What Causes Skin Redness?

First Degree Burn

A first-degree burn is a superficial burn injury to the top layer of an individual's skin. Most first degree burns are a mild skin injury that does not necessitate medical treatment but can be painful and uncomfortable. The most common causes of first degree burns include sunburns, hot liquid scalds, and exposure to electricity. The most common symptom seen in individuals who have first degree burns is skin redness in the affected area. The skin redness that develops from a first-degree burn is the result of the individual's immune system responding to the cellular injury or damage that has occurred. Along with redness of the skin, an individual who has a first-degree burn may experience tenderness, pain, and swelling at the burn site. Most first-degree burns that are not extensive and do not cover a large area of skin will heal within a few days. A second-degree burn can be distinguished from a first-degree burn by the formation of painful blisters at the burn site.
