Masseter Botox is a non-surgical facial slimming treatment designed to soften a square or bulky jawline by relaxing the masseter muscles. This procedure is especially popular among individuals seeking a slimmer, more contoured lower face without surgery or downtime.
By reducing the overactivity of the jaw muscles, Masseter Botox helps create a more balanced facial shape while maintaining natural expression.
Masseter Botox is widely recognized as one of the best non-surgical face slimming treatments available today. It is particularly effective for individuals with a strong jawline, square jaw shape, or round face caused by enlarged masseter muscles.
As the muscle activity decreases, the lower face appears slimmer, more V-shaped, and more proportionate to the rest of the facial features. This makes Masseter Botox a preferred option for facial slimming without fillers or surgery.
Masseter Botox offers multiple aesthetic benefits beyond jaw slimming. It helps create facial harmony by reducing excessive lower-face volume while preserving natural movement.
Patients often choose this treatment because it is non-surgical, effective, and requires minimal recovery time.

Masseter Botox may be suitable if you:
A consultation is essential to confirm that jaw width is caused by muscle hypertrophy rather than bone structure.

Most patients notice gradual jaw slimming within 4–6 weeks after treatment. As the masseter muscle reduces in size, the jawline becomes slimmer and the lower face looks more refined.
Before and after Masseter Botox results typically show:
Results improve progressively with repeat treatments.
Masseter Botox is a quick in-office procedure. Small amounts of Botox are injected directly into the masseter muscle on each side of the jaw. The injection sites are carefully selected to ensure even muscle relaxation and natural results.
The procedure usually takes less than 15 minutes and does not require downtime.
The effects of Masseter Botox typically last between 4 to 6 months. With repeated treatments, muscle reduction can become more pronounced and longer-lasting, allowing for extended intervals between sessions.
Masseter Botox is considered safe when performed by an experienced injector. Mild swelling, tenderness, or temporary chewing fatigue may occur shortly after treatment. Serious side effects are rare.
Concerns about facial sagging are usually related to improper technique or excessive dosing, which is why professional assessment is essential.
Pricing for Masseter Botox depends on muscle size, required units, and individual facial anatomy.
| Treatment Area | Average Price Range |
|---|---|
| Masseter Botox (Both Sides) | Varies by consultation |
| Jawline Slimming Botox | Varies by consultation |
