Wound healing is a process of restoration of the tissues after the internal inflammation and blood clotting. Sometimes the tissues are restored completely as it was before the wound. In this case, there is no scar. But, there are times when the injury is very deep and the tissues cannot be restored as before. In this case, specialised tissues like the connective tissue fill and repair the damaged tissue but a scar is formed.
