HIFU vs Ultherapy
The short answer
Ultherapy is one brand of HIFU. HIFU, high-intensity focused ultrasound, is the name of the technique; Ultherapy is a system made by Merz Aesthetics that applies it, and Ultherapy Prime is the version installed at Rewind Plastic Surgery. Every Ultherapy treatment is therefore a HIFU treatment. The reverse does not hold, because many machines use focused ultrasound and they vary in imaging, transducers and the way plans are counted.
Device details come from Rewind's equipment documentation and the manufacturer's own interface. Rewind holds a single focused-ultrasound platform, so this page compares device features and makes no comparison between providers.
Patients often meet the two words in separate advertisements and assume they are rivals. They sit at different levels. One describes how energy reaches the tissue; the other names a particular system with its own imaging, its own transducers and its own record of what was delivered.
At Rewind, focused ultrasound is offered only on Ultherapy Prime. What follows sets out what that device shares with the rest of the category and what it adds, so that any HIFU offer you are weighing can be read against it. The full device profile is on the Ultherapy Prime page.
Common ground
Set the brand names aside and four features belong to focused ultrasound as a technique. On these points the two words describe the same thing.
The differences
Four features separate one focused-ultrasound system from another. Ultherapy Prime can be described on each from its own documentation and interface; for any other device, the same four questions are worth putting to whoever offers it.
Ultherapy Prime shows an ultrasound image of the tissue layers on its screen, so the operator can see where bone, muscle and fat sit before energy is delivered. The published papers on this platform call it microfocused ultrasound with visualization.
The platform uses interchangeable transducers, each set to a single focal depth. One plan can combine depths across different zones, and which depths your face receives is decided at examination.
Each activation is logged on screen as a line. HIFU plans on other systems may be written in shots, lines or treated areas, so matching the units is the first step of any fair comparison.
Rewind displays the genuine-device plaque issued for its Ultherapy Prime, so the name on your quote can be checked against the machine in the room.

Why here
A clinic's device list decides what it can recommend. Rewind holds one focused-ultrasound platform beside radiofrequency, microwave and thread options, and its medical director is a plastic surgeon.
Dr. Jonghwan Choi plans in terms of anatomical layers. A system that puts those layers on screen fits the way a face is assessed across the consultation desk.
Where ultrasound is the wrong energy for a concern, radiofrequency, microwave or threads are in the same building, so no face has to be fitted to Ultherapy for want of anything else.
The lines delivered are recorded during treatment, which lets the plan you agreed be compared with the treatment you received.
In the treatment room

Rewind occupies the fourth and fifth floors of the Richro Building in Apgujeong, Gangnam. The appointment opens with Dr. Choi examining the face, confirming that focused ultrasound is the right family for the concern and setting the plan size; treatment follows in a device room on the same floors. The clinic works by appointment and consults Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and Saturday from 10:00 to 16:00.
Anaesthesia and session length are not published for this treatment, so both are discussed when you book.
Ultherapy® Prime · Genuine-device clinic
The plaque issued for Rewind's Ultherapy Prime unit is displayed in the clinic. Rewind also keeps manufacturer certificates for its other lifting devices.
Pricing
Rewind lists Ultherapy Prime at two plan sizes. The clinic has no lower-cost HIFU device to set beside it, so it cannot quote one. What it can set out is what the figure pays for: a system that images the tissue, transducers supplied for that system, a certified unit and a plan written by a plastic surgeon. When a cheaper HIFU figure reaches you, compare it on those four points and on cost per line before comparing totals.
List prices, VAT excluded; the anaesthetic fee is part of the listed figure where anaesthesia is used. A plan combining Ultherapy Prime with another lifting device is quoted after examination.
Suitability
Brand makes no difference to the limits of the technique. These lists apply to Ultherapy Prime and also mark where focused ultrasound in general runs out.
Recovery
Rewind gives one set of aftercare instructions for all its device lifting, so choosing Ultherapy Prime changes nothing about the days that follow.
Imaging does not remove the known risks of focused ultrasound: temporary redness, swelling, bruising and tenderness, and less often numbness, altered sensation or nerve irritation. Tell the doctor about every earlier treatment in the area before the plan is written.
At Rewind, one board-certified plastic surgeon carries every case — from the first consultation to the final follow-up. Because a face is a story, and a story deserves a single author.

Scientific evidence
Two of these papers concern the imaging-guided form of focused ultrasound, one of them its safety record; the third is a clinical overview of ultrasound skin tightening. They were not conducted at Rewind and do not predict what any one patient will see.
