People get scars almost everyday of their lives. It may be a scar from a scratch, injury, acne, or some viral disease that they may have had. Some only develop scratches or flattened scars but there are individuals who have tough, elevated scars called keloids or keloid scars. This type of scar is like a separated lump of skin that is colored purple or pink and irregularly shaped. Most keloids enlarge or progress. This is a type of scar that doesnâ€™t normally disappear.
