HIFU stands for high intensity focused ultrasound. Ultrasound is a form of energy that is significantly different than light such as IPL and Lasers or Electrical (Radio-Frequency) energy. HIFU, protects the skin surface, whilst precisely penetrating at deeper depths and higher temperatures beyond the Dermis and Foundation layers, where structural weakening starts. HIFU has different transducers with different depths 1.5, 3, 4.5 and 8 mm that can penetrate into the collagen layers previously possible with surgery, therefore cells are activated and new collagen and elastin formation takes place. This causes the skin elasticity to improve and hence a lifting effect is produced within 6 months to a year. It is FDA approved treatment with a specific intent for improvement of lines and crape skin on the Face, Neck, Decolletage, Upper Arms, Upper and Lower Abdomen.
