What type of burn is classified as having blisters?

A burn that is classified as having blisters corresponds to a second-degree burn. This type of burn affects both the outer layer of skin (epidermis) and the underlying layer (dermis). The formation of blisters is a key characteristic because it indicates that the dermis is involved, leading to fluid accumulation under the skin.

In a first-degree burn, only the epidermis is affected, resulting in redness and minor pain without blistering. Third-degree burns extend through the epidermis and dermis and into deeper tissues, often leading to a leathery appearance and can be painless due to nerve damage. Fourth-degree burns are the most severe, affecting all layers of skin and underlying tissues, including muscles and bones, and also do not produce blisters. Understanding the characteristics of these different burn types is crucial for proper assessment and treatment.
