Face Slimming Injections in Korea

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 ₩ 100,000 to ₩ 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.
