title: The dual treatment of acne vulgaris using two kinds of ELOS (electro optical synergy) system: a simultaneous split-face trial.
abstract: BACKGROUND
  RF-pulsed light with ELOS technology devices have recently been used to treat acne vulgaris in selected patients.
  
  
  OBJECTIVE
  To investigate the safety and efficacy of a combination of two kinds of device with ELOS technology for the treatment of acne.
  
  
  METHODS
  Ten patients with moderate acne were treated twice weekly for 4 weeks with the Aurora AC (Syneron Medical Ltd, Yokneam, Israel), a combination of pulsed light and RF energy. Immediately after Aurora AC treatment, all patients were treated weekly only on one facial half with the Matrix IR (Syneron Medical Ltd), a combination of fractional diode laser and RF energy. Photographic documentations were obtained at baseline, before each treatment session, and 1 and 3 months after the final treatment.
  
  
  RESULTS
  At 3 months after treatment, the mean lesion count was reduced by 38% (p<0.05) after eight treatments with the Aurora AC alone. With additional treatment with the Matrix IR, the mean lesion count was reduced by 61%.
  
  
  CONCLUSIONS
  The combination of Aurora AC and Matrix IR was superior in reducing the acne lesion count, and in extending the length of the remission period.
