Twenty-four-month persistence of hyaluronic acid filler for an atrophic scar.

A 24-month follow up of a previously reported case of successful hyaluronic acid filler use in steroid atrophy is presented. The patient had persistence of the volume and appearance of her scar with sustained satisfaction 24 months after hyaluronic acid treatment, without the need for repeat injection. This case suggests expansion of the use of hyaluronic acid fillers to include scar atrophy, as persistence of a desired cosmetic appearance for 2 years is demonstrated.
