Corner lip lift results
The short answer
One thing changes, and it is visible in a resting face: the direction the outer end of the mouth points. Rewind's Smile Lip excises slackened muscle together with redundant skin at the corner and re-fixes the corner above the mouth-corner muscle, so a pair of photographs taken under the same lighting shows the corner sitting on a different line while everything about the lip body stays as it was. Rewind publishes no standard millimetre of elevation, because the amount excised on each side is decided on the individual mouth against a reference lip proportion of 1:1.615. A comparison taken before the sutures come out at six to seven days shows swelling, and the swelling subsides gradually after that.
The surgical description, the suture window and the eating and mouth-opening limits on this page come from Rewind's own Korean page for Smile Lip. That page publishes no elevation figure, no operating time and no date on which a corner is judged settled, so this page supplies none of those either.
Two habits make a comparison worth looking at. The first is the resting face: a mouth held in a smile hides exactly the change this operation was performed for, and a photograph of a smile therefore proves the least. The second is the pair of corners together, since a mouth with a heavier drop on one side is corrected by taking different amounts from each corner, and a single-side crop leaves the balance unreadable.
Patient photographs
Rewind photographs its own patients in the clinic. For the mouth corner the clinic has not yet released a case set for publication, so the frames below are held open for it. Filling them with a stock face or with a pair borrowed from a different operation would make this page worthless for the only purpose it has, which is showing you what this surgeon's work on a corner looks like.
When the clinic releases a Smile Lip set, each pair will name every operation performed in that session, because a corner photographed after two operations is not evidence about one. Until then, ask at the consultation to see what exists in the clinic's records for a mouth like yours. What a case looks like is not what your mouth will look like: bleeding, infection, prolonged swelling, a line at the corner that stays visible, asymmetry once the swelling settles, altered sensation and a corner raised further or less far than intended are all possible, and no specific outcome can be promised.
How to read a pair
A pair of photographs is a weak instrument used carelessly and a useful one used strictly. These are the four readings that survive scrutiny, and each of them depends on the two frames matching in everything except the surgery.
The interval matters
Rewind publishes four markers for this operation, and together they explain why the photograph most patients want to take is the one worth the least. The mouth is under instruction for weeks, and a corner under instruction is a corner still moving.
A resting photograph made at the consultation, with the face at ease and both corners visible, is the only reference your own comparison will ever have. Patients who arrive without one usually end up arguing from memory, and memory of a mouth corner is unreliable in both directions.
Rewind removes the stitches at about six to seven days, and states that swelling subsides gradually from that point. Gradually is the clinic's own word. A frame taken on the day the sutures leave is documentation of the operation and no kind of result.
Mainly soft food is asked for through the first one to two weeks. The restriction protects the fixation that holds the corner in its new direction, and a mouth eating carefully is also a mouth being held differently, which shows in photographs taken in that window.
Counted from the day the stitches come out, wide opening of the mouth is avoided for one to two months. Large bites, wide yawns and dental appointments that hold the jaw open all belong in the plan made before a surgical date, and they mark the end of the period in which the corner is being actively protected.
A closure beside the mouth goes on maturing long after the restrictions end, and how any surgical line matures differs between individuals. Rewind publishes no date at which a corner is declared final, so review visits with the operating surgeon are where that judgement is made, one visit at a time.

Why in movement
A still frame answers one question about a mouth corner and cannot reach the second. The first is where the corner sits when nothing is happening. The second is what it does when you speak, eat and laugh, and that one is settled at the chair by watching, long before a camera is involved.
Dr. Choi assesses both corners at rest and then in expression, because a design that only looks correct in repose announces itself the moment the face is used. The photograph records the first reading; the consultation is where the second one is made.
Rewind runs as a single-surgeon practice. The person who decided how much tissue came from each side is the person comparing your review photographs with the baseline, which is what allows a small difference between the sides to be recognised as intentional or otherwise.
Patients who travel send photographs at the intervals agreed before they leave, taken at rest under even light so the frames stay comparable. Correspondence runs in their own language from the first message, at a clinic registered with KHIDI for foreign patients under Reg. M-2025-01-08-09288.
How cases are recorded

Fig. 05 — Where the first hours after a corner lift are spent
Rewind occupies the fourth and fifth floors of the Richro Building in Apgujeong and photographs its own patients there. Every image that reaches this website is taken with the patient's consent and shown unretouched. Consultations run Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and on Saturday from 10:00 to 16:00, by appointment. The points below are what a usable mouth-corner comparison requires.
Board-certified plastic surgeon
The mouth-corner cases held in this clinic's records were operated on by Dr. Jonghwan Choi, certified by the Korean board in plastic surgery and a member of the Korean Society for Aesthetic Plastic Surgery. International patients are treated under KHIDI registration M-2025-01-08-09288.
Published rates
A comparison is worth reading beside the figure attached to it. These are the clinic's standard published rates for a first operation, and the second line is the one that changes what a pair of photographs is showing you.
Listed figures carry the anaesthetic fee inside them and have VAT added on top. Where a plan holds two operations, the pair of photographs that follows it belongs to both, and each session is therefore named in full when a case is published. Work on a corner operated on before is quoted from the clinic's revision rates and confirmed only after examination.
Whose comparison shows most
Between the frames
The interval between a baseline and a usable second frame is spent under instructions, and the instructions are about how the mouth is used. Rewind's published notes cover the four stages below.
Naming what can go wrong belongs on a results page more than anywhere else: bleeding, infection, prolonged swelling, a line at the corner that stays visible, asymmetry between the two sides once the swelling settles, altered sensation around the corner, tightness on wide opening, and a corner raised further or less far than intended. Any of those can lead to a further procedure quoted at revision rates. Outcomes differ between individuals and no specific result can be promised. Rewind publishes no figure for how long a raised corner holds its position, so none is stated here.
Every mouth-corner case in this clinic's records belongs to one board-certified plastic surgeon, from the baseline photograph to the last review. A comparison is only as good as the consistency behind it, and consistency is what a single operator produces.

Scientific evidence
Three papers, chosen for what they say about measuring an outcome around the lip: a published description of the surgical corner-of-mouth lift, a systematic review of how lip-lift results have been reported and how thin that evidence base still is, and a single-technique series in which design and scar position are set out in detail. They study other surgeons' patients, not this clinic's, and a paper reporting a series says nothing about the mouth in your own photographs.
