What is a scar?

Stuart A. Linder, MD
Plastic Surgery
Typically, a scar is the final product from the body's healing process after surgery or wound formation. Scars occur after both primary closure, aka sutures placed, or secondary closure where no sutures are placed and where the wound edges come together by themselves. Scaring can include multiple types. Scarring can include keloids in which the collagen formation outgrows the border or boundaries of the scar. Hypertrophic scarring in which the scar can normally be revised surgically with increased collagen formation, however, does not outgrow the borders.  Hyperpigmentation with increase in melanin in the scarring or hypopigmentation with the reduction of the pigment within the scar. Widespread scars are associated with increased tension on the wound edges leading to spreading of the incision.

Scars are the body’s process of healing from an injury.  When the skin is damaged it repairs itself by the process of forming a scar.  All wounds, whether surgical or as the result of an injury, heal with scarring.
