Korean Face Slimming Injections in Busan: What to Expect

October 25, 2026

“Face slimming injections” are a staple of Korean clinics, promising a smaller, V-shaped face without surgery. The name actually covers two quite different treatments: fat-dissolving contour injections, and Botox that slims the jaw muscle. Knowing which one targets your concern is the key to a good result, and to planning realistically around a trip to Busan. This guide explains how each works, what the evidence does and does not show, the costs in Seomyeon and what to expect.

Quick answer: Korean face slimming usually means either a fat-dissolving contour injection placed into soft fat in the cheeks, jowls or under the chin, or Botox injected into the masseter muscle to slim a square jaw. Contour injections take about 5–10 minutes with no downtime but usually need 3–5 sessions, 1–2 weeks apart. Jaw Botox works in a single session, with slimming visible after 4–8 weeks. Many people need both. In Seomyeon, combined packages start from KRW 99,000 and Shine Cut full-face contouring from KRW 290,000, before 10% VAT.

Two causes of a wide face, two different injections

A face can look wide or round because of soft fat, a strong chewing muscle, bone structure, sagging skin or a mix. Injections can help the first two:

  • Fat: soft fullness in the cheeks, along the jaw or under the chin. Targeted by fat-dissolving contour injections.
  • Muscle: a firm bulge at the angle of the jaw when you clench. Targeted by jaw (masseter) Botox.

Injections cannot change bone, and slimming a face with loose skin can make sagging look more obvious, so lifting may be the better first step for some people.

Fat-dissolving contour injections

These lipolytic injections are placed into the fat layer with a fine needle. The solution acts on fat cells, and the body gradually clears the treated fat over the following weeks. Some formulations also aim to reduce puffiness. Clinics in Korea often use their own named formulas; in Seomyeon these include Facial Contouring Injection, Power Contouring Injection and Shine Cut Injection, in set volumes such as 12cc for one area or 24cc for the full face.

What the evidence says

Fat-dissolving injections based on deoxycholic acid have regulatory approval in some countries for fat under the chin. Many clinic contour formulas, however, are blends whose exact ingredients differ, and they have far less published evidence behind them. Results are usually modest and gradual, vary considerably between people and depend on keeping a stable weight. Ask at your consultation what is in the product used for you, and treat any “dramatic” promises with caution.

Jaw Botox for a square jaw

Botulinum toxin injected into the masseter relaxes the chewing muscle, which gradually shrinks in bulk over 4–8 weeks. This is a well-established use with a long track record. One session typically lasts around 4–6 months, and many people find the effect lasts longer after repeat treatments. A small-face plan can also include the temporalis muscle at the side of the head and the parotid area at the jaw angle.

How much do face slimming injections cost in Busan?

  • Jaw Botox + Power Contouring Injection 18cc : from KRW 99,000
  • Small-face contouring injection: temporalis, parotid glands and jaw angles : from KRW 149,000
  • Shine Cut Injection, 1 area (12cc) : from KRW 190,000
  • Shine Cut Injection, full face (24cc) : from KRW 290,000

Remember that contour injections are a course, so budget for several sessions. Prices checked October 2026; they exclude 10% VAT, are paid in won at the clinic, and prices can change, so confirm on WhatsApp.

What happens at a session

  1. Message ahead. Send front and side photos, say which areas look full and how long you are staying.
  2. Consultation. The doctor checks fat thickness, muscle bulk (feeling the jaw while you clench) and skin elasticity, then chooses the formula, volume and zones.
  3. Treatment. No numbing is usually needed. Injections take about 5–10 minutes, with brief stinging or pressure.
  4. Back to your day. No downtime; the next contour session is planned 1–2 weeks later.

Results timeline

  • After each contour session: mild swelling for a day or two.
  • After 2–3 sessions: gradual slimming may become noticeable.
  • A few weeks after the last session: the result can be assessed.
  • Jaw Botox: slimming develops over 4–8 weeks after one session.

Side effects and aftercare

Contour injections commonly cause swelling, redness, tenderness or bruising, plus temporary firmness, itching or small lumps that soften over several days. Rarely, results are uneven or the skin is irritated. Jaw Botox can cause chewing fatigue for a few weeks and, rarely, a temporarily uneven smile.

  • For 3–4 hours, do not lie down or rub the treated area.
  • On the day, avoid saunas, jjimjilbang, hot baths, hard exercise and alcohol.
  • Do not massage or press firmly on the treated area.

Planning a course around your trip

This is the main practical challenge for visitors. A single contour session rarely gives a visible change, so you need either a stay of a few weeks (for example, sessions on days 1, 8 and 15) or repeat visits to Korea. Jaw Botox is much easier: one session, then the result develops at home. If your schedule is tight, ask on WhatsApp before booking; a single-session device such as ONDA, or jaw Botox alone, may suit you better.

Frequently asked questions

Does fat come back after contour injections?

Treated fat cells are cleared, but remaining fat cells can still grow. Weight gain can bring fullness back, so a stable weight matters most.

Which do I need, contour injection or jaw Botox?

Clench your teeth: if a firm bulge appears at the jaw angle, muscle is involved. Soft fullness elsewhere points to fat. Many people have both.

Can I slim my face in one visit?

Jaw Botox is one visit, though results take weeks. Fat-dissolving injections need a course of sessions.

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?
