The subjects were students in their 20s who have acne symptoms; 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.

On the other hand, DU group showed decrease in variation of sebum content (40%), amount of keratin (42%), erythema index (7%), blackhead (15%), amount of microorganism (51%) and acne grade level (68%). Besides, DUA group also showed decrease in variation of sebum content (27%), amount of keratin (40%), erythema index (9%), blackhead (16%), amount of microorganism (53%) and acne grade level (61%). 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 acne skin.
