Jaw (Masseter) Botox in Gangnam, Seoul

Quick answer: Jaw Botox relaxes an enlarged masseter (chewing) muscle so it gradually shrinks, narrowing a square lower face into a softer V-line. It can also ease clenching and grinding. At AMRED Clinic in Cheongdam, Gangnam it is injected under ultrasound guidance (See Through™), so dose matches real muscle thickness; slimming shows over four to six weeks.

Why the lower face looks wide

A strong masseter, often from clenching or chewing habits, adds width at the jaw angle. Relaxing it lets the muscle reduce in bulk, which can look like a narrower, more oval face.

Why ultrasound helps

Masseter thickness and position vary; injecting too shallow or near the smile muscles can cause an uneven smile. Ultrasound shows exactly where the bulk is.
