What is Jawline Slimmer?

Jawline slimming injections is one of the most popular treatments at our clinic. Slimming the masseter muscles makes a square jaw or square face look more slim, oval or heart shaped. The patient’s face is slimmed going from a more masculine square shape to a lovely heart shape.

Jawline slimming injections take about 2 to 4 weeks to work as it takes time for the muscle to relax and reduce in size. The maximal effect will be about 8 weeks after the treatment.


Jawline Slimmer Treatment is great for patients with excessive grinding of the teeth or clenching of the jaw. The treatment 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.

Jawline Slimmer 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.

No unsightly scar no scalpel or stitches involved.
