Which layer of the skin is affected by a second degree burn?

A second-degree burn is characterized by damage that extends beyond the outermost layer of skin, known as the epidermis, and affects the underlying layer called the dermis. This type of burn typically involves both of these layers, leading to symptoms such as blistering, swelling, and significant pain. The presence of blisters is a key indicator that the dermis has been impacted, as these blisters form in response to the injury and contain fluid that helps protect the underlying tissues.

Understanding the structure of the skin is crucial in recognizing the extent of the damage caused by burns. While first-degree burns only affect the epidermis and heal without scarring, second-degree burns compromise both the epidermis and the dermis, potentially leading to scarring or changes in skin texture if not properly treated. Additionally, deeper burns, such as third-degree burns, would include damage that reaches the subcutaneous fat or even deeper layers, but since the question specifically asks about second-degree burns, the involvement of just the epidermis and dermis is accurate.
