The vigorous Korean washing procedure (known as "seshin") involves soaking the body in hot water and then exfoliating it with a "Korean Italy towel," a vibrant, thin loofah with a sandpaper-like texture, to remove all the grime, debris, and layers of dead skin that naturally build up on the body. As the ddemiri (scrub mistress) works, rolls of dark, grey skin peel off, revealing supple, pink layers of flesh beneath.
