Curious about Masseter Botox and its transformative effects? This guide explains the treatment process, expected results, benefits, and safety measures. If you want to slim your jawline, ease jaw tension, or reduce teeth grinding (bruxism), Masseter Botox can help. It can give you a natural and refreshed look.
What Is Masseter Botox?
Masseter Botox is an aesthetic procedure that involves the injection of botulinum toxin into the masseter muscles of your jaw.
These work to slightly weaken the masseter muscles, giving the impression of a slimmer and better-defined jawline, while it may also alleviate symptoms such as bruxism or chronic tension of the jaw. This is a non-invasive treatment characterized by natural and effective results, which develop gradually over time.

How Does Masseter Botox Work?
During the treatment, the practitioner will be administering the botulinum toxin in small, controlled doses into the masseter muscles. As it works on blocking nerve communications responsible for muscular contractions, these muscles take their time to relax and shrink down over time. This selective treatment spares every other muscle action, retaining natural facial features by subtly accentuating the jawlines.
How long does Masseter Botox last?
For most people, results from a treatment generally last anywhere from 3 to 6 months. The length of time depends on the strength of the muscle, how your body metabolizes the neurotoxin, and dosage used. Many practitioners recommend follow-up treatments every few months to maintain consistent results.
How Long Does It Take to See Results?
Masseter Botox does not happen overnight. Generally, patients start noticing an improvement after one to two weeks. Until the third or fourth week, full effects start to appear. Such a gradual change helps your system adapt naturally to the new contours of your face, thus reducing any initial discomfort you may have while getting used to them.
Does Masseter Botox Cause Jowls?
Performed by the expert doctor in Thérapie Clinic, Masseter Botox specifically relaxes the masseter muscles while leaving all the surrounding tissues unharmed. This helps one achieve natural balance and makes no compromise with facial structure. Further, with treating the jawline, symptoms related to grinding of teeth, called bruxism, are treated along with relief from tensions at the jaws-all this is attained without developing the risk for sagging and formation of jowls.

Masseter Botox is ideal for those who:
Want a Slimmer Jawline: Perfect to thin out a chunky jaw to provide a better angle and definition.
Have Jaw Tension or Bruxism: Relieves pain related to an overactive jaw muscle.
