These burns can be caused by hot objects, hot liquids, steam, or the sun. First-degree burns are red and blanch white when pressure is applied. There is no skin disruption or blistering, because they involve only the outside layer of skin. Though painful, they take only 2 to 5 days to heal and do not leave scars. Burned skin is a mottled red and pink, and weepy.
Blisters are present.
Superficial second-degree burns are quite painful, and heal within one to two weeks without scarring. Deeper second-degree burns are less painful, but may take several weeks to heal. They often leave scars. If you witness a burn, or burn yourself, the sooner you act, the better. First, immerse the affected area in cool clean water.
