title: [Acne scars and striae distensae: Effective treatment with medical skin needling].
abstract: BACKGROUND
  Medical skin needling as a nonablative procedure appears to be a good alternative to conventional surgical treatment options for the treatment of acne scars and striae.
  
  
  OBJECTIVE
  The effect of medical skin needling particularly with regard to the treatment of acne scars and striae as an alternative to ablative therapy options is explained.
  
  
  METHODS
  A summary of recent publications on medical skin needling in terms of skin regeneration in vivo and improving skin quality of patients in vivo in striae is provided.
  
  
  RESULTS
  Medical needling shows a positive effect on the healing process of the skin, proven in clinical studies providing positive results in the treatment of striae and acne scars. Thus, PCI is a good alternative to conventional surgical procedures.
  
  
  CONCLUSIONS
  The therapeutic strategies are numerous, and even if no single modality results in complete remission of scars, medical skin needling is a safe, easy-to-perform treatment option with very promising results.
