Most patients return to daily activities immediately after the procedure. We usually recommend avoiding intense exercise lying flat or massaging the treated area for several hours. Minor redness or swelling at injection sites generally resolves quickly. Detailed aftercare instructions are provided at your appointment.

Jaw slimming with neuromodulators works gradually. Unlike wrinkle treatments where results can be seen within days muscle contouring changes take longer to appear.

Typical timeline

Early changes in muscle relaxation may begin within a couple of weeks
Visible slimming of the lower face usually appears progressively over 1 to 3 months
Maximum effect is often seen after several weeks as the muscle becomes less bulky
Results then slowly diminish as the product wears off over several months

Because this is a progressive treatment some patients choose a series of sessions to reach and maintain their desired level of slimming. Dr Mansour will discuss an individualized plan based on your anatomy and response.

You may be a candidate for jaw slimming treatment in Montreal if

You feel your jawline looks wide or square and this is due mainly to strong chewing muscles
You would like a slimmer lower face without surgery
You are in good general health and not pregnant or breastfeeding
You are willing to have a medical assessment of your bite jaw function and habits
You have realistic expectations about the degree of change and the gradual nature of results

Jaw slimming injections are not appropriate for everyone. If your jaw shape is mainly due to bone structure or skin laxity other options or referrals may be recommended. During your consultation we will clearly explain whether this treatment is likely to benefit you.

Many patients see a noticeable difference after the first treatment once the muscles have had time to respond. However because we follow a conservative approach some people choose additional sessions to refine and maintain their results. The exact number and spacing of treatments will be discussed with you individually.

Jaw slimming with neuromodulators is a medical procedure that should only be performed by trained professionals familiar with facial anatomy and function. At our Montreal clinic safety and conservative dosing are priorities.

Common temporary effects may include

Mild redness or swelling at injection sites
Small bruising in the treated area
Sensation of tiredness or mild discomfort in the jaw muscles
Temporary changes in chewing strength as the muscles relax

Less common but more significant risks and contraindications are reviewed in detail during your consultation. You will receive clear pre and post treatment instructions and we encourage you to contact the clinic with any concerns following your procedure.

Jaw slimming injections focus specifically on reducing the prominence of overactive masseter muscles. Depending on your goals they may be combined with other aesthetic treatments such as

Dermal fillers
To refine the chin or jawline contours or balance facial proportions in the profile view

Skin and collagen treatments
Such as microneedling or PRP to improve overall skin quality and firmness in the lower face

Facials and medical skincare
To support healthier brighter skin and complement changes in facial shape

At your Montreal consultation Dr Mansour can design a step by step plan that may include jaw slimming along with other non surgical options when appropriate.

Neuromodulator injections in the masseter muscles are carefully dosed to reduce excessive muscle bulk while maintaining normal function. Some patients notice a temporary change in chewing strength especially in the first weeks after treatment but most adapt quickly. Your medical evaluation will include a discussion of your chewing habits and any history of jaw issues so we can plan a safe approach.

Unfortunately, as a doctor under the Régie de l'assurance maladie du Québec (RAMQ), we are unable to provide receipts for private insurance purposes.

Once achieved jaw slimming results can last several months. Over time the effect gradually wears off as the neuromodulator is metabolized and muscle activity returns. Some patients notice that repeated treatments help maintain a slimmer contour with less product as the muscles adapt. Duration and maintenance plans vary by individual.

Jaw slimming injections in our Montreal clinic target the masseter muscles at the back of the jaw. By gradually reducing the bulk of these muscles, the lower face can appear slimmer and less square in suitable candidates.

Yes. For patients whose wide jawline is mainly due to strong chewing muscles, non surgical jaw slimming can refine the lower face and enhance jawline definition without surgery.

We offer non surgical jawline slimming at our Montreal clinic using neuromodulator injections into the masseter muscles after a full assessment of your bite, facial proportions and muscle activity.

By relaxing the overactive masseter muscles over time, lower face slimming treatments in our Montreal clinic can decrease muscle volume, helping the jawline look softer and more tapered while maintaining normal chewing function.
