Tear trough filler
The short answer
Tear trough filler treats one kind of dark circle: the shadow cast by a hollow between the lower eyelid and the cheek. It does not lighten brown pigment, and it does not hide veins showing through thin skin. At Rewind it is hyaluronic acid priced per 1cc syringe, and the under-eye takes some of the smallest volumes on the face, so the cost is the listed gel rate applied to what the doctor agrees with you. Rewind gives six to twelve months as the usual lifespan of its hyaluronic acid gel.
Rates are listed in the pricing section below. The under-eye is one of the three areas for which Rewind has released filler photographs of its own patients.
Most people who ask about under-eye filler describe the problem as dark circles, and many have more than one cause at once. Sorting out which part of the darkness is shadow, which is colour and which is puffiness is the first job of the consultation, because only the shadow answers to gel.
The second job is placement. Under-eye skin is the thinnest on the face, and gel sitting too close to the surface shows through it as a blue-grey tint. That effect has a name, and the whole technique is built around avoiding it.
Four kinds of dark circle
A simple test helps. If the darkness changes when light comes from above instead of straight on, part of it is shadow. If it keeps the same colour whatever the light, it sits in the skin itself.
Placement
The Tyndall effect is a bluish discolouration that appears when hyaluronic acid sits too superficially under thin skin, because the gel scatters the light passing through it. Every step of an under-eye plan is designed to keep the gel deep, soft and sparse.
Placement stays in the deeper layer beneath the muscle, well below the skin surface. This is the main protection against a visible tint and against lumps that show every time you look down.
The under-eye needs a gel that spreads smoothly. Rewind lists a domestic gel and two imported ones, and the doctor selects for softness here and explains the choice. Hyaluronic acid binds water, so overfilling can also leave the area puffy.
Under-correction can be topped up at review; over-correction under the eye is much harder to live with. The first placement is deliberately conservative.
If a blue tint or a lump does appear, hyaluronidase breaks the gel down. Dissolving is a separate item on Rewind's list and can be used on gel placed before you came to Rewind, provided it was hyaluronic acid.

Why here
The under-eye is where filler most often goes wrong in ways that show, and where the choice between gel and something else matters most.
Dr. Choi separates the causes before anything is booked. When the main problem is a fat bag or colour in the skin, he explains that gel will not deliver what you are hoping for, and nothing is injected.
Lower eyelid and midface anatomy is routine work in a lifting practice. The planes under the eye, the vessels around it and the way the cheek meets the lid are ground the injector knows from surgery.
The result is reviewed by the doctor who placed the gel, after the swelling has gone. A faint tint or a small lump found early is simpler to deal with than one discovered months later.

The eye area is examined with you sitting upright, under light from above and from the front, and photographed before any decision. If filler is right for you, the doctor marks the groove, states how much gel will be used and injects slowly, checking the surface as he goes. Eye makeup is removed first. Appointments run on Mondays, Tuesdays, Wednesdays and Fridays between 10:00 and 19:00, and on Saturdays until 16:00.
Bring details of any previous under-eye filler, including the product if you know it. Old gel that has spread or caused puffiness is sometimes dissolved first, and a new plan waits until the area has settled.
Before & After
One under-eye filler case has been released by Rewind so far. It shows a single patient photographed under the same lighting before and after, with filler as the only treatment. The second frame is held for the next under-eye case the clinic publishes.
BEFOREAFTERThe published pair shows one Rewind patient photographed by the clinic under identical lighting and conditions. Individual results may vary, and the same volume behaves differently under different skin. Bruising, swelling, a blue-grey tint, lumps, puffiness and, rarely, vascular complications can follow under-eye injection. A consultation with the doctor is required before any decision.
Pricing
Hyaluronic acid is charged per 1cc syringe on the published list. The under-eye uses very little gel compared with a chin or a fold, so the rate of the gel chosen matters more than the count. If old filler has to be dissolved before new gel goes in, that is a separate per-area item.
These are list prices without VAT, with any anaesthetic fee already inside the figure. How an under-eye plan using part of a syringe is charged is explained at consultation, before anything is opened.
Suitability
Aftercare
The under-eye bruises easily because of its thin skin and many small vessels. Rewind's guidance matches what it gives for other filler areas; the difference is that any bruise is more noticeable here.
Seek help at once for increasing pain, pale or mottled skin, or any change in vision: the vessels around the eye connect with those that supply it. Bruising, a blue-grey tint, lumps, puffiness and asymmetry are the more frequent issues, and most of them can be corrected.
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
Three references are cited: an ophthalmology review of visual loss after facial filler, a paper on why dermal filler complications occur and how they are prevented and treated, and a review of hyaluronic acid as a molecule in skin. Each concerns filler in general. None was carried out at Rewind Plastic Surgery, and none predicts the result of a given under-eye treatment.
