Skin is the body’s largest organ. A burn is an injury to this organ. Burn treatments vary based on the severity of the injury.
A first-degree burn affects only the uppermost or outer layer of the skin. This burn causes mild redness, swelling and pain.
A second degree, or partial thickness, burn affects both the upper layer of the skin and the skin underneath it. Some specific symptoms for this burn include redness, swelling, pain and blistering.
A third degree, or full thickness, burn is the most severe and destroys the deep layers of the skin. This can lead to numb skin and white or blackened skin.
