Filler didn't work for my acne scars - what to try instead

Filler may not be effective for dipped acne scars, or the effect may not last. Common reasons are that the scars are tethered, or that the filler migrates after placement. Filler cannot release the fibrous bands that hold a scar down, so the scar continues to pull the surface inwards.

Why the effect fades

The visible correction can reduce over time as filler is broken down or moves elsewhere, even though the material itself may still be present for years. Filler placed into the surface of the skin often tends to migrate to the edge of the scar rather than staying in the centre, where it is most helpful.

How subcision can help

For tethered rolling scars, subcision divides the fibrous bands pulling the scar down so that the scar can lift. Often this is enough on its own, but where there is more significant volume loss, filler can be placed in the same session to restore the volume within the space that has been created.

Should I try permanent filler?

I use only hyaluronic acid fillers. If a complication occurs, hyaluronic acid can be dissolved with hyaluronidase, and overcorrection, migration and nodules can usually be improved. With permanent and semi-permanent materials none of this is possible, and the remaining options are surgical.
