HIFU (High-Intensity Focused Ultrasound) is a non-invasive treatment that uses ultrasound energy to heat deep structural layers of the skin (including the SMAS layer, which surgeons pull during a face lift). This thermal energy triggers a natural healing response, causing the immediate tightening of collagen fibers and initiating the gradual production of fresh, tight collagen. It is highly effective for lifting brows, tightening jowls, and firming the neck.
Some initial tightening is felt immediately, but the main lifting and contouring results develop gradually over 2 to 3 months as new collagen is formed.
