Accidentally touching something hot, like grabbing a pan right out of the oven, or getting scalded with boiling water can burn your skin. Chemicals, the sun, radiation, and electricity can also cause skin burns.
Burns cause skin cells to die. Damaged skin produces a protein called collagen to repair itself. As the skin heals, thickened, discolored areas called scars form. Some scars are temporary and fade over time. Others are permanent.
Scars can be small or large. Burn scars that cover a wide surface of your face or body can affect your appearance.
