Answer
Temperature is higher at a person's core and lower at the surface of the skin. Because of this, proteins with low solubility at low temperatures will precipitate inside the vessels in the skin. These proteins build up and block the blood flow to the vessel. This prevents oxygen delivery and kills the cells nearby.
