Study Details: 

  • 50 female subjects (mean age 44±9 years, range 25-63 years) with cellulite Stage II or III (Nurnberger–Muller scale classification) treated on 100 thighs at 4 USA clinical sites
  • Single Profound Sub-Q treatment to the upper posterolateral thighs (~15x15cm area): 67ºC target tissue temperature and 4-second pulse duration; 3-4 mm spacing between adjacent needle insertions
  • 3 dermatologists - blinded assessment of photos according to FDA guidance - dimple number and severity of undulation irregularities, using a 5-point scale (0=none to 4=severe)

Study Results: 

  • 93% success rate for independent assessment per thigh on blinded evaluation
  • Significant reduction in dimples and undulations
  • 75% of subjects reported satisfaction with treatment outcome
  • Procedural pain level was 3.74±1.96 on a 10-point scale (0=no pain) with 82% of subjects experiencing no discomfort to mild discomfort
  • Post-procedural erythema and edema were common and resolved within ~2 days on average
  • No adverse events associated with treatment
