A burn is characterized by severe skin damage that causes the loss of skin cells. Burns are divided into three types based on their severity: first degree, second degree and third degree burns. The degree of burn is determined based on the amount of damage to the skin. In this way, first-degree burns are the most minor and third-degree burns are the most severe.
Damage includes:
First degree burns: redness, skin without blisters
Second degree burns: Blisters and some thickening of the skin
Third degree burns: extensive thickness and skin with a white, leathery appearance
Of course, it goes without saying that there are also fourth degree burns. This type of burn includes all the symptoms of a third degree burn. But it also spreads outside the skin and towards the tendons and bones.
