Masseter Jaw Slimming
A softer, slimmer lower face. Naturally contoured.
Overview
An enlarged masseter can give the lower face a square, heavy contour that feels out of balance with the rest of the face. A precise, doctor-led botulinum toxin treatment gently relaxes and reduces the muscle, gradually softening and slimming the jawline for a more harmonious, refined profile.
The masseter is the strong muscle at the angle of the jaw, responsible for closing the jaw during chewing. In some people it is naturally powerful; in others it grows enlarged through habitual clenching or grinding. Either way, a bulky masseter creates a broad, square lower face that can feel disproportionate to the upper face. Treatment uses a purified protein, the same used in anti-wrinkle therapy, injected precisely into the masseter to quiet and gradually reduce the muscle. Over several weeks the muscle softens and reduces in size, and the lower face takes on a gentler, slimmer, more heart shaped contour. Because the change is gradual and the muscle is your own tissue simply relaxing, the result reads as natural rather than treated. At Luminè, every plan is doctor led and begins with an honest assessment of your masseter, your facial proportions and whether jaw slimming, grinding relief, or both, is the right goal for you.

Why Luminè
Jaw slimming is as much about proportion as it is about the muscle itself. As doctors, we assess the true cause of a heavy jaw, whether it is the masseter, bone structure, fat, or a combination, before recommending treatment. We plan the dose conservatively so the change is graceful rather than abrupt, and we will tell you honestly whether masseter treatment will give you the contour you are hoping for.
Questions
Frequently Asked
How is jaw slimming different from teeth grinding treatment?
They use the same treatment, botulinum toxin into the masseter, but the goal differs. Teeth grinding treatment focuses on relieving clenching symptoms and protecting the teeth, while jaw slimming focuses on reducing the size of the muscle for a softer facial contour. Many patients benefit from both.
How long until I see a slimmer jaw?
The muscle begins to soften within two to four weeks, with the visible slimming developing gradually over six to twelve weeks as the muscle reduces in size.
Will it affect my chewing?
At the doses used for slimming, chewing is rarely affected. Some patients notice a minor change in the strength of their bite, which resolves as the treatment wears off.
Does it hurt?
Discomfort is minimal and brief, using very fine needles. No anaesthetic is usually required.
How long does it last?
Typically three to six months. With repeated treatment the masseter can become less overactive over time, and some patients find they can extend the interval between sessions.
Is the result permanent?
No. The effect is reversible and gradually wears off as the muscle activity returns. Maintenance treatments sustain the contour.
Is it safe?
When administered by a qualified doctor after proper assessment, masseter treatment has a well established safety profile. Potential side effects are discussed fully at your consultation.
