What are the classifications of burns? Burns are classified as first-, second-, or third-degree, depending on how deep and severely they penetrate the skin's surface. First-degree (superficial) burns First-degree burns affect only the epidermis, or outer layer of skin. The burn site is red, painful, dry, and with no blisters. Mild sunburn is an example.
These are defined as first-or second-degree burns covering 15%-25% of an adult's body or 10%-20% of a child's body, or a third-degree burn on 2%-10% BSA. Critical, or major, burns are the most serious and should be treated in a specialized burn unit of a hospital.
