When to See a Doctor. Although minor steam burns heal without a serious treatment, you may have to see a doctor when the wound doesn't heal in a few weeks. You should seek medical attention if the burn is extensive or you don't know how severe it is.  Length of healing time for burn wounds to heal depends on the depth and extent of the wound. First-degree burns heal quite quickly in usually less than 3 weeks. A Dr. Alexander Majidian, MD, Plastic Surgery, answered. The length of time it takes a burn to heal depends on how deep it is. In this video, Alexander Majidian, MD, FACS of the Grossman Burn Center at West Hills Hospital, discusses how long each degree of burn will typically take to heal. Your skin may peel in the area as it heals. Additionally, it may take three to 20 days for a first-degree burn to heal properly. Healing time may depend on the area affected. Always consult your doctor if the burn shows signs of infection or becomes worse. Tell us what you think. The pain and swelling may be mild and, after a day or so, your skin may start to peel. For a first-degree burn that occurs in larger areas of your skin, you may experience an increased level of pain and swelling. You may want to report large wounds to your doctor. Larger burns may not heal as fast as smaller burns Usually, partial-thickness burns heal in 10 days to 2 weeks. Large burns may take 3 to 4 weeks to heal. There may be little or no scarring if the burn was not too extensive and if infection is prevented. Do remember that blistering sunburns can cause skin cancer (melanoma) later in life.  Burns are defined as first-, second-, third-, or fourth-degree, depending on how many layers of skin and tissue are burned. The deeper the burn and the larger the burned area, the more serious the burn is. First-degree burns are minor burns on the first layer of skin. See an illustration of a first-degree burn. There are two types of second-degree burns: Superficial partial-thickness burns injure the first and second layers of skin. Read and follow any warning on the label. When a first-degree burn or minor second-degree burn is 2 to 3 days old, using the juice from an aloe leaf can help the burn heal and feel better. Applying the aloe juice may sting at first contact. It is important to protect a burn while it is healing If a small burn has been surgically closed with skin grafts, it may heal quickly. But larger wounds or more serious burns take up to three months or longer to heal. Again, burns may have varying depths, depending on the cause of the burn or the damage. One part of the burn injury may be a first or second-degree burn. A Dr. Alexander Majidian, MD, Plastic Surgery, answered. The length of time it takes a burn to heal depends on how deep it is. In this video, Alexander Majidian, MD, FACS of the Grossman Burn Center at West Hills Hospital, discusses how long each degree of burn will typically take to heal. Usually second-degree burns produce scarring. Second degree burns may take from one to three weeks to heal but are considered minor if they cover no more than 15% of the total body area in adults and 10% body area in children. These burns require medical attention and medication to heal properly.
