Which type of burn breaks the skin surface and forms blisters?

A second-degree burn is characterized by more severe damage than a first-degree burn, which only affects the outer layer of skin, known as the epidermis. In a second-degree burn, both the epidermis and part of the underlying layer, the dermis, are affected. This damage leads to the formation of blisters, as the body reacts to the injury by collecting fluid in the spaces between the epidermis and dermis.

These blisters serve as a protective barrier, helping to prevent infection and aid in the healing process. They also indicate the severity of the injury, as second-degree burns can be painful and cause swelling, redness, and streaks in the surrounding area. Healing time can vary depending on the depth of the burn and the care provided. In contrast, first-degree burns don’t form blisters and involve only the epidermis, while both third-degree and fourth-degree burns penetrate deeper into the skin layers and tissues, leading to more severe damage but not blister formation in the same way.
