|
This study was conducted to investigate the effect of human-derived urine on the 40-60s middle-aged
women’s neck skin. Two samples of 3-7year-old boy’s urine was used in freeze-drying after dialysis : one was
dialyzed urine in an instant and the other was dialyzed urine that was aged for three days. The subjects were
housewife in their 40-60s middle-aged women; a group of 10 students were selected for the dialyzed urine
group (DU), another group of 10 students for the group of the dialyzed after three days urine (DAU) and other
group of 10 students for the control group. The experiment had been conducted for a total of 8 weeks. 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 erythema index 13% (p=.009), melanin index 8% (p=.000), amount of
keratin 26% (p=.520), SCE a* (redness) 13% (p=.034), sebum content 56% (p=.089), and to increased SCE
L* (lightness) 4% (p=.278), SCE b* (yellowness) 6% (p=.072), Moisture 38% (p=.001). Besides, DUA group
also showed decrease in variation of erythema index 11%(p=.003), melanin index 9%(p=.021), amount of
keratin 40% (p=.284), SCE a* (redness) 9% (p=.034), sebum content 50% (p=.021), and to increased SCE L*
(lightness) 6% (p=.003), SCE b* (yellowness) 5% (p=.157), Moisture 43% (p=.001). Consequently, judging from
the changes in the DU group and the DUA group, it was confirmed that the ingredient of urine is very effective
in improving middle-aged women’s neck skin. The results of this research can be used to demonstrate the
