Masseter Botox in Korea, Seoul
Gangnam ONLIF Clinic
ONLIF Clinic Gangnam, Seoul | Global Experts in Masseter Botox
What Masseter Botox Is
Masseter Botox is a cosmetic injection that uses botulinum toxin to relax the masseter muscles — the large chewing muscles at the back of your jaw. When these muscles are overactive or bulky, they can make the lower face look wide or square. Reducing their activity with Botox can lead to a softer, slimmer lower-face contour over time.
How It Works
- Targeted injections: Botox is placed into specific points in the masseter muscles on each side of the face.
- Muscle relaxation: The treatment reduces the strength of muscle contractions.
- Gradual slimming: As the muscle becomes less active, its size can decrease, softening the jawline.
This effect is gradual and temporary, and repeat sessions help maintain the shape you want.
What to Expect
Consultation
Before treatment, you should have a proper consultation where:
- Your facial structure and muscle activity are assessed
- Your goals are discussed and realistic expectations are set
- The injector explains how many units will be used
- You have time to ask questions
Procedure
- Quick: Usually about 10–20 minutes
- Comfortable: Small injections into the jaw muscles
- Minimal downtime: Most people return to normal activities immediately
Results & Timeline
- Initial change: Some muscle softening within a few days
- Visible slimming: Noticeable over several weeks
- Full effect: Around 6–8 weeks
- Duration: Typically 3–6 months, depending on muscle strength and dosing
Maintenance treatments are common to sustain results.
Benefits
✔ Helps
soften a wide or square jawline due to muscle bulk
✔ Non-surgical and minimally invasive
✔ Quick procedure with little to no downtime
✔ Natural-looking contouring when done well
Who It’s Best For
This treatment is a good fit if you:
- Have a wide lower face largely due to prominent masseter muscles
- Want a non-surgical contouring option
- Prefer gradual, natural-looking slimming
- Are willing to have periodic follow-ups to maintain the effect
It’s not usually effective for jaw width caused primarily by bone structure — that requires different approaches.
Aftercare Tips
To help ensure a smooth result:
✅ Avoid touching, rubbing, or applying pressure to the jaw area for about
24 hours
✅ Stay upright for a few hours after treatment
✅ Avoid intense exercise or hot environments (like saunas) on treatment day
✅ Follow any specific aftercare instructions from your provider
Questions to Ask Before Booking
You can ask clinics:
- Do you provide Botox specifically for masseter (jaw slimming)?
- How many units do you recommend for my jaw type?
- What results can I realistically expect and in what timeframe?
- Can the consultation and aftercare information be provided in English (or your language)?
- What follow-up or support do you offer after the treatment?
These help ensure you’re comfortable with the plan and communication.
