Jaw Slimming Botox in Seoul

QUICK ANSWER

Jaw slimming Botox relaxes an enlarged masseter muscle to soften a square jawline and can ease teeth clenching. The injection takes about 10 minutes with no downtime. Slimming becomes visible after 2–4 weeks, peaks around 6–8 weeks and lasts 4–6 months; repeated sessions can extend it.

How it works

The masseter is the chewing muscle at the angle of the jaw. When it is bulky, the lower face looks wide. Relaxing it lets the muscle shrink, giving a slimmer, more oval contour.

Who is it for?

  • Square jaw from muscle bulk rather than bone
  • Teeth clenching or grinding

Aftercare

  • Avoid hard or chewy food for a few days
  • No facial massage for 1 week
