Thus, the focused sound waves promote lifting in the superficial and deep layers of the skin, caused by the production of collagen fibers, and the sound waves can also reach the muscles of the region. The action of the MFU with the concentration of energy at the focal point promotes a thermal response, without damage to blood vessels, peripheral sensory nerves, and adjacent tissues.

MFU can present frequency variation of 1 to 10 MHz and controlled depth of the focal point, through specific вЂњcartridgesвЂќ containing appropriate transducers for the controlled emission of focused sound waves. It is a non-ablative and non-invasive response, promoting an increase in the production of collagen and elastin. The physical mechanism involved consists of the transmission of mechanical waves, which are converted into concentrated thermal energy at the points of application, inducing a controlled and localized inflammatory response. In recent years, the effectiveness and safety of this device have been well documented. Micro focused ultrasound (MFU) is a technology used to treat sagging skin, especially on the different regions of the face and neck.

Additionally, the volunteers expressed high level of satisfaction (93%) with the treatment Conclusion: The MFU promoted the production of collagen, reorganization of the dermis and, clinically, a reduction of sagging and wrinkles, with increased facial symmetry. In the analysis of adverse reactions, only transient hyperemia was observed with the presence of pain during application. In the immunohistochemical analysis, we observed the presence of the macrophage marker IHQ: CD68, indicating phagocytosis of adipose tissue and the presence of fibrosis. The histological analysis showed an increase in the amount of fibroblasts (p = 0.02), blood vessels (p = 0.0062) and inflammatory cells (p = 0.0036), in addition to the production of type 1 collagen. Results: We observed a visible clinical improvement on the images by photography, and an improvement of facial symmetry in the measurements of the paralateronasal projection (p = 0.007), left lateral mandibular (p = 0.01), and right lateral mandibular (p = 0.008). The volunteers answered a questionnaire to assess adverse reactions and satisfaction.

Samples of the treated skin were taken after the surgical procedures and submitted to histological and immunohistochemical analyses. Two volunteers were submitted to blepharoplasty surgery, and one to rhytidoplasty surgery 45 days after the application of the MFU.

Clinical photographic analysis and facial symmetry analysis using Dolphin Imaging software were performed, and validated questionnaires. The parameters used were: 10 MHz cartridge with depth of 1.5 mm, 7 MHz with depth of 3 mm, and 4 MHz with focal depth of 4.5 mm doses ranged from 0.1 to 2.0 J, according to the sensitivity of the volunteers treated, and the application time was of approximately 90 minutes. A single application of the MFU was performed across the facial region. The sample consisted of 30 volunteers, who were evaluated before treatment, 45 and 90 days after its beginning. Methodology: This is an experimental study. Objective: evaluate the effects of micro focused ultrasound on facial rejuvenation. Introduction: Micro focused ultrasound (MFU) is formed by mechanical waves emitted in a focused manner, concentrating thermal energy on a certain point or region, promoting a clinical improvement in wrinkles.
