Example: I insisted on changing the dressing on his hand ,which was pussing and sloughing off burnt skin. Source: The Best American Travel Writing 2006 Background: A Chinese driver picked up an American traveler on the way to the holy city of Lhasa in Tibet for an annual pilgrimage. After a few miles, the driver smoked a cigarette. It wasn't until the American yelled at him that he realized one of the gloves was burning. He immediately rushed out of the car and stomped out the flames. His hand was burnt so severely that he wasn't able to drive anymore. The traveler applied a tourniquet to his hand and decided to replace him in the driver seat for the rest of the bumpy ride. Hi, Sloughing off burnt skin and shedding off burnt skin seem pretty close in meaning. Would "shedding off burnt skin also work fine in the example?
