title: Subdermal minimal surgery with hyaluronic acid as an effective treatment for neck wrinkles.
abstract: BACKGROUND
  Neck wrinkles are common, troublesome aesthetic deformities for which a limited number of treatments exist. Although previous study has demonstrated the safety and efficacy of subdermal minimal surgery technology in treatment of acne scarring, this technology has never been applied to treatment of wrinkles.
  
  
  OBJECTIVE
  To evaluate the efficacy and safety of subdermal minimal surgery technology in the treatment of horizontal neck wrinkles.
  
  
  METHODS
  All 12 enrolled participants were Koreans (Fitzpatrick skin types II-IV) with horizontal neck wrinkles. Participants underwent up to four sessions of treatment with subdermal minimal surgery technology at 4-week intervals. Wrinkle assessments were conducted at baseline and 2 months after the final treatment session. Participants and physicians evaluated improvement using pre- and post-treatment photographs.
  
  
  RESULTS
  All participants completed the study. Improvement of wrinkling by at least 50% was observed at 6 months (2 months after the final treatment session) in more than half of the participants, as determined according to physician and participant evaluation.
  
  
  CONCLUSIONS
  Findings from this preliminary study demonstrate that use of subdermal minimal surgery technology results in an effective decrease of the appearance of neck wrinkles.
