can the face change dramatically if botox injections were used to reduce the jaw and slim the face? does it give similar results to jaw shaving?
Jaw Reduction Using Botox - How Are the Results?

Botox to smooth the jawline contour
Botox is an effective treatment for reducing a prominent, disproportionate, or asymmetric jaw line caused by hypertrophic (enlarged) muscles of mastication. These muscles along the posterior jaw are used to chew and clench the teeth, and are commonly enlarged if you clench or grind your teeth while sleeping. Non-surgical jaw reduction with Botox is a temporary solution for those who would like to smooth a sharp jaw line contour from squared to a more feminine oval shape. The treatment works by reducing the size of the muscles injected, thereby smoothing the facial contour Results may last approximately eight months, which is longer than the average duration for the most commonly treated facial Botox areas (i.e. frown lines, forehead, and crowsfeet, which last an average of three to four months).
It is important to note that this treatment is only effective on patients with enlarged jaw muscles; it will not change a squared jaw line that is defined by a squared jaw bone. If this is the case, surgical intervention would be required. A consultation with your experienced Cosmetic Dermatologist or Board Certified Plastic Surgeon will determine which treatment is appropriate for your particular facial structure.
Yes it can make a difference
Botox is injected into the masseter muscle to induce reduction of movement/size. Bone, skin thickness, fatty tissue are all factors that are assessed prior to treatment. If majority of the bulk along the jawline is the muscle, then their response to a reduction will be large and vice versa. We have seen dramatic results in our practice.
Speak to your practitioner who is experienced with these treatments to see if you are an appropriate candidate. If injected improperly changes in smile and interference in facial expression can be experienced. Appropriate dose is also important when achieving optimal results.
Jaw Reduction Using Botox
Hello and thank you for the question.
Regarding your question, the indications for Botox Cosmetic, although only approved by the FDA for management of glabellar furrows, has gone far beyond the eradication of wrinkles. As an example, in the appropriate patients, Botox Cosmetic can be used quite effectively in facial slimming, and notably jaw slimming. This well described technique is effective in narrowing of the lower facial width in patients with pronounced or hypertrophic masseter muscles. These patients tend to have a square jaw or increased lower facial width. The net result of Botox use in the masseter muscle is a more youthful triangulation of the face better emulating the "triangle of youth".
Additionally, with long-term use of Botox, jaw bone remodeling along the external aspect of the mandibular angle is seen in the relaxed or diminished state of the masseter muscle , manifesting in a thinner jaw bone over time. These treatments are generally completed over 2 to 3 sessions, with follow-up injections every 3 to 6 months.

Thanks for the question,
Botox can give terrific results for jaw reduction. This works by thinning (atrophy) the jaw muscle and lasts about 5 to 7 months. I find that with subsequent treatments patients need a little less Botox than the first treatment of about 50 units. So the second treament may be about 40 units.
A couple of things to look out for:
1. Older patient with full cheeks or jowls may have a little fullness of the jowl around the corners of the mouths may find this looks bigger if the jaw line is reduced.
2. Thin face patients may look even more thin after the treatment.
It works great on the right patients.
Hope that helps.

Muscle reduction with Botox
Yes, you can get some atrophy of muscles with Botox. I have used Botox to decrease the calf muscles but the results are temporary(as long as the Botox works-couple to several months) and a lot of it needs to be used.; It would work the same for any muscle but "shaving" the muscles would be much more effective and longer lasting.
Botox for jaw shaping
Botox and other botulinim toxins can be used to shape the lower part of the face. The muscles targeted are the masseter (chewing) and the Depressor Anguli Oris or marionette line muscle. It cannot reduce jaw size.
The results that can be anticipated with targeting these with Botox or Dysport include:
- Less square shape to lower half of face (very popular in Asia)
- Reduction of downturned mouth appearance.

Botox Jaw Reduction
Botox jaw reduction can reduce the size of the masseter muscle and create a slimmer appearing jawline and face. It is critical that the injector has knowledge of facial anatomy.
Botox can reshape the face safely and impressively
Botox can be safely used to 'slim / thin' the round face if the masseter muscles overlying the jawbone (mandible) are large / thick. An evaluation should be made by your doctor so that you can determine the etiology of your concerns -- whether the bone is wide or whether the muscle is large. Many patients (in particular, Asians) can enjoy a slimmer, oval facial shape with Botox injections to the masseter muscle. The results are subtle but quite impressive. The procedure is safe, affordable, and can be performed in the office in less than 5 minutes. It is absolutely worthwhile to try Botox prior to undergoing a larger facial reshaping procedure (i.e., surgery).
In addition, some patients may wish to consider newer types of minimally invasive surgical procedures such as laser-liposuction to the face. Patients, however, must be carefully evaluated and counseled prior to this type of procedure by a surgeon with ample experience with laser-liposuction.
Yes Botox can make the Jawline appear slimmer
Botox can be safely injected into the muscles along the outer portion of the outer and lower portion of the cheek/jawline region which will give the appearance of a thinner lower face. The bony portion of the jawline is not impacted but the muscles are and that can make the face look much less 'boxy' or 'square' for patients with that concern.
