- Doctor-led Masseter Botox treatments by medical professionals
- Reduces jaw muscle activity for a slimmer, balanced lower face
Masseter Botox is a targeted treatment used to relax the masseter muscles, which are located at the sides of the jaw and play an important role in chewing. When these muscles are particularly prominent, they can contribute to a wider or more square-shaped lower face. Botox treatment can be carefully administered into the masseters to reduce muscle activity and gradually create a softer, more refined jawline while maintaining natural facial movement.
At Dr Nyla Medispa in Mayfair, London, Masseter Botox treatments are performed within a medically regulated setting under the guidance of Dr Nyla Raja and her experienced medical team. Every treatment plan begins with a detailed assessment of your facial anatomy, masseter muscle activity, and lower-face proportions to ensure a precise, personalised approach.

Masseter Botox FAQs
-
What Is Masseter Botox and How Does It Work?
-
Masseter Botox involves carefully placed injections of botulinum toxin type A into the masseter muscles, which are located at the sides of the jaw and play an important role in chewing and clenching.
By temporarily reducing activity within these muscles, treatment can gradually reduce masseter prominence and create a softer, more balanced lower-face contour. Treatment is planned according to your facial anatomy, muscle strength, and intended result.
You can read our guide explaining Botox for more information about how the treatment works and what to expect.
-
Am I Suitable for Masseter Botox?
-
Masseter Botox may be appropriate if prominent or overactive masseter muscles are contributing to a wider or more square-shaped lower face.
A detailed consultation is required before treatment. Your practitioner will assess your facial structure, jaw muscles, medical history, and aesthetic goals to determine whether Masseter Botox is appropriate for you.
-
Is Masseter Botox Safe?
-
Botulinum toxin type A has an established medical and aesthetic use, but Masseter Botox requires careful assessment and precise placement because treatment can temporarily alter the activity of muscles involved in chewing and facial movement.
Possible side effects of Masseter Botox can include temporary tenderness, bruising, changes in chewing strength, or facial asymmetry. At Dr Nyla Medispa, treatment is planned following a clinical assessment and performed by experienced medical professionals.
-
Can Masseter Botox Slim the Jawline?
-
Masseter Botox can improve the appearance of a wide or square lower face when this is caused by enlarged masseter muscles. As muscle activity reduces, the masseters can gradually become less prominent, creating a slimmer and more balanced facial contour.
It does not remove facial fat or alter the underlying jawbone, so your practitioner will first assess what is contributing to the shape of your lower face.
-
Can Masseter Botox Help With Teeth Grinding or Jaw Clenching?
-
Masseter Botox may help reduce the strength of excessive jaw muscle contractions associated with clenching or teeth grinding. Results vary, and treatment is not appropriate for every patient.
If teeth grinding or jaw discomfort is your primary concern, an appropriate clinical or dental assessment may also be recommended to identify contributing factors and determine the most suitable approach.
-
When Will I See Results From Masseter Botox?
-
The effects of Masseter Botox begin to develop gradually following treatment. Reduced muscle activity may be noticed first, while changes in lower-face contour generally take longer as the masseter muscles gradually become less prominent.
Your practitioner will explain the expected treatment timeline during your consultation, as results vary according to muscle size, strength, and individual response.
-
How Long Does Masseter Botox Last?
-
Masseter Botox is temporary. The effects gradually reduce as normal muscle activity returns, and longevity varies between patients according to factors including muscle strength, metabolism, and the treatment plan.
Follow-up treatment may be considered where appropriate, but treatment frequency should be based on individual assessment rather than a fixed schedule.
-
Will Masseter Botox Affect My Ability to Chew?
-
Masseter Botox is intended to reduce excessive activity in the treated muscles rather than prevent normal jaw movement. Some patients may notice temporary changes in chewing strength, particularly with harder foods, while the treatment is taking effect.
Careful assessment of masseter strength and appropriate treatment planning are important for maintaining normal function while achieving the intended result.
