title: Novel nonablative radio-frequency rejuvenation device applied to the neck and jowls: clinical evaluation and 3-dimensional image analysis.
abstract: OBJECTIVE
  To use 3D photography to evaluate the clinical efficacy of a novel radiofrequency delivery device used to improve the appearance of rhytids and laxity of the face and neck.
  
  
  METHODS
  Forty-nine subjects received a total of two radio-frequency treatments to the face and neck one-month apart. The novel radio-frequency delivery device was used to heat the dermis between 41-43°C for five heat cycles. Primary outcome measures were clinical efficacy quantified by the Global Assessment Improvement Scale (GAIS) and a patient survey that assessed treatment satisfaction.
  
  
  RESULTS
  Assessments of 3D photographs revealed an overall improvement in 74% of study subjects. 85% of patients noted an overall improvement in the appearance of their skin. 81% of patients rated their post-treatment skin laxity as improved, 85% rated their skin smoothness as improved and 62% rated their skin brightness as improved.
  
  
  CONCLUSIONS
  Subjects in this study demonstrated an overall improvement in face and neck appearance with regard to skin tightening, wrinkles, and skin texture suggested by overall patient satisfaction (85%) and physician-rated GAIS improvement (74%). This study suggests that radiofrequency applied with a continuous thermal treatment device is a safe and efficacious way to improve the overall appearance of aging facial skin.
