High-Intensity Focussed Ultrasound (HIFU)
HIFU is the shorthand acronym for High-Intensity Focussed Ultrasound, a type of treatment that uses ultrasound waves. As its name says, HIFU uses ultrasound waves at high intensity rather than lower intensity and focuses the waves to a single point. The focussed ultrasound waves don’t hit the surface of the skin, as a laser would, but a predetermined spot up to 4.5mm below the skin’s surface. Scroll down for all the FAQs about HIFU.
