Masseter Botox in Los Angeles: Jaw Slimming & Facial Contouring
Last updated: June 2026If you wish your jawline looked slimmer, softer, and more sculpted, masseter Botox is one of the most popular non-surgical ways to refine the lower face. At Beauty Ranch Medical Spa in Brentwood, masseter Botox is a quick, needle-precise treatment that can help slim a wide or square jawline and create a more balanced, tapered facial shape.
Here's everything you need to know about masseter Botox in Los Angeles — how it works for facial contouring, what it costs, how many units you'll need, when you'll see results, and what to expect.
What Is Masseter Botox?
The masseter is the large muscle on each side of your jaw that you use to chew. For some people — often from genetics or habit — this muscle is naturally larger, which can give the lower face a wider, more square appearance.
Masseter Botox uses the same neuromodulator (botulinum toxin) as cosmetic Botox, placed directly into the masseter muscle. By gently relaxing the muscle so it's used less, the muscle can soften and gradually slim over time. The aesthetic result is a more tapered, V-shaped lower face and a smoother, more contoured jawline.
What Masseter Botox Can Do for Your Look
Clients choose masseter Botox at Beauty Ranch for facial contouring goals like:
- Softening a wide, square, or "overdeveloped" jawline
- Creating a slimmer, more V-shaped or heart-shaped lower face
- Balancing facial proportions, especially in profile
- A non-surgical alternative to more invasive jaw-contouring options
How Does Masseter Botox Work?
After a short consultation, your provider cleanses the area and places a series of small injections into the masseter muscle on each side of the jaw using a very fine needle. The treatment usually takes about 10–15 minutes with little to no downtime.
Because the muscle relaxes and slims gradually with less use, the contouring effect builds over several weeks to a couple of months. Many clients describe the experience as quick and very tolerable.
How Many Units of Botox for the Masseter?
Masseter dosing is higher than for areas like the forehead or crow's feet because it's a large, strong muscle. The exact number of units depends on your muscle size, your contouring goals, and whether it's your first treatment. Your provider will recommend a personalized dose at your consultation — this is not a one-size-fits-all treatment, and precise placement is key to a natural result.
How Much Does Masseter Botox Cost in Los Angeles?
At Beauty Ranch, Botox (including masseter treatment) is priced per unit, so your total reflects the units your jaw needs. Because the masseter requires more units than smaller facial areas, it's best to get an exact quote at a quick consultation.

Masseter Botox Before and After: What Results Look Like
The change is gradual and natural — friends often think you simply look more refreshed and sculpted rather than "done." The slimming, contouring effect typically develops over several weeks. Muscle-relaxing results generally last about 3–4 months, and with consistent treatments the muscle often stays smaller over time, so some clients find they need fewer units at future visits.
Is There Any Downtime?
Masseter Botox has minimal downtime — most people return to their day immediately. Mild tenderness, small bumps, or slight bruising at the injection sites can occur and settle quickly. As with any injectable, the most important factor in a smooth, natural result is an experienced, skilled injector who understands jaw anatomy and facial balance — exactly what you get with Nurse Jamie and our team.
