Background: Acne scarring is a prevalent and challenging cosmetic issue, which is often addressed by multiple modalities. A low-viscosity non-animal stabilized hyaluronic acid (NASHA) dermal filler, injected in microdoses into the mid-to-superficial dermis, may provide a useful new approach to improving the appearance of depressed acne scars. Materials and Methods: Twelve consecutive patients with moderate to severe acne scarring, who had completed a series of fractional laser resurfacing, underwent microinjections of 20 mg/mL hyaluronic acid (HA) gel into discrete depressed acne scars on the face. Results: Immediate visual improvement was observed in all lesions. The procedure was well tolerated. Adverse events were limited to transient pinpoint bleeding at the injection site. Conclusion: Microinjection of low viscosity HA offers a valuable technique for the treatment of discrete depressed acne scars.
