masseter Botox King's Cross
Masseter Botox King's Cross
Targeted muscle-relaxing injections for enlarged or overactive masseter muscles. They may reduce jaw tension and create a slimmer lower-face outline over time.
What it is and how it works
The masseter is a powerful chewing muscle at the angle of the jaw. When it is enlarged or overactive, carefully placed muscle-relaxing treatment can reduce its activity, which may ease tension and gradually reduce muscular width in the lower face.
The treatment only changes the muscular component of the jaw. Bone structure, soft tissue, dental problems and other causes of pain require different approaches, so your doctor assesses the jaw in motion before recommending it.
Who it is for
- A broad lower face caused by prominent masseter muscles
- Jaw clenching or tension where treatment is clinically suitable
- Clients seeking gradual, non-surgical contouring
How treatment is mapped
The masseter is examined at rest and during clenching so treatment follows the true muscle border and any asymmetry.
- The masseter runs from the cheekbone to the angle of the jaw and provides much of the force used for chewing.
- Your doctor assesses muscle thickness, bite pattern, facial width and whether tension is muscular, dental or joint-related.
- Placement remains within the safe masseter zone to avoid nearby smile muscles and the parotid gland.
What results look like
Tension may ease before visible slimming develops. Facial change is gradual and depends on muscle size and anatomy.
Honest timeline
Muscle relaxation begins over the first weeks. Contour change is usually assessed from four to eight weeks and may continue to develop beyond that.

One treatment appointment; review and future maintenance depend on clinical response.
Safety and downtime
Your doctor reviews your medical history, medicines and treatment area before confirming suitability. Treatment is postponed when it would not be clinically appropriate.
Tenderness, small bumps or bruising can occur. Temporary chewing fatigue is possible and is discussed during consent.
Skin-tone guidance
The treatment can be considered across skin tones. Technique and aftercare are adjusted individually, with particular attention to bruising, inflammation and the risk of post-inflammatory pigmentation.
Frequently asked questions
Is this the same as jawline filler?
No. This treatment reduces activity in the masseter muscle; filler adds volume. They suit different anatomies and goals.
Will it help every type of jaw pain?
No. Jaw pain has several causes and may require dental or medical assessment. We only treat when appropriate.
