A: Botox can make jaw look less square.

George J. Beraka, MD

Very hard to answer this question without examining you. If you think your lower face looks too wide  AND  if this excess width is due to overgrown masseter ( chewing )muscles, then very precisely placed Botox injections will help. This treatment requires a fair amount of Botox, which makes it more... more

A: In a word, yes

Kenneth R. Francis, MD

The masseter muscle, one of the chewing muscles, is sometimes enlarged causing a squaring of the facial shape.  It occurs most often in those of Asian heritage and can be helped by Botox injections.  Botox will cause some shrinkage of the muscle and narrow the jaw, creating a more... more

A: Yes, Botox can assist in making the face appear thinner, especially with use of soft tissue fillers.

Botox certainly can assist both directly and indirectly in making the face appear thinner. Direct injection into one of the major muscles of the jaw that is used for chewing (mastication) has been reported to assist in making the lower third of the face appear thinner.  However, an injection of this type... more

Yes, Botox has been used and described in the literature to thin the face by slightly paralyzing the masseter muscle that allows you to chew food.  This will thin out the jawline in patients that have a hyperactive masseter muscle and seem very wide in the lower jaw region that is not the result of the... more

A: Great for relief of Migraines, as well!

Robert M. Freund, MD

Injecting Botox into any muscle causes the muscle to stop working and shrink in size. We use this knowledge to make patients wrinkle-free. Injecting Botox into the chewing muscle (masseter muscle) will cause it to get smaller and the lower face will appear thinner. It is not used to make a round or chubby face... more

A: Yes, Botox can be used on the masseter muscles

David Shafer, MD

CS, It is possible to inject Botox into the masseter muscles to help thin the face. However, you should be sure that you are being injected by someone with extensive experience in Botox injection. It is not standard practice to use Botox in this way, but it can be done. I hope this is helpful. David Shafer... more
