title: Recollagenation of acne scars.
abstract: BACKGROUND
  Depressed acne scars remain a difficult problem to correct with present methods.
  
  
  OBJECTIVE
  A new process to restore the dermal thickness destroyed by acne inflammation, called recollagenation, was developed.
  
  
  METHODS
  After an intradermal pocket was created at each depressed site, an implant of freeze-dried, irradiated, human cadaver fascia lata was inserted through a needle hole to elevate the depressed epidermis. Selected sites were retreated to establish the desired dermal topography.
  
  
  RESULTS
  Initially, local inflammation created an elevated phlegmon at the treatment site, which then progressively leveled over the subsequent 4-10 weeks. Ultimately, a predictable improvement in skin contour occurred in the majority of depressions.
  
  
  CONCLUSIONS
  Recollagenation is an effective method to repair acne lesions.
