Hifu is a new type of non-surgical, non-invasive method that uses ultrasound technology and the body’s own natural healing process to tighten and tone wobbly skin on your face. HIFU treatment uses high-intensity focused ultrasound waves. Their high concentration enables the technology to get to a specific point below the surface of the skin where it reaches the SMAS layer (muscle layer). Working deep below the surface it stimulates the growth of collagen without harming the outer layer of skin. This results in long-lasting firming, and tightening of the skin, after just one treatment.
