What type of burn affects only the epidermis?

A first-degree burn affects only the epidermis, which is the outermost layer of skin. This type of burn is often characterized by redness, minor swelling, and pain. The most common cause of a first-degree burn is exposure to mild heat sources, such as a sunburn or brief contact with hot objects.

In contrast, second-degree burns extend into the dermis, leading to blisters and more intense pain, while third-degree burns damage both the epidermis and dermis, potentially affecting deeper tissues and resulting in a white or charred appearance. Fourth-degree burns penetrate even further, damaging muscles, tendons, and bones.

Understanding these distinctions is crucial for proper diagnosis and treatment, highlighting the significance of first-degree burns being superficial and typically more manageable than deeper burns.
