Which type of burn destroys the entire thickness of the skin?

A third-degree burn, also known as a full-thickness burn, involves the complete destruction of the skin's three layers: the epidermis, dermis, and subcutaneous tissues. This type of burn is characterized by its appearance; the skin may look white, charred, or leathery, and it can be painless due to the destruction of sensory nerves.

In contrast, first-degree burns only affect the outermost layer of the skin (the epidermis), causing redness and minor pain without blisters. Second-degree burns penetrate deeper, affecting both the epidermis and part of the dermis, leading to blisters and more severe pain. Superficial burns are less severe and often refer to first-degree burns that cause only minor irritation.

Understanding the differences between these types of burns is critical for proper first aid and treatment, as the severity of the burn determines the appropriate medical response. Third-degree burns typically require significant medical intervention, potentially including surgery and skin grafts, highlighting their seriousness.
