High-intensity focused ultrasound (HIFU) is a relatively new cosmetic treatment for skin tightening that some consider a noninvasive and painless replacement for face lifts. It uses ultrasound energy to encourage the production of collagen, which results in firmer skin.

HIFU is most widely known for its use in treating tumors. The first reported use of HIFU for aesthetic use was in 2008Trusted Source.

HIFU was then approved by the Food and Drug Administration (FDA) in 2009 for brow lifts. The device was also cleared by the FDA in 2014 to improve lines and wrinkles of the upper chest and neckline (décolletage).

Several small clinical trials have found HIFU to be safe and effective for facial lifting and refining wrinkles. People were able to see results in a few months after treatment, without the risks associated with surgery.
