Focused ultrasound lifting (HIFU)
Focusing ultrasound on a single point, this lifting treatment creates tiny spots of heat, called coagulation points, in the subcutaneous fat and in the fascia layer that supports the face (SMAS).

Depth: subcutaneous fat to fascia (SMAS) This is a model, so layer thickness is not to scale.
How it works
Examination firstIf sagging is advanced or there is very little facial fat, we first explain whether another approach would suit you better.
01What it uses
Ultrasound focused on a point
The handpiece concentrates ultrasound so that heat forms in just a small area at a set depth.
02Which layer
Subcutaneous fat to fascia (SMAS)
It reaches the fascia layer that supports the face and the subcutaneous fat above it. Depths of 3.0 mm and 4.5 mm are common, chosen to suit the area and the thickness of your skin.
03How it works
Point by point, contracting over months
It lays down rows of very small coagulation points. The coagulated tissue contracts over several months.
Concerns and how it works
If this sounds like you
- My jawline looks less defined than it used to
- My cheeks seem to have dropped
- The skin under my chin has started to sag
Sagging happens when the fat and fascia beneath the skin loosen along with the skin itself. Much as a magnifying glass gathers sunlight, focused ultrasound gathers energy at a single point at a set depth, leaving the surface as it is while forming tiny coagulation points underneath. Those points take 2–6 months to contract and rebuild, and the change differs from person to person.

Common questions
What people often ask about focused ultrasound lifting (HIFU)
How much pain should I expect?
Over areas close to the bone, you may feel a sharp, zapping or prickling pain. We reduce it with numbing cream and by adjusting the intensity.
How long will it take me to recover?
Swelling may appear and usually settles within a few days. Bruising or temporary numbness can also occur.
How many sessions will I need?
Usually one, repeated after 6–12 months if needed. Changes appear over 2–6 months.
Can I combine it with other treatments?
In the Danjeong Line program, it is paired with radiofrequency lifting on the same day or 2 weeks apart. If you are also considering filler, we decide at your examination which comes first and how far apart they should be.
