The transducer irradiates 65-75° of HIFU energy, then creates thermal coagulation on the target layers of skin tissue with no damage to the skin surface. Superficial Musculo-Aponeurotic System (SMAS) that is the same layer of tissue that plastic surgeons pull tight in a lower face lift. As the treatment’s thermal energy safely heats this tissue, it contracts resulting in immediately tightening of that skin.
