Under-Eye Filler in Cheongdam, Seoul

The thinnest skin on the face sits over the most unforgiving anatomy on the face. That combination is why under-eye filler is quoted in half-cubic-centimetre units here, and why a good number of the people who ask for it are advised against it.

About

What under-eye filler is placed into

Under-eye filler is a small deposit of hyaluronic acid placed into the depression between the lower lid and the cheek, so that light stops collecting in a groove and casting a shadow. The product held on our list for this area is Eye Light, quoted at ₩500,000 (≈ $355) for 0.5cc. It is a geometry correction and it changes nothing about skin colour.

Two facts about that sentence decide almost everything else on this page. First, the volume is tiny: half a cubic centimetre is a fraction of what a cheek or a chin takes, and the difference between a correction and an overcorrection here is measured in fractions of that. Second, the tissue is transparent enough that whatever sits underneath shows through, which is why product choice and depth are a clinical decision and never a preference.

Dear Clinic publishes a single written rate for the eye-area unit, the same figure for Korean patients and international visitors. If this area turns out to be the wrong place to inject, the alternative we run is described further down, and the full range of areas sits on the dermal filler page.

Illustration of tissue layers used to explain deep, mid and superficial placement in under-eye filler planning
Deep, mid and superficial are three different decisions. Under the eye, only one of them is usually correct.
Anatomy

Three findings under the lower lid that look the same in a mirror

Patients arrive describing one problem. The examination usually finds one of these three, and they are not treated the same way.

FINDING 01

A groove running from the inner corner

A true depression where the lower lid meets the cheek, bounded by ligament below. It deepens with age as the tissue above it thins. This is the finding a small hyaluronic-acid deposit is designed for, and it is the one that photographs so badly under overhead light.

FINDING 02

The roll of muscle below the lash line

A soft ridge that appears when you smile, sitting immediately under the lashes and formed by the muscle that closes the eye. Some people want it enhanced and some want it softened, and neither request is the same operation as filling a groove beneath it.

FINDING 03

Orbital fat pushing forward as a bag

A convexity that stays when you lie down, produced by fat that has moved forward through weakened tissue. Adding volume below a bag makes the bag read more sharply. This finding belongs to a surgical opinion, which this clinic does not provide.

Most faces present two of the three at once, in different proportions. The proportions decide whether anything is injected at all, and the examination that sorts them takes about half an hour.

A note on product naming: Eye Light is the eye-area item on our published list, and which of the findings above it is placed for in your case is confirmed by your director in person. We deliberately do not print a fixed indication for it on this page.

Product Choice

Why the under-eye takes a thin hyaluronic acid

Hyaluronic acid is one material family with a wide range of engineering inside it. Gels built to hold an outline are firm and are placed deep, where firmness is invisible. The under-eye needs the opposite: a low-viscosity preparation that spreads smoothly in a thin plane and does not read as an edge under skin you can almost see through.

The physical properties that separate one hyaluronic-acid product from another are documented in the peer-reviewed literature, and a 2019 paper on the rheologic and physicochemical differences between injectable products is listed at the foot of this page. It is the reason a clinic cannot simply use whatever syringe is open. A firm gel placed under the lower lid can stay visible as a ridge long after the swelling has gone.

There is a second optical problem that only happens here. Hyaluronic acid placed too superficially under very thin skin can scatter light towards the blue end, giving a faint bluish cast known as the Tyndall effect. It is a placement problem before it is a product problem, and the correction is enzymatic, because waiting does not resolve it. That enzyme, hyaluronidase, is stocked in this building.

If you are weighing an injectable against a skin treatment for this area in general terms, the comparison is set out on the filler versus skin booster page, and the wider injectable comparison sits on the botox versus filler page.

The Dear Method

How an under-eye plan is designed and placed at Dear

The same four signature steps used across our filler work, applied to the smallest volume on the list.

STEP 01

Dear Shape reads the whole mid-face

The EVE Muse 3D capture and five-light-source AI analysis are read first, then Dear Shape sets the target form before any syringe is chosen. Under the eye that means judging the groove against the cheek that supports it, because a flattened cheek often creates the shadow that a patient attributes to the lid.

STEP 02

Dear LayerFill assigns the plane

Dear LayerFill assigns deep, mid and superficial doses. Here the answer is usually deep and nothing else, placed against bone, well below the visible layers, at 0.1 cc precision.

