I have recently learned from a program on Arirang TV that lower-class Korean women in pre-modern times (and currently in some remote areas) maintained beautiful skin by washing their faces every night with their own urine (women with money would wipe their faces with sesame oil and honey). Apparently modern dermatologists have verified the scientific validity of this seemingly disgusting practice. As it turns out, urea helps retain moisture in dry, chapped skin.
So if I happen to urinate on your face, keep in mind it’s not an act of violence but skincare. Let ‘er rip!
