When most people think of Botox, they think of smoothing wrinkles — but that’s only part of the story. One of the most transformative, non-surgical uses of Botox is in the masseter muscles, the strong muscles along the jawline responsible for chewing and clenching.
At Elase, this advanced technique—often called Masseter Botox—is used to subtly slim the lower face, relieve jaw tension, and restore natural facial balance.
Whether your goal is a more refined contour or relief from teeth grinding and TMJ discomfort, here’s how this treatment works and why precision matters.
What Is Masseter Botox?
Masseter Botox involves carefully injecting small amounts of Botox (botulinum toxin type A) into the masseter muscles on either side of the face. These muscles, located near the back of the jaw, can become overdeveloped from frequent clenching, grinding, or chewing.
By temporarily relaxing the masseters, Botox reduces the muscle’s activity, which can:
-
Soften the appearance of a square or wide jawline
-
Alleviate jaw pain, tension, and headaches associated with TMJ (temporomandibular joint) dysfunction
-
Prevent nighttime clenching or teeth grinding (bruxism)
-
Create a more balanced and contoured facial shape over time
The result? A slimmer, more refined jawline—and, for many clients, a welcome sense of relief from years of tension.
How Does It Work?
Botox works by blocking the nerve signals that cause muscles to contract. When injected into the masseter, it allows the muscle to relax without affecting normal facial movement or chewing function.
At Elase, our medical providers use advanced mapping techniques to determine the precise depth and placement for your unique anatomy. This ensures:
-
Natural results (no “hollow” or over-slimmed look)
-
Symmetry between both sides of the face
-
Comfortable, efficient treatment with minimal downtime
Within 1–2 weeks, you’ll notice a reduction in tension, with continued softening and contouring over the next 4–6 weeks as the muscle gradually relaxes.
Benefits of Masseter Botox
Masseter Botox offers both aesthetic and therapeutic benefits, making it one of the most versatile uses of Botox.
1. Jawline Slimming & Facial Contouring
Overdeveloped masseters can make the lower face appear broader or more squared. Relaxing these muscles allows the face to return to a softer, more V-shaped contour—especially flattering when paired with cheek or chin filler for balance.
2. TMJ Relief & Reduced Tension
For clients struggling with jaw tightness, headaches, or clicking from TMJ disorder, Masseter Botox can provide meaningful relief. By reducing the constant clenching pressure, it lessens inflammation and allows the joint to move more freely.
3. Improved Comfort During Sleep
Many clients grind or clench their teeth at night without realizing it. Botox for the masseters helps minimize this subconscious tension, improving sleep quality and preventing long-term wear on the teeth.
4. Non-Surgical, No-Downtime Solution
Unlike jawline surgery or contouring devices, Masseter Botox is quick (typically under 15 minutes) and requires no recovery time. You can return to work or normal activities immediately.
5. Natural-Looking Results
When performed by skilled injectors, Masseter Botox does not change your ability to smile, chew, or express emotion—it simply relaxes excessive tension while preserving natural movement.
What to Expect at Your Elase Appointment
Every Botox treatment at Elase begins with a personalized consultation. Your provider will assess your facial structure, discuss your goals (aesthetic, functional, or both), and create a customized injection plan.
Here’s what a typical visit looks like:
-
Consultation & Assessment: We’ll evaluate jaw movement, bite alignment, and muscle prominence.
-
Treatment Mapping: The injector marks key points for precise placement.
-
Injection: A few small injections per side are all that’s needed. Most clients describe the sensation as a mild pinch.
-
Aftercare: You can resume normal activities right away—just avoid massaging the area or strenuous exercise for the next 24 hours.
Results begin to appear within days, with peak effects around 4–6 weeks. Depending on your goals, most clients repeat treatment every 3–6 months for ongoing benefits.
Why Precision Matters
Because the masseter is a large and functional muscle, precision in dosage and placement is crucial. At Elase, all injectors are licensed medical professionals with advanced training in facial anatomy and neuromodulator technique.
This expertise ensures results that look refined, balanced, and natural—not frozen or uneven. We also track your results and progress over time, adjusting your treatment plan as your facial muscles adapt.
If your goals include both jawline slimming and TMJ relief, our providers may combine Botox with other complementary therapies, such as skin tightening or filler for enhanced definition and symmetry.
Is Masseter Botox Right for You?
You may be a good candidate if you experience:
-
Jaw tension, soreness, or clicking
-
Frequent headaches or facial tightness
-
Noticeable widening of the lower face
-
Nighttime teeth grinding or worn enamel
-
A desire for a slimmer, more sculpted facial profile
During your consultation, your provider will determine if Botox is appropriate or if another treatment may better suit your needs.
How Long Do Results Last?
The effects of jawline slimming Botox and TMJ Botox typically last 3–6 months. Over time, repeated treatments can gradually train the muscle to remain less active, leading to longer-lasting contouring and comfort.
Maintenance sessions can easily be built into your Elase Beauty Bank Membership, allowing you to enjoy 10-15% off pricing on every treatment and exclusive member-only perks year-round.
