3D-HIFU is the latest technology used to target specific focused areas of fat in the fastest possible treatment time. This technology works by delivering focused energy at a depth deep enough to destroy fat cells. The high frequency of the ultrasound wave results in heating under the skin, effectively destroying the fat cells and tightening the skin in the area treated. The damaged cells are flushed away by a natural removal process through the lymphatic system that continues for up to 3 months.
