THE OPERATING PRINCIPLE
The technique consists of delivering a high-frequency ultrasound beam and microfocused energy deep within the skin, with a high degree of precision:
- Hifu face: application to 4.5 , 3 and 1.5 mm
- Hifu body: application to 8 and 13 mm
This focused beam acts thermally, causing immediate contraction of the collagen fibres and triggering neocollagenesis in the months following the treatment.
