Rejuran
The short answer
Rejuran is a polynucleotide skin booster. Long-chain DNA fragments, purified from salmon, are injected into the dermis as a grid of small deposits. Nothing is being filled or lifted: the material is read by the skin as a repair signal, and whatever change follows is built by your own tissue over the weeks after the session.
Rewind lists this treatment inside its skin-booster menu alongside its other injectable lines. The volume and the line — Healer for facial skin, Eye for the thin skin below the eye — are set with the doctor at consultation.
The category word matters when you compare quotes. A skin booster is a product class, and polynucleotide is one chemistry inside that class; hyaluronic-acid water injections, exosome preparations and polylactic-acid stimulators all sit in the same menu and answer different questions. Rewind separates them at diagnosis instead of selling the menu as one thing.
The practice is a plastic surgery clinic, so an injectable is never the only tool in the room. When the complaint you describe is skin quality, a booster is a reasonable place to start. When the complaint is a fold or a jaw line that has dropped, the surgeon says so at the consultation and shows you what a booster would and would not move.
Placement
Published work on long-chain polynucleotide injection describes facial skin rejuvenation as the main application, with the periocular area treated as a separate problem because the skin there is thin and moves constantly. The zones below are the ones that come up most often in consultation; your own map is drawn on your face, not copied from this page.
Mechanism
The material has no volumising job and no lifting job. It is a biological signal placed where fibroblasts live, and the pharmacology literature on polydeoxyribonucleotide — the closely related preparation that carries most of the published mechanism work — is what this class of product is argued from.
The starting material is salmon-derived DNA, cut into long chains and purified so that what remains in the vial is the nucleotide chain itself. That is why the product is described in patient language as a salmon DNA injection, and why a known sensitivity to fish-derived material is worth mentioning at consultation.
Delivery is by many shallow injections across the treated zone instead of one bolus. Small raised points can be visible for a short time afterwards, which is a feature of the technique and not a sign that something has gone wrong.
Pharmacology reviews of polydeoxyribonucleotide describe activity at adenosine A2A receptor pathways and effects on fibroblast behaviour and tissue repair. Those papers study the material, not this clinic and not your face; they explain why the class exists, and they stop short of promising any individual outcome.
What is injected is metabolised. Whatever improvement in skin quality follows is maintained by repeating the treatment, and it fades if you stop. Rewind's own Korean guidance for boosters gives a duration band rather than a fixed figure, because product and skin condition both move it.

Who plans it
Boosters are the easiest treatment in any clinic to sell and the easiest to over-prescribe, because they are quick and because almost nobody is refused. Rewind is a single-surgeon practice built around lifting, which changes the incentive: the same doctor who would have offered you an operation is the one deciding that an injection is enough.
Dryness, fine lines and texture belong to the skin. Heaviness at the jaw or a deepened fold belongs to structure. Dr. Choi separates the two at the consultation and tells you plainly when a booster will leave the thing that bothers you exactly where it is.
Seven lifting and skin devices sit in the same clinic as the injectable menu. When more than one treatment is appropriate, the order and the spacing are decided in advance, so that aftercare instructions for one do not collide with the next appointment.
Results are looked at by the person who planned them, and the plan for the next session is adjusted from what the skin actually did. International patients are supported in their own language from the first message through to that review.
On the day

You are seen by the medical director, the zone and the volume are agreed, and the injection is carried out in the clinic on the fourth and fifth floors of the Richro Building. The clinic runs by appointment only, Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and on Saturday from 10:00 to 16:00, which is what most working patients and most visiting patients plan around.
One thing the clinic does not publish is a fixed comfort protocol for this treatment. Rewind's Korean source pages record a numbing cream for some of its booster products and record nothing for others, so instead of guessing on your behalf, the clinic asks you to raise comfort at booking and settles it with the doctor before the first point is placed.
Case photography
The clinic's photographic archive is a surgical one: standardised lighting, fixed angles, patients who consented to publication for operations. No booster series has been released for this page, so the frames stay empty and labelled instead of being filled with a stock face or a surgical case borrowed from another treatment. Ask at consultation — cases can be shown in the room under the clinic's consent rules even when they are not published on a web page.
Any photograph published here will be Rewind's own patient, photographed under the same lighting and the same angle on both dates, uncropped, with written consent. Individual results may vary and cannot be promised in advance. Injection into the skin can leave bruising, small raised points, redness or swelling; a consultation with the doctor is required before any decision.
Pricing
Rewind publishes one rate per vial size. What changes between two patients is how many vials the plan uses and how often it is repeated, and both of those are decided in front of you at the consultation. Package pricing across several sessions is quoted in the room after the doctor has looked at the skin.
Rates above are list rates and VAT is added separately. Where a numbing preparation forms part of the session, its cost already sits inside the listed rate. Rewind does not run a separate foreign-patient rate, and the figure quoted in the consultation room is the figure on this list.
Suitability
Recovery
Rewind's aftercare for boosters is short enough to read once and strict enough to be worth following. Mild redness or stinging can appear and settles within a few days; ordinary daily life resumes as soon as you leave.
Injection carries risk. Bruising, swelling, redness, stinging and small firm points at the injection sites are the common ones; infection and vascular events are rare but real, and any increasing pain, blanching or dusky discolouration is a reason to contact the clinic the same day. Tell the doctor about every treatment you have had in the same area, including fillers and energy devices.
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
The papers listed here examine polynucleotide and polydeoxyribonucleotide preparations as materials, including one study of cell proliferation outside the skin. They were not conducted at Rewind Plastic Surgery, they do not describe this clinic's patients, and no outcome reported in them should be read as a prediction for an individual.
