Smile Line Treatment in Korea: Fillers and Other Options

October 25, 2026

“Smile lines” usually means the nasolabial folds, the creases running from the sides of the nose to the corners of the mouth (some people also use the term for crow’s feet around the eyes). In Korea there are several ways to soften them, and filler is only one. Because these lines have more than one cause, the best result often comes from choosing the right tool, or combination, for your face. This guide compares the main options available in Busan, what they cost and how they fit into a trip.

Quick answer: Hyaluronic acid filler is the quickest way to soften smile lines that stay visible at rest, with results lasting about 6–12 months. When cheek sagging drives the fold, thread lifts or lifting devices such as Ultherapy often work better or alongside filler. Radiesse adds volume and stimulates collagen, and restoring mid-face volume can soften folds indirectly. In Seomyeon, options start from KRW 149,000 for filler beside the nose and KRW 190,000 for a filler, Botox and mono-thread package, before 10% VAT.

What causes smile lines?

Everyone has some fold between the cheek and the mouth; it is part of a natural smile. It becomes more pronounced through a mix of:

  • Volume loss in the mid-face and beside the nose.
  • Sagging , as the cheek tissue descends and gathers over the fold.
  • Skin changes : less collagen and elasticity, often accelerated by sun exposure and smoking.
  • Movement : thousands of smiles and conversations every day.

A quick self-check: lie back and look in a handheld mirror. If the fold softens a lot, sagging is a major factor. If it stays deep, volume loss and skin creasing matter more.

Option 1: hyaluronic acid filler

HA filler is placed beneath the fold to lift it from below. It works straight away, takes about 10–20 minutes after numbing cream and can be dissolved if needed. It suits folds that remain visible when your face is still. The creases right beside the nose need a softer, more precise placement. The main limitation is that filling a fold caused by sagging can look heavy, so amounts should stay modest.

  • Filler for creases beside the nose : from KRW 149,000
  • Nasolabial fold filler 2cc + nasolabial fold Botox + 10 MINT mono threads : from KRW 190,000

Option 2: Radiesse (calcium hydroxylapatite)

Radiesse is a filler made of calcium hydroxylapatite microspheres in a gel. It adds volume immediately and stimulates collagen over the following months. It is used for nasolabial folds and mouth-corner lines and tends to last longer than many HA fillers. The trade-off is that it cannot be dissolved with hyaluronidase, so it is placed conservatively.

  • Radiesse 1 syringe, 1 session : from KRW 590,000

Option 3: thread lifts

Dissolvable cog threads such as MINT threads have small barbs that grip and lift sagging tissue in the cheeks, while collagen forms around them. Lifting the cheek can make the fold look shallower without adding much filler. Expect 2–3 days of tightness and swelling, and 1–2 weeks of avoiding wide mouth opening and hard foods.

  • Nasolabial fold mini lift: 4 MINT mono + 4 JAMBER threads + filler 2cc : from KRW 590,000

Option 4: energy-based lifting

HIFU and radiofrequency devices tighten deeper layers without needles or entry points. They suit people with early sagging who want gradual improvement and no downtime. Results build over 2–6 months. In Seomyeon, examples include Ultherapy 300 shots with full-face skin Botox from KRW 790,000 and ONDA 60,000 J with Shurink Universe 300 shots from KRW 429,000.

Option 5: restoring mid-face volume

Sometimes the most natural way to soften a smile line is to treat the cheek above it. Restoring flattened mid-face volume with HA filler or a gradual collagen stimulator such as Juvelook Volume can support the area and make the fold look less deep. Doctors often start here before filling the fold directly.

And if you mean crow’s feet?

The lines at the outer corners of the eyes when you smile are movement lines, and they respond best to Botox, which relaxes the muscle around the eye. Fine crepey lines there may also benefit from a skin booster.

Which option should you choose?

  • Fold deep at rest, little sagging : HA filler.
  • Fold plus visible cheek sagging : threads, often with a small amount of filler.
  • Early laxity, no needles wanted : HIFU or radiofrequency lifting.
  • Longer-lasting volume and collagen : Radiesse, placed conservatively.
  • Flat mid-face : cheek volume first, then reassess the fold.

Recovery and planning around a trip

Filler and energy devices fit easily into a short stay: you can sightsee the same day. Threads need a gentler few days with soft food. Heat-based devices are usually not done over fresh threads, so if you want both, the order and gap need planning; on a short trip, one treatment now and another on a later visit is often simplest. For any filler, avoid saunas, jjimjilbang, alcohol and hard exercise on the day, and seek urgent care for severe pain, skin colour change or vision change.

Frequently asked questions

Can smile lines be removed completely?

Not naturally. Some fold is part of a normal smile, and erasing it usually looks overfilled. The aim is to soften it.

Which lasts longest?

Radiesse and lifting devices often last longer than HA filler in this mobile area, but results vary with age, skin and lifestyle.

Can I combine filler and threads in one visit?

Yes, several packages do exactly that. The doctor decides the amounts once sagging and volume loss have been assessed.

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?
