Masseter Botox in Dubai
Masseter Botox slims a wide or square jaw by relaxing the masseter muscle — one of the strongest muscles in the body. As the muscle relaxes, it gradually atrophies, creating a slimmer, more tapered V-shape face. Also known as jaw slimming Botox or Barbie Botox, it treats bruxism (teeth grinding) and TMJ-related jaw pain.

What Is Masseter Botox
In Simple Terms
Masseter Botox — also called jaw Botox, jawtox, jaw slimming Botox, jawline slimming Botox, TMJ Botox, or Barbie Botox — relaxes the masseter muscle so it gradually shrinks over 4–6 weeks, creating a slimmer, more V-shaped lower face. The same treatment relieves teeth grinding (bruxism), TMJ jaw pain, and tension headaches. Treatment takes 15 minutes with no downtime.
The masseter is one of the strongest muscles in the human body — responsible for chewing, clenching, and grinding. In many people, it is larger than necessary, either genetically (common in East Asian and Middle Eastern facial anatomy) or from habitual clenching and teeth grinding (bruxism). An enlarged masseter creates a wide, square lower face.
Botox injected into the masseter weakens the muscle over 1–2 weeks, reducing clenching force and jaw tension. Over the following 4–6 weeks, the muscle gradually atrophies (shrinks) because it’s being used less forcefully. The result: a slimmer, more V-shaped jawline and — for bruxism patients — significant relief from jaw pain, headaches, and tooth damage.
This is one of the most popular aesthetic treatments at Dr Azra’s clinic — particularly among women seeking a V-shape or heart-shape lower face, and patients of all genders suffering from bruxism.
Jaw Botox, Jawtox, Jawline Slimming — One Treatment, Many Names
Patients ask for this treatment under a dozen different names. Jaw Botox, jawtox, jaw slimming injections, jawline slimming, square jaw Botox and Barbie Botox all describe the same procedure: botulinum toxin placed into the masseter muscle. The clinical name is masseter Botox, because the masseter is the muscle being treated — not the jawbone, and not the jawline itself. The distinction matters at consultation, because jawline slimming and jawline filler pull in opposite directions: one narrows the lower face, the other sharpens and defines its border.
Jaw Botox / Jawtox
Everyday shorthand for masseter Botox. Same muscle, same injection points, same appointment — only the name is different.
Jaw & Jawline Slimming
Describes the outcome rather than the method: a narrower, more tapered lower face as the masseter gradually reduces in size.
Square Jaw Botox
Used when the concern is a wide or square lower face. Dr Azra assesses at consultation whether that width is muscle or bone.
Barbie Botox
Masseter Botox combined with trapezius Botox in one session, for a slimmer jaw and a longer-looking neckline.
Whichever name you searched for, the assessment is the same: Dr Azra Vaziri palpates the masseter, checks how much of the width is muscle, and confirms whether jaw slimming, face contouring, or a combination fits your goal. Consultations are available in Dubai — book a consultation at whichever location suits you.

How Masseter Botox Works — Step by Step
Assessment
Dr Azra palpates the masseter while you clench, assessing muscle size and hypertrophy.
Injection
3–5 points per side into the bulk of the masseter. 15 minutes. Minimal discomfort.
Muscle Relaxation
Week 1–2: Clenching force reduces. Bruxism relief begins. Jaw tension eases.
Slimming
Week 4–6: Muscle atrophies visibly. Jaw appears slimmer. Maximum effect at 2–3 months.
Masseter Botox Before and After
Masseter Botox produces gradual, progressive changes to the jaw — not immediate transformation. Here is what to expect at each stage:
Day 1–7
No visible jaw change yet. Clenching force begins to reduce. Bruxism patients may notice less tension almost immediately.
Week 1–2
Significant bruxism relief. Morning jaw soreness decreases. Grinding force noticeably reduced. Headaches begin to ease.
Week 4–6
Visible jaw slimming begins. The muscle has atrophied enough to change the lower face contour. The V-shape effect becomes apparent.
Month 2–3
Maximum slimming. Jaw visibly narrower. Heart-shape and V-shape face contour most apparent. Best results after 2–3 cumulative sessions.
* No before-and-after photograph of masseter Botox is published yet. Botox results for other areas are published here with the patient’s written consent, in line with UAE medical advertising regulations — see the Botox page. At your consultation Dr Azra shows you jaw-slimming cases similar to your own.
Masseter Botox vs Jawline Filler — Different Goals
This is one of the most common questions patients ask. The answer is simple — they do opposite things and are often combined:
Adding chin filler to the combination creates a comprehensive lower face reshaping — one of the most transformative non-surgical results Dr Azra offers.
| Factor | Masseter Botox | Jawline Filler |
|---|---|---|
| Purpose | Slims and narrows the jaw | Adds definition and structure |
| Mechanism | Relaxes muscle → atrophy → slimmer | Adds volume along jawline |
| Best for | Wide/square jaw, bruxism, TMJ | Weak jawline, jowls, definition |
| Combined? | Yes — Botox slims width + filler adds definition = sculpted, contoured lower face |
Results Timeline
With repeated treatments (2–3 sessions), the masseter progressively reduces in size, and the slimming effect lasts longer between sessions. For post-treatment guidance, see the Botox aftercare guide.
- Day 1–7: No visible change in jaw shape yet. Clenching force begins to reduce. Some patients notice less jaw tension.
- Week 1–2: Bruxism patients notice significant reduction in grinding force. Morning jaw soreness decreases. Headaches may reduce.
- Week 4–6: Visible jaw slimming begins. The muscle has been weakened long enough to start atrophying (shrinking in size).
- Month 2–3: Maximum slimming visible. Jaw appears noticeably narrower. V-shape effect most apparent.
- Month 4–6: Effects gradually wear off. Muscle begins to regain strength and size. Maintenance treatment recommended.

