No, urine is not a waste product, it contains hormones, enzymes, it can rejuvenate the skin, it restores the pH balance perfectly and eliminates wrinkles. The cleaner your body is, the better quality your urine is, of course. It has been used for centuries in oriental medicine. Rinse your skin, leave it on for 5 minutes or more if you have time, then follow with distilled water (or just boiled water, tap water is too hard). If you have oily skin but it is still dry, maybe it was caused by harsh cleansers. Kefir, as somebody has already mentioned, will help you to restore your intestinal friendly bacteria. Stick to a simple vegetarian diet during your cleansing process. Antibiotics and birth control pills kill the friendly intestinal flora, if you want to restore it, avoid these chemicals.
