Square Jaw Slimming Without Surgery in Gangnam, Seoul

Quick answer: A square jaw is often caused by a large masseter (chewing) muscle rather than bone. Jaw Botox relaxes the muscle so it gradually shrinks, softening the lower face into a V-shape over four to six weeks. AMRED Clinic in Cheongdam, Gangnam uses ultrasound to measure the muscle and dose precisely; bony width requires surgery.
