A corticosteroid, usually triamcinolone, is injected directly into the scar tissue with a fine needle. It works by reducing inflammation, holding back the excess collagen production that raised the scar in the first place, and softening and flattening what is already there.
The procedure is quick, needs no surgery and involves no downtime.
What it does
- Reduces the thickness and size of the scar
- Eases itching, pain and tenderness
- Improves the texture and appearance of the skin
What to expect
Treatment takes a few minutes in the clinic. Sessions are spaced every three to four weeks, and most people need at least three to six of them for a good result.
Where this works best
Results depend heavily on the size and age of the scar. Small scars under 1cm that are relatively new — less than two years old — do best. Larger or older scars usually need a different approach, most often intralesional cryosurgery.
Steroid injections are frequently paired with silicone sheets, a well-established frontline combination for small, fresh scars.
Side effects
Most people tolerate these injections very well. The ones to know about are:
- Thinning of the skin at the injection site
- Lightening of the skin, more noticeable on darker skin tones
- Small red veins (telangiectasia) appearing in the treated area
- Temporary tenderness or redness
