Burn scars are a virtual certainty with third degree, or full thickness burns, and worse. Though superficial, second degree burns, or partial thickness burns, may also result in minimal scarring. The degree of scarring depends on the depth of the burn injury. For example, if a second degree burn was covered by clothing the effect on the patient could be minimal or could be exacerbated, depending on the material. Treatment for burn scars and injury is often quite painful and can last for weeks, months, or even years.
