There are three primary types of burns:
- First-degree burns: red, nonblistered skin
- Second-degree burns: Involve damage to the second layer of skin, known the dermis. Blisters and some thickening of the skin
- Third-degree burns: Involve damage to the epidermis, the dermis, and hypodermis, the third layer of skin. Widespread thickness with a white, leathery appearance.
- Fourth-degree burns: This type of burn has all of the symptoms of a third-degree burn and also extends beyond the skin into tendons and bones.
