HIFU (High Intensity Focused Ultrasound) is a non-invasive treatment that helps lift, tighten, and improve skin quality. The technology of HIFU means that loose, crepey skin around areas such as the face and neck can be rejuvenated to reveal tighter, smoother skin. High Intensity Focused Ultrasound can also help define and contour the body through the breakdown of stubborn body fat in unwanted areas such as chin. HIFU works by emitting a precisely controlled focused beam of ultrasound. The beam passes harmlessly through the outer layer of the skin and is concentrated at the right depth to produce the correct temperatures needed to generate new collagen and elastin which will result in tighter, smoother skin. HIFU is unaffected by skin colour and it applicable to all skin types and does not affect hair growth. For best results the area to be treated should be clean shaven. The treatment is generally considered to be pain free.
