Hyaluronic acid, placed where volume has gone

Dermal filler at Rewind
The short answer
A dermal filler is a hyaluronic acid gel injected into a hollow so that the surface above it sits where it used to. Rewind uses it to restore volume that has gone and to give a flat-reading face its contour back. The change is visible on the day it is placed, and the clinic publishes a duration of six to twelve months depending on the product used and on the individual.
Source: Rewind's Korean treatment page for hyaluronic acid filler. Domestic and imported products both appear on the clinic's own price list, and the choice belongs to the area being treated.
Gel adds. It does not tighten skin, it does not shorten a muscle, and it cannot lift tissue that has already descended. Those are three different problems with three different answers, and separating them is what the first appointment is for.
Where the gel goes
Four requests make up most of the filler bookings that arrive from overseas. Side cheek volume is treated the same way and is quoted from the same per-syringe list; body areas are a separate treatment with their own page and their own volumes.
Product and plane
Hyaluronic acid is one molecule with many formulations. Published comparisons measure the physical properties of injectable gels side by side, and those properties decide which syringe suits which area: a soft, spreadable gel under thin eyelid skin, a firmer one where the job is projection over bone.
Rewind's list carries a domestic gel and two imported ones, each sold by the cubic centimetre. The selection is made by what the area needs in firmness and spread. A patient request for a particular brand is discussed, but the anatomy decides.
The same volume looks entirely different placed deep against bone and placed just under the skin. Injection guides for the upper face map those planes area by area, and a surgeon who works in the same layers during lifting operations is reading familiar ground.
Facial arteries run in known positions, and the serious filler complications are vascular. The literature maps these danger zones for injectors, and separate work has measured how needles and cannulas differ in the force needed to penetrate an arterial wall and in observed occlusion rates.
An enzyme, hyaluronidase, breaks down hyaluronic acid gel. Rewind lists dissolving as its own per-area item, which matters both for a result you dislike and for the emergency protocol every injector should be equipped for.

Why here
Filler is the easiest treatment in Gangnam to buy and one of the harder ones to undo. The value of a surgical practice shows in the two moments that matter: when someone should be talked out of a syringe, and when something goes wrong.
Dr. Choi dissects the mid-face and the nose in surgery, which is the same map a filler needle travels blind. The vessels he avoids in the treatment room are vessels he has seen.
A cheek that has emptied and a cheek that has slid downward produce a similar shadow, and filling the second one adds weight to a face that already has too much. When the examination shows descent, he explains which lifting options exist and what they would cost you in recovery.
Dissolving is a listed treatment here, and a plan that can be reversed is a plan you can change your mind about. Follow-up is with the doctor who injected you, working from your own chart.
In the treatment room

Fig. 05 · Reception, where international appointments are confirmed
Every visit is booked in advance, and the clinic sees patients Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and on Saturday from 10:00 to 16:00. You are examined by the medical director, the areas and the number of syringes are agreed, the injection is given on the fourth or fifth floor of the Richro Building, and you walk out able to carry on with your day.
The clinic publishes neither an anaesthetic protocol nor a treatment length for this injection, and neither figure is invented here. Ask about both when you book, and bring the details of any filler you already have in the area, including where and when it was placed.
Before & After
Three case sets are published here, one for each of the areas Rewind has released photographs for. Each pair is one patient, photographed under the same lighting and conditions, and no other procedure was performed in any of these three cases. What you are looking at is gel alone.
BEFOREAFTER
BEFOREAFTER
BEFOREAFTERAll photographs are taken by Rewind Plastic Surgery of its own patients, under identical lighting and conditions, and are shown uncropped. Individual results may vary, and the same volume of gel behaves differently in different tissue. Swelling, bruising, lumps and, rarely, vascular complications can follow any filler injection. A consultation with the doctor is required before any decision.
Pricing
Filler is priced per syringe here, so a quote is arithmetic you can do yourself once the doctor has said how many cubic centimetres the area needs. Dissolving is priced separately, per area, and is quoted the same way whether the gel was placed here or somewhere else.
List prices, VAT excluded, with any anaesthetic fee already included in the listed figure. Two syringes in one appointment are charged as two; there is no volume discount hidden in the quote. Areas and products not shown above are quoted at consultation.
Suitability
Nose filler or rhinoplasty? Gel can raise a bridge and it can disguise a small step, and it does so in a single appointment with no operation. What it cannot do is narrow a wide bony base, correct a deviation or refine a tip that needs cartilage work; and the nasal area carries the highest vascular risk in filler practice, with visual loss documented in the ophthalmology literature. Where the examination shows a structural problem, Dr. Choi says so, explains what the surgical route would involve, and declines the syringe.
Aftercare
Rewind's written guidance for this injection covers the first day in detail, and the reason is simple: fresh gel can still be moved by pressure, and a treated area that is left alone settles faster.
Report severe or increasing pain, blanching or mottling of the skin, or any change in vision immediately, at any hour: these are the signs of vascular compromise, the complication that makes filler a medical treatment and not a cosmetic one. Lumps, asymmetry, prolonged swelling, a bluish tint in thin skin and delayed nodules are also documented, and every one of them is a reason to come back early.
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 describe hyaluronic acid fillers as a treatment class: how gels differ in their physical properties, where the facial vessels run, what the reported complications are and how the enzyme that reverses the gel is used. None of them was conducted at Rewind Plastic Surgery, and none of them predicts what a given volume will do in a given face.
