PolarSlim uses High-Intensity Focused Ultrasounds (HIFU) technology. HIFU penetrates focused and volumetric ultrasonic energy at a precise depth (1.2m) in subcutaneous fat layers targeting fat tissue. The subcutaneous fat surrounding structures such as the epidermis, blood vessels, and nerves will not be damaged. Meanwhile, the metabolized contents (triglyceride, fatty acid) of cells will excrete outside the body automatically through blood circulation and lymphatic drainage without harm to the human body. The PolarSlim system is specifically indicated for non-invasive waist circumference reduction, body fat reduction, and slimming on thighs and lower back-fat.
