title: Treatment of acne scars with liquid silicone injections: 30-year perspective.
abstract: BACKGROUND
  This article addresses the use of liquid injectable silicone as both an immediate and long-lasting treatment for broad-based, depressed acne scars. The only filler substance that maintains precision and permanence in improving and/or correcting these types of acne scar defects is medical-grade liquid silicone.
  
  
  OBJECTIVE
  We describe five patients with a history of acne scarring who showed improvements from injections of liquid silicone at the initial treatment session and lasting over a 10-, 15-, and 30-year follow-up period.
  
  
  METHODS
  Monthly liquid silicone injections using a technique known as the microdroplet, multiple-injection approach.
  
  
  RESULTS
  This article documents the safety, effectiveness, and precision of silicone in addition to highlighting the fact that its permanence is what distinguishes it from other filler materials.
  
  
  CONCLUSIONS
  As a precise and permanent filling substance used for soft tissue augmentation, liquid injectable silicone can improve and/or eliminate depressed, broad-based acne scars through a technique known as the microdroplet, multiple-injection
