The increase in collagen results in tighter, firmer skin with fewer wrinkles. While this may seem counterintuitive, the damage actually stimulates the cells to produce more collagen - a protein that provides structure to the skin. Once the cells in the targeted area reach a certain temperature, they experience cellular damage. The ultrasound energy causes the tissue to heat up rapidly. HIFU uses focused ultrasound energy to target the layers of skin just below the surface. HIFU won’t work as well for people with more severe cases of sagging skin. So far, HIFU has been found to be a promising treatment that could replace face lifts, especially in younger people who don’t want the risks and recovery time associated with surgery. More evidence will be needed to find out who is best suited for this type of procedure. While the procedure is also used for overall facial rejuvenation, lifting, tightening, and body contouring, these are considered “off-label” uses for HIFU, meaning the FDA has yet to approve HIFU for these purposes. People were able to see results in a few months after treatment, without the risks associated with surgery. Several small clinical trials have found HIFU to be safe and effective for facial lifting and refining wrinkles. The device was also cleared by the FDA in 2014 to improve lines and wrinkles of the upper chest and neckline (décolletage). HIFU was then approved by the Food and Drug Administration (FDA) in 2009 for brow lifts. ![]() The first reported use of HIFU for aesthetic use was in 2008. HIFU is most widely known for its use in treating tumors.
