Keloid scars

Also called Keloids

A keloid scar is a raised scar that grows bigger than the original wound. It can develop after a cut, burn, piercing, acne, chickenpox or surgery, often on the chest, shoulders, earlobes or upper back. Keloids are more common in people with darker skin and can run in families.

What it is

They are harmless, but can be itchy, tender or affect confidence.

Treatments include steroid injections, silicone gels or sheets, freezing, and pressure dressings. Surgery alone often leads to the keloid coming back.

Common signs

  • A raised, shiny scar that extends beyond the wound
  • Pink, red, purple or darker than the surrounding skin
  • Itching or tenderness
  • Slow growth over months

How it is usually diagnosed

  • Examination of the scar

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Photos of the scar over time
  • Notes on treatments tried

Questions to ask your doctor

  • Which treatment is best for my scar?
  • How can I prevent keloids after future surgery or piercings?
  • Is it likely to come back?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A scar that suddenly grows quickly, bleeds or changes in appearance: get it checked soon
