After an injury or surgery, the body responds by forming scar tissue. Scar formation is a normal part of the wound healing process, but not all scars are the same. Some scars form in only the superficial epidermal layers, whereas others encompass deeper subdermal layers, involving nerves and tendons. The process of scar formation is the result of myofibroblast cells forming new collagen fibers to repair a wound.
