Introduction: Low level laser therapy has been considered a non-invasive treatment alternative to body remodeling and fat tissue reduction.
Objective: To evaluate the efficacy of low level laser therapy in reducing body circumference measures and subcutaneous adipose tissue of the abdomen and hips areas.
Methods: An open, prospective, monocentric study was performed including 25 women with localized fat on the hips and abdomen. Nine sessions of low level laser therapy were performed over 3 weeks. The participants were assessed at baseline and at 1, 4 and 12 weeks after treatment. Assessment of weight and body circumferences, lipid profile tests and MRI were performed.
Results: The abdominal circumference measurements showed a significant reduction up to 12 weeks after the treatment. Participants showed a more marked reduction in the hips region one week after the last session. Also one week after the completion of the treatment, 80% of the participants considered that the treatment improved their body contour. There was absence of reports of adverse events related to the treatment.
Conclusion: Low level laser therapy is safe and effective in reducing the circumference measurements, particularly in the abdominal region.

Enlarged or ptotic submandibular glands (SmG) can negatively impact the mandibular angle and facial contour. Although botulinum toxin type A (BoNT-A) is well established as a treatment for parotid hypertrophy, its use for the treatment of SmG enlargement remains underexplored. A literature search was conducted in the PubMed, Cochrane, and LILACS databases, covering studies from November 1977 to November 2024. Seven studies met inclusion criteria, encompassing animal models, cadaveric studies, clinical trials, and case reports. Studies reporting SmG size found volumetric reduction following BoNT-A administration. Current evidence suggests BoNT-A injections into the SmG effectively reduce gland volume and may enhance facial contour.
