Juvelook
The short answer
Juvelook is an injectable collagen stimulator. Its vial is labelled a PLA/HA hybrid: polylactic-acid particles carried in hyaluronic acid. The hyaluronic acid hydrates the skin from the moment it is placed and then disperses; the polylactic acid stays in the dermis for longer and is what the collagen response is built around.
Two vials are held at Rewind and they are not interchangeable — the Skin vial at 50 mg and the Volume vial at 200 mg, read directly from the product labelling photographed at the clinic.
The distinction that matters at the consultation desk is between the two lines. Juvelook Skin is the lower-concentration vial used where the complaint is surface: fine lines, texture, enlarged pores, the general dullness that makeup stops covering. Juvelook Volume carries four times the polylactic acid in the same vial size and is placed deeper, where a face has lost softness rather than smoothness.
Neither line behaves like a hyaluronic-acid filler. A filler is visible when you sit up from the chair. A stimulator asks the skin to produce something over the following weeks, which is a slower proposition and a different conversation about timing — worth knowing before you book a treatment two days ahead of an event.
Indications
Rewind's own Korean material lists the reasons patients come for this product: fine lines, loss of elasticity with visible pores, uneven tone and texture, acne scarring, and a wish for facial softness that still reads as the same face. Those five map onto the two vial strengths in a way the doctor sets out at consultation.
Mechanism
Two materials go in together and leave on entirely different schedules. Understanding that gap is what stops patients from judging the result on the wrong day.
Hydration arrives with the injection and is temporary. It is a carrier and a comfort, and it is the reason skin can look plumper on the evening of the treatment in a way that has nothing to do with the collagen the product is actually there for.
The two vials share a name and little else in practice. The lower concentration is distributed superficially for skin quality; the higher one is placed deeper and in smaller total areas. Mixing up the two is the most common misunderstanding patients bring to a consultation about this product.
Published comparisons of poly-L-lactic acid and poly-D,L-lactic acid preparations examine how each behaves in tissue and how early volume differs between them. The shared finding across this literature is that the material is gradually broken down while a tissue response builds, so the endpoint is weeks away, not days.
Rewind's own page for this product records no session count and no interval. That gap is deliberate on this page: the number is set by the doctor against your skin, and a figure copied from a brochure would be a guess printed as a fact.

Judgement
Collagen stimulators are the treatment most often sold on the strength of a brand name. What decides whether one suits you is duller: how much volume has genuinely gone, how elastic the skin still is, and whether the thing you dislike in the mirror is thinning or descent.
A stimulator rebuilds body in skin that has thinned. It does not raise tissue that has descended, and adding volume to a heavy lower face can make the heaviness more obvious. Dr. Choi separates the two before a product is named.
Rewind also holds a poly-L-lactic acid line in three concentrations and a polynucleotide booster for repair-led skin complaints. Having several means the choice can be argued from your skin instead of from whichever product the clinic happens to stock.
A slow treatment needs a follow-up appointment to mean anything. The surgeon who planned the first session reviews what the skin did and decides whether a second one is warranted, which sometimes means telling you it is not.

The consultation comes first and the product is chosen in front of you. Rewind's own record for this treatment specifies an anaesthetic cream applied before injection and no sutures afterwards, which places it among the appointments patients schedule around work instead of around recovery. Sessions run in the clinic on the fourth and fifth floors of the Richro Building, by appointment, Monday, Tuesday, Wednesday and Friday until 19:00 and Saturday until 16:00.
Rewind's Korean material carries manufacturer badges for this product that this page deliberately leaves out. Regulatory approvals and clinical claims printed on promotional artwork are not evidence you can check, and reprinting them in English would give them a weight they have not earned. What is reproduced here is the labelling, the two concentrations and the clinic's own aftercare.
Case photography
Every before-and-after pair Rewind has released to date is a surgical case. Nothing has been released for this injectable, and a page that filled the frames below with a stimulator result from somewhere else would be telling you something untrue about this clinic. The frames stay as they are until the clinic photographs and consents a series of its own.
When this treatment's photographs are published they will be Rewind's own patients, taken at the same distance and under the same light on both dates, shown uncropped and with consent on file. Individual results may vary. A gradual treatment photographs poorly at two weeks and fairly at eight, so any pair published here will carry the interval between the two dates. A consultation with the doctor is required before any decision.
Pricing
Pricing is per vial, and the two lines are priced the same, so the cost of a plan follows how many vials the area needs and how many visits the doctor recommends. The third row below is the other stimulator on the shelf, listed because patients comparing the two deserve to see both numbers at once.
Listed per-vial rates, with VAT charged on top. Anything used during the session, including the numbing preparation, is already counted inside the rate shown. Multi-session plans and combinations with a device are quoted only after the doctor has examined the area, and the quote you are given in the room comes from this same list.
Suitability
Recovery
The instructions are short and the timeline is long, which is an unusual combination and the source of most disappointment when patients judge the result early. Redness or slight stinging settles within days; the part you came for takes considerably longer.
Biostimulator injection carries risk. Swelling, bruising, redness and tenderness are common in the first days; firm points or nodules in the treated plane are the complication this product class is watched for, and they are the reason placement depth and volume are a doctor's decision. Infection and vascular events are rare and serious. Report increasing pain, blanching or any lump to the clinic without waiting for the next appointment.
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 references study polylactic-acid biostimulators as a material class, including direct comparisons between the poly-L and poly-D,L forms. None of them were carried out at Rewind Plastic Surgery or on this clinic's patients, and none of their findings can be read as a forecast of what your own skin will do.
