Is masseter Botox FDA-approved? Four things Portland clients ask
No. Botox Cosmetic is FDA-approved for frown lines, crow's feet, forehead lines and neck bands, not for the masseter. Using it to slim the jaw is an off-label use that is widely described in the medical literature. We explain what off-label means, the evidence and the risks at your Portland assessment before you decide.
- "Jaw Botox works in a few days."
The muscle relaxes over weeks. Studies report onset at about 2 to 4 weeks, with the largest drop in muscle strength around weeks 10 to 12.
- "Everyone gets the same dose."
Studies use a wide range, roughly 10 to 45 units per side. Muscle size, strength and the difference between your two sides decide your units.
- "It is a treatment for TMJ."
Botox Cosmetic is not FDA-approved for TMJ disorders or teeth grinding. Jaw pain, clicking or locking needs your dentist or medical provider first.
- "You will not be able to chew."
Some people notice weaker chewing for a while, which reviews describe as common and temporary. Tough or chewy foods may take more effort at first.

- Soften the angle.

How many units of Botox for masseter slimming?
There is no FDA-labeled masseter dose. Published studies use roughly 10 to 45 units of onabotulinumtoxinA per side, and larger, stronger muscles often need more. Your Portland injector feels the muscle as you clench, compares both sides, then sets your units and quotes your total.
Members pay $550 (Glow, $11 a unit) or $500 (Elite, $10 a unit) for the same 50 units. This is an example; your units are set at assessment.

What does masseter Botox cost in Portland with a membership?
Masseter Botox is billed by the unit: $12 at regular pricing, $11 for Glow members and $10 for Elite members. Both sides are treated in one visit, so your total depends on the units your muscles need, and we confirm that number with you before any injection.
Prices subject to change. Member discounts can't be combined with specials, packages or promotions. See membership terms, the full price menu and payment plans.
Compare membershipsWhen will I see results, and how long does jaw Botox last?
The change is gradual. Studies report onset at about 2 to 4 weeks, and one large study measured the biggest drop in muscle strength around weeks 10 to 12. In that study, about half of people needed a second treatment 4 to 7 months later. Repeat sessions can help the slimmer shape hold for longer.
Figures from studies summarized in a 2025 review: muscle thickness change, the share retreated 4 to 7 months later, and volume a year after three sessions. Individual results vary.

Who is a good candidate for masseter Botox?
Adults whose lower face looks wide or square because of muscle bulk, rather than bone shape, fat or loose skin. A quick check is to clench your teeth: if a firm bulge rises at the back of the jaw, the muscle is part of the shape. If the fullness comes from fat or laxity, another treatment may fit better, and we will tell you so.
A square or wide lower face
When the jaw looks broad from the front, relaxing the masseter can taper the lower face toward a softer, more oval outline.
Masseter Botox for men
Many men want a leaner jaw without losing a strong angle. We start with conservative units and review the change at your follow-up.
Pair masseter Botox with jawline treatments
Masseter Botox narrows the angle of the jaw. If you also want more definition along the chin and jawline, or less fullness under the chin, filler or Kybella can be planned at the same consultation, with the order and spacing set by your injector.

Masseter Botox in Portland: FAQs
Questions we hear most at our SE Stark Street clinic.
How much does masseter Botox cost in Portland?
Masseter Botox is $12 a unit at Cosmetiq Medicine in Portland, $11 for Glow members and $10 for Elite members. Both sides are treated, so a plan of 50 units comes to $600 at the regular price. Your units and total are confirmed before treatment.
How many units of Botox do you need for the masseter?
There is no FDA-labeled masseter dose. Published studies use roughly 10 to 45 units of onabotulinumtoxinA per side, with larger, stronger muscles usually needing more. Your injector sets your units after feeling the muscle as you clench.
Is masseter Botox FDA-approved?
No. Botox Cosmetic is FDA-approved for frown lines, crow's feet, forehead lines and neck bands. Treating the masseter to slim the jaw is an off-label use. We explain the evidence, risks and alternatives at your assessment before you decide.
How long does masseter Botox take to work?
It is gradual. Studies report onset at about 2 to 4 weeks, and one large study measured the biggest drop in muscle strength around weeks 10 to 12. The slimming you see follows the muscle as it gets smaller, so photos at 2 and 3 months are the fair comparison.
How long does jaw Botox last?
In one large study summarized in a 2025 review, about half of people needed a second treatment 4 to 7 months after the first. Results vary, and repeat sessions on a regular schedule can help the slimmer shape last longer.
Can masseter Botox help with teeth grinding or TMJ?
Botox Cosmetic is not FDA-approved for teeth grinding or TMJ disorders, and we treat the masseter for its shape. Jaw pain, clicking, locking or headaches should be checked by your dentist or medical provider first, since they can have other causes.
What are the side effects of masseter Botox?
Reviews list temporary chewing weakness, tenderness or bruising where you were injected, and brief asymmetry. Less often, people notice smile changes, a bulge when clenching or some soft-tissue sagging. Rarely, toxin effects can spread and cause swallowing or breathing problems.
Will masseter Botox change my smile?
It should not when the injections stay in the lower, bulky part of the muscle. Smile changes are an uncommon effect when product reaches nearby smile muscles, which is why placement is planned to your anatomy and reviewed at your follow-up.
Can men get masseter Botox?
Yes. Many men want a leaner lower face without losing a strong jaw angle. We usually start conservatively, review at follow-up and adjust units at the next visit if you want more change.
Is masseter Botox offered at the Vancouver, WA clinic too?
Yes. Masseter Botox is available at our Portland clinic at 10735 SE Stark St, Suite 206, and at our Vancouver clinic at 12000 SE Mill Plain Blvd, with the same menu prices. Book either location online or call or text (503) 572-2675.