STEP 03

Dear BalanceControl checks both eyes

Dear BalanceControl compares each side against the whole face. Eyes are rarely symmetrical to begin with, and the plan records the difference before treatment so that the result is read against reality.

STEP 04

Dear LineFit finishes the transition

Dear LineFit refines the finishing line where the correction meets untreated tissue, so that the edge of the deposit is not a line you can find in raking light.

Under-correcting and reviewing is the policy in this area more than any other. Adding a further fraction of a cubic centimetre at review takes minutes; dissolving an overcorrection is a separate appointment and a separate injection.

Safety

The rules that govern injecting beside the eye

Mapped danger zones. The vascular anatomy of this region is documented in the surgical literature on facial danger zones, and that mapping is what the injection plan is drawn against. It is listed in the references below.
The serious risk, named. Vascular occlusion is the event every injector plans to avoid, and the ophthalmologic literature includes a review of visual loss following aesthetic facial filler injection. We name it here because a page that discusses this area and omits it is selling, not informing.
Reversal held on site. Hyaluronidase dissolves hyaluronic acid and is kept in the building. Its use in aesthetic practice has its own published review, also listed below.
Director-performed, without exception. The doctor who examined you is the doctor who injects you. Nothing about this area is delegated, and the review afterwards is with the same person.
Small volumes, slow pace. The unit on the price list is 0.5cc for a reason. Sessions here are unhurried, and more than one appointment is normal for a result that looks like nothing was done.

The commoner events are less dramatic and worth planning around: bruising, swelling that takes longer to settle here than on the rest of the face, visible lumps or nodules if placement or volume is wrong, and asymmetry between the two sides. All of them are reviewed at the follow-up appointment your director schedules.

Suitability

Who under-eye filler does not suit

This is the section most filler pages leave out. A meaningful share of the people who ask us for this treatment are advised against it, and being told so at the consultation is cheaper than being told so at the review.
A pronounced fat bag. Where the convexity persists lying down, adding volume beneath it usually sharpens the contrast. Filler is not the right treatment for that finding and we decline to place it.
Skin that swells easily. Under-eyes that puff after salt, alcohol or a poor night's sleep hold fluid readily, and hyaluronic acid attracts water. Where that tendency is marked, the honest advice is to leave the area alone.
Darkness that is pigment or vessels. Colour that stays when the skin is stretched is not shadow, and no amount of volume lightens it. That belongs to a laser assessment.
Very thin, lax skin with no groove. Where the complaint is crepey texture with no depression underneath, thickening the skin is the sensible route and we quote the PDRN eye line instead at ₩400,000 (≈ $285) for 2cc. The wider treatment is covered on the Rejuran page.
General injectable exclusions. Pregnancy and breastfeeding, active infection or inflammation at the site, and known sensitivity to a product component all rule out treatment. Blood thinners, autoimmune conditions and recent injectable work in the same plane are reviewed before anything is agreed.

Dear Clinic carries the full hyaluronic-acid range, the regenerative boosters and the lifting platforms in one building, so a director who sends you to a different shelf loses nothing by doing it. Filler here is treated as precision craft, and the craft includes knowing when to put the syringe down.

Pricing

How much does under-eye filler
cost in Seoul?

At Dear Clinic the eye-area filler unit is ₩500,000 (≈ $355) for 0.5cc of Eye Light, published openly and charged at the same rate for Korean residents and international visitors. Where the examination points away from filling, the PDRN eye line is ₩400,000 (≈ $285) for 2cc. Both figures are quoted to you before anything is opened.

Published rates as of September 2026, shown in KRW with an approximate USD conversion for reference; KRW is what you pay, with no visitor surcharge of any kind. If a second fraction of a unit is needed at the two-week review, you are told the cost before it is used, and it is frequently not needed at all.

Other areas are quoted separately by product and volume on the published price list, and multi-area designs are set out on the full face filler page.

Aftercare

The days after an under-eye filler appointment

Day one. Expect swelling and the possibility of a bruise. This area bruises more readily than the cheek or the chin because the skin is thin and the tissue beneath it is vascular. Cold, gentle pressure and a high pillow are the whole protocol.
The first week. Avoid rubbing the area, sleeping face down, saunas, heavy exercise and alcohol. Keep make-up light over the entry points for the first day, and do not massage the site unless your director has specifically asked you to.
Reading the result. Nothing here should be judged before the swelling has gone. We review at around two weeks, which is when the true shape is readable, and small refinements are planned at that appointment.
Contact us immediately if. Pain increases instead of fading, the skin turns pale, dusky or mottled, or vision changes in any way. These are the signs the safety literature is written about, and the response is time-critical.
Before you fly. There is no medical restriction on flying after this treatment. The practical advice is to leave several days if you would rather not travel with a visible bruise under one eye, and your director will plan the date against your itinerary.

