Jaw (Masseter) Botox in Myeongdong
Jaw Botox relaxes the masseter muscle at the angle of the jaw. As the muscle shrinks over 2–4 weeks, the lower face looks slimmer and more V-shaped, and teeth clenching often eases. At Val:U Clinic it starts from KRW 33,000.

What it treats
Who Jaw (Masseter) Botox is for
- Square or wide jaw from muscle
- Jaw clenching and grinding
- V-line contouring
How it works
The science, simply
Injections are placed into the thickest part of the masseter. The muscle works less and gradually reduces in size, which narrows the lower face.
If the width comes from fat or bone rather than muscle, your doctor may suggest contouring injections or HIFU instead.
Your visit, step by step
