What characterizes a second-degree burn?

A second-degree burn is characterized by the involvement of both the epidermis and part of the dermis, leading to symptoms such as red, blistered skin, and significant pain. The presence of blisters is a hallmark of this type of burn, indicating damage beneath the surface layer of the skin. The pain associated with second-degree burns is typically more intense compared to first-degree burns because the nerves in the dermis are affected, making the area very sensitive to touch and temperature changes.

This type of burn can occur from direct exposure to hot liquids, flames, or other sources of heat. It is important to manage these burns properly, as they can lead to infection, particularly if blisters are broken. Unlike first-degree burns, which only affect the outer layer of skin and may present with redness and mild pain, or third-degree burns, which destroy all layers of skin and may not be painful at all due to nervous tissue damage, second-degree burns provide a clear distinction in terms of symptoms and treatment needs.
