What Is a Keloid?

According to the American Academy of Dermatology, a keloid is a smooth, hard, raised scar tissue. They differ from other types of scar tissue because they grow much more than other types of scars. Some grow larger than the original wound. Some keloid scars itch more than typical scars and may cause discomfort when they rub up against clothes. Keloids are not cancerous and don’t carry long-term health effects. They tend to form on the ears, chest, arms, and pelvic region.

The cosmetic concerns are usually the biggest concern for most people. People may feel self-conscious about a large, raised scar on their body. The person might feel more self-conscious if the scar is on a visible area of the body. Exposed keloids may change color from the sun. They may become more noticeable, which only adds to the self-consciousness. It’s important to keep keloids out of the sun for this reason.


Symptoms vary from person to person, but symptoms might include:

  • A raised area of skin that appears lumpy or ridged.
  • An area of start issue that keeps growing over time.
  • A raised itchy scar.
  • A flesh-colored, red, or pink scar.

What Causes Keloids?

A keloid forms after a wound occurs to the skin. A scrape, acne, surgery, or burn could cause a keloid. Piercing body parts and tattooing the skin could create a keloid as well. Spontaneous keloids occasionally form without injury. However, it’s extremely rare.

Silicone Gels and Sheets

The patient must wear a sheet of silicone gel on the keloid for a few months. Some dermatologists see success with this, but some disagree on the effectiveness of it. It also poses a problem because keeping the sheet on for extended periods of time isn’t easy.

Corticosteroid Injections

Steroid injections typically flatten A keloid. The keloid might become redder in color, because the steroids may help superficial blood vessels to form. Many doctors recommend laser treatment when this occurs to help reduce the redness. The skin will look and feel different than the unaffected skin around it. They are safe and come with a moderate level of pain. The course of treatment usually includes multiple injections over a period of months.

Most people stay away from surgery because more keloids could form. Some surgeons use steroids or compression to keep a keloid from forming after surgery.


This therapy uses proteins created by the body’s immune system. They inject the interferon into the keloid to reduce its size. The treatment shows promise but needs more research.
