Masseter Botox® in Manchester
Masseter Botox®
Do you wake up with jaw soreness or tension headaches? Fenix’s Masseter Botox® Treatments offer a non-surgical solution for facial pain and aesthetics.
The masseter is a strong chewing muscle on the lower jaw. Genetics, stress, or clenching can cause it to enlarge. By injecting micro-doses of Botulinum Toxin into the masseter, we relax the muscle, easing joint strain and gradually reducing its volume for a slimmer facial shape.

How it works
How Masseter Botox® Works
When the masseter muscle is overused, constant heavy contraction builds up muscle fiber volume, widening the lower third of the face.
The Targeted Biological Process:
-
Nerve Signal Interception: Micro-injections temporarily block acetylcholine release, reducing the intensity of involuntary muscle contractions.
-
Therapeutic Tension Release: As the high-pressure tension subsides, strain on the temporomandibular joint (TMJ), jaw soreness, and associated tension headaches decrease significantly.
-
Gradual Muscle Atrophy: Without constant heavy overworking, the muscle mass shrinks over a period of weeks (disuse atrophy), narrowing the lower face width without altering your natural ability to chew normally.
Areas Treated
Key Target Concerns & Benefits
Jaw Clenching & Morning Soreness
Reduces pain in the jaw joints, temples, and cheek muscles upon waking.
Tension Headaches & TMJ Discomfort
Relieves radiating head and neck tension caused by persistent jaw clenching.
The Process
Your Treatment Journey Expectations
-
Facial Diagnostic & Consultation
Our practitioner evaluates your jaw mechanics, palpates the masseter muscle strength under teeth clenching, and calculates the exact dosage needed per side (typically 25–30 units per side).
-
Mapping & Cleansing
The target injection points are marked out within a safe anatomical boundary (to protect surrounding facial expression muscles) and disinfected with clinical antiseptic.
-
Precision Injections
Using a fine micro-needle, precise doses are administered into 2 to 3 strategic points within each masseter muscle. The process takes less than 15 minutes.
-
Post-Care Briefing
Aftercare guidelines are provided to ensure optimal absorption and prevent product diffusion.

Aftercare
Recovery & Essential Aftercare Guidelines
To maximize your results and maintain a smooth recovery:
Remain Upright for 4 Hours
Avoid lying down or sleeping immediately post-injection to prevent product migration.
Do Not Rub or Massage the Jaw
Refrain from facial massages, firm pressing, or foam rolling the lower cheeks for 24 hours.
Avoid High Heat & Strenuous Workouts
Skip saunas, hot tubs, steam rooms, and intense gym sessions for 24 hours.
Avoid Excessively Hard Foods
Stick to soft foods for the first day; avoid tough, chewy foods after treatment.
Side Effects
Potential Side Effects & Safety Considerations
Masseter Botox® has an excellent safety record when administered by qualified medical practitioners. Normal, short-term responses include:
-
Mild tenderness or a dull ache at the jaw injection sites for 24–48 hours.
-
Minor local swelling or occasional pinpoint bruising.
-
Temporary mild chewing fatigue when eating tough foods during the first 1–2 weeks as the muscle adjusts.

FAQ
Frequently Asked Questions
Between 15 and 30 minutes for the appointment; the injections themselves take under 15 minutes, into 2 to 3 points within each masseter.
A fine micro-needle is used, and the points are mapped and disinfected first. Expect mild tenderness or a dull ache at the injection sites for 24 to 48 hours afterwards.
Jaw tension and the headaches that come with it ease first. The slimming follows the muscle: without constant heavy overworking it shrinks over a period of weeks.
The block on the nerve signal is temporary, so the effect wears off and the treatment is repeated. Your dosing is set at the consultation — typically 25 to 30 units per side.
Yes. It treats the lower third of the face and pairs with the treatments listed below; the placement targets only the deep masseter fibres, so nothing else is affected.
Mild tenderness or a dull ache at the injection sites for 24 to 48 hours, minor local swelling or occasional pinpoint bruising, and mild chewing fatigue on tough foods for the first week or two.
No. The injection points are mapped inside a safe anatomical boundary that protects the surrounding expression muscles, and the muscle narrows without altering your natural ability to chew.
Stay upright for four hours and leave the jaw alone — no rubbing, massage or firm pressure on the lower cheeks — for 24 hours. Light makeup can go on once that has passed.
Tell your practitioner if you are pregnant or breastfeeding, have an active skin infection near the jaw, or have a neuromuscular condition such as Myasthenia Gravis — each of those rules the treatment out.
It suits anyone with bruxism, jaw clenching, TMJ soreness or a wide lower face they want softened. The exclusions are pregnancy and breastfeeding, an active skin infection at the injection sites, and specific neuromuscular conditions.
