Keloids occur from such skin injuries as surgical incisions, traumatic wounds, vaccination sites, burns, chickenpox, acne, or even minor scratches. They are fairly common in young women and African Americans. Keloidosis is a term used when multiple or repeated keloids are produced.

Most keloids will flatten and become less noticeable over a period of several years. They may become irritated from rubbing on clothing or other forms of friction. Extensive keloids may become binding, limiting mobility. They may cause cosmetic changes and affect the appearance.

Exposure to the sun during the first year of the keloid's formation will cause the keloid to tan darker than surrounding skin. This dark coloration may become permanent.
