Second-degree burns are more serious than first-degree burns and usually have a blister. A second-degree burn occurs when the epidermis and dermis layer of skin are burned. It is recommended that if the second-degree burn is over more than ten percent of your body, you should seek medical treatment immediately.econd-degree burns generally heal in two or three weeks. Sometimes the burn will take more than three weeks to heal because of the size of the burn. Also, as the burn heals it will itch. DO NOT itch or scratch the burn. Itching and scratching could cause an infection.
Treat a first-degree burn as a minor burn unless it involves substantial portions of the hands, feet, face, groin or buttocks or a major joint. Second-degree When the first layer of skin has been burned through and the second layer of skin (dermis) also is burned, the injury is termed second-degree burn. Blisters develop and the skin takes on an intensely reddened, splotchy appearance. Second-degree burns produce severe pain and swelling. If the second-degree burn is no larger than 2 to 3 inches in diameter, treat it as a minor burn. If the burned area is larger or if the burn is on the hands, feet, face, groin or buttocks or over a major joint, get medical help immediately.
