HIFU vs Ultherapy

Is Ultherapy the same as HIFU?

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

What Ultherapy shares with every HIFU device

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.

shared 01
Energy that converges below the surface
Ultrasound is focused to a point beneath the skin, so the surface is spared while the tissue at the focus heats. Rewind's documentation describes exactly this for its own platform.
shared 02
Heat that contracts tissue
At the focal points the tissue contracts, and collagen production is stimulated over the weeks that follow.
shared 03
No incision
Nothing is cut and nothing is implanted, which is why the whole category sits on the non-surgical side of the menu.
shared 04
A ceiling on what heat can lift
Any HIFU device works on tissue that still has elasticity. None of them stands in for surgery once tissue has descended heavily.
Differ

The differences

Where Ultherapy Prime differs from generic HIFU

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.

01See

Does Ultherapy use imaging? Yes, before each line

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.

02Depth

Ultherapy transducers are labelled by focal depth

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.

03Count

Ultherapy counts lines; HIFU offers count many ways

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.

04Proof

Checking that an Ultherapy unit is genuine

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

Why HIFU at Rewind means Ultherapy Prime

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.

01Layers

Imaging-guided HIFU suits a surgeon's reading of the face

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.

02Range

Ultherapy is one option among seven lifting devices

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.

03Record

An Ultherapy line count you can check against the quote

The lines delivered are recorded during treatment, which lets the plan you agreed be compared with the treatment you received.

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.

Cost

Pricing

Why Ultherapy costs more than some HIFU offers

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.

Ultherapy Prime, 300 linesStandard plan; coverage set at examination
₩1,300,000
Ultherapy Prime, 600 linesLarger plan for wider coverage
₩2,500,000

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.

Fit

Suitability

Who Ultherapy Prime suits, and when HIFU of any brand is the wrong tool

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.

Where Ultherapy Prime is a reasonable choice

  • Early laxity along the jaw line and under the chin, in skin that still has spring
  • Thin areas close to bone, where seeing the layers before treatment is valued
  • A patient who wants the number of lines delivered to be visible and recorded
  • Maintenance after an earlier focused-ultrasound course

Where no HIFU brand is the answer

  • Heavy descent of the lower face and neck, where surgical options are explained instead
  • A face with very little volume, where tightening may read as hollowing
  • Fullness below the chin that is mainly fat
  • Recent filler, threads or device work in the area
  • Pregnancy, breastfeeding, active infection at the site or an implanted electronic device
After

Recovery

After Ultherapy: the aftercare Rewind gives for all HIFU

Rewind gives one set of aftercare instructions for all its device lifting, so choosing Ultherapy Prime changes nothing about the days that follow.

Same day
Straight back to your day
Daily activity is possible at once. Skip sauna, strenuous exercise and alcohol for the rest of that day.
Day 1–2
Leave it alone
No rubbing or pressing the treated skin. Bruising or swelling may appear and fades within a few days.
Following weeks
Moisturise and shade
Moisturiser and sunscreen every day while collagen responds.
Months on
Results over time
The clinic records device lifting results lasting from six months to more than a year, varying with skin condition and plan.

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.

Questions

HIFU vs Ultherapy: frequently asked questions

Is Ultherapy the same as HIFU?
Ultherapy is a brand of HIFU. HIFU names the technique of focusing ultrasound beneath the skin; Ultherapy is a specific system from Merz Aesthetics, and Ultherapy Prime is the version Rewind uses. All Ultherapy is HIFU, while many HIFU devices have no connection to Ultherapy.
Why is Ultherapy more expensive than other HIFU?
Rewind prices only Ultherapy Prime and cannot quote other devices. The features you pay for on this platform are imaging before each line, transducers made for the system, a certified unit and a recorded line count. Compare cost per line on devices with the same features before comparing totals.
Does Ultherapy use imaging?
Yes. Ultherapy Prime shows an ultrasound image of the tissue layers on its screen before energy is delivered, which is why published studies describe it as microfocused ultrasound with visualization. The operator uses that image to choose the depth for each zone.
Does imaging make Ultherapy Prime a lower-risk HIFU?
Seeing the layers lets the operator confirm depth before a line is placed, which matters most over bone and thin skin. A 2014 review of this platform's safety profile is listed below. The known risks remain, including bruising, swelling, numbness and nerve irritation.
Can I compare an Ultherapy quote with a HIFU quote from home?
Yes, once both are in the same unit. Ask how many lines or shots the other quote includes, which depths it uses and whether the device images the tissue. Rewind's list gives the 300 and 600-line figures to set against it.
Is Ultherapy Prime stronger than other HIFU devices?
Rewind has no basis for ranking devices it does not operate, and the studies it cites do not compare brands head to head. What shapes the result is depth, line count, placement and whether the face suits energy lifting at all.
Which HIFU devices does Rewind offer?
One: Ultherapy Prime. The clinic's other lifting devices use different energy, namely Thermage FLX and Volnewmer for radiofrequency, Sylfirm X for microneedling radiofrequency, Max Wave for microwave and InMode, alongside a picosecond laser.
Does Ultherapy need different aftercare from other HIFU?
Rewind gives the same aftercare for all device lifting: no sauna, strenuous exercise or alcohol on the day, no rubbing or pressing the area for one to two days, and daily moisturiser and sunscreen. Bruising or swelling can appear and settles within a few days.

Scientific evidence

Published research on microfocused ultrasound with visualization

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.
