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

The type of burn that affects only the top layer of skin is known as a superficial burn. This category of burn, also referred to as a first-degree burn, typically involves the epidermis, which is the outermost layer of skin. Superficial burns are characterized by redness, minor swelling, and pain, akin to what one might experience from mild sunburn.

This type of burn heals relatively quickly, often within a few days, without leaving scars. In contrast, options like partial-thickness burns extend deeper, involving both the epidermis and part of the dermis, while full-thickness burns penetrate through all skin layers and can damage underlying tissues. A deep burn contextually refers to severe injuries that may damage muscles and tendons beyond the skin layers, leading to significant complications.
