The development of HIFU (High Intensity Focused Ultrasound) of FINESSE enables targeting the facial SMAS, the fan-shaped structure that covers the face and connects the facial muscles with the dermis. In facial procedures, the HIFU relies only on heat to achieve its effects on tissue.
The goal is to elevate the local temperature to at least 65°C, the temperature at which collagen contraction begins to occur. HIFU causes discrete thermal coagulation points while sparing adjacent tissues. In addition to local coagulation, the application of heat causes collagen fibers become denatured and contract.
This new collagen formation occurs within the areas of thermal tissue coagulation results in the tightening and lifting of sagging facial and neck skin and improvements in the appearance of wrinkles.