This page carries no before-and-after gallery because we hold no audited in-house case set for the eye area, and labelling a photograph from another treatment as an under-eye result would be a misrepresentation. When a verified set exists it will appear here with the interval and the single treatment named.

FAQ

Under-eye filler in Seoul, answered

How much is under-eye filler in Korea?
At Dear Clinic the eye-area unit is ₩500,000 (≈ $355) for 0.5cc of Eye Light, published on the price list and identical for Korean patients and international visitors. KRW is the payable amount and the USD figure is shown for reference only. Most plans in this area use one unit; the total is agreed with you before anything is opened.
Why is under-eye filler sold in 0.5cc when other areas are sold in 1cc?
Because the correct dose here is small, and pricing in half-unit steps stops the smallest area on the list being quoted against the largest. A cheek or a chin can take a full cubic centimetre or more without looking treated. Under the eye, that volume would be a visible error. The unit on the sheet reflects the anatomy, and it is no kind of discount structure.
How long does under-eye filler last?
Hyaluronic acid is gradually broken down by the body, and nothing in this category is permanent. Duration varies with the product, the plane it sits in, how much movement the area sees and individual metabolism, so a conservative range is given to you in person instead of a number published for everyone. The area is reviewed before any repeat is proposed.
Does under-eye filler hurt?
Comfort measures are confirmed at consultation, and many hyaluronic-acid products contain a local anaesthetic themselves. Most people describe pressure more than pain. The area is sensitive, so the pace is slow and you are asked how it feels as it goes; tell your director immediately if anything is sharp or if pain increases.
What is the Tyndall effect, and how do you avoid it?
It is a bluish cast that can appear when hyaluronic acid sits too superficially under very thin skin, because the gel scatters light towards the blue end of the spectrum. Avoiding it is a matter of depth, product selection and dose. If it does occur, hyaluronidase dissolves the deposit, and that enzyme is kept in this building for exactly that reason.
Can under-eye filler be dissolved if I dislike it?
Yes. Hyaluronic acid is reversible with hyaluronidase, which has its own published review in the aesthetic literature listed at the foot of this page. Dissolving is a separate appointment and a separate injection, and the area is then left to settle before anything further is considered. This reversibility is one of the reasons hyaluronic acid is used here instead of a permanent material.
Will filler fix my dark circles?
Only if the darkness is shadow. Filling a groove changes how light falls, which removes shadow, and it does nothing at all to pigment sitting in the skin or to the bluish tint of vessels showing through. A simple stretch test at consultation separates the two, and where the problem is colour instead of contour you will be quoted for something else.
What happens if I have eye bags instead of a hollow?
You are told so, and we do not inject. A bag is fat that has moved forward, and adding volume underneath it commonly makes the convexity more obvious. The route for that finding is a surgical opinion, which this clinic does not offer, and saying that at the first appointment is cheaper for you than a course that cannot work.
How much swelling should I expect, and for how long?
More than you would expect from the volume involved, and it varies widely between people. The area holds fluid easily, so swelling in the first days is normal and sometimes uneven between the two sides. Judging the result before around two weeks is the commonest reason patients worry unnecessarily. Sleep with the head raised and keep salt low for the first days.
Can I have under-eye filler on the same day as my consultation?
Usually yes, once the examination confirms that filling is the right answer. Diagnosis and consultation take roughly half an hour and treatment can follow immediately. The thing to plan around is the bruising risk more than the appointment time, so tell us on the form how many days you have before any event or flight.
Is under-eye filler safe?
Every injection near the eye carries real risk, and the serious one is vascular. The published literature includes an anatomical mapping of facial danger zones and an ophthalmologic review of visual loss after facial filler injection, both listed below. Our protocol answers that literature with a director-performed injection by the doctor who examined you, small volumes placed deep, and hyaluronidase on site.
I am visiting Seoul briefly — how should I plan this, and how do I book?
Plan the appointment early in the trip so that a review is possible before you leave, and leave several days before anything photographed. Send the consultation form with your arrival and departure dates and, if possible, one photograph taken under an overhead light. We reply in English as soon as possible, hold the slot without a deposit, charge visitors the same published rates, and are open 365 days a year including Sundays and public holidays.
