You have buccal fat that should be addressed but yes botox can help slim the jawline if you are a candidate. Best, Dr. Emer.

Botox can be a great option for reducing masseter muscle hypertrophy and in patients that grind their teeth.  Keep in mind that results from this procedure take time due to the decreased tone of the muscle.   Best results are several months after the procedure and after multiple treatments.  Make sure to have a consultation with an expert in facial injectables to accurately diagnose your asymmetry.
