High-intensity focused ultrasound (HIFU) is a relatively new cosmetic treatment for skin tightening that some consider a non-invasive and painless replacement for facelifts. It uses ultrasound energy to encourage the production of collagen, which results in firmer skin.
How does high intensity focused ultrasound work?
HIFU uses an ultrasound transducer, similar to the ones used for diagnostic imaging, but with much higher energy. The transducer focuses sound waves to generate heat at a single point within the body and destroy the target tissue. The tissue can get as hot as 65 °C in just 20 seconds.
Does HIFU tighten skin?
HIFU for skin tightening is known as an optimal treatment for the face as well as other areas of the body where excess fat exists, such as the abdomen, buttocks, neckline and thighs. It increases collagen production to tighten the skin and help improve the appearance of fine lines and wrinkles.
