Can Botox Be Used for Jaw Reduction?

Doctor Answers (8)


In a single treatment that takes no more than 15 minutes, your jawline can be gently reshaped to make it less angular and prominent, narrowing the contour of your lower face to create a more feminine appearance. A few units of Botox injected directly into the jaw muscle responsible for chewing, known as the masseter, is all that it takes. Treatment will selectively relax the masseter in the days following your injection, gradually making it less prominent and square. The width of your jawline will slowly narrow, transforming your facial shape into more of an oval or heart. Optimal results may take up to four to six weeks to appear, but can last for up to a year depending on lifestyle habits. To maintain results, you’ll need touch-up injections most likely scheduled twice a year.

Botox is a reasonable approach in reducing appearance of jaws.


Depending on the opinion of your plastic surgeon, you may be a good candidate for Botox to reduce the appearance of the jowl area.  Botox to the masseter muscle is reportedly performed to reduce the appearance of the jaws. The masseter is quite a large and strong muscle. Partial paresis of the muscle may result in other portions bulging. This seems entirely possible and can easily be remedied with additional Botox as advised. This seems reasonable given the size of the muscle.

Schedule a consultation with a PS.

Botox and cheeks/ jaw


If someone has a round face from the hypertrophy of the masseter (Chewing) mucscle, the lower cheek will be enlarged from this growth. Botrox can miinimze the activity of this muscle ofn relax its contour.

Botoxs can be used to narrow the jawline if the masseter muscle is hypertrophic.  This would take several treatments over at least a years period before results would be perceivable.

Botox be used for jaw reduction


Yes it can be used but it is a very risky procedure and the "thinning" of the masseter muscle is very unpredictable. Be very careful.

Botox for "jaw reduction"


If by "jaw reduction" you mean to narrow the appearance of the jawline, then yes.  Treatment typically requires a few sessions involving injection of Botox into the masseter muscles which account for the bulky appearance of the jawline in some women.  I would seek the care of an experienced cosmetic physician.

Good luck.

Jaw reduction and botox


Botox can be used for injection to the masseter muscle, a large muscle that closes the jaw.  Some patients may have masseter hypertrophy, or an enlarged muscle which makes the jaw look wide and widens the face.  Botox will weaken this muscle and make it somewhat smaller.  This may help the appearance of the jaw region.  There are other muscles used for closing the jaw so botox injection to the masseter should not effect chewing significantly.

Botox and the Jaw


Botox is not used for jaw reduction. Botox temporarily relaxes or paralyzes muscles that are responsible for certain facial wrinkles. The effect is to minimize the appearance of those particular wrinkles.
