For individual red areas, apply 1% hydrocortisone cream to calm inflammation, he suggests. "The quicker you soothe inflammation, the less potential damage the skin will experience." As for any open wounds or raw skin, treat it the same way you would treat a thermal burn: Apply an over-the-counter antibiotic ointment like bacitracin ($5; amazon) to the individual area—this will form a protective seal and prevent it from getting infected, says Dr. Zeichner. But if you develop a blister, make sure to leave the roof intact because it protects the underlying raw skin from the environment and acts like a natural bandage, he adds.
