Keloid treatment: why cutting one out usually fails
A keloid is a scar that did not know when to stop. Excision alone recurs in most cases, and often comes back larger.

Excision alone recurs in the large majority of keloids and frequently returns larger, so it is only offered inside a combined protocol with intralesional therapy, pressure and silicone. The realistic aim is control and flattening with symptoms resolved, over a minimum of twelve months of follow-up, not disappearance.
What a keloid is
A normal scar stops. A keloid does not: collagen production continues past the boundary of the original wound, producing a raised, firm, often itchy or tender lesion that extends beyond where the injury was. It is a property of how you heal rather than of what happened to you, which is why it recurs and why you are likely to form them again elsewhere.
Why excision on its own is the wrong operation
Cutting out a keloid creates a fresh wound in exactly the tissue that over-responds to wounding. Without adjuvant treatment, recurrence rates are high and the recurrence is often larger than the original. That is not a surgical failure; it is the predictable behaviour of the condition.
What a combined protocol looks like
- •Intralesional therapy. Steroid, or steroid with an antimitotic, injected under pressure directly into the scar. Four to six cycles at four to six week intervals.
- •Pressure. Clips for earlobes, compression garments elsewhere. Compliance here is the difference between control and recurrence.
- •Silicone. Gel or sheeting, twelve hours minimum daily, for six to twelve months.
- •Excision, only if indicated, and only with the adjuvant schedule already booked before the surgery.
What improves, and in what order
Itch and tenderness usually settle first, often before anything looks different. Flattening becomes visible from around week three of the injection cycle. Colour is last. If symptoms return, they return before height does — which is why reporting a returning itch matters more than it sounds.
The twelve-month watch
Most recurrences declare themselves within the first year. Attending the reviews where you feel fine is the point of the protocol, not an optional extra, and continuing silicone and pressure for the full prescribed duration is what holds the result.
If you form keloids, avoid elective skin trauma — new piercings and tattoos in particular. Ask before, not after. The honest answer is usually no.
One side effect worth knowing about
Intralesional steroid can thin and lighten the skin around the injection site, and occasionally makes small vessels visible. It is dose-related and it is managed by adjusting the protocol rather than abandoning it. Report it as soon as you notice it.
