What Is Masseter Botox?
The masseter is the large chewing muscle that sits at the angle of your jaw, on each side. In some people — particularly those who grind or clench their teeth — this muscle becomes enlarged and overactive. The result is a widened, squarer lower face and often chronic jaw tension, headaches, and tooth wear.
Botulinum toxin injected into the masseter causes the muscle to partially relax and, over time, reduce in size. This achieves two things simultaneously:
- Aesthetic slimming — the lower face narrows, creating a softer, more oval or V-shaped profile
- Functional relief — jaw tension, grinding (bruxism), clenching, and associated headaches are significantly reduced
It's one of the few aesthetic treatments that genuinely improves quality of life as well as appearance.
Who Is It For?
Masseter botox is suitable for people who:
- Have a wide or square lower jaw they'd like to soften
- Grind or clench their teeth (bruxism), especially at night
- Experience jaw tension, jaw ache, or tension headaches
- Want to achieve a more oval or V-shaped facial profile
- Have been told by a dentist that they're damaging their teeth through grinding
It works particularly well in combination with other facial treatments — cheek filler or a full-face anti-wrinkle package — as part of an overall facial harmony plan.
What to Expect
Treatment
Your doctor will palpate the masseter muscle to assess its size and inject botulinum toxin at precise points on both sides. The procedure takes 15–20 minutes. Discomfort is minimal.
Results
- Functional relief (grinding, tension) begins within 1–2 weeks
- Aesthetic slimming develops gradually as the muscle reduces in bulk — typically visible at 6–8 weeks, with optimal results at 3 months
- The slimming effect is progressive with repeat treatments
Duration
Results last 4–6 months for functional relief. Aesthetic slimming may persist longer with regular treatment, as the muscle progressively reduces in size.
Aftercare
- Avoid chewing hard or chewy foods for 24–48 hours
- No massage of the jaw area for 2 weeks
- Standard anti-wrinkle aftercare applies
Frequently Asked Questions
The change is gradual and natural-looking. The lower face softens rather than transforms. Most patients describe looking like a slightly better version of themselves — not a different person.
Yes — this is one of the most well-supported uses of botulinum toxin. Relief from grinding, clenching, and associated jaw pain is typically experienced within 1–2 weeks.
Normal chewing is unaffected. The masseter is a powerful muscle and the dose used reduces — not eliminates — its activity. Some patients notice slightly reduced bite force in the first few weeks, which normalises.
Most patients start to see meaningful aesthetic slimming after 2–3 treatments, spaced 4–6 months apart. For bruxism relief, a single treatment is effective and many patients return every 4–6 months.
Yes. Men with a wide or heavy jaw often see particularly dramatic and satisfying results. Higher doses are used to account for greater muscle mass. Book Masseter Botox → *All treatments at Hinoki Aesthetics are performed exclusively by our qualified medical doctor.*
