Face Slimming Injections in Korea

Eugene Lee • November 10, 2025

What Are Face Slimming Injections?

  • Face slimming injections refer primarily to non-surgical injectable treatments aimed at reducing the width or “bulk” of the lower face, especially around the jawline and masseter muscles.
  • In Korea, the most common approach is injections of a neurotoxin (such as Botulinum toxin type A) into the masseter muscles to reduce their size over time and thus create a slimmer lower-face or “V-line” appearance.
  • These injections may be combined with other treatments (fat-dissolving injections, fillers, skin-tightening) depending on your anatomy and goals.

Who Is a Good Candidate?

  • Someone with a wide or square-looking jawline caused by overdeveloped masseter muscles (often due to genetics, grinding/clenching, or chewing habits).
  • Someone who wants a non-surgical solution to refine their lower-face contour, avoid downtime, and create a softer look.
  • Someone whose facial width issue is primarily soft-tissue (muscle or fat) rather than bone structure (if the jaw bone width is large then injections alone may give limited results).
  • Someone who has realistic expectations: understands results are subtle to moderate, not permanent (unless maintained) and will need follow-up treatments.

Treatment Menu: What You Can Offer / Explain

  • Masseter Neurotoxin Injection (Jaw Slimming Botox)
  • Targets: Large/wide masseter muscles at the jaw angle
  • Mechanism: Neurotoxin relaxes the muscle → muscle size gradually reduces → jaw looks slimmer
  • Benefits: Quick procedure, minimal downtime, dual benefit of slimming + relief from jaw-clenching or TMJ symptoms in many cases. gangnamskinclinic.com+1
  • Fat-Dissolving or Contour Injections for Lower Face
  • Targets: Excess fatty tissue under the chin or along the jawline making the face look broader or heavier
  • Mechanism: Injection of lipolytic solution or combined treatment to reduce fat volume and enhance jawline definition. Renovo Skin Clinic
  • Combined Approach for Face Slimming & V-Line Appearance
  • For best results, especially if you have both muscle bulk and soft-tissue/fat concerns, combining neurotoxin + fat-dissolving + filler or skin tightening may deliver a more balanced sculpting effect.
  • This can create the styled “V-line” look popular in Korea: a narrower lower face and defined chin/jawline.

What to Expect & Aftercare

  • Procedure Time: The neurotoxin injection alone often takes about 15-30 minutes.
  • Downtime: Very minimal. Mild swelling, bruise possible. Many patients return to normal activities immediately.
  • Results Timeline:
  • For neurotoxin: Visible changes usually begin in 2-4 weeks as muscle shrinks.
  • For fat-dissolving: Effects gradually appear as fat is metabolized—may take weeks.
  • Longevity:
  • Neurotoxin results typically last ~3-6 months; after repeat treatments the interval may extend.
  • Maintenance is key: without follow-up the muscle may gradually regain size; fat reduction may also require sessions for optimal contour.
  • Aftercare Tips:
  • Avoid heavy chewing, gum, or clenching for the first few days if masseter was treated.
  • Avoid pressing/massage in the injection area unless recommended.
  • Follow any specific instructions from your clinician (avoid sauna/hot baths if advised).
  • Monitor for any asymmetry or prolonged swelling and contact your clinic if needed.

Typical Cost Range in Korea

  • The cost for jaw-slimming injections in Korea varies based on clinic, brand of neurotoxin, dose, combination treatments, location, etc.
  • Indicative cost for masseter neurotoxin injections: from roughly โ‚ฉ 100,000 to โ‚ฉ 300,000 (≈ US$80-$230) per session in Seoul clinics.
  • Combined treatments or premium clinics may cost more; you should encourage clients to ask about detailed breakdown (units, brand, follow-up).

Why Choose Korea for Face Slimming Injections

  • Korea (especially Seoul) is globally recognised for advanced aesthetic treatments, including lower-face contouring. Clinics have high volume experience in masseter/jaw treatment.
  • Aesthetic culture emphasises the “V-line” or slim lower face, driving strong skill and innovation in treatments for jaw slimming.
  • Many clinics offer international patient services, English-speaking support, and transparent consultation processes when welcoming overseas visitors.
  • Non-surgical approaches are widely accepted and refined in Korea, making injections for face slimming both accessible and sophisticated.

