In short. A keloid is scar tissue that grows beyond the edge of the original wound, sometimes far beyond, and rarely settles without treatment. It recurs after simple removal often enough that surgery alone is considered a mistake, so excision is always paired with immediate adjuvant therapy. The realistic goal is control, not permanent removal.
Key points
- A keloid grows past the original wound edge and rarely regresses untreated.
- Genetics dominates; family history and darker skin types raise the risk.
- Corticosteroid injections repeated over months are first-line for flattening and symptoms.
- Excision is always paired with immediate injection, pressure or radiation.
- Recurrence after any method is possible; the goal is control, not cure.
Who develops a keloid?
Genetics dominates. Keloids run in families and are more frequent in darker skin types, though anyone can develop them. Earlobes after piercing, the chest, shoulders and jawline are common sites, and a keloid can itch, ache and restrict movement. Any skin injury can trigger one: piercing, surgery, burns, acne, even scratches. That is why prevention counselling comes first for keloid-prone patients considering any procedure.
How is a keloid diagnosed?
The hallmark is growth past the wound border, often with claw-like extensions. The scar is usually firm and may be tender. Atypical or rapidly changing lesions are biopsied to exclude other diagnoses. The history of recurrence after previous treatment matters more than any single measurement, and it shapes the plan.
Why do single treatments fail?
The tendency that built a keloid is not confined to the lump you can see. It reaches past the original wound edge, so removing the visible tissue does not remove the process that produced it, and the scar returns. Recurrence after simple removal is common enough that surgery alone is considered a mistake. Excision is paired with immediate postoperative injection, pressure or radiation therapy under specialist protocols, never performed alone.
The working combinations
| Approach | What it contributes | Typical course | Limit |
|---|---|---|---|
| Corticosteroid injections | Flattens the scar and relieves itch and pain | Repeated over months | First-line; needs a series |
| Surgery plus adjuvant therapy | Removes bulk; the adjuvant guards against recurrence | Day surgery; adjuvant started on schedule | Never surgery alone; delay undermines the result |
| Laser and light | Reduces redness and bulk | Between or alongside injections | Improves injection response; not a substitute |
| Cryotherapy and topical agents | Selected roles | Smaller or earlobe keloids | Limited role in large keloids |
| Silicone and pressure | Supports long-term control | Ongoing | Supportive, not definitive |
The plan for an established keloid is a combination, and the combination is what controls recurrence. Silicone and pressure also carry the result between clinic visits.
What treatment can and cannot achieve
Keloids can usually be flattened, softened and made more comfortable, and their colour can be improved. Complete permanent removal is uncommon, and recurrence after any method is a real possibility that honest counselling quantifies rather than hides. The realistic goal is control: a flat, quiet scar and a plan for acting early if it stirs again.
Anaesthesia and the course of care
Injections are clinic visits with topical numbing. Recurrence-prevention protocols may involve several sessions over a year. Surgical excision for large keloids is day surgery, with the adjuvant plan started on schedule. Delays undermine the result.
Prevention, and when to seek assessment
Elective piercing and non-essential surgery deserve special caution. Wounds in high-risk sites are closed with tension-minimising technique, and any new scar in a keloid-prone person is followed early, because small keloids are far easier to control than established ones.
Arrange assessment if:
- A scar is enlarging beyond its wound edge, or a removed keloid is returning.
- Pain, itch or joint limitation is significant.
- A keloid ulcerates, bleeds or changes appearance suddenly. Biopsy is considered.

Frequently asked questions
Why is cutting a keloid out on its own a mistake?
Because keloids recur after simple removal often enough that surgery alone is considered a mistake. Excision is always paired with immediate postoperative injection, pressure or radiation therapy under specialist protocols, never performed alone.
Can a keloid be permanently removed?
Complete permanent removal is uncommon. Keloids can usually be flattened, softened and made more comfortable, and their colour improved, but recurrence after any method is a real possibility. The realistic goal is control rather than cure.
Who is at risk of developing a keloid?
Genetics dominates. Keloids run in families and are more frequent in darker skin types, though anyone can develop them. Any skin injury can trigger one, including piercing, surgery, burns, acne and even scratches, so prevention counselling comes first.
Risks & Limitations
- Reconstruction is usually staged — more than one operation is normal, and the plan may change as healing progresses.
- Donor-site scarring and discomfort, including after rib cartilage harvest.
- Partial or complete failure of a flap or graft, which may require further surgery.
- Scars are permanent. They mature and fade but never disappear.
- Asymmetry and the inherent limits of matching a normal side.
- Altered sensation, numbness or weakness in the operated area.
- Contracture, which may need release procedures later.
- Final assessment is made at 6–12 months, and longer in growing children.
When to Seek Care
- A flap or graft that turns dark, cold, black or stops bleeding when pricked.
- Fever above 38 °C, or spreading redness, warmth or discharge around a wound.
- New or worsening pain, swelling or fluid leakage from the operative site.
- Bleeding that does not stop with gentle pressure.
- Any change in a reconstructed area that concerns you, however minor.
