Which burn type involves damage to the dermis?

A second-degree burn is characterized by damage that extends beyond the epidermis (the outer layer of skin) into the dermis, which is the layer beneath the epidermis. This type of burn typically causes symptoms such as redness, swelling, pain, and the formation of blisters. The involvement of the dermis can lead to varying degrees of skin loss and may also result in scarring as the tissue heals.

In contrast, first-degree burns only affect the epidermis, causing minor discomfort without blistering or severe skin damage. Third-degree burns extend through both the epidermis and dermis and can also damage underlying tissues, leading to a white, charred appearance and significant loss of sensation. Fourth-degree burns go beyond the skin, affecting deeper tissues such as muscles, tendons, and bones, and are often life-threatening.

By identifying that a second-degree burn damages the dermis, the correct answer emphasizes the depth of injury and its corresponding symptoms, which are essential aspects of understanding burn classification and management.