Limitations & Things to Consider

  • If your jaw width is primarily caused by bone structure (wide mandibular angle) rather than muscle or fat, injections alone may not achieve the desired slimming. Surgery may be required.
  • Results are not permanent: maintenance sessions are needed. Patients must understand this from the start.
  • Over-treatment or inappropriate dose may lead to complications such as jaw weakness, chewing difficulties, or asymmetry. Always choose a qualified specialist.
  • Understand the clinic’s policy: how many sessions are included, whether follow-up is part of the cost, what happens in case of suboptimal result.

How to Fix Overfilled Under-Eye Fillers in Korea Under-eye fillers can brighten dark circles and smooth hollow tear troughs—but when the area becomes overfilled, swollen, or unnaturally puffy, it can make you look more tired rather than refreshed. Korea is one of the top destinations for filler correction, especially for delicate under-eye issues where precision is crucial. If your under-eye fillers look heavy, lumpy, or “pillowy,” here’s exactly how Korean dermatologists typically fix them. Why Under-Eye Fillers Get Overfilled The under-eye area is extremely thin and prone to complications. Overfilling can happen due to: Too much filler placed too superficially Wrong type of filler used (too thick or water-attracting) Old filler buildup from past injections Migration from the mid-cheek Natural swelling exaggerated by HA fillers Improper injection depth or technique The result often appears as puffiness, swelling, shadowing, or a “pillow face” look. How Korea Fixes Overfilled Under-Eye Fillers Korean dermatology focuses on natural, subtle, and precise correction. The goal isn’t just to flatten the area—it’s to restore a smooth, youthful under-eye contour while maintaining natural expression. 1. Hyaluronidase (Filler Dissolving) for Immediate Puffiness Relief The fastest way to correct overfilling is with hyaluronidase, an enzyme that dissolves unwanted hyaluronic acid filler. Why Koreans use this method first: Works within minutes Targets only the migrated or swollen areas Reduces heaviness and shadowing Makes space for better, more natural correction later Most patients see improvement the same day. 2. Precise Dissolving for the Tear Trough (Not the Entire Area) Instead of fully dissolving everything, Korean specialists often treat: The bulge created by excess filler The superficial “lumpy” areas The migration zone near the lower eyelid Why this matters: The tear trough area is thin, so the goal is precision, not complete removal unless necessary. 3. Re-Filling the Right Way (If Needed) Many patients choose to re-fill the area—but only after a full reset. Korean dermatologists avoid placing filler directly under the eye unless absolutely needed. Instead, they support the area using: Mid-cheek lifting points Deep medial cheek augmentation Under-eye structural support instead of surface filler This prevents the puffy look and creates a smooth, subtle lift. 4. Non-Surgical Lifting Devices for Under-Eye Tightening If swelling or heaviness has stretched the skin, lifting devices help refine the under-eye contour: HIFU (Shurink, Liftera) for tightening Ultherapy for deeper lifting RF tightening for fine wrinkling Benefits: Reduces sagging that exaggerates bags Helps under-eye contours look smoother Minimizes future filler migration 5. Skin Boosters for Texture, Not Volume After dissolving, some patients don’t actually need more filler. Instead, Korean clinics often use lightweight skin boosters to brighten and firm: Rejuran Exosomes Light HA boosters Collagen-stimulating micro-lifting These improve the under-eye without adding bulk. Signs Your Under-Eye Filler Needs Correction You may need dissolving if you notice: Puffiness that doesn’t go away Bulging or swelling under the eyes Tyndall effect (blue tint under the skin) Filler lumps or ridges Under-eye looks worse in certain lighting Filler that migrated downward toward the cheeks A tired or “overdone” look These issues are extremely common—and very fixable in Korea. Recovery Timeline in Korea Dissolving session: 5–10 minutes Swelling reduction: Within hours Final flattening: 2–3 days Re-filling (optional): After 7–14 days Skin boosters/lifting: Same day or staggered depending on plan Most patients return to daily life immediately. Why Fixing Under-Eye Fillers in Korea Is So Effective Korean dermatology is known for: Natural aesthetic philosophy Ultra-precise dissolving techniques Understanding of international skin types Use of multiple methods beyond filler alone Customized under-eye plans (not “one filler fits all”) Skillful lower-eyelid anatomy management This makes Korea one of the safest places for under-eye filler correction. Final Thoughts Overfilled under-eye fillers can make you look swollen, older, or constantly tired—but Korean clinics specialize in restoring a smooth, refreshed, and natural look. With a combination of dissolving, structural rebalancing, and subtle skin-tightening treatments, the under-eye area can be corrected quickly and beautifully.
