High Intensity Focused Ultrasound, also known as ‘HIFU’, ‘non-surgical face lift’, ‘lunchtime face lift’ or ‘Focus Dual’ has become one of the most sought-after lifting, firming, and tightening treatments for face and neck. HIFU uses Focused Ultrasound to target the deep structural layers of the skin with heat, which it does without damaging the skin’s surface.
