Under-Eye Filler in Seoul.
A consultation-led hyaluronic acid (HA) filler treatment focused on the tear trough — the hollow that can appear beneath the eye where the lower lid meets the cheek. Under-eye filler uses an ultra-soft, low-viscosity HA gel to soften volume-related hollowing, but it does not treat pigmentation-based dark circles or significant skin laxity. Because the infraorbital and angular arteries run close to this area, exceptionally careful, vascular-aware technique matters throughout.
This page focuses specifically on under-eye filler. LOUAVE also publishes a general Dermal Fillers overview and other area-specific pages — including Cheek Filler, Nasolabial Fold Filler and Juvelook Skin Booster — for readers comparing zones or approaches.
Tear Trough Assessment
Focused on volume-related hollowing beneath the eye — this page does not cover cheek, chin, lip or nasolabial fold filler.
Tends to last a meaningful length of time, as thin, low-movement tissue in this area metabolizes gel gradually.
Planning accounts for the nearby infraorbital and angular arteries and considers whether the hollow is truly volume-related.
Understanding Under-Eye Filler
Why hollows are planned around the true cause, not the shadow alone.
The tear trough is the hollow that can appear beneath the eye where the lower lid meets the cheek. It becomes more visible with age or fatigue as under-eye fat pads shift and midface volume is lost — but not every shadow beneath the eye is caused by volume loss. Pigmentation and skin laxity can create a similar appearance, and filler does not correct either of these.
The infraorbital and angular arteries run close to this area, so exceptionally conservative gel volumes and careful, deliberate injection technique — almost always with a blunt cannula rather than a needle — matter throughout treatment.
It is equally important to understand what under-eye filler can and cannot do. It can soften a hollow caused by genuine volume loss and blend the transition between the lower lid and cheek.
It cannot correct dark circles caused by pigmentation or thin skin, and it cannot address loose or crepey skin. Overfilling can create visible puffiness or a bluish discoloration known as the Tyndall effect. Setting realistic expectations before treatment is part of a safe, honest consultation.
Confirm the true cause first, soften the hollow second.
Rather than treating every under-eye shadow as a volume problem, the underlying cause is reviewed first, so the plan supports a natural transition rather than an arbitrarily filled hollow that was never truly a volume issue.

How Under-Eye Filler Works
Concept 01
Concept 02
Concept 03
Concept 04
One zone, planned around the true cause of the hollow.
A balanced result depends on understanding whether the hollow is deepened mainly by loss of volume directly beneath the eye or by volume loss in the adjacent cheek. During consultation, the doctor assesses the trough, the midface and the infraorbital vascular path, then plans an exceptionally conservative gel volume and injection points around this zone as a whole, not the hollow alone.
Hollow-Specific Softening
Ultra-soft gel placed directly beneath the trough can soften its visible depth and blend the transition between lid and cheek.
Malar Support Consideration
When cheek volume loss is contributing to the hollow, restoring midface support can indirectly soften the trough as well.
Vascular-Aware Technique
The infraorbital and angular arteries are mapped before injection, with a blunt cannula strongly favoured to reduce the risk of vascular compromise.
Conservative, Reversible Volume
Very small volumes are placed and reviewed in stages, and hyaluronidase remains available to dissolve HA gel if a problem is ever suspected.
Concerns Under-Eye Filler May Address
Tear trough and midface concerns, reviewed individually at consultation.
The concerns below are specific to the tear trough and adjacent midface. Concerns in other areas, and concerns unrelated to volume loss, are addressed differently and are explored on their own dedicated pages.
Visible Tear Trough Hollow
A hollow beneath the eye caused by genuine volume loss can be given subtle, proportionate softening through conservative gel placement.
Trough & MidfaceShadowing Under the Eyes
A visible shadow cast by a deep hollow, particularly under certain lighting or angles, can be softened with careful volume.
Trough & MidfaceAge-Related Midface Volume Loss
Cheek volume that has thinned with age, contributing to a deeper trough, can be addressed to restore a softer transition.
Trough & MidfaceHollow Asymmetry
Small differences in hollow depth or position between the left and right side can sometimes be visually balanced.
Trough & MidfaceTired-Looking Appearance
A persistently tired look driven by volume-related shadowing, rather than pigmentation or skin laxity, may be softened with careful filler.
Trough & MidfaceCombined Cheek-and-Trough Volume Loss
When both the cheek and tear trough show volume loss, a broader midface plan may be discussed alongside direct trough treatment.
Trough & Midface Treatment Philosophy
Understand the cause first, then soften with exceptional care.
Because the infraorbital and angular arteries run near this area and the overlying skin is exceptionally thin, the approach begins with cause assessment and vascular safety before any volume is added.
