Keloids can be considered to be "scars that don't know when to stop." A keloid, sometimes referred to as a keloid scar, is a tough heaped-up scar that rises quite abruptly above the rest of the skin. It usually has a smooth top and a pink or purple color. Keloids are irregularly shaped and tend to enlarge progressively. Unlike scars, keloids do not subside over time.
Buy silastic gel and apply it to the keloid. These come in gel sheets, which you can cut to fit the size of the keloid and hold them in place with a tape that adheres to skin. This must be used regularly every day for several weeks or months and works to get rid of the keloids by flattening the raised skin.
