What is Masseter Botox, and is it right for you?
Masseter Botox relaxes the chewing muscle at the angle of the jaw. Over weeks the muscle shrinks, so a square lower face looks slimmer and more V-shaped; it can also ease teeth clenching.
At YAAN Clinic in Gangnam, Seoul, jaw Botox is ₩170,000 with Xeomin or ₩350,000 with Allergan. Slimming shows over 4–6 weeks and lasts about 4–6 months.
Who Masseter Botox suits, and who it doesn't
We would rather tell you what you don't need. These are general guides; your doctor confirms suitability after examining you.
Often a good fit
- A wide jaw from a bulky masseter
- Teeth clenching or grinding
- A square lower face
- People wanting a V-line without surgery
- Repeat patients maintaining results
Probably not the first choice
- Width from fat or bone, not muscle
- Very thin faces where cheeks may hollow
- Neuromuscular disorders such as myasthenia gravis
- Pregnancy or breastfeeding
How it works
Check the cause: the doctor feels the muscle while you clench.
Dose: units per side depend on muscle size.
Timeline: slimming shows at 4–6 weeks. Compare with InMode for fat.
