Botox for a Slimmer Jawline Benefits, Drawbacks, and Who Should Get It

Home » Botox for a Slimmer Jawline Benefits, Drawbacks, and Who Should Get It

For many people, a chiseled jawline is a key aesthetic feature. But what if you were born with a wider jawline, or teeth grinding has caused your masseter muscles to enlarge over time? In these cases, jaw botox might be a solution.

Jaw botox involves injecting botulinum toxin into the masseter muscle, located on the lower sides of the face. This muscle is responsible for chewing, and when enlarged, it can create a squarer jawline.

Botox relaxes the muscle, allowing it to atrophy (shrink) over time. This can result in a slimmer, more V-shaped jawline.

So, is jaw botox right for you? Here are some things to consider:


  • Non-surgical: Unlike procedures that involve removing parts of the jawbone, jaw botox is a minimally invasive treatment.
  • Reduced jaw clenching: If you grind your teeth or clench your jaw, jaw botox can alleviate these symptoms and any associated pain.
  • Facial slimming: The main cosmetic benefit is a slimmer, more defined jawline. This can create a more balanced and harmonious appearance, especially for those with wider jawlines.


  • Cost: Because the masseter muscle is strong, multiple botox units may be needed, making the treatment more expensive than botox used in other areas of the face.
  • Temporary results: Jaw botox typically lasts for 6 to 9 months, so repeat treatments are necessary to maintain results.
  • Potential side effects: While uncommon, some people experience temporary weakness when chewing after jaw botox. In rare cases, overly rapid muscle atrophy can lead to sagging or jowling, which can be addressed with fillers.

Who is a good candidate?

If you have a wide jawline due to enlarged masseter muscles and are looking for a non-surgical solution, jaw botox could be a good option. It can also be beneficial for those who clench their jaw or grind their teeth. However, if your jaw width is due to your bone structure, jaw botox won’t be effective. A consultation with a qualified medical professional can help you determine if you’re a good candidate for jaw botox and discuss your desired outcome.
