High-intensity focused ultrasound or HIFU is a relatively new cosmetic treatment for skin tightening that some consider a noninvasive and painless replacement for facelifts. It encourages the production of collagen which results in firmer skin. Several doctor trials have found HIFU to be safe and effective for facial lifting and refining wrinkles, and Body Shaping. People were able to see results in a few months after treatment without the risk associated with surgery. HIFU has been found to be a promising treatment that could replace face lifts, especially in younger people who don’t want the risk of surgery. HIFU (ultrasound energy) targets the layers of skin just below the surface and causes the tissue to heat up rapidly. Once the cells in the target area reach a certain temperature, they experience cellular damage. While this may seem counterintuitive the damage actually stimulates the cells to produce more collagen. It will give the perfect structure to the skin.
