Botox can slim the jawline by relaxing the masseter muscles, which reduces muscle size and creates a more contoured lower face. The treatment is non-surgical and also helps relieve jaw tension, teeth grinding, and TMJ-related pain.
Masseter Botox works differently than the wrinkle-smoothing injections you might know about. This treatment actually shrinks those overworked jaw muscles to create a slimmer, more V-shaped face. Think of it as a gym membership cancellation for your jaw muscles.

Yes, Botox can make your jawline noticeably slimmer. The injections weaken your masseter muscles, which gradually shrink over the following weeks. Most people see their square jaw soften into a more tapered, feminine shape.
For men wanting to tone the face without sacrificing any perceived jawline, this is still an effective approach to achieve that outcome
But here’s the bonus: many patients find their jaw pain disappears too. No more morning headaches from nighttime grinding. No more TMJ flare-ups. Your face looks better and feels more comfortable.
Masseter Botox works best for people whose wide jawline comes from muscle, not bone. If you can feel thick, prominent muscles when you clench your teeth, you’re probably a good candidate.
Perfect candidates often struggle with teeth grinding, jaw clenching, or TMJ pain. They want facial slimming without surgery or lengthy recovery time.
Keep in mind that the FDA hasn’t officially approved Botox for jaw slimming yet. Doctors use it “off-label,” which means they’re applying an approved treatment in a new way. Thousands of patients get this treatment safely every year. (1)
Your provider starts by feeling your jaw muscles while you bite down hard. They’re mapping out exactly where your muscles are thickest and strongest.
You’ll get about 30-60 units of Botox injected into each side of your jaw. The whole process takes maybe 10 minutes. Most people describe it as quick pinches—uncomfortable for a second, then over.
Botox needs time to weaken the muscle and create visible changes.
Week 1-2: Your jaw might feel slightly different, but you won’t see much yet
Week 3-4: Friends start asking if you did something different
Week 6: Full results appear—your face looks noticeably slimmer
Results stick around for 3-6 months. Many people find that regular treatments train their muscles to stay smaller, so future sessions need less Botox.
Expect to pay $600-1,200 per session. Botox costs $10-30 per unit, and jaw treatments typically need 60-120 units total.
Men usually need more units than women because their jaw muscles tend to be larger. Your first treatment might cost more, but maintenance sessions often need fewer units.
Botox shrinks bulky muscles to slim your face. Filler adds volume to create sharper angles and definition.
If your jaw looks wide because of thick muscles, choose Botox. If your jawline lacks definition or sharpness, filler works better. Some people get both treatments for complete lower face reshaping.
Jawline Botox works best for face width caused by muscle overdevelopment. If your jaw width comes from bone structure, Botox cannot address that underlying issue. Surgical jaw reduction may be your only option in those cases.
Surgical procedures involve bone reshaping and require weeks of recovery time. Botox offers a non-invasive alternative with zero downtime and gradual, natural-looking results.
Some patients combine jawline Botox with other treatments for enhanced results. Kybella injections dissolve chin fat for fuller lower-face contouring. Dermal fillers can add definition to areas that Botox cannot address.
Your provider can help determine which combination of treatments will best achieve your aesthetic goals based on your facial structure and desired outcome.
