Jaw slimming, priced
The short answer
Rewind lists the chewing-muscle injection as two unit plans, one of fifty units and one of one hundred, and quotes both from a published rate list. That figure covers the muscle itself. Anything else the examination turns up — the gland beneath the jaw, the upper chewing muscle at the temple, an expression area on the same visit — carries its own listed rate and is added as its own line. Value-added tax sits outside every figure on the list.
Source: the clinic's Korean rate list and its own treatment page for this injection, which publishes an effect lasting three to six months.
Because the muscle recovers, this is a recurring line in a budget. Most first-time visitors price a single appointment and are surprised a year later; pricing two or three sessions across twelve months is the arithmetic that matches what the clinic actually publishes about duration. The full area menu sits on the botulinum toxin page.
What a quotation is made of
The Korean list is written item by item, and the English quotation follows it line for line. Four of those lines account for almost every lower-face enquiry that arrives from abroad. None of them absorbs another: a quotation that covers two of them shows two figures.
From examination to figure
Nothing about the number is negotiated. What is decided at the appointment is which listed lines your face needs, and that decision comes before anyone mentions money.
You are asked to bite down while the surgeon holds the angle of the jaw. A muscle that swells under the fingers is the thing this injection treats. Width that stays hard and unchanged through a clench is bone, and width that stays soft is fat or gland. Two of those three answers lead somewhere other than this rate list.
Rewind states that the dose is set to the individual structure of each patient. The list therefore carries two plans and no sliding scale between them. Published technique for aesthetic contouring of the lower jaw with type A toxin treats the muscle body as the target, and the plan follows the size of that muscle.
When the gland or the temple muscle contributes, those lines appear underneath the muscle plan at the figures the clinic publishes for them. No bundle rate is invented at the desk, and no line is quietly folded into another.
With a published duration of three to six months, one appointment describes a fraction of the cost of holding a narrower lower face. Ask for the per-session figure and then multiply it by how often your own muscle is likely to need re-treating; that second number is what you are really deciding about.

Why here
A figure quoted before anyone has felt the muscle is a figure for a treatment nobody has yet shown you need. The examination is what turns a rate list into a quotation.
Dr. Choi spends part of every working week on contour surgery, so the difference between a muscular jaw, a bony one and a fatty one is a distinction he draws daily. When the width is skeletal he says so, and the quotation for this injection never gets written.
Moving straight to the larger plan sells more product on day one and buys a hollow, over-relaxed lower face in month two. Where the examination supports the lighter plan, that is what is quoted, and the result is reviewed before anything is added.
The units placed, the points used and your own account of how long the effect held are kept on file. A returning patient is therefore priced from evidence about their own muscle, and international patients are helped through that conversation in their own language.
What the fee covers

Every visit is booked in advance. The clinic sees patients on Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and on Saturday from 10:00 to 16:00, and is closed on Sunday and Thursday. The fee you were quoted covers the examination by the medical director, the agreed units, and the injection itself in the treatment room on the fourth or fifth floor.
The clinic publishes neither an anaesthesia protocol nor a treatment length for this injection, so neither is stated here or built into the figure you are given. Raise both when you book, and mention any injection placed in the same area elsewhere, since that can change what is appropriate to charge you for.
Published rates
These are the standard published figures behind a lower-face quotation in Apgujeong. Read them as components: your own total is the muscle plan the examination selected, plus any additional line it justified.
Figures are list rates with value-added tax charged on top. Where an anaesthetic is used, its fee already sits inside the figure shown. Two lines treated on one visit are added together at these rates. Items absent from this page are quoted at the consultation once the examination has decided whether they apply.
This month at Rewind — offers published by the clinic, updated monthly.
Worth paying for, or not
Refusal has a price attached to it as well. A patient who arrives asking for the hundred-unit plan and leaves with an explanation of why their width is skeletal has paid for a consultation and saved a year of repeat injections that would have changed nothing. Where the complaint turns out to be lost volume, the accurate answer points to dermal filler instead, and it is priced from its own list.
What you bought, over time
The change is slow in a way that surprises people who have had expression areas treated before. A forehead reads differently within a week; a chewing muscle has to shrink from disuse, and that takes the better part of two months.
Documented risks of injecting this muscle include bruising, swelling and tenderness at the point of entry, headache, a temporary change in the shape of a smile if the dose spreads, chewing fatigue with hard food, and asymmetry between the two sides. A hollow appearance under the cheekbone can follow repeated large doses in a thin face. Report anything unexpected early, while the plan can still be adjusted.
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
None of these papers concerns fees. They are listed because each one describes something the figures above depend on: the contouring technique itself, how the potency of a type A preparation is established in controlled trials, and the adverse events reported when the method is used in aesthetic practice. They report other investigators' series and predict nothing about an individual jaw.
