Most people searching for masseter Botox in Toronto are looking for one of three things: a softer, less square jawline; improved facial symmetry; or both. The masseter is the thick muscle at the corner of your jaw that does the work of chewing. I will assess yours at your consultation and explain honestly what treatment can and cannot do.
At Toronto Beauty Nurse, I use Dysport for this treatment. It is my preferred product for the masseter, based on my clinical training. A consultation is required before your first treatment.

The appointment itself is brief. After your assessment, I mark the injection points and treat each side of the jaw with a series of small injections into the body of the masseter. I will talk you through what to expect, including comfort, at your consultation.
The whole treatment takes about fifteen to twenty minutes. You can return to your normal day immediately afterwards.

Whether this treatment suits you is decided at a consultation.
It is worth knowing that this is not a weight-loss treatment and it does not change bone structure — it reduces muscle bulk only. For patients whose wide jaw is primarily skeletal, I will tell you honestly at consultation that the effect will be limited, rather than oversell a result that is not achievable.
There are some situations where I would not treat. Pregnancy and breastfeeding are absolute contraindications. Active infection or skin breakdown at the injection site requires deferral. A small number of people have neuromuscular conditions that affect how neuromodulators work, and anyone with a known hypersensitivity to Dysport or its components should not receive treatment.
GOOD CANDIDATES: wide or square jaw (muscle-related), visible masseter enlargement, facial asymmetry
HONEST LIMIT: does not change bone — skeletal jaw width is not addressable
NOT SUITABLE: pregnancy, breastfeeding, active infection, relevant neuromuscular conditions
CONSULTATION REQUIRED: always, before first treatment
I will go over aftercare with you before you leave, including a few simple things to keep in mind in the first four hours after treatment.
Avoid lying flat, doing strenuous exercise, or applying heat (saunas, hot yoga) for four hours post-treatment. Do not massage or press firmly on the injection sites. These precautions help keep the product localised to the masseter and reduce the small theoretical risk of it migrating to nearby muscles.
Side effects are possible with any treatment. I will go over them with you at your consultation and check how you have responded at your follow-up.
I will book a follow-up with you so I can assess your response, check symmetry, and plan your next session if needed.
FIRST 4 HOURS: no lying flat, no exercise, no heat, no massage at injection sites
BRUISING: possible, resolves within a few days
SIDE EFFECTS: reviewed at your consultation
FOLLOW-UP: booked with you after treatment
