Seek medical help for burns if they are severe; on the face, hands, feet, or genitals; or bigger than 2 inches. For treating small minor burns at home, rinse the area under running cool water. Never use butter, grease, or powder on a burn. After rinsing, cover the burn with a thin layer of antibiotic ointment. Then bandage it. A nonstick dressing is best and you may need tape to hold the dressing in place.
