Filler or fat under the eye
The short answer
Neither is better for everyone. Hyaluronic acid filler is the simpler choice for a clearly defined groove: one appointment, no incision, a change seen the same day, a published duration of six to twelve months at Rewind, and the option to dissolve it with an enzyme. Micro-fat grafting moves your own fat, taken from elsewhere on the body, into the hollow during an operation. It suits wider volume loss around the eye and cheek, part of the graft is reabsorbed, the part that takes stays as living tissue, and it cannot be dissolved. Reversibility is usually the deciding point.
Sources: Rewind's hyaluronic acid filler page and filler aftercare sheet, its fat grafting fee schedule and its post-operative instructions for fat grafting.
The two options answer the same complaint, a shadowed hollow beneath the eye, with very different materials and commitments. Gel is a manufactured product that sits where it is placed until the body absorbs it. Fat is your own tissue: it has to be harvested, prepared and placed in small amounts so that the surrounding tissue can supply it with blood, and only part of it survives the move.
Neither treats the causes of dark circles that are not about volume, such as brown pigment, veins showing through thin skin or a fat bag that bulges above the groove. The comparison below assumes the examination has already found a hollow; if it finds something else, the conversation changes.
Which hollow you have
The shape and extent of the hollow matter more than its depth alone. These four patterns cover most of the faces seen for this question, and each tilts the choice one way or the other.
Side by side
The four points below are the ones patients weigh most often. They are written from what Rewind publishes for each treatment and from the general literature, and they leave the final choice to the examination.
Filler is a hyaluronic acid gel from a syringe; Rewind stocks one domestic and two imported products. A graft uses fat drawn from a donor site on your body. Rewind does not publish which donor site it uses; that is set at the examination.
Under-eye filler is given in the treatment room, often on the day of consultation. Fat grafting is surgery: harvest, preparation and placement happen in one session in theatre, on a date set for it. The clinic does not publish anaesthesia or theatre time for either.
Gel is absorbed over the published six to twelve months, and published work describes how the body breaks crosslinked hyaluronic acid down. With a graft, some fat is reabsorbed and the rest survives; the proportion varies and no figure specific to Rewind has been published.
Hyaluronidase dissolves hyaluronic acid, and Rewind lists it per area. Once fat has taken, it cannot be dissolved in the same way, so an overfilled or uneven graft is corrected more slowly.

Why here
The under-eye is a small area where a poor choice is very visible. Having both options offered by the same plastic surgeon removes the pull toward whichever one a practice happens to provide.
Rewind prices hyaluronic acid by the syringe and fat grafting by the region, and both are performed by Dr. Choi. The recommendation you receive is not limited by what is on offer.
For a first treatment of a defined groove, starting with something that can be dissolved is often the sensible route. When the hollow is wider or you have already tried gel, the surgical option is set out with its recovery.
Whether you leave with a syringe of gel or a graft date, the doctor who examined you reviews the result, and a later switch from one to the other is planned from your own chart.
On the day

The under-eye is examined upright and under different light, together with the upper cheek, to see how far the hollow extends. Earlier filler, fat bags and skin quality are noted. If filler is chosen, it can usually be given at the same visit; if a graft is the better route, you leave with a surgical plan, a quote by region and a date.
Appointments run Monday, Tuesday, Wednesday and Friday from 10:00 to 19:00 and Saturday from 10:00 to 16:00; the clinic is closed Thursday and Sunday. For a graft, leave room in your stay for the month of restrictions that follows.
Before & After
These are filler cases, the non-surgical side of the comparison. One shows the under-eye; the other shows a forehead hollow, a region where both gel and grafted fat are used for volume. In each, filler was the only treatment. Fat grafting results are not shown on this non-surgical page.
BEFOREAFTER
BEFOREAFTERBoth pairs show Rewind patients, photographed by the clinic. Individual results may vary. Bruising, swelling, a bluish tint, lumps, puffiness and, rarely, vascular complications can follow filler injection. A consultation with the doctor is required before any decision.
Pricing
The two are billed on different units, so a single sticker price says little on its own. Under-eye filler is charged per 1cc syringe, and the under-eye takes a small volume; with a published duration of six to twelve months, keeping the result over three years means several treatments, each sized at review. Fat grafting is charged per region as one operation. Rewind's schedule lists a single area, which excludes the forehead and temple, and a separate plan that includes a second session at a price below two separate operations; the portion of the graft that takes is not absorbed the way gel is, though the face keeps ageing around it.
List prices exclude VAT, and where an anaesthetic fee applies it is already inside the figure. Whether an under-eye graft counts as one area or more depends on how far the hollow extends, and that is a finding at the examination.
Suitability
Neither is offered with an active infection near the eye, during pregnancy or breastfeeding, or where a prominent fat bag is the main finding. A history of poor healing, a clotting disorder or blood-thinning medication is discussed before any graft date is set.
Recovery
Rewind's written instructions for the two differ most in length. The filler sheet is measured in days; the fat grafting sheet runs for a month, because newly placed fat depends on staying undisturbed while it establishes a blood supply.
After either treatment, report increasing pain, pale or mottled skin, or any change in vision at once. Lumps, asymmetry and prolonged swelling are the more usual problems, and they are reviewed early by the same doctor.
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
Four references are cited: a review of how crosslinked hyaluronic acid fillers are broken down in the body, safety data on a stabilised hyaluronic acid gel, a review of why filler complications arise and how they are treated, and a review of hyaluronidase. They concern hyaluronic acid filler as a class. None was carried out at Rewind Plastic Surgery, and none predicts the result of a given under-eye plan; fat grafting evidence is listed on the facial fat grafting page.
