When people compare under-eye filler in Korea, price comes down mostly to how little gel each side needs and how the clinic bills a syringe that is only partly used. Gangnam clinics quote per cc, per syringe or as a flat area fee, all before VAT, with 10% VAT added at payment. The tear trough is a thin, delicate area, so the estimate may also carry a soft gel suited to it, a review visit, and a reserve for dissolving if swelling or a bluish tint appears. This page explains each line, what research says about dose and side effects, and when a consultation should end without an injection. Amounts come from each clinic's written quote.

How little gel a tear trough takes
The hollow under the eye holds far less product than a cheek or chin. In a 2023 series in Plastic and Reconstructive Surgery – Global Open, Wilde and colleagues reviewed 1,452 tear trough treatments in 583 patients and recorded a mean first-session volume of 0.34 mL per eye, ranging from 0.1 to 1.5 mL. That is one practice's data, but it shows why one syringe often covers both sides.
That makes the billing unit matter more here than almost anywhere on the face. A per-syringe price can cover both eyes with gel to spare, while a per-cc price charges only what goes in, and some clinics use a flat under-eye fee. Before you compare one under eye filler Korea price with another, convert both to the same basis.
| Billing basis | What it covers | What to ask |
|---|---|---|
| Per syringe | One sealed syringe, often split across both eyes | Is any leftover stored for a top-up? |
| Per cc | Only the volume injected | Is there a minimum charge? |
| Flat area fee | Both tear troughs at a set dose | How much gel is included? |
| Review visit | A check after swelling settles | Is a small correction included? |

Soft gels and the cannula on an eye estimate
Doctors usually choose a softer hyaluronic acid gel for the lower lid, one that spreads smoothly and draws in little water, because firmer products can look lumpy under thin skin. Ask which product is planned and see the sealed box before treatment.
Many injectors use a blunt cannula for this area; it is rarely billed separately, but ask which instrument is planned.
Guide
Swelling, irregularities and the dissolving reserve
Side effects shape the real cost of this area. In the Wilde series, 82% reported no complication, 10% had swelling with a median duration of four weeks, 4.3% bruising, 4.6% contour irregularities and 3.3% a bluish Tyndall tint. One bleeding complication behind the eye was managed at once without lasting effect on vision. Larger volumes were linked with more swelling and irregularities, and Wilde and colleagues reported that gel was dissolved in 1.9% of eyes.
A cautious first dose with a planned review usually costs less overall than heavy filling to save a visit. In the same series, people who had needed dissolving before were more likely to need it again, so anyone with that history should ask how hyaluronidase is priced.

Old product under the eyes before a new estimate
Gel does not always stay where it was aimed. Harris and colleagues, in a 2026 ultrasound study of 126 participants in Plastic & Reconstructive Surgery, found lip filler often ended up inside muscle because the layer under the skin was less than 1 mm thick, and vertical techniques were linked with deeper placement and migration. That was a lip study, so its numbers do not transfer, but the point applies to any thin area.
If you have had under-eye treatment before, a clinic may want to locate or dissolve old product first, and a scan, a dissolving session and the wait before new gel can each be separate lines.
Guide
When the right estimate is no injection
Filler adds volume; it does not remove bulging fat pads, tighten loose lower-lid skin or fix fluid puffiness, and it can make them look worse. A careful consultation may point elsewhere, so ask whether it is charged if no treatment follows.
For a realistic under eye filler cost Korea budget, include the review, possible dissolving and a later repeat, since gel breaks down and results vary from person to person. Flying home on the day is generally possible, but bruising and swelling can last one to two weeks.

FAQ
Questions about Fillers in Gangnam
Is one syringe usually split between both eyes?
Often, yes, because each tear trough tends to need only a fraction of a syringe. In one large published series the average first dose was about a third of a milliliter per eye. Whether the split happens depends on how the clinic bills: a per-syringe price usually covers both sides, while a per-cc price charges each side by volume. Ask which applies and what happens to any gel left in the syringe.
Will a clinic charge again if swelling under the eyes lasts for weeks?
Policies vary, so ask before treatment. Prolonged swelling is the most common side effect here and often settles alone, so many clinics review it at no added fee. If the doctor decides part of the gel should be dissolved, the enzyme and visit may be billed. Get the review and dissolving policy written into the estimate, especially if you will be home when swelling peaks.
Can a bluish tint under the eye be fixed, and who pays?
Yes, a bluish Tyndall tint is usually corrected by dissolving gel that sits too close to the surface; the Wilde series in Plastic and Reconstructive Surgery – Global Open reported it in 3.3% of eyes. Some clinics treat it as aftercare, others price the enzyme per vial. Because it can appear weeks later, ask how a correction would be arranged and charged after you leave Seoul.
Is the under-eye area priced as a flat fee or by volume?
Both models exist in Gangnam, and some clinics offer either. A flat fee sets one price for both tear troughs at a planned dose, which is easy to budget but may include more gel than you need. Volume pricing charges per cc or per syringe actually used. Ask how much gel a flat fee includes, then convert each estimate to the same basis before comparing them.
Does checking for old product cost extra before re-treatment?
It can. If earlier gel is suspected, some clinics examine the area with ultrasound or dissolve old product first, and each step may be a separate line. Dissolving also means a wait before new gel, which can push treatment to a later visit. Tell the clinic about every past under-eye treatment, including brands, so the estimate reflects the real plan.
Are tear trough estimates in Gangnam written before VAT?
Yes. Cosmetic treatment prices in Korea are listed before VAT, and 10% VAT is added at payment. The tax applies to every billed line, including the gel, any dissolving enzyme and a paid review visit. When you compare two estimates, add the tax to each total first, so that the comparison reflects what you will actually pay at the desk on the day.