Who Injects Your Masseter — Dr Azra Vaziri’s Training
The masseter sits next to muscles you do not want relaxed, and the difference between a slimmer jaw and a changed smile is a few millimetres of depth and position.
Every Masseter Botox appointment at this clinic is assessed and injected by Dr Azra Vaziri herself — a DHA- and DOH-licensed aesthetic physician with more than 20 years of experience, practising aesthetic medicine since 2004.
Training behind the injection
- Think-In, Anatomy & Aesthetic Treatment Workshop (2023) — facial anatomy training; in the lower face the muscle you must avoid is next to the one you are treating.
- Belotero and Xeomin injection workshops — Merz Aesthetics distributor in Iran (2015–2023) — she ran neurotoxin injection training for other physicians.
- Speaker — IMCAS World Congress 2024 (Paris), and Dubai Derma in 2023 and 2026
Who Is a Good Candidate
Suitable Candidates

Frequently Asked Questions
How many units of Botox for the masseter?
25–50 units per side (50–100 total). Women typically 25–35 per side; men 35–50. Higher doses for very strong or hypertrophied masseters. Full units guide →
How much does masseter Botox cost in Dubai?
AED 1,400–3,000 depending on the brand (Korean 1,400, Dysport 2,400, Allergan 2,700, Xeomin 3,000). Masseter Botox is priced per area, not per unit. Multiple sessions (2–3) typically recommended for optimal jaw slimming. See our Botox pricing page for all areas.
How long until I see jaw slimming results?
Bruxism relief: 1–2 weeks. Visible jaw slimming: 4–6 weeks. Maximum slimming: 2–3 months. The masseter must atrophy (shrink) over time — this isn’t immediate like upper face Botox.
How long does masseter Botox last?
4–6 months — longer than upper face Botox. With repeated treatments, the muscle becomes progressively smaller and results last longer. Aftercare guide →
What is Barbie Botox?
Barbie Botox is a popular term for masseter Botox combined with trapezius Botox (Traptox) — the combination that slims both the jaw and the neck/shoulder area, creating an elongated, V-shaped facial silhouette reminiscent of a Barbie doll. At Dr Azra’s clinic, this can be achieved by combining masseter Botox with Botox in the trapezius during the same session.
Can masseter Botox help with teeth grinding?
Yes. By weakening the masseter, Botox reduces clenching and grinding force. Many patients report significant relief from jaw pain, headaches, and tooth damage from bruxism.
What is the difference between masseter Botox and jawline filler?
Opposite purposes. Masseter Botox slims and narrows the jaw (removes width). Jawline filler adds volume and definition (creates structure). Many patients combine both for a sculpted lower face.
Will masseter Botox affect my chewing?
At therapeutic doses, normal chewing is not affected. You may notice slightly reduced bite force with very hard foods in the first few weeks. You have multiple chewing muscles — the masseter is just one of them.
Is jawtox the same as masseter Botox?
Yes. Jawtox, jaw Botox, jaw slimming injections and jawline slimming Botox are all informal names for masseter Botox — botulinum toxin placed into the masseter muscle to narrow a wide or square lower face. Jawline filler is a different treatment entirely.
Do you offer masseter Botox in Abu Dhabi?
Yes. Dr Azra Vaziri sees patients at two clinics: Prof Sakla Spanish Eye Clinic on Sheikh Zayed Road, Dubai, and — on Wednesdays — Louvre Medical Clinic in Abu Dhabi. Choose whichever is closer to you. Contact the clinic to arrange a consultation at whichever location is easier for you.
How many sessions do I need for jaw slimming?
Meaningful slimming after 1 session, but 2–3 sessions spaced 4–6 months apart produce the most dramatic results as the muscle progressively atrophies.
