title: Treatment of acne scars with hyaluronic acid: an improved approach.
abstract: 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
  
  
  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
  
  
  CONCLUSIONS
  Microinjection of low viscosity HA offers a valuable technique for the treatment of discrete depressed acne scars
