What is HIFU ?
The human skin will age with the passage of time. In addition to the aging of the epidermis, muscle sagging caused by fascia and ligament relaxation is a deeper cause: the problem of relaxation of the superficial myofascial system of SMAS. It is a layer of connective tissue film that covers the deep subdermal tissue and connects the fatty subcutaneous tissue with the superficial muscles. It is closely connected with the skin (epidermis, dermis) and subcutaneous tissue (fat) to form a facial contour, which supports the integrity of the skin, muscles and bones. With the increase of age, the amount of collagen in the SMAS layer gradually decreases, causing facial muscles to relax and sag, deepening the wrinkles, and even the eyebrows bulging, and the signs of aging begin to appear.
What is the SMAS layer?
At present, most plastic surgery performed by plastic surgeons, the operating layer is the SMAS layer (superficial muscle fascia system, referred to as fascia layer). The SMAS (fascia) layer is located about 4.5mm deep inside the skin and subcutaneous fat. And muscles.
HIFU MACHINE principle
HIFU is a non-invasive (non-invasive) ultrasound technique that acts directly on the SMAS layer. HIFU's high-intensity focused ultrasound technology is an ultrasound surgical technology that emerged in the 1940s. It uses ultrasound as its energy source, uses its penetrability and focusability, and focuses the ultrasound energy emitted by the ultrasound on the SMAS layer of the human body. A high-intensity area—focal area—is formed in the SMAS, which can penetrate 3.0mm-4.5mm subcutaneously to make the temperature of the SMAS tissue reach above 65 ° C within 0.5-1 seconds (the strongest temperature of all non-invasive skin tightening instruments) As a result, collagen in the SMAS tissue is reorganized without damaging normal tissues outside the focal zone, thereby achieving the effect of fascia lifting.