Cause-Aware Assessment First
Hollow depth, midface volume, pigmentation and skin quality are reviewed together before any attention turns to overall gel volume, so the plan serves the true cause.
Whole-midface assessment first
Volume vs. pigment vs. laxity distinguished
Individualised, not formulaic
Cause before hollow

Ultra-Conservative, Reversible Volume
Ultra-soft HA gel is placed in very small amounts and reviewed in stages, rather than placed all at once, and can be dissolved if ever needed.

LOUAVE Treatment Process
A structured plan built around caution and the true cause.
The process below is specific to under-eye filler, from initial cause assessment through to ultra-conservative injection and immediate review.
Consultation & Cause Assessment
The doctor examines hollow depth, cheek volume, pigmentation and skin quality, and discusses realistic goals for softening the trough.
Whole-midface assessmentVascular Mapping & Point Planning
Injection points are carefully mapped along the trough and cheek, with technique and volume adjusted around the infraorbital and angular arteries.
Vascular-aware point mappingUltra-Soft, Cannula-Led Injection
Ultra-soft HA gel is placed in very small, controlled amounts, almost always via a blunt cannula, building softening gradually rather than in one large volume.
Cannula-led techniqueReview & Symmetry Check
Hollow softening and facial symmetry are checked immediately after injection, before a broader review of swelling and shape follows over the coming days.
Immediate symmetry check Results & Development
Day 0
Day 1–3
Week 1–2
Ongoing
Visible immediately, settling within about two weeks.
The change in hollow depth is usually visible right away, though initial swelling — which tends to be more noticeable in this thin-skinned area than elsewhere on the face — can slightly overstate the final result. Some settling and gradual refinement continues over the first couple of weeks as the gel integrates with surrounding tissue.
Injection appointment
The change in hollow depth is visible immediately, though swelling can make the result look softer or puffier than the eventual outcome.
Peak swelling settles
The area is typically most swollen in the first one to two days, with swelling, tenderness or minor bruising reducing noticeably over these first few days.
Final softening becomes visible
Most visible swelling has resolved by around one to two weeks, when the settled trough appearance can be properly assessed.
Meaningful duration
Because this low-movement area metabolizes gel gradually, results often last a meaningful length of time, though an eventual touch-up may still be discussed.
International patients should allow one to two weeks for swelling to fully resolve before requesting adjustments or leaving Seoul.
Suitability & Screening
Suitability is confirmed through an honest health review.
Treatment may be modified, delayed or declined when certain health factors are present, or when the proposed plan is not appropriate for your under-eye goals.
Under-eye filler may be discussed when:
- You notice a visible hollow beneath your eyes caused by genuine volume loss.
- You notice a shadow under your eyes that worsens under certain lighting or angles.
- You feel your midface has lost volume with age, contributing to the hollow.
- You notice mild asymmetry in hollow depth between the left and right side.
- You understand this treatment does not correct pigmentation or lax skin, and accept what filler can and cannot change about this area.
Tell the doctor before treatment about:
- Pregnancy, planned pregnancy or breastfeeding.
- Any known allergy history, including to hyaluronic acid or anaesthetic products.
- Active infection near the eyes or midface, or any active eye conditions.
- Autoimmune conditions or a history of bleeding disorders and blood-thinning medication.
- Previous filler or surgery in the under-eye or cheek area, as altered anatomy affects planning and technique here.
Aftercare
Simple precautions support a smooth response.
Follow the instructions provided by the treating doctor. Advice may vary according to the volume placed, gel used and other treatments performed at the same appointment.
Manage Swelling Gently
Use a cold compress as advised by the clinic, applied gently given how thin the skin is in this area, to help reduce swelling.
Avoid Rubbing Near the Eyes
Avoid rubbing, massaging or applying pressure near the eyes unless the clinic specifically instructs you to do so.
Avoid Eye Makeup Immediately After
Wait for the period advised by the clinic before applying makeup directly over the treated under-eye area.
Avoid Strenuous Exercise
Skip intense exercise and heavy lifting for approximately twenty-four to forty-eight hours after treatment.
Safety Information
General information, not a substitute for consultation.
This page provides general educational information about under-eye filler as a treatment. It does not replace an individual medical consultation, and effects, recovery and suitability vary between patients.
Seek immediate attention for:
- Any change in vision, including blurring or vision loss — this is a rare but medically recognised emergency in periorbital filler and requires immediate emergency care, not a wait-and-see approach.
- Skin blanching or whitening at or around the eye or cheek — this can be an early sign of vascular occlusion and requires immediate attention.
