze-drying after dialysis. The subjects were housewife in their middle-aged women ; a group of 10 students were selected for the dialyzed urine group (DU) and the other group of 10 students for the control group, which have general characteristics similar to the experimental group. The experiment has been conducted for a total of 8 weeks. When it comes to skin test, before the experiment and 8 weeks later after the first test, I measured the skin amount of keratin, melanin index, erythema index, pores, pigmentation and wrinkles aroud eyes. In the results of analysis, in the case of a control group were all increased or not changed. On the other hand, DU group showed decrease in variation of amount of keratin 32%(p=0.031), melanin index 11%(p=0.002), erythema index 10%(p=0.004), pores 17%(p=0.001) and wrinkles aroud eyes 17%(p=0.005). Consequently, judging from the changes in the DU group, it was confirmed that the ingredient of urine is very effective in improving skin. I want to provide the outcome of this research as the material that shows the possibility of the development of cosmetics that utilize urine derived from human beings.
