Clinical Evaluation of the MIRA Technique in Cellulite Treatment: A Retrospective Case–Control Study

Background: Cellulite is a highly prevalent aesthetic concern characterized by structural remodeling of subcutaneous adipose tissue and fibrous septa, resulting in visible skin irregularities. Despite the availability of many injectable treatments with documented efficacy, most standard approaches adopt uniform protocols that overlook interindividual anatomical variability, potentially limiting treatment precision and clinical outcomes. This retrospective case–control study evaluated the Modulated Insertion of Regenerative Activation (MIRA), a technique that individualizes needle length and injection angle according to ultrasound findings, modulating insertion parameters to stimulate regen-erative responses within dermal and subcutaneous layers. Methods: Clinical and ul-trasonographic data from 120 women with stage 3 cellulite were analyzed. Stage 3a pa-tients received carbon dioxide therapy (CDT), whereas stage 3b patients underwent in-jectable solution therapy (IST). Within each treatment, patients were allocated to MIRA or control groups. Results: Compared with controls, MIRA showed greater reductions in adipose tissue thickness (CDT: −1.6 mm; IST: −1.5 mm; padj = 0.002), nodules, pain, edema, and fibrosis, with improved fascia regularity. Patient satisfaction was higher in MIRA (CDT: 8.1 ± 1.6; IST: 8.5 ± 1.4; padj = 0.002), and over 76% reported improved skin quality. Conclusion: Ultrasound-guided modulation of needle parameters with MIRA may en-hance structural and esthetic outcomes compared with standard approaches.
