If you’ve ever been to a Korean bath/sauna/spa and had a body scrub you’ll never forget the amazing amounts of dirt and grey rolls of dead skin that came off your body. The secret is the Korean Italy bath towel. You soak your body in water and, without soap, start to rub the towel/mitt over your body with just enough tension to rub off the dead skin. The green and red ones are the only ones that work—the pastel Japanese ones have a different texture and do not work as effectively. They sell them at any Korean grocery store, or you can find them online from Korea, and also on eBay.
