Bacteria is constantly forming on the outer layer of your skin. It is looking for a way to invade your body. Your body reacts by simply throwing away the outer layer of your skin. It does that a cell at a time, but it does it constantly. Those cells must be replaced. To do that, the cells underneath must constantly reproduce and create new skin cells.
