Keloids Overview
Learn About Keloids
A keloid is a growth of extra scar tissue. It occurs where the skin has healed after an injury.
Keloid scar; Scar - keloid
Keloids can form after skin injuries from:
- Acne
- Burns
- Chickenpox
- Ear or body piercing
- Minor scratches
- Cuts from surgery or trauma
- Vaccination sites
Keloids are most common in people younger than 30. Black people, Asians, and Hispanics are more prone to developing keloids. Keloids often run in families. Sometimes, a person may not recall what injury caused a keloid to form.
A keloid may be:
- Flesh-colored, red, or pink
- Located over the site of a wound or injury
- Lumpy or ridged
- Tender and itchy
- Irritated from friction such as rubbing on clothing
A keloid will tan darker than the skin around it if exposed to the sun during the first year after it forms. The darker color may not go away.
Keloids often do not need treatment. If the keloid bothers you, discuss your concern with a skin specialist (dermatologist). Your dermatologist may recommend these treatments to reduce the size of the keloid:
- Corticosteroid injections
- Freezing (cryotherapy)
- Laser treatments
- Radiation
- Surgical removal
- Silicone gel or patches
These treatments, especially surgery, sometimes cause the keloid scar to become larger.
