Under-Eye Filler in Korea: Benefits, Risks & Recovery

October 25, 2026

Under-eye filler, also called tear trough filler, is one of the most requested “look less tired” treatments in Korea. Done well, it softens the hollow that casts a shadow under the eyes and makes the whole face look more rested. Done on the wrong person, or with too much product, it can look puffy or blue. This guide explains who under-eye filler suits, the real risks of this delicate area, what it costs in Busan and what recovery looks like for a visitor.

Quick answer: Under-eye filler places a small amount of soft hyaluronic acid in the hollow between the lower eyelid and the cheek, reducing the shadow that looks like a dark circle. It takes about 10–20 minutes after numbing cream, bruising or mild swelling for a few days is common, and results usually last about 9–12 months. It only helps shadow-type dark circles, not pigment or puffy bags. In Seomyeon, Korean under-eye filler starts from KRW 150,000 before 10% VAT.

What is under-eye filler?

The tear trough is the groove running from the inner corner of the eye down towards the cheek. With age, or simply because of your bone structure, it can deepen and cast a shadow. Under-eye filler uses a soft hyaluronic acid (HA) gel, placed deep and in small amounts, often with a blunt cannula, to lift the groove from beneath and smooth the transition into the cheek.

It is not the same as aegyo-sal filler, the Korean treatment that creates a soft, plump roll just under the lash line when you smile. Tear trough filler treats a hollow; aegyo-sal filler adds a feature.

Benefits: what it can and cannot fix

  • Softens under-eye hollows so the eye area looks smoother.
  • Reduces shadow-type dark circles and the tired look that comes with them.
  • Quick and reversible: HA can be dissolved with an enzyme if needed.

Dark circles have several causes: a hollow casting a shadow, brown pigment, visible blood vessels or puffiness. Filler only helps the first. A simple test is to look up towards a light: if the darkness fades, a hollow is likely involved. Many people have more than one cause.

Who should choose something else

  • Brown pigment: filler will not lighten it; a laser such as pico toning may be considered.
  • Prominent bags or frequent puffiness: filler can make these look worse and may be advised against.
  • Fine, crepey under-eye skin: a skin booster such as Rejuran Healer targets skin quality instead.
  • An eye infection, recent eye surgery or pregnancy: treatment waits.

Risks to understand

Under-eye skin is thin, so this is an area for precision and restraint.

  • Bruising and swelling are more likely than elsewhere and usually settle within a few days.
  • Bluish tint or a visible ridge (the Tyndall effect) can happen if filler sits too close to the surface. It can be corrected by dissolving.
  • Puffiness can develop because HA attracts some water, especially with larger amounts.
  • Lumps or unevenness often soften as the filler settles.
  • Rare but serious: filler can block a blood vessel. Severe pain, skin colour change or any change in vision needs urgent attention: contact the clinic or seek emergency care immediately.

Careful depth, small amounts, slow injection and choosing the right patient reduce these risks. Ask how complications are managed before you decide.

How much does under-eye filler cost in Busan?

The doctor confirms the amount you need after examining you. Prices checked October 2026; they exclude 10% VAT, are paid in won at the clinic on the day, and prices can change, so confirm the current price on WhatsApp. When comparing quotes, ask which product is used, how much is included and whether VAT is included.

What happens on the day

  1. Message ahead. Send a straight-on daylight photo and one looking slightly up, without makeup, and mention any eye surgery or previous under-eye filler.
  2. Consultation. The doctor checks whether your dark circles come from a hollow, pigment or puffiness, and assesses skin thickness and lower-lid laxity.
  3. Numbing. Numbing cream is applied for about 20–30 minutes and the hollow is marked while you sit upright.
  4. Treatment. Small amounts go in slowly over about 10–20 minutes. Most people feel pressure rather than sharp pain.
  5. Check. Symmetry is checked before you leave.

