Under-eye filler in Korea means a small amount of soft hyaluronic acid gel placed along the tear trough to soften a hollow groove that casts a shadow below the lower lid. It suits a true hollow with reasonably firm skin, and helps far less with puffy fat bags, brown pigment or very thin, crepey skin. In Gangnam a session usually takes under an hour including numbing, with a needle or blunt cannula. Bruising or swelling for several days is common. Less common problems include a bluish Tyndall tint, lumps, long-lasting puffiness and, rarely, a blocked tear duct or a vascular event.
Guide
Is it a hollow, a bag or a shadow of color?
Dark circles have several causes, and gel only addresses one of them. A careful doctor looks at you upright and under overhead light, presses the lower lid gently and asks you to look up, because bulging fat moves while a hollow stays put.
If the main issue is puffiness, adding volume next to it can make the area look fuller and heavier. Pigment and visible vessels need laser, topical care or simple concealer instead.
| What you see | Usual cause | Does gel help? |
|---|---|---|
| Groove from inner corner toward the cheek | Volume loss over bone | Often, in small amounts |
| Puffy pad that bulges more in the morning | Fat prolapse or fluid | Rarely, may worsen it |
| Brown or purple tone with no groove | Pigment or vessels | No |
| Fine creasing on a thin lid | Skin quality | Limited, skin treatments fit better |

Needle or cannula under the eye
Both tools are used, and each carries a different trade-off. In a 2023 meta-analysis of prospective clinical trials in the Journal of Cosmetic Dermatology, Nikolis and colleagues found that infraorbital injections with a needle had a significantly higher rate of bruising, while cannula injections had a significantly higher rate of swelling.
The authors suggest discussing this before treatment and note that it is usually wise for an injector to master one technique before adding another. So the useful question in a consultation is less which tool is used and more which one this doctor uses routinely for the lower lid.
Guide
Tyndall tint, lumps and lingering puffiness
The lower lid has some of the thinnest skin on the face, so problems that stay hidden elsewhere can show here. Most are manageable, and hyaluronic acid can be dissolved with hyaluronidase if needed.
- Tyndall effect: gel placed too close to the surface scatters light and looks bluish under thin skin
- Lumps or a visible ridge: uneven spread, too much product or a firm gel in the wrong layer
- Puffiness that lasts weeks: gel draws water, and some people hold fluid in this area
- Bruising: common for a week or so, especially with needle technique
- Vascular event: rare, but arteries near the eye link to the vessels of the eye, so sudden pain, pale skin or any vision change needs urgent care
Guide
A rare complication: a blocked tear duct
Watering from one eye after tear trough treatment is not always simple irritation. In a 2019 report in Ophthalmic Plastic and Reconstructive Surgery, Kalin-Hajdu and Kersten described nasolacrimal duct obstruction caused by tear trough hyaluronic acid, which they believed was the first such case reported. The blockage cleared at once after hyaluronidase was irrigated into the tear drainage system.
The lesson for a traveler is practical. Persistent tearing on the treated side is worth reporting to the clinic before you fly, and a doctor at home should hear that you had filler near the inner corner.

Planning tear trough treatment on a Gangnam trip
Book the consultation early in the stay so there is time to say no, or to start with less. A conservative first dose and a review after swelling settles, often about two weeks later, gives a cleaner result than filling fully in one go. If your trip is too short for a review, a smaller dose is the safer plan.
Ask for the product name, batch number and volume per side in writing, and keep it with your travel documents.

FAQ
Questions about Fillers in Gangnam
Is under eye filler in Seoul a fix for dark circles?
It helps only when the darkness comes from a shadow cast by a hollow groove. Gel lifts the floor of the groove so less shadow forms, but it does not change brown pigment, visible purple vessels or puffy fat pads. Many people have a mix of causes. A consultation that names the main cause, and sometimes suggests laser or skin care instead, is a good sign that the plan fits you.
How long does tear trough gel usually stay?
Gel under the eye often lasts longer than in the lips, commonly a year or more, because the area moves little. Some people still have traces after several years, which is one reason doctors start with small amounts. Soft gels designed for this area are the usual choice. Results vary from person to person, so mention any earlier under-eye treatment even if you think it has gone.
Does an under-eye injection hurt?
Most people feel pressure and mild stinging rather than strong pain. Numbing cream is applied for about 20 to 30 minutes, and many soft gels contain lidocaine. A cannula often needs only one small entry point per side, which some people find more comfortable. Expect tenderness and possible bruising for several days, and use a cool compress wrapped in cloth rather than ice placed directly on the lid.
Can I wear eye makeup or contact lenses afterward?
Contact lenses are usually fine the same day if you insert them without pulling hard on the lower lid. Leave makeup off the entry points for about 24 hours to lower the risk of infection, and choose clean brushes when you restart. Avoid rubbing the eyes or pressing on the treated area for several days. Ask the clinic about glasses or goggles if you plan to swim or dive soon after.
Who is a poor candidate for tear trough gel?
People with large fat bags, marked skin laxity or long-standing morning puffiness tend to look worse with added volume. Pregnancy, active eye infection, recent eyelid surgery and a history of severe allergy are reasons to wait or discuss carefully. Someone who mainly has pigment is better served by other treatments. In these cases lower eyelid surgery, laser or simply no treatment can be the more suitable advice.
When should I contact the clinic urgently after treatment?
Contact the clinic straight away for any change in vision, severe or rising pain, or skin that turns pale, gray or blotchy, and seek emergency care if vision is affected. Report steady watering from one eye, a hard lump or a bluish tint within the first days too. Hyaluronidase works in many of these situations, and earlier treatment usually means a simpler fix before you fly.
