Study Details:

  • 14 females with age 33-60 years, Fitzpatrick Skin Types II–IV and body mass index 24 ± 2 (range 18-30) enrolled; 10 subjects completed treatments & follow-ups
  • 3 biweekly UltraShape treatments with small 12-gram transducer (USculpt) to unilateral outer thigh subdivided into 3 areas (control thigh untreated), with mean focal treatment zones (FTZ) of 7.7 ± 2 (range 6 to 12)
  • Thigh fat thickness was measured by both caliper and ultrasound

Study Results:

  • By ultrasound, there was a significant 19.2% reduction in fat to treated thighs
  • By caliper, there was a significant 22.2% reduction in fat to treated thighs
  • Statistically significant reduction of 2.8cm in treated thigh circumference
  • No discomfort, all subjects reported 0 (scale of 0=no pain to 10) 
  • 90% patient satisfaction rate
  • Transient mild erythema only associated with the treatments
