Masseter Botox
Masseter Botox in Miami is a prescription neuromodulator, placed in measured units into the masseter — the jaw muscle used for chewing — by an Aesthetic Nurse Injector. It is commonly considered for jaw tension, teeth grinding and a softer, slimmer lower-face shape. At Activate Beauty in North Miami Beach, every treatment begins with a consultation and is carried out under medical supervision.
A neuromodulator, placed in the jaw muscle
Masseter Botox is a neuromodulator — a prescription product that temporarily reduces the activity of the masseter, the large muscle at the angle of the jaw that you use to chew and clench. It is administered in measured units on each side, with the number of units depending on your anatomy and the plan agreed at your consultation.
It is most often considered by people with jaw tension, teeth grinding (bruxism) or TMJ discomfort, and by those looking for a softer, slimmer outline to the lower face. Because the masseter is a large muscle, this area typically uses a higher number of units than the upper face.
Because it is a prescription treatment, masseter Botox is provided under medical supervision and is not suitable for everyone. A consultation establishes whether it is appropriate for you before anything is administered.
Consultation first, conservative by design
Our approach is unhurried. We assess the masseter and your goals, dose conservatively, and never pressure you to proceed.
-
01
Consultation
We review your history — including any teeth grinding or jaw tension — feel how the masseter contracts when you clench, and confirm whether masseter Botox is appropriate for you. There is no obligation to book a treatment.
-
02
A plan for your anatomy
Placement and the number of units per side are planned around the size and strength of your masseter and your goals — not a fixed template. The masseter typically uses a higher number of units than the upper face.
-
03
The treatment & timeline
A few measured injections are placed in each masseter. Softening is gradual — usually felt over the following two to six weeks — and effects typically last in the region of three to four months. Results often build with repeat sessions over time.

Masseter Botox FAQ
What is masseter Botox?
Masseter Botox is a prescription neuromodulator placed in measured units into the masseter — the large muscle at the angle of the jaw used for chewing. It is administered by an Aesthetic Nurse Injector, following a consultation and under medical supervision. It is commonly considered for jaw tension, teeth grinding and a softer, slimmer lower-face shape.
Does masseter Botox cause jowls or sagging?
When the masseter is assessed and dosed conservatively, the aim is gradual, measured softening rather than over-relaxation. Suitability and dosing are reviewed at your consultation, and we would rather start measured and review than over-treat. Individual results vary.
How long does masseter Botox last?
Effects are temporary and typically last in the region of three to four months before the muscle gradually regains activity. Many people choose to repeat the treatment over time; results and duration vary from person to person and are discussed at your consultation.
How many units of masseter Botox do I need?
The masseter is a large muscle, so it typically uses a higher number of units than the upper face — often in the region of 20 to 25 units per side. The exact number depends on your anatomy and goals and is confirmed at your consultation.
Will my face look slimmer?
Reducing activity in the masseter can, over time, soften a prominent jaw angle in some people, which may give the lower face a slimmer outline. Any change is gradual and varies with individual anatomy; it is assessed and discussed at your consultation. Individual results vary.
Does masseter Botox help teeth grinding or TMJ?
Masseter neuromodulator treatment is sometimes considered to ease jaw tension associated with teeth grinding (bruxism) and TMJ discomfort by reducing how forcefully the muscle contracts. Whether it is appropriate for you is assessed at your consultation, and it may be one part of a wider plan with your dentist or physician.
Is there downtime after masseter Botox?
Most people return to everyday activities the same day. You may notice minor tenderness or small marks at the injection points. Your injector will give you aftercare guidance, including staying upright and avoiding heavy exercise for the rest of the day. Individual experiences vary.
How much does masseter Botox cost in Miami?
Masseter Botox is priced from $8.50 per unit. Because the masseter typically uses a higher number of units (often around 20 to 25 units per side), the total depends on the units planned for you, which is confirmed at your consultation. See the pricing page for starting prices across treatments.
