What type of burn affects only the outermost layer of skin?

A superficial burn, also known as a first-degree burn, affects only the outermost layer of the skin, which is the epidermis. This type of burn usually results from mild sunburn or a brief exposure to hot surfaces. It is characterized by redness, minor inflammation, and discomfort, without the presence of blisters.

The healing process for superficial burns typically occurs within a few days, and they usually do not leave significant scarring. This distinction is important for understanding burn classifications, as recognizing the severity of a burn can inform proper first aid treatment and follow-up care, minimizing complications and promoting effective healing.

Other types of burns are more severe; partial-thickness burns penetrate deeper into the skin, affecting both the epidermis and part of the dermis, resulting in blistering and more intense pain. Full-thickness burns involve complete destruction of both skin layers and possibly underlying tissues, presenting a risk of infection and significant scarring. Electrical burns can vary widely in severity, depending on the voltage and duration of exposure, and may cause both external and internal injuries.
