Many London practices offer treatment packages providing better value for patients seeking comprehensive facial contouring with regular maintenance protocols.
Before and After Botox for Jaw Slimming Treatment
Patients experience gradual yet noticeable changes in facial contours following masseter muscle relaxation. The progressive muscle atrophy creates subtle refinements in jaw definition, resulting in:
- Visible reduction in lower face width becoming apparent within 4-6 weeks post-treatment
- Softened jawline angles creating more feminine or refined facial proportions
- Improved facial symmetry through balanced masseter muscle reduction
- Enhanced cheekbone prominence as jaw width decreases and upper facial features become more apparent
- Reduced muscle tension and bulging during jaw clenching or teeth grinding
- More defined transition between jaw and neck contours
- Overall facial harmony improvement through proportional lower face refinement
Initial changes typically manifest within 2-3 weeks as muscle relaxation begins, with optimal contouring effects achieved by 6-8 weeks post-injection. The gradual nature of results ensures natural-appearing facial transformation without dramatic overnight changes. Patients frequently report enhanced facial confidence as their profile becomes more refined and proportionate, achieving subtle improvements that complement existing facial features.

What is Botox for Jaw Slimming?
Botulinum toxin jaw slimming involves strategic injection of neurotoxin into hypertrophic masseter muscles to reduce their volume and prominent appearance. This therapeutic approach utilises the muscle-weakening properties of botulinum toxin to create controlled atrophy in overactive or enlarged chewing muscles.
The masseter muscles, responsible for jaw closure and chewing force generation, can become enlarged through genetics, bruxism, or habitual jaw clenching behaviours. Botulinum toxin temporarily blocks acetylcholine release at neuromuscular junctions, reducing muscle contractile ability and subsequent bulk over time.
Clinical mechanisms of jaw slimming treatment include:
- Selective denervation of masseter muscle motor units
- Gradual reduction in muscle fibre size through disuse atrophy
- Decreased muscle tension and hyperactivity patterns
- Preservation of essential chewing function whilst reducing bulk
- Temporary interruption of muscle memory patterns contributing to enlargement
- Progressive facial contour refinement through controlled muscle volume reduction
The treatment requires precise anatomical knowledge to target appropriate muscle regions whilst avoiding adjacent structures. Skilled practitioners understand masseter muscle anatomy variations and individual facial proportions necessary for achieving harmonious results without compromising essential jaw function or creating asymmetrical outcomes.
Botox for Jaw Slimming Process: Step by Step
Our comprehensive jaw slimming protocol ensures safe and effective masseter muscle reduction through systematic medical assessment and precise injection techniques:
- Detailed Facial Assessment: Comprehensive evaluation of jaw proportions, masseter muscle size, and overall facial harmony analysis
- Muscle Function Analysis: Assessment of chewing patterns, bruxism signs, and functional jaw movement evaluation
- Anatomical Mapping: Precise identification of masseter muscle boundaries and optimal injection point determination
- Medical History Review: Evaluation of previous treatments, dental work, and conditions affecting jaw function
- Pre-Treatment Photography: Baseline documentation from multiple angles to track treatment progress and outcomes
- Injection Site Preparation: Thorough skin cleansing and optional topical anaesthesia for enhanced patient comfort
- Strategic Botulinum Toxin Administration: Systematic injection delivery using anatomically precise techniques and appropriate unit calculations
- Immediate Assessment: Post-injection evaluation of injection sites and muscle response verification
- Aftercare Instruction Provision: Detailed guidelines for optimal healing and treatment outcome maximisation
Treatment sessions require 20-30 minutes with minimal patient discomfort reported during injection procedures. The outpatient nature allows immediate return to normal activities whilst treatment effects develop gradually over subsequent weeks.

Benefits of Botox for Jaw Slimming
Botulinum toxin jaw slimming offers numerous advantages over surgical jaw reduction approaches through its non-invasive and reversible nature:
Non-Surgical Facial Contouring
Achieves significant jaw width reduction without surgical risks, general anaesthesia, or extended recovery periods associated with mandibular reduction procedures.
Gradual Natural-Appearing Results
Progressive muscle atrophy creates subtle facial changes that appear naturally evolved rather than dramatically altered through medical intervention.
Functional Benefit Integration
Addresses both aesthetic concerns and functional issues such as teeth grinding, jaw tension, and associated headache patterns through muscle relaxation.
Reversible Treatment Outcomes
Temporary effects allow treatment modification or discontinuation based on patient satisfaction and changing aesthetic preferences over time.
Minimal Treatment Downtime
Injection procedures require no recovery period, allowing normal social and professional activities immediately following treatment administration.
Customisable Muscle Reduction
Precise control over treatment extent enables tailored approaches based on individual facial anatomy and desired aesthetic outcomes.
High Safety Profile
Extensive clinical research demonstrates minimal adverse effects when performed by qualified practitioners using appropriate injection techniques and unit calculations.

Frequently Asked Questions
How long do jaw slimming results from botulinum toxin last?
Results typically persist 4-6 months, with some patients experiencing effects lasting up to 8 months. The duration depends on individual muscle metabolism, injection technique precision, and personal physiological factors. Regular maintenance treatments help preserve jaw slimming benefits and prevent masseter muscle re-enlargement over time.
Is botulinum toxin jaw slimming treatment painful or uncomfortable?
Most patients report minimal discomfort during injection procedures, describing brief pinching sensations that resolve immediately. The fine needles used for facial injections create minimal tissue trauma. Some individuals may experience mild tenderness at injection sites for 24-48 hours, which typically resolves without requiring additional treatment.
Who represents an ideal candidate for jaw slimming treatment?
Suitable candidates possess prominent masseter muscles creating a square or wide jaw appearance that affects facial proportion harmony. During consultation, we evaluate muscle size, facial anatomy, functional concerns, and realistic expectations to determine treatment appropriateness and potential outcomes.
How many units of botulinum toxin are needed for effective jaw slimming?
Treatment typically requires 25-40 units per masseter muscle, totalling 50-80 units for bilateral treatment. Precise requirements depend on muscle size, desired reduction degree, and individual anatomical characteristics. Our practitioners calculate optimal unit allocation based on comprehensive facial assessment.
What should I expect during the weeks following jaw slimming treatment?
Initial results become noticeable within 2-3 weeks as muscle relaxation begins. Optimal jaw width reduction typically manifests by 6-8 weeks post-treatment. Some patients experience temporary difficulty with extremely hard foods during the first few weeks as muscle strength gradually decreases. Normal chewing function remains preserved throughout the treatment period.
