Try applying URINE to your skin. I know it sounds weird, but uric acid is one of the main ingredients in many skin care formulations because the skin loves it. And there is a ton of it in urine, obviously. You don't need to apply it everywhere, just pick a test spot, maybe a foot or a particularly troublesome patch. Pee on a cotton ball and apply the urine at least twice a day. Don't wash it off, just let it dry on the area. Do this for 1 week, and then decide if the urine has a positive effect. This is what I tell my kids for all their skin troubles, and it really works, I promise! For dandruff, try apple cider vinegar.
