LinearZ
Linear-shot HIFU for face and body contouring

In short
LinearZ fires HIFU energy in lines rather than points, covering an area quickly and evenly. It is used to lift the jawline and under-chin and also to firm body areas such as the abdomen and upper arms. Sessions take 20–40 minutes with no downtime, and results appear over one to three months.

Ultrasound is focused along lines in the dermis and fascia; the repair response builds collagen along each line, tightening the tissue across the whole path.

FAQ
Does body treatment hurt more than the face?
Body skin is thicker so it usually feels milder, though sensation varies by person and energy level.
How many sessions?
The face is usually one session per cycle; body areas often take two to three for a cumulative result.
