What is urine good for? Can I use it as a moisturizer?
assistant
There’s no medical or health benefit to using urine as a moisturizer. Urine is primarily a waste product of excretion from the kidneys, and is primarily composed of water, urea, salts, trace elements and other metabolites. Pregnant women and children with kidney problems can use urine to moisturize the skin, but this should be administered under a physician’s supervision. Otherwise, urine testing is the main clinical use of urine. Human urine can also be used as a source of biofuel, or as an animal repellent.
