✅ What the treatment is

• “Jaw Botox” (also known as masseter-muscle Botox) is a non-surgical injection of a neuromodulator into the masseter muscles (the chewing muscles on the sides of the jaw) to reduce muscle size and create a more slender, V-shaped lower face.
• It is popular in Korea for facial contouring — softening a wide or square jawline without surgery.
• The procedure time is short (often 10-20 minutes) and recovery is minimal.

⚙️ How the procedure typically works

1. Consultation: The practitioner assesses your jaw muscle size, face shape, bite, and whether the wide jaw is primarily due to muscle hypertrophy (rather than bone structure).
2. Injection: Neuromodulator is injected into both masseter muscles. The dose varies depending on muscle size and goal.
3. Recovery: Little to no downtime; you can usually return to normal activities right away. Some mild swelling or tenderness may occur for a day or two.
4. Results timeline:

• Initial effect: ~2–3 weeks after treatment.
• Peak slimming effect: ~2–3 months.
• Duration: Typically 4–6 months, though results may last longer with repeat treatments and muscle adaptation.

1. Maintenance: To maintain the result, repeat sessions are often recommended every 4–6 months (or longer once muscle size diminishes).

💰 Typical cost range in Seoul

• The cost depends on clinic location, brand of neuromodulator, muscle size, and dosage.
• As a rough guideline: around ₩100,000 to ₩300,000 KRW per session is common in Seoul.
• Some clinics report lower starting prices (for smaller doses or local brands) and higher for premium brands or larger muscles.
• Always check exactly what is included (consultation, number of units, follow-up).

🧐 What to ask / check before you go ahead

• Which brand of neuromodulator will be used (domestic vs imported) and its authenticity.
• How many units/mL or what dose is planned for your masseter muscles.
• The injector’s experience with masseter/injectable contouring and lower face anatomy.
• Whether your wide jaw is due to muscle, bone, fat or a combination — because if it’s bone, Botox alone may not give the desired result.
• Realistic expectations: the change is contouring/slimming, not drastic jaw-bone reduction.
• After-care instructions: what you should avoid (chewing hard foods, excessive jaw motion, etc.) in the first 24-48 hours.
• Maintenance plan & cost for touch-ups.
• Clear pricing: so you know what you're paying for and for how many units.
• Language support and any travel-patient logistics (if you’re visiting from abroad).

📋 Smart tips & after-treatment care

• After the injection: avoid chewing gum, hard/chewy foods for at least 1-2 days so the muscle can settle.
• Minimise large jaw movements or clenching for a few days (especially if you grind your teeth or clench at night).
• You can return to most daily activities immediately, but avoid heavy exercise or sauna for the first 24 hours if recommended by the clinic.
• Monitor your jaw when biting/chewing over the next few weeks — you should notice gradual slimming.
• If you are a habitual teeth-grinder or have TMJ/jaw-clenching issues, consider discussing with your provider, because addressing the habit enhances long-term results.
• After a few months, when you see the effect fading, schedule your next session if you want to maintain the contour.