- Severe or disproportionate pain at the injection site, beyond the expected mild discomfort.
- Mottled or dusky discoloration spreading from the treated area — treat this as urgent given the infraorbital and angular arteries' proximity here.
- Increasing redness, heat, discharge, fever, or lumps and significant asymmetry that do not settle within the expected timeframe.
Because the infraorbital and angular arteries run close to the tear trough, and this area's vascular anatomy connects toward structures around the eye, signs of possible vascular compromise are treated with the highest urgency here. Contact the clinic immediately, or seek emergency care, if any of the above occurs — early recognition and prompt treatment, including hyaluronidase if needed, matter significantly for this area.
Frequently Asked Questions
Questions about under-eye filler.
Gel selection, technique, expected timelines and suitability for this area are confirmed during consultation.
What is under-eye filler, and what can it change?
Under-eye filler is a non-surgical treatment that uses an ultra-soft hyaluronic acid gel to soften the tear trough hollow beneath the eye, sometimes alongside midface cheek support. It only addresses hollowing caused by genuine volume loss, not pigmentation or skin laxity.
Will under-eye filler fix my dark circles?
Only if the dark appearance is caused by a shadow from volume loss. Dark circles caused by pigmentation or very thin, translucent skin are not improved by filler, and a doctor will assess which cause applies to you before recommending treatment.
Can under-eye filler fix asymmetric hollows?
Under-eye filler can often visually balance mild asymmetry in hollow depth between the left and right side by adjusting volume and placement. The degree of correction possible depends on individual anatomy and is assessed at consultation.
Why is under-eye filler considered a notable vascular risk area?
The infraorbital and angular arteries run close to the tear trough, and the skin here is exceptionally thin, so conservative volume, careful cannula-led technique and an experienced injector matter meaningfully in this area — more so than in many other facial zones.
How long does under-eye filler last?
Duration varies by individual, but under-eye filler often lasts a meaningful length of time — commonly around nine to fifteen months — since this low-movement area metabolizes gel gradually.
Does under-eye filler hurt?
Most patients describe brief, mild discomfort during injection. A topical numbing cream or the gel's built-in local anaesthetic can help minimise sensation, and any tenderness typically settles within a short period afterward.
What is the downtime after under-eye filler?
Many patients return to normal activities the same day, though swelling or bruising around the eyes is common in this thin-skinned area and can be noticeable for several days to around one to two weeks while the final result settles.
Is under-eye filler safe?
Under-eye filler can be performed safely, but the nearby infraorbital and angular arteries mean ultra-conservative volume, careful cannula-led technique and treatment by an appropriately experienced injector matter significantly here. Risks exist and are discussed individually during consultation and covered in the safety information on this page.
Can under-eye filler be combined with other treatments, or reversed if there is a problem?
Yes, under-eye filler is sometimes discussed alongside cheek filler or a skin booster as part of a broader plan, with sequencing confirmed at consultation. Because it is HA-based, it can also be dissolved using hyaluronidase — an important tool in this area if a vascular problem is ever suspected.
What is the Tyndall effect, and can it happen with under-eye filler?
The Tyndall effect is a bluish discoloration that can appear when HA gel is placed too superficially in thin under-eye skin. It is a known risk specific to this area, which is why an ultra-soft gel, conservative volume and correct injection depth are prioritised.

Important treatment information
This page provides general educational information about under-eye filler treatment and does not replace an individual medical consultation. Dermal filler products have product-specific formulations, indications, contraindications, storage requirements and regulatory status that may vary by country. The infraorbital and angular arteries run close to the tear trough, the overlying skin is exceptionally thin, and the conservative volumes and cannula-led technique used here reflect that anatomy. Treatment must be selected and performed by an appropriately experienced medical professional after reviewing under-eye and midface anatomy, skin quality, relevant vascular anatomy, previous filler or surgery, health history, medications, allergies and informed consent. Temporary effects may include injection-site pain, redness, swelling, tenderness or bruising. Other possible effects include asymmetry, palpable lumps or nodules, a bluish Tyndall discoloration, and an unfamiliar appearance in or near the treated area. Rare but serious complications include vascular occlusion, skin necrosis, infection and delayed inflammatory reactions; in extremely rare cases, vascular complications in this area have been associated with changes in vision. Because of this area's vascular anatomy, any such signs should be treated as a medical emergency. Seek immediate medical care for skin that becomes unusually pale, dusky, mottled or increasingly painful, any change in vision, signs of infection, or severe allergic symptoms. Under-eye filler is not intended to correct pigmentation-based dark circles or skin laxity. Results, symmetry, longevity, onset and maintenance requirements vary and cannot be guaranteed.
