Second-degree refers to a type of burn that affects both the outer layer of skin, known as the epidermis, and the underlying layer, called the dermis. This type of burn can cause redness, swelling, and blisters, and it is often painful. Second-degree burns can result from various sources, including hot liquids, flames, or chemical exposure. Treatment for second-degree burns typically involves cooling the burn with running water, covering it with a sterile bandage, and managing pain with over-the-counter medications. It's important to keep the burn clean to prevent infection. If the burn is extensive or shows signs of infection, medical attention may be necessary.
