Keloids are overgrown areas of scar tissue that form at the site of a previous injury such as an incision, wound, vaccination, pimples, ear or body piercings. A keloid appears on the skin as an irregularly-shaped, flesh colored or red scar that is raised above the rest of the skin and continues to grow into areas that were not affected by the initial injury.
Treatment of keloids can vary depending on the personal preference and desired outcome of the patient, but may include injections or surgery to reduce the appearance or completely remove the keloid and restore the appearance of the skin. These procedures are considered safe, but may leave a scar in the treated area. No re-piercing may be done after keloid excision.
