When the highly strong ultrasonic energy is collected to focus, strong heat (65 ~ 100 ℃) is generated and it is called high intensity focused ultrasound(Hifu). When about a hundred thousand times stronger ultrasonic wave is focused in one point than the intensity of the ultrasound used to diagnose, the heat is generated in the focused area, which is similar that collecting the solar light to focus the heat using a convex lens.
Typical applications of Hifu is a skin lifting and tumor removing surgery.Hifu lifting is a relatively new, innovative procedure that uses ultrasound technology to penetrate deeply into the skin, affecting a connective tissue layer called the SMAS. It utilizes highly focused ultrasound energy waves to tighten the SMAS layer of the skin at both the 3mm and 4mm depth. HIFU helps the body produce more collagen and the deep focused ultrasound produces tightening of the deep supportive connective tissue of the face.
Hifu therapy is considered a natural skin tightening alternative because it works with your body’s natural healing process. The HIFU machine infuses “seeds” of thermal coagulated heat into multiple layers of the skin causing micro-wounds. As your skin heals, new collagen is formed which then tightens the skin.
