Jawline slimming – or masseters reduction for cosmetic purposes – is a simple yet effective procedure that involves the injection of the neurotoxin botulinum type A into the large masseter muscles to create a slim and more feminine jawline.

Masseter muscle reduction is great for patients with Bruxism, ie excessive grinding of the teeth or clenching of the jaw. Treatment of bruxism may improve the symptoms, which include hypersensitivity of the teeth, headaches, aching jaw muscles. Treatment with muscle relaxing injections will also improve the appearance of the hypertrophied or enlarged jaw muscles, which can make a face look too square.

Masseter reduction is also good for those who want a more contoured look, or those who have a face that they feel is too square or round. They want a slimmer and more petite face.
