Masseter Botox® in Los Angeles

Your masseters are the chewing muscles at the back of your jaw. When they're overworked by clenching, grinding or simply genetics, they can grow bulky, giving the lower face a wide, square look and leaving your jaw tight and sore.

Masseter Botox® relaxes these muscles. Clenching and grinding ease, jaw tension lets up, and as the muscle slims over the following weeks, the lower face looks softer and more tapered. Treatment takes minutes, with no surgery and no downtime.

Masseter Botox® Can Help With

  • A wide, square jawline
  • Daytime clenching
  • Nighttime teeth grinding
  • TMJ tension & jaw soreness
  • A bulky lower face
  • A more tapered face shape

Masseter Botox® for Men

Plenty of men want to keep a strong, square jaw, and that's fine. We can dose to ease clenching and grinding while your jawline stays defined. If a bulky masseter is widening your face, a fuller treatment slims it for a leaner, sharper look. Your injector tailors the plan to the result you want. See Brotox for everything else we treat for men.

Frequently Asked Questions

Does masseter Botox® hurt?

Most people feel a few quick pinches. It's over in minutes, and you can go straight back to your day.

How long until I see results?

Relief from clenching often starts within one to two weeks. The slimming builds gradually as the muscle relaxes and is usually visible after about four to six weeks.

Will it change how I chew or smile?

You'll chew normally, though some people notice their jaw tires a little sooner with tough foods for the first few weeks. Your smile is controlled by different muscles, and careful placement keeps it natural.

How many units will I need?

It depends on the size and strength of your masseters and whether your goal is relief, slimming or both. Larger, stronger muscles, which are common in men, usually need more. Your injector will recommend a dose at your visit.

How long does it last?

Typically four to six months. Many people find that with regular treatments they can go longer between visits.

Can I combine it with other treatments?

Yes. Many clients pair it with Botox® for forehead and frown lines, or with chin and jawline filler to refine the profile. Men often add jawline filler for men.
