A moderate sunburn, where the skin is swollen and hot to the touch, can take a week to heal completely. A severe sunburn, characterized by intensely hot, red skin followed by blisters, can take up to two weeks to heal.

After a sunburn, the outer layer of skin is damaged, which may lead to a special type of inflammation known as neurogenic inflammation. During this process, immune cells flock to the damaged area, some releasing histamine. As a result, the skin becomes itchy and painful.

Skin can start to turn red within 3 to 4 hours but reaches peak skin reddening and inflammation between 12 to 24 hours after exposure. Increased blood flow to the area, increases heat and swelling as the lymphatic system sends fluid to that area to try to repair the damage.
