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.

Introduction: Acoustic wave therapy stimulates tissue regeneration and healing processes. Therefore, it is expected that this treatment modality might have effects on scars.
Objective: To evaluate the efficacy and safety of acoustic wave therapy in the improvement of keloids.
Methods: An open, prospective, monocentric study was carried out with 20 participants with clinical diagnosis of keloid. Weekly sessions of acoustic wave therapy were performed, for eight weeks. Participants were assessed at baseline and at 1 and 12 weeks after the end of the treatment. The investigators took measurements of elasticity and performed clinical evaluations based on the Vancouver Scars Scale. At the end of the treatment the participants’ satisfaction with the treatment was evaluated.
Results: After the treatment, the percentage of participants with keloid thickness between 2mm and 5mm decreased to 47% (from 71%), increasing the percentage of participants with reduced keloid thickness in the total sample (<2mm, to 41% from 24%). Some participants also had improvement in the keloids’ vascularization and pliability. No treatment-related adverse events have been reported.
Conclusions: Acoustic wave treatment is safe and can be effective in the improvement of the keloid’s functionality and some clinical aspects.
