What characterizes a 2nd degree burn?

A second-degree burn is characterized by deep partial thickness damage, which involves both the epidermis and part of the dermis. This type of burn results in the formation of blisters and causes significant pain and swelling. The presence of blisters is a key distinguishing feature, indicating that the damage extends beyond just the outer layer of skin (the epidermis) into the deeper layers where fluid collects. The healing process for second-degree burns can vary in duration and may lead to scarring, depending on the extent of the damage.

In contrast, full thickness burns are characteristic of third-degree burns, where the damage is more severe and extends through all layers of the skin, potentially affecting underlying tissues. A burn that only affects the epidermis represents a first-degree burn, which typically presents with redness and minor pain but lacks the blister formation seen in second-degree burns. Lastly, burns that result in limited skin redness and minor pain indicate superficial injuries rather than the deeper tissue involvement seen in second-degree burns.
