Volnewmer
The short answer
Volnewmer is a monopolar radiofrequency device, built by the Korean manufacturer CLASSYS and used at Rewind on skin that has softened with age. The clinic's Korean device record puts the mechanism plainly: radiofrequency energy arrives at the skin, is converted there into thermal energy, and coagulates tissue within it, with delivery adjusted to the condition and the type of skin in front of the doctor. The four results that same record names are firmness, fine lines, pores and skin texture.
Source: Rewind's own device documentation. Anaesthesia, appointment length and the way a count is spread across a face are not published for this device, so none of those figures appear here. They are settled at the examination and written into your plan.
Rewind holds seven lifting and skin systems, and two of them run on monopolar radiofrequency. This is the flexible half of that pair. It is published in three counts, and the smallest of those is small enough to spend on one region, so a plan can be built for a jaw line alone without buying a whole face.
The other monopolar platform here, Thermage FLX, is a different manufacturer's console with its own consumable and a single published face plan. Same class of energy, different machine, separate line on the price sheet. Neither is a version of the other, and which one is proposed follows from what the examination finds.
What it is aimed at
Rewind's device page lists four effects for this system, and the list reads as a boundary as much as a promise. Firmness, fine lines, pores and texture are all qualities of the skin itself. Tissue that has dropped and needs moving is a different problem with a different answer, and this device is not it.
Mechanism
Radiofrequency is neither light nor sound. It is an alternating current, and the tissue it passes through is what turns it into heat. Almost everything else about the treatment follows from that single fact, including why it is sold by the shot and why the result arrives in two separate halves.
Radiofrequency energy is delivered into the skin and converted there into thermal energy. A current spreads through a volume of tissue, so the heat is distributed across that volume, and the depth that ends up working depends on the settings the doctor selects.
Rewind's documentation describes the heat as coagulating tissue inside the skin. In practice, protein in the collagen network is denatured at controlled points and the fibres shorten as they change state. That shortening is the part occasionally visible within the same week.
The slower half is a healing response. Published work on radiofrequency reports new collagen and new elastin forming in treated dermis over the weeks that follow exposure. A result is therefore judged at a follow-up appointment some weeks later, under the same light as the first photographs.
Counts of 100, 300 and 600 are what Rewind publishes for this device, and a 900-shot plan appears inside the clinic's basic firming package. A larger count treats more skin at the same energy. Concentrating a small count on one spot does not make the effect stronger there, and the figure is set after the skin has been examined.

Why here
Buying a second machine in the same energy class only makes sense if the two are put to different work. At Rewind the split runs between one large published face plan and a ladder of counts that can be spent on a single region. Choosing between them is a clinical decision, made with your skin in front of the doctor.
Dr. Choi examines the face before any device is proposed. How much laxity is still recoverable, what the skin quality complaint actually is and what you have had done before all feed into which of the seven systems here is suggested, and whether any of them should be.
This kind of energy tightens tissue; it cannot lift and reposition what has already descended. When the examination finds a jowl that has dropped past what heat will hold, you are told so plainly, told what an operation would involve, and left to decide with both on the table. Patients are also turned away when there is active infection or inflamed skin in the path of the handpiece.
The 100-shot tier exists so that a limited area can be treated for what a limited area is worth. It is quoted from the same published sheet as the larger plans, with nothing folded into a bundle you cannot take apart afterwards.

The medical director writes the plan, and the appointment itself takes place across floors four and five of the Richro Building in Apgujeong, Gangnam. Device lifting is among the treatments Rewind runs Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and on Saturday from 10:00 to 16:00, and every slot is booked in advance. Makeup and an ordinary evening are possible the same day: the clinic's record for its device treatments is that patients go back to normal activity straight after the appointment.
Two things are worth having in writing when you book, because Rewind does not publish either for this device: what will be used for comfort, and how much time to set aside. Ask as well which regions your count is being spent on, and have that written into the plan before the first pulse.
Before & After
Rewind photographs its own patients under a fixed lighting setup, and each treatment gets a published set of its own. None exists for this device yet, so the frames below are empty and stay that way until one does. Brochure images from a device maker show patients Rewind never treated, photographed under a different camera.
When a set is released it will be published the way every other set on this site is: the clinic's own patients, one lighting setup, uncropped frames, and a caption naming every treatment carried out in that case. Individual results may vary, and skin treated with energy can be red, swollen or tender for a few days afterwards. An examination comes before any of it.
Pricing
Rewind publishes a rate against each count, and the desk quotes the same figure. Which count you are offered follows from the examination, and the regions it will be spent on are agreed before anything is paid for.
Listed rates, value-added tax excluded; where anaesthesia is used, its fee already sits inside the listed figure. The firming package that carries a 900-shot plan is quoted separately at consultation, because the rest of what goes into it changes with the skin. Before paying, confirm which count and which regions the figure you were given actually covers.
Suitability
Recovery
The written instructions Rewind hands out for its device treatments are short, and most of what they ask for lands inside the first forty-eight hours.
The published literature on radiofrequency tightening records burns and blistering, redness that outlasts the usual few days, changed sensation in treated skin and, uncommonly, thinning of the fat beneath it. Anything already sitting in the area matters here: fillers, threads and earlier energy sessions should all be declared, along with any implanted electronic device, 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
These papers examine radiofrequency tightening as a class of treatment, in patients treated at other centres and with the settings each study chose. None of them is a study of Rewind Plastic Surgery or of this particular device, and no individual outcome follows from any of them.
