What is masseter treatment?
A wide or square jaw can be partly shaped by strong masseter muscles. Botox® relaxes these muscles over time, which can slim the lower face for patients where muscle bulk—not bone—is the main factor.
How it works
Small injections are placed into the masseter. The muscle gradually softens; chewing usually stays comfortable at normal meals. Full changes evolve over several weeks.
Benefits
No surgery; gradual, natural-looking change for suitable candidates. Effects often last longer than typical upper-face Botox® because muscle volume changes slowly.

Often 6–12 months, sometimes longer, depending on muscle strength and dose.
Will I chew normally?
We aim to reduce excess bulk, not normal function. Tell us if anything feels off—we adjust.

Early changes in a few weeks; maximum slimming often around 2–3 months.
