Masseter botox (jaw slimming) has become one of the most requested medical aesthetic treatments among both women and men in recent years. The reduction of the masseter muscle in the jaw corner through botulinum toxin injection gives the face a more oval and balanced frame. At Veneta Aesthetics Clinic®, we perform this treatment under the supervision of Op. Dr. Atakan Baş, using FDA-approved products in a clinical setting — a non-surgical and fully reversible method. This guide covers everything you need to know about masseter botox.
1. What is Masseter Botox?
The masseter is a powerful facial muscle that connects the lower jawbone to the temple bone and enables chewing movement. Due to genetic predisposition, intense chewing habits (gum chewing, bruxism), or stress, this muscle can become hypertrophic (overdeveloped) over time. Masseter botox uses botulinum toxin type A injected into this muscle to temporarily relax it and reduce its volume. The result: a more refined, oval, and V-line lower face frame.
The treatment is used for both aesthetic (face contouring) and functional (nighttime teeth grinding, jaw pain, TMJ disorders) indications.
2. Who is Masseter Botox For?
Masseter botox may be considered if you have any of the following:
- Wide or square face shape — prominent volume in the lower jaw, "boxy" appearance
- Bruxism — nighttime teeth grinding or clenching
- Jaw and temple pain — associated with TMJ (temporomandibular joint) dysfunction
- Asymmetric jaw — masseter muscle more prominent on one side
- Desire for a more refined V-line face
- Combined with gummy smile (combination treatment)
Whether the treatment is right for you is determined by Op. Dr. Atakan Baş after a clinical examination evaluating facial proportions, bone structure, and actual masseter hypertrophy.
3. Treatment Process: Step by Step
Masseter botox at our Nişantaşı clinic takes approximately 15-20 minutes and follows these steps:
- Consultation & examination — Facial analysis, masseter palpation, muscle volume assessment
- Marking — 3-5 injection points marked at the jaw corner with sterile pen
- Topical anesthesia — Optional cream for sensitivity (usually not needed)
- Injection — 20-40 units of botulinum toxin per side with a fine needle
- Cold compress — To minimize swelling and redness
- Follow-up plan — Control appointment in 2 weeks
You can return to your daily activities immediately after the procedure. There are no stitches, anesthesia, or recovery period.
4. When Will the Effect Appear and How Long Does It Last?
Masseter botox effect develops gradually:
- 3-7 days: Teeth clenching begins to decrease, jaw fatigue lessens
- 2-3 weeks: Visual slimming becomes noticeable
- 6-8 weeks: Maximum slimming visible (muscle atrophy complete)
- 4-6 months: Duration of effect — varies by individual and dose
To maintain results, 2-3 treatments per year are recommended. With regular application, the muscle may develop a more permanent slimming habit over time, which can extend the interval between treatments.
5. Side Effects and Risks
When applied with proper anatomical knowledge, FDA-approved products, and by an experienced plastic surgeon, masseter botox is a safe procedure. However, like any medical treatment, possible side effects exist:
Common (temporary):
- Mild redness, swelling, or bruising at injection site (1-3 days)
- Slight fatigue when chewing hard foods in the first 1-2 weeks
- Mild jaw pain (usually resolves within 24 hours)
Rare (minimized with proper technique):
- Asymmetry (usually self-resolves within 2-3 weeks)
- Temporary smile changes (due to incorrect injection site)
- Excessive slimming (dose overage; reversible)
When applied by a Plastic, Reconstructive and Aesthetic Surgery specialist like Op. Dr. Atakan Baş with proper anatomical knowledge and appropriate dosing, the occurrence of these risks is very low.
6. Masseter Botox vs. Chin Filler: What's the Difference?
The two are often confused but serve different purposes:
- Masseter botox: Slims a wide/boxy jaw. Uses botulinum toxin. Ideal for V-line.
- Chin filler (hyaluronic acid): Adds volume and projection to a weak/recessed chin. Extends the chin point forward and downward.
In some cases, both treatments are applied together: the side masseter muscle is reduced while the chin tip is brought forward with filler. This combination is called "chin contouring" and is personalized by Op. Dr. Atakan Baş based on facial proportions.
7. Post-Treatment Care: 7-Day Process
For ideal results, follow these guidelines for the next 7 days:
- First 4 hours: Avoid lying down (to prevent botulinum toxin from spreading to other muscles)
- First 24 hours: No intense exercise, sauna, hammam, or hot shower
- First 48 hours: No facial massage, makeup application, or peeling
- First 7 days: Limit hard/chewy foods (candy, hard bread crust, gum)
- General: Drink plenty of water, protect your face from the sun
If swelling or minor bruising occurs, apply cold compress to the area. Blood thinners (aspirin, ibuprofen, vitamin E, fish oil) should not be used 5-7 days before and after the procedure — they increase bruising risk.
8. Masseter Botox Pricing
Masseter botox prices in Turkey vary based on:
- Unit amount used (20-40 U per side, depending on individual)
- Brand (Allergan/Botox®, Dysport®, Xeomin® may differ)
- Physician's specialty (plastic surgeon, dermatologist, etc.)
- Clinic's location and standards
For specific pricing, a free consultation is recommended. Remember that low-priced offers almost always involve diluted product or non-specialist practitioners — in an anatomically sensitive area like the masseter, the risk far exceeds the cheap price.

10. Frequently Asked Questions
Is masseter botox painful?
No. It usually doesn't even require topical anesthesia. Numbing cream can be applied before the procedure for sensitive patients.
Does chewing become difficult after the first treatment?
Slight fatigue may be felt when chewing hard foods in the first 1-2 weeks; this is temporary and does not interfere with your daily diet.
Are results permanent?
No, they are reversible. The effect lasts 4-6 months. If not reapplied, the muscle gradually returns to its original volume.
Will masseter botox cause my face to sag?
NO when applied at the correct dose and proper anatomy. Rarely, "cheek hollowing" can occur with overdoses or incorrect placement — which is why choosing an experienced specialist is critical.
Is it applied to men too?
Yes. As part of the "Brotox" (men's botox) trend, masseter botox is very popular among men too; especially for jaw enlargement caused by bruxism.
Can it be applied during pregnancy?
No. All botulinum toxin treatments are contraindicated during pregnancy and breastfeeding.
Will my teeth grinding (bruxism) improve too?
Yes, one of the strongest functional benefits of masseter botox is the reduction of bruxism. Many patients report that jaw pain and morning headaches disappear.
Is the consultation free?
Yes, the first consultation at Veneta Aesthetics Clinic® is free. You can reach us via WhatsApp or +90 212 561 23 22.
