While the degree of scar formation varies from person to person, there are some distinguishing characteristics:
- Becomes hard and non-pliable
- Bands of fibers on or below the surface
- Skin tightens or shortens. When crossing a joint, this contracture may limit range of motion, comprise function or cause deformity.
- Becomes dry and reopens to form a wound if not managed properly. This is especially true for skin grafts, which do not produce oil or sweat.
