What is Masseter Botox?
Masseter Botox is a refined, non-surgical treatment that involves precise injections of botulinum toxin type A into the masseter muscles along the jawline, responsible for chewing and clenching.
By temporarily relaxing these muscles, the treatment softens their activity, reduces tension, and gradually refines the lower face. The result is a smoother, more contoured jawline and relief from discomfort associated with jaw tightness or grinding.
Masseter Botox is best suited for those who:
- Experience jaw tension, clenching, or bruxism (teeth grinding) that causes discomfort or muscle fatigue.
- Notice a wider or square jawline caused by enlarged masseter muscles and desire a more slim, V-shaped contour.
- Have facial asymmetry linked to uneven muscle activity.
- Prefer a non-surgical solution to achieve a more balanced and refined lower face.

FAQs
Is masseter Botox safe?
Masseter Botox has a well-established safety profile, backed by clinical studies in thousands of patients. Most side effects are mild and temporary, such as bruising, tenderness, or jaw tightness at the injection site, with rare fatigue or flu-like symptoms settling within a few days. Choosing a GMC-registered doctor keeps these risks to a minimum.
How many units of Botox do I need for masseter reduction?
Dosage depends on your muscle size and goals, confirmed at consultation. Most adults need 20 to 40 units per side, though larger or more developed masseter muscles, often in men, may need up to 50 units per side. Underdosing risks a less noticeable result, so your doctor tailors the amount to your anatomy.
Is masseter Botox painful?
Most patients find it more manageable than expected: typically rated 2 to 4 out of 10 for discomfort. The injection goes into muscle rather than superficial skin, so it can feel slightly deeper than forehead Botox, but it’s not usually described as sharp or severe.
How much does masseter Botox cost?
Masseter Botox at Dr Hass Clinic is £350.
What happens during masseter Botox recovery? Can I still eat and talk normally?
Eating, talking, and chewing are unaffected in the days after treatment. You may notice mild tenderness or swelling for a few hours, with jaw tension and bruxism relief typically beginning within 1 to 2 weeks and visible jawline slimming developing gradually over 6 to 8 weeks as the muscle reduces in bulk.
How long do masseter Botox results last?
Results typically last 6 months. With repeated treatments, the muscle can progressively reduce in size, leading to longer-lasting slimming and sustained relief from jaw tension. Maintenance sessions every 4 to 6 months help keep results consistent.
