Keloid is an overgrowth of the scar tissue that develops around a wound, usually after the wound has healed. It is an abnormal type of wound healing, which results in a large, soft growth where the skin has been damaged. It is particularly common in people with dark skin.
Keloid typically starts to develop about three months after the original skin damage although it can take up to a year. The first thing you will probably notice is that rubbery scar tissue starts growing beyond the borders of the original damage. It may become tender, itchy, and painful or produce a burning sensation. Sometimes keloid develops without any apparent skin injury, although most people can identify a cause.
