I've heard that Botox can also be injected on the chewing muscles in the mouth to help to create a thinner-looking face. Is this true?
Can Botox Create a Thinner-looking Face?

Great for relief of Migraines, as well!
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 smaller, only for those with prominent masseter muscles that define the shape of their face.
The real use for injecting Botox into this muscle is to relieve muscle tension or migraine headaches. I am told that for those with uncontrollable headaches, that this has some benefit.
In a word, yes
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 angular and feminine facial shape. This effect can be further enhanced by filling the cheek bone area with facial fillers. For better or worse, the effects of Botox injections are temporary and non cumulative, meaning they will not add up if repeated several times. So, you would need to repeat the injections every 3-6 months to maintain the effect. Good luck!
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 is realized by the FDA as an “off-labeled use”; thus, it should be performed by someone experienced because of potential and unwanted adverse effects. I have injected this muscle a few times in my career, following dental procedures for the treament of muscle spasm. I will purposefully start with a small dose and work upwards. In general, I must warn you to be be careful.
A much safer route is to use Botox in conjunction with facial fillers and/or skin resurfacing. Botox has found a defined role in restoring facial harmony by removing unwanted lines and wrinkles in areas such as: between the head of the eyebrows (glabella), the forehead, and around the eyes (crow’s feet). Also, Botox can elevate the corners of the mouth and soften the vertical lines of the upper lip. Soft tissue filler injections can powerfully make the face appear thinner by adding volume to the cheeks, contouring the jaw line, and soften major and minor facial wrinkle lines, etc. A combination approach is the way to go!
I hope this information is helpful.

Yes, Botox can be used on the masseter muscles
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.

Botox to the MASSETER MUSCLE to thin the lower face
Botox is used to shrink the master muscle and this can thin the face. This is a specialized treatment so use an expert injector.

Botox to thin the face
The injection technique does vary by physical exam and the goals of the treatment. Facial contouring goals may change the injection sites themselves to affect different portions of the masseter as well as the dose. The strength of the masseters can be felt by palpation and also helps me to determine dosing. In general, I start with 15- 25 units per side for most patients. If the have very strong masseters, then I may increase the dose, but more commonly ask them to return in three weeks for a touch up. Once you get the desired result, I let patients know that future treatments may require less to maintain the look or the jaw clenching symptoms, especially if they get treated as soon as they notice the symptoms return.
Botox for a thinner looking face
This is a common question I see in my office, especially from Asian patients who tend to have more rounded facial features.
Botox or Xeomin are very useful when injected into one of the muscles of chewing called the masseter muscle. I generally use a series of 2-3 injections of 20 units to each side. After several months, noticeable slimming of the jawline can be appreciated.
The only FDA indications for Botox are the lines between the eyes and the crow's feet. This type of injection is considered off-label.
For this reason, make certain you see a doctor who has extensive experience injecting Botox before you proceed. I would not recommend seeking this type of treatment from a spa.
I hope this helps. Best wishes, Dr. S
