Sumario:INTRODUCTION AND OBJECTIVES: Surface depressions and skin laxity together play a role in the appearance of cellulite. Cellulite depressions can be improved through disruption of the subcutaneous fibrous structures. Some currently utilized approaches accomplish this through invasive techniques requiring local anesthesia and potential down time. Skin laxity can exacerbate the appearance of cellulite, however current invasive approaches do little to improve skin laxity. The objective of this study was to evaluate a noninvasive approach to improving both cellulite depressions and skin laxity through the use of rapid acoustic pulses (acoustic subcision). Safety, efficacy, tolerability, and participant satisfaction results were measured. METHODS: Women (n = 56) with moderate to severe cellulite were treated in a single acoustic subcision treatment session without anesthesia. Posttreatment adverse events (AEs) and tolerability were recorded. At 12‐weeks cellulite outcomes were assessed using a 6‐point simplified Cellulite Severity Scale (CSS), Global Aesthetic Improvement Scale (GAIS), and a participant satisfaction questionnaire. Additionally, laxity improvement was measured using a 4‐point Laxity Score (LS) and GAIS. RESULTS: Improvement in cellulite appearance measured at 12‐weeks showed that participants (n = 56) had a mean CSS reduction of 1.01 (a 29.5% reduction from baseline). The posttreatment photograph was correctly identified by blinded independent reviewers from randomized pairs of pre/posttreatment photographs for 96.4% of participants. Cellulite was graded as improved, much improved or very much improved using the GAIS at 90.9% of treated locations. Finally, 92.9% of participants reported positive satisfaction responses. Scoring for improvement in skin laxity appearance at 12‐weeks showed a mean LS reduction of 0.57 (a 27.9% reduction from baseline). GAIS for laxity was graded as improved, much improved or very much improved in 67.3% of treated areas. No unexpected or serious AEs were noted at treatment or follow‐up. Overall average pain score during treatment was 2.4 (0–10 pain scale) and 0.3 immediately posttreatment. CONCLUSION: A single noninvasive acoustic subcision session can safely provide meaningful improvement in the appearance of cellulite in terms of depressions, as well as skin laxity, with minimal treatment pain and no posttreatment down time. Further improvement in appearance is expected with multiple treatments over time. Additional trials to verify this are planned.
