Jaw Defining

A non-surgical treatment that relaxes the jaw muscle to gradually reduce its size, creating a slimmer, more defined profile.

Treatment

Small doses are administered into the masseter muscle to relax and gradually reduce its size. The procedure typically takes 15–20 minutes.

Frequently Asked Questions

The treatment relaxes the masseter (jaw) muscle, which over time may cause it to reduce in size and slim the jawline for a more contoured appearance. Individual results may vary.

The treatment reduces excess bulk in the muscle but does not typically impair normal chewing function. Your practitioner will discuss this with you during your consultation.

Results typically last 4–6 months. With regular treatments, the muscle may remain slimmer for longer periods. Your practitioner will recommend a maintenance plan.
Many clients report relief from bruxism symptoms as a secondary benefit of this treatment. However, outcomes vary and this should be discussed during your consultation.
Most clients see results after 2–3 sessions spaced a few months apart. Maintenance is typically every 6–12 months.

All treatments are performed by qualified, AHPRA-registered practitioners with advanced training in cosmetic injectables.
