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. Dr Azra Vaziri provides this treatment in Dubai and Abu Dhabi.

What Is Masseter Botox
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.
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.
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 and Abu Dhabi — book a consultation at whichever location suits you.
Two Treatment Goals — One Procedure
Aesthetic: Jaw Slimming / V-Shape Face
- Slims a wide, square, or heavy lower jaw
- Creates a more tapered, V-shaped face contour
- Softens a masculine jawline in women
- Popular “Barbie Botox” look — lifted, sculpted lower face
- Improves facial proportions and balance — see face contouring
- Often combined with chin filler for complete lower face reshaping
Results: Visible slimming in 4–6 weeks. Maximum effect at 2–3 months. Multiple sessions recommended for dramatic results.
Medical: Bruxism & TMJ Relief
- Reduces teeth grinding force (bruxism)
- Relieves TMJ (temporomandibular joint) pain
- Reduces jaw tension headaches
- Protects teeth from grinding damage
- Reduces morning jaw soreness and fatigue
Results: Clenching force reduces within 1–2 weeks. Pain relief often noticeable within days. Repeat every 4–6 months.
How Masseter Botox Works — Step by Step
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.

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.
Results Timeline
- 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.
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.

Who Is a Good Candidate
- Wide, square, or heavy lower jaw you want to slim
- Bruxism (teeth grinding) — daytime or nocturnal
- TMJ pain, jaw tension, or jaw-related headaches
- Seeking a V-shape or heart-shape face contour
- Combining with jawline filler for lower face reshaping
- Morning jaw soreness or fatigue
- Jaw width from bone structure (not muscle) — Botox won’t help

Dr Azra palpates the masseter during consultation to determine whether width is muscular (treatable) or skeletal (not treatable with Botox).
