First-degree burns are red and blanche white when pressure is applied. There is no skin disruption or blistering, they involve only the outside layer of skin. Though painful, they take only two to five days to heal, and do not leave scars. Second-degree burns are also known as partial thickness burns. 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.
