First-degree burn

A first-degree burn is a minor red burn of the top layer of skin, such as a mild sunburn. The burned skin may hurt and be slightly swollen, and it may make a person feel slightly feverish.

First-degree burns usually heal with home treatment in about 3 to 5 days. They do not usually cause blisters or scars.
