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 regenerative responses within dermal and subcutaneous layers. Methods: Clinical and ultrasonographic data from 120 women with stage 3 cellulite were analyzed over a 30-day follow-up period. Stage 3A patients received carbon dioxide therapy (CDT), whereas stage 3B patients underwent injectable 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. Conclusions: These explorative findings suggest that ultrasound-guided modulation of needle parameters with MIRA may enhance structural and esthetic outcomes compared with standard approaches. Prospective randomized trials are needed to confirm these results.
