HIFU lifting
The short answer
HIFU stands for high-intensity focused ultrasound. Sound energy is focused to a point below the surface, the way light is focused through a lens: the skin it passes through is left intact, while the tissue at the focal point is heated enough to contract and to trigger new collagen. It is a category of treatment, not a single machine, and the machines inside it differ from each other more than the marketing suggests.
Source: Rewind's own device documentation, Korean original. The clinic's ultrasound platform is described there as delivering energy to the deep fascial layer without damaging the surface, for wrinkle improvement, firmness and a cleaner facial line.
Patients arrive asking for HIFU the way they might ask for antibiotics: a category name standing in for a decision that has not been made yet. Which device, at which depth, over which area, and whether ultrasound is even the right energy for the face in question are four separate questions.
This page is the map. Rewind's ultrasound treatment has a page of its own, and so does each of the other energy devices held here; what follows is how the category works and how to tell one offer from another.
The lifting menu
Four kinds of energy are held in the same clinic, and they are not interchangeable. Knowing which family a treatment belongs to tells you more about what it can do than any brand name does.
Rewind holds seven lifting devices in total: the ultrasound platform, two radiofrequency systems, microneedling radiofrequency, microwave, InMode and a picosecond laser. Which one is named in your plan is decided after the examination.
How to read an offer
HIFU is sold in units, and the units are where most of the confusion lives. Four things decide what a quote is actually worth, and all four can be asked about in plain language at the desk.
Ultrasound plans are sold in lines, microwave plans in joules, radiofrequency in shots. A price with no count attached is not a price. Rewind publishes the count beside every plan, and the figure on your quote should match the figure on the plan you were shown.
Focused ultrasound systems carry cartridges that concentrate energy at different levels, from superficial dermis down to the fascial plane. Which levels your face receives, and over which zones, is an operator decision taken against your anatomy.
Imaging-guided ultrasound puts the tissue layers on a screen before a line is delivered, so depth is chosen against what is there. Over bone, over implants and on thin skin, that difference stops being academic.
A large number of lines placed in the wrong face buys nothing. The diagnosis in front of the machine decides the result, and it is the part of the offer no price list can show you.

Why here
A clinic that owns one lifting machine has one recommendation available to it. Rewind is a single-surgeon practice built around lifting, with the surgical option in the same building, so the category question can be answered before the device question is asked.
Dr. Choi examines the face and says which tissue is causing the complaint. Some faces are a skin problem, some are a fat problem, some have descended past the point where any energy holds them. The first answer is a category, and only then a machine.
Ultrasound, radiofrequency, microneedling radiofrequency, microwave, InMode and a picosecond laser are all in the room. When the honest recommendation is the cheaper plan, nothing in the inventory argues against saying so.
The person who set your plan is the person who reads the result at follow-up. International patients are supported in their own language from the first enquiry through to that appointment.
In the treatment room

The clinic occupies the fourth and fifth floors of the Richro Building in Apgujeong. A visit opens with the medical director examining the face and naming the device and the count; the session follows in the device room on the same floors. Rewind works by appointment only and consults Monday, Tuesday, Wednesday and Friday between 10:00 and 19:00 and on Saturday between 10:00 and 16:00, which is what most patients who are in Seoul for work plan around.
Ask to see the device you are paying for and the manufacturer documentation that belongs to it. Rewind displays the certificate issued for its ultrasound platform in the clinic and holds manufacturer certificates for its device line-up; anywhere in the world, a clinic that will not show you that paperwork has told you something. Anaesthesia and session length are not published for these treatments, so ask for both when you book.
Before & After
Rewind photographs its own patients under identical lighting and releases pairs treatment by treatment. None have been released for energy lifting, so the frames below hold their place until they are.
Any pair published here will be a Rewind patient, photographed uncropped under matched lighting, with the device and the count named beside it. Individual results may vary; the degree of change from an energy treatment depends on skin condition, age and how much laxity was there to begin with. Redness or brief swelling can follow a session.
Pricing
Rewind publishes one rate per plan, and each plan carries the count it is sold in. The microwave plans below are quoted in joules; the ultrasound plan is quoted in lines and is set out in full on its own page.
List prices, VAT excluded; anaesthetic fees are included in the listed price where anaesthesia is used. Body plans on the microwave device are listed separately at the same joule counts, and plans that combine two devices are quoted once the doctor has examined the area. Nothing on this list carries a traveller's mark-up.
Suitability
The category has a real ceiling. Saying where it sits is more useful to a patient flying in for a week than any list of benefits.
Recovery
Rewind's aftercare for device lifting is deliberately short. Bruising or swelling can appear and settles within a few days, and ordinary activity carries on from the moment you leave.
Focused ultrasound carries documented risks: temporary redness, swelling, bruising, tenderness, numbness and altered sensation, with nerve irritation and uneven or unwanted tissue loss reported less often in the published complication literature. Tell the doctor about every injection, thread and device session the treated area has had before yours.
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
These six papers cover the category: a systematic review, a clinical overview, the early work on how focused ultrasound injures tissue precisely, a prospective neck and lower-face study, a safety study in Asian skin and a complication series. They describe devices, settings and patients that are not Rewind's, and no individual outcome can be read from them.
