title: Electrosurgical resurfacing: a clinical, histologic, and electron microscopic evaluation.
abstract: BACKGROUND
  Radiofrequency resurfacing is a new technology for ablative facial resurfacing.
  
  
  OBJECTIVE
  To evaluate the efficacy of radiofrequency resurfacing in reduction of perioral and periorbital rhytides, and to assess it's effects on collagen remodeling by electron microscopic evaluation.
  
  
  RESULTS
  Fourteen of the fifteen subjects (93%) were 100% re-epithelialized by day 7. All 15 patients (100%) had resolution of post-treatment erythema by 3 months. Clinical investigator assessment evaluation revealed mild to moderate improvement in 100% of patients. Histologic changes were consistent with new upper papillary dermal collagen formation. Post-treatment ultrastuctural changes showed either new Type III or mature Type I collagen formation.
  
  
  CONCLUSIONS
  Radiofrequency resurfacing is an effective ablative resurfacing method for mild to moderate improvement of Fitzpatrick Type I-III rhytides. It is a low risk procedure with potentially shorter periods of post-operative re-epithelialization and erythema as compared to standard ablative laser procedures.
