Several months; not permanent

Masseter and Lower Face Procedure Information
Treatment Areas
- Lower face and jawline
- The chewing (masseter) muscles
- Concerns about jawline contour and facial balance or symmetry
Common Names
- Masseter treatment
- Lower-face or jawline contouring
- Facial slimming (a common lay term for the concern)
MOA
At a consultation a practitioner examines the lower face and assesses the size and activity of the chewing (masseter) muscles, along with other factors that can influence jawline shape — such as bone structure, facial fat and the salivary glands. Not everyone with a fuller or squarer jawline is suitable, because the underlying cause differs from person to person and is assessed individually. If an injectable treatment is considered appropriate, the practitioner explains in general terms how it works to reduce muscle activity, together with its benefits, limitations and risks. The specific medicines used are prescription-only, so by law we can’t name them, their doses or their prices in public information — these are discussed with you in person.
Masseter and Lower Face Treatment Summary
Number of Treatments
The number of sessions varies for each person and is determined at your consultation. Some people choose repeat sessions as part of an ongoing plan.
Procedure Time
Procedure time is determined during your consultation and varies for each person.
Discomfort Level
A topical numbing cream or other comfort measure may be applied, and most people describe the sensation as brief and tolerable. Discomfort varies between patients, and comfort options are discussed with you at your consultation.
Recovery Time
Any downtime is usually short, though mild, temporary redness or swelling can occur at the injection site.
Results
Changes to the appearance of the treated area develop gradually rather than immediately, and both the onset and degree of change vary between individuals.
Duration of Results
The effect is not permanent and typically wears off over a number of months, with the timeframe varying between individuals.
Resumption of Usual Activities
Most people return to their usual activities soon after treatment; your clinician will advise on anything to avoid.
Aftercare
Your clinician provides individualised aftercare advice following your treatment.
Masseter and Lower Face General Information
Process
Every treatment begins with a thorough consultation. Your clinician assesses your facial structure and muscle activity and considers other factors that can affect jawline shape before determining whether the procedure is appropriate for you. A fuller jawline can be caused by muscle activity, but also by bone structure, facial fat or the salivary glands, so careful assessment matters and not every person is suitable.
How to Choose Your Masseter and Lower Face Treatment Provider
A fuller or squarer jawline has several possible causes — muscle activity, bone structure, facial fat or the salivary glands — so the first thing a good provider does is work out what is actually driving yours. Choose a practitioner who examines the lower face and assesses masseter activity in person, and who is honest that this treatment only helps when muscle bulk is the cause and isn’t right for everyone. Because it uses a prescription-only medicine, an authorised prescriber should be involved. Ask how they guard against and manage asymmetry or a temporary change to your smile or chewing, and expect them to explain that any change develops gradually over weeks rather than immediately.

- Includes an open discussion of benefits, limitations, gradual timeframes, risks and alternatives
- Carried out ethically, with no pressure and no treatment offered where it isn’t appropriate

Frequently asked questions
Is this treatment suitable for everyone?
No. Suitability depends on factors such as your facial anatomy, muscle strength and overall health, and the cause of a fuller jawline differs between people. Your clinician confirms whether it is appropriate for you following a full consultation.
When might I notice a change, and how long does it last?
Changes to the appearance of the treated area develop gradually rather than immediately, and both the onset and how long the effect lasts vary between individuals. Your practitioner will explain what to expect and whether a review appointment is needed.
Is it painful?
Discomfort varies from person to person. A topical numbing cream or other comfort measures may be used, and pain management is discussed with you before treatment.
What are the risks?
As with any cosmetic procedure there are risks, including swelling, bruising, tenderness, asymmetry and, less commonly, a temporary effect on facial movement. These are discussed in full at your consultation and on our Risks & Complications page.
Are there other options?
Yes. This is one option among several, and it is not suitable for everyone. Your clinician will discuss alternatives with you and help you make an informed decision.
