A scar is skin that forms over a wound as the skin heals. There are five main types of abnormal scars:
- Keloid—Thick scars that grow out from the skin. They spread beyond the site of the wound.
- Contracture—Often the result of a burn injury. The scar appears as a tightening of the skin. This type may also affect muscles and nerves below the skin.
- Hypertrophic—Thick, raised scars. They look like keloid scars but do not spread beyond the site of the wound.
- Atrophic—Thinned out, cigarette paper-like scars.
- Acne—May look like deep pits or be angular and wavelike.
