For a small, mild skin burn, cool the area immediately under running water for 10?15 minutes (avoid ice), then gently dry and apply a soothing ointment like Silver sulfadiazine or a simple aloe vera gel. Keep the area clean and covered with a loose sterile dressing, and avoid bursting any blisters. If you notice increasing pain, redness, swelling, or signs of infection, or if the burn doesn?t improve, consult a doctor.
