Use of a microwave device for the treatment of cellulite and localized fat adiposity: a 1‐year follow‐up study

BACKGROUND: The body contour market has grown steadily over the last years, due to the persistent demand for non‐invasive treatments for localized fat adiposities, cellulite, and skin laxity. MATERIALS AND METHODS: The purpose of this observational study was to evaluate the efficacy and safety of a new device delivering microwaves (MWs) energy for unwanted fat and cellulite reduction after a full cycle of treatments and 1 year later. A total of 45 patients with localized adiposity and/or cellulite in different body areas (inner thigh, upper arm, abdomen, culotte de cheval, buttocks), received four treatment sessions, 4 weeks apart. Photographic records and global aesthetic improvement scale (GAIS) score were performed. RESULTS: For the treatment of cellulite the average GAIS score passed from 3.65 ± 0.49 at 1‐month follow‐up (1MFU) to 2.7 ± 0.66 at 1‐year follow‐up (1YFU). For the treatment of localized adiposity, the average GAIS score passed from 3.52 ± 0.51 at 1MFU to 2.82 ± 0.88 at 1YFU. No particular red area was detected either during or after the treatment. There was no mention of assessment of pain or side effects. CONCLUSIONS: The study findings showed that MWs allow for the treatment of cellulite and localized fat adiposity in a safe and effective way, with results lasting over time up to 1 year after the end of the treatment.
