delivers powerful non-ionizing focused ultrasound energy to destroy fat cells instantly by mechanical way at controlled depth in subcutaneous fat layer, to reach long-lasting body sculpting results This energy triggers a natural response under the skin, jumpstarting the regenerative process that produces new collagen. The first investigations of HIFU for non-invasive ablation were reported by Lynn et al. in the early 1940’s. In 2015 the FDA authorized HIFU devices for the ablation of prostate tissue. HIFU can also be used to increase the flow of blood or lymph or to destroy tissue such as tumors through a number of mechanisms.
