Problem scars may result from inflammatory diseases particularly acne; trauma can include cuts and burns, previous surgery, and a genetic predisposition for skin to overreact to injury. Tension on the skin around the wound, foreign material in the wound, infection, or anything that delays closure of the wound may also contribute to scar formation.

The most difficult types of scars to treat are characterized by overproduction of collagen, which is the extracellular protein found in connective tissue that gives it strength and flexibility. The two types of scars that are most often considered for treatment are keloids and hypertrophic scars. Keloids are shiny, smooth benign tumors that arise in areas of damaged skin and look like irregular growths in the wound area. Hypertrophic scars, on the other hand, are thick, ropy-textured scars that are often associated with contractures.
