What is Face Slimming?
Face slimming (masseter slimming) uses targeted injections to reduce activity in the masseter muscles, which can become enlarged through clenching, grinding, or habitual chewing. When these muscles are overactive or bulky, they can widen the lower face and create a more angular or square jawline. Reducing muscle activity allows the area to gradually appear slimmer and more refined over time.
​
During your consultation, the practitioner will assess the size and strength of the masseter muscles, review clenching habits, evaluate facial proportions, and determine whether muscle‑relaxing injections are appropriate. The treatment itself involves a series of small injections placed directly into the masseter muscles, guided by palpation and clench testing to map the muscle borders. The procedure is typically brief and well‑tolerated, with most people returning to normal activities shortly after.
Who is this treatment suitable for?
Face slimming may be considered by adults who feel their jawline appears wide, square, or overly muscular due to enlarged masseter muscles. It may also be considered by individuals experiencing jaw tension or clenching. Suitability can only be confirmed following a comprehensive consultation with a qualified practitioner, which includes assessment of muscle bulk, facial structure, medical history, and individual goals.
Â
A personalised consultation is required to confirm whether this treatment is appropriate and safe for you, taking into account:
-
Masseter size, symmetry, and clenching patterns
-
Facial proportions and cheek volume
-
Medical history and current medications
-
Individual expectations and reasons for seeking treatment
Results, timing and downtime
Responses to face slimming vary between individuals. Early softening may be noticed within 2–4 weeks, with more visible contour changes typically developing over 4–6 weeks as the muscle gradually reduces in bulk. Â
Downtime is usually minimal, though temporary tenderness, chewing fatigue, or mild local effects may occur.
Individual results cannot be guaranteed.
Risks and considerations
All medical and cosmetic procedures carry risks. These will be discussed during your consultation to support informed consent.
Â
Potential considerations may include:
-
Temporary discomfort, swelling, or bruising
-
Mild chewing fatigue, especially with firm foods
-
Asymmetry or subtle changes in smile dynamics
-
The possibility that further treatment or no treatment may be recommended
-
Variability in individual response
Â
Less common considerations include over‑reduction of the muscle, which may accentuate cheek hollowing in predisposed individuals.
Aftercare
Aftercare instructions will be provided by your practitioner and should be followed as advised. These may include avoiding excessive chewing immediately after treatment, refraining from massaging the area, and monitoring for any unexpected symptoms. You should contact your practitioner or seek medical advice if you experience concerning effects following treatment.
