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.
* Full-thickness burns may extend into the subcutaneous tissue, meaning the skin can't heal on its own. These burns, classified as third-and fourth-degree burns, are caused by prolonged exposure to chemicals, electrical current, flame, hot liquids, or tar. The skin appears dry, waxy, white, leathery, or hard.
