Can Masseter Botox Results Be Reversed?

Botox® treatments can be used by experts to create a variety of improvements in facial aesthetics. Treatment of the masseter muscle results in temporary atrophy (shrinkage) of the muscle bulk which can change the perceived width of the lower face. The effects of this treatment wear off after 3 months and the muscle bulk will gradually return.

Botox® effects can not be "reversed" in the short term which means the treatments need to be done very carefully. However, one of the best features of Botox® is that the effects wear off completely after several months. Subsequent treatments can then be tailored to your needs as you mature. If you have had just two treatments over the last three years it is not likely that you have any lasting effect on your facial shape. You should consult with an experienced and qualified Plastic Surgeon to discuss your concerns and to learn about surgical and non-surgical treatment options available.

Masseter BOTOX therapy is transient.  The direct effects last about 4 months.  Muscle retraining effects last a bit longer than this.  However, after about a year, it is highly improbable that any changes in your jaw line that you might perceive will be related to the BOTOX treatment.  Remember though that time alone changes the face.  If you have gained or lost weight, this will have a bearing on how your perceive the face.