Results and recovery timeline

  • Immediately: the change is visible, often with some swelling.
  • First 24–72 hours: a small bruise or morning puffiness is not unusual.
  • Days 2–7: swelling and bruising settle.
  • Weeks 2–4: the filler softens; this is the time to judge the result.
  • Months 9–12: the filler is gradually absorbed and a top-up can maintain it.

Aftercare tips

  • Do not rub your eyes or press on the area.
  • Skip saunas, jjimjilbang, hot baths, alcohol and hard exercise on the day, and avoid strong heat or massage on the area for 1–2 weeks.
  • Eye makeup and concealer are usually fine from the next day, applied gently.
  • Contact the clinic if lumps, asymmetry or discomfort persist.

Planning under-eye filler around a trip

Sightseeing is fine the same day, and sunglasses help if you bruise. Because bruising is more likely here, avoid booking it right before important photos, and if possible keep a day or two before a long-haul flight so the clinic can check you. Tell the doctor your flight date at the consultation.

Under-eye filler vs other under-eye treatments

  • Tear trough filler : HA fills the hollow. Best for: shadow-type dark circles. About 9–12 months.
  • Aegyo-sal filler : HA creates a soft roll under the lashes. Best for: a rounder, softer smiling eye.
  • Rejuran Healer : PN skin booster. Best for: thin, crepey under-eye skin; usually a course of sessions.
  • Pico toning : laser for pigment. Best for: brown dark circles.

Frequently asked questions

Will under-eye filler fix my dark circles?

Only if they are caused by a hollow casting a shadow. Pigment, visible veins and bags need different approaches.

Why does under-eye filler sometimes look blue or puffy?

Usually because it sits too close to the surface or too much was used. Small amounts placed deeper reduce this, and HA can be dissolved if needed.

Can old under-eye filler be corrected?

Often, yes. If previous filler looks puffy or uneven, dissolving it before any new plan may be suggested.

