title: Nonablative wrinkle treatment of the face and neck using a combined diode laser and radiofrequency technology.
abstract: BACKGROUND
  Nonablative laser systems that integrate optical and conducted radiofrequency (RF) energies are a novel technology for the treatment of wrinkles.
  
  
  OBJECTIVE
  This two-center study investigated the safety and effectiveness of combination diode laser (900 nm) and RF for the treatment of wrinkles and skin texture.
  
  
  METHODS
  Patients with grade II to IV wrinkling on the face, according to the Glogau classification system, were treated with a combination diode laser and RF using a fluence of 30 to 50 J/cm2 and RF energy of 80 to 100 J/cm3. Patients received up to three treatment sessions at 2- to 3-week time intervals. Wrinkle assessments using the Glogau scale were conducted at baseline and at 3 months following the last treatment. In addition, patients and physicians graded the level of improvement using pre- and post-treatment photographs.
  
  
  RESULTS
  Twenty-three subjects completed all three treatment sessions. Of these participants, more than 50% had a greater than 50% improvement in the appearance of wrinkles. All subjects reported a noticeable improvement in skin smoothness and texture.
  
  
  CONCLUSIONS
  This preliminary study demonstrates that the combination of diode laser and RF energies decreases the appearance of wrinkles and improves skin texture.
