High-Intensity Focused Ultrasound (HIFU) energy stimulates the skins deep support structures including the SMAS, which is the area often targeted by cosmetic surgeons. The device causes micro-injuries at three different skin layer depths to encourage the growth and formation of new collagen

Collagen is a substance in the skin that gives it structure and elasticity.

HIFU can:

• Tighten the skin on the neck.
• Reduce the appearance of jowls.
• Lift drooping eyelids or eyebrows.
• Smooth wrinkles on the face.
• Smooth and tighten chest skin
  
  

The type of ultrasound that this procedure uses is different than the ultrasound that doctors use for medical imaging. HIFU uses high energy waves to target specific areas of the body.

The most common areas to use HIFU are the face and neck. You can expect to notice your skin lifting and tightening with immediate effect, with ongoing results in the ensuing weeks. 
Optimum results will be seen at 6-12 weeks, leaving you feeling smoother, brighter and firmer, and will continue to improve for up to six months following your treatment. Results last for between 12 to 18 months.