Ultherapy is one of the most requested non-surgical lifting treatments in Korea, and Busan has become a popular place to have it done, especially for visitors who want to combine a treatment with a city break by the sea. This guide explains how Ultherapy works, who it suits, what it costs in Busan, and what recovery really looks like, so you can decide whether it fits your goals and your travel plans. Quick answer: Ultherapy uses focused ultrasound, guided by real-time imaging, to heat the deep supporting layer of the face (the SMAS) and trigger new collagen. A session takes about 30–60 minutes after numbing cream, there is usually no downtime, the lift builds over 2–6 months, and results typically last 6–12 months. In Busan, packages generally start from around KRW 790,000 before 10% VAT. What is Ultherapy? Ultherapy (often called Ulthera) is a micro-focused ultrasound device made by Merz Aesthetics. Like other HIFU treatments, it delivers concentrated ultrasound energy beneath the skin. What sets it apart is its built-in imaging: the practitioner can see the layers of the skin on screen and place each line of energy at the intended depth, including the SMAS, the same layer that is tightened in a surgical facelift. Each line creates tiny heated points that contract the tissue and start the body's collagen renewal process. Rather than an instant change, the skin firms and lifts gradually over the following months. Benefits of Ultherapy Reaches the deep support layer. Energy can be delivered down to the SMAS, which is why Ultherapy is used for sagging rather than surface texture alone. Imaging-guided precision. Seeing the tissue before each line helps place energy where it is needed and away from bone. No incisions and no downtime. Most people return to their day straight away. Natural, gradual change. The lift develops as collagen rebuilds, so results look like your own face, only firmer. One session a year for many people. A single treatment is usually enough for a visible change, repeated every 6–12 months. Who is a good candidate? Ultherapy tends to suit people in their 30s to 60s whose cheeks, jowls or brows have started to drop, or who have a softer jawline and some looseness under the chin. It is less helpful when the main concern is crepey texture rather than sagging (radiofrequency treatments such as Thermage FLX often suit that better), or when the face is very thin and hollow, in which case restoring volume may matter more than tightening. How much does Ultherapy cost in Busan? Ultherapy is priced by the number of lines (shots). Around 300 lines is typical for targeted areas such as the jawline and lower cheeks, while around 600 lines allows fuller coverage of the face and under the chin. In Busan, Ultherapy is often sold as a package combined with a skin booster or skin Botox. Ultherapy 300 lines + full-face skin Botox : from KRW 790,000 Ultherapy 600 lines + full-face skin Botox : from KRW 1,690,000 Prices checked October 2026. Korean clinic prices for cosmetic treatments are quoted in won and exclude 10% VAT, which is added at payment. Prices can change, so always confirm the current price when you book. When comparing quotes, check the number of lines included, whether the device is genuine Ultherapy or Ultherapy PRIME rather than a different HIFU machine, what is bundled in the package, and whether VAT is included in the figure you were given. What happens during a session Consultation. The doctor assesses sagging, fat and skin thickness, then plans the areas, depths and number of lines. Numbing. Numbing cream is applied for about 30 minutes, then the skin is cleansed and a gel is applied for the imaging probe. Treatment. The transducer shows the skin layers on screen and delivers focused ultrasound over about 30–60 minutes. Areas close to bone, such as the jawline, can feel prickly or warm. Straight back to your day. Mild redness is common and usually fades within hours. Results: what to expect and when Right after treatment: some people notice slight tightening; mild redness is normal. Months 2–3: lifting and firmness become visible as collagen renews. Months 3–6: results usually reach their peak. Months 6–12: the effect gradually fades with natural ageing; a repeat session maintains it. Results and timing vary from person to person. Even, well-planned coverage matters more for a natural result than simply using the maximum number of lines. Recovery, side effects and aftercare Ultherapy has very little downtime. The most common effects are redness or mild swelling that settles within hours to a few days, and tenderness or a bruised feeling along the jaw that can last a few days. Rarely, people experience temporary numbness, small bruises, welts or nerve irritation. Aftercare tips On the day of treatment, avoid saunas and jjimjilbang, hot baths, alcohol and strenuous exercise. Use sunscreen carefully for 1–2 weeks and avoid rubbing or scratching the treated area. Keep the skin well moisturised; makeup can usually be applied once the skin has calmed. Who should wait or avoid it Ultherapy is not recommended during pregnancy, over an active skin infection, open wound or severe acne in the area, or near metal implants or a pacemaker. Tell your doctor about any recent fillers, threads or other procedures in the area. Planning Ultherapy around a trip to Busan Because there is no real downtime, Ultherapy fits easily into a short stay. You can usually go sightseeing the same afternoon, and flying is generally fine, although jaw tenderness can feel more noticeable when chewing on the plane. Booking the treatment early in your trip gives you a few days to settle before you fly home. Share your flight date at the consultation so the plan fits your schedule. Ultherapy vs other lifting options Ultherapy : Focused ultrasound with real-time imaging. Best for: sagging cheeks, jowls and brows. Ultherapy PRIME : Newer Ultherapy platform with upgraded imaging. Best for: the same goals on the latest hardware. Thermage FLX : Monopolar radiofrequency heating the deep dermis. Best for: crepey skin and overall firmness. Shurink Universe : HIFU at set depths, without imaging. Best for: jawline and budget-friendly maintenance. In short, choose Ultherapy for an imaging-guided lift of deeper sagging, Thermage FLX when skin texture is the bigger concern, and Shurink Universe for more frequent, lower-cost upkeep between sessions. Frequently asked questions Does Ultherapy hurt? Most people describe it as warm, prickly pulses, strongest over bony areas. Numbing cream is applied beforehand to keep it comfortable. How many sessions will I need? One session is usually enough for a visible change. Many people repeat it every 6–12 months to maintain the result. Is 300 or 600 lines right for me? 300 lines generally focuses on priority areas such as the jawline and lower cheeks, while 600 lines covers the full face and under the chin more thoroughly. The right number depends on your degree of sagging and the areas you want treated. Thinking about Ultherapy in Busan?
