Whether bandaging is needed depends on the severity of the burn. Generally, if it's just simple redness, no bandaging is needed. After the local skin is scalded, if blisters form, it is considered a superficial second-degree burn. You can first rinse with cold water or soak in cold water for more than half an hour, or apply ice to reduce the pain. Before bandaging, clean the wound with hydrogen peroxide, then disinfect the wound surface with iodine, release the water inside the blister while keeping the blister skin, then apply burn ointment on the gauze, cover the wound surface, and then use multiple layers of dry gauze for bandaging. Generally, change the dressing every three days, and recovery can occur within two weeks, leaving no scars later. Patients should maintain a light diet, eat fresh vegetables and fruits, avoid spicy and stimulating food, and abstain from alcohol.
