Occasionally, the burned area blisters, and hairs in the burn can easily be pulled from their roots. The burned area has no feeling when touched. Generally, third-degree burns aren't painful, because the nerve endings in the skin have been destroyed. Prognosis Healing depends on the depth and location of the burn. A new layer of epidermis can grow quickly from the base of a superficial burn with little or no scarring.
Deep burns injure the dermis.
A new layer of epidermis grows slowly from the edges of the burned area and from any remnants of the epidermis in the burned area. Consequently, healing is very slow and scarring is considerable. The burned area also tends to contract, distorting the skin and interfering with its functioning. Mild burns of the esophagus, stomach, and lungs generally heal without problems. More severe burns, however, can lead to scarring and narrowing, called contractures.
