Treatment for Muscle-Related Concerns

Medical Anti-wrinkle injections is used to reduce targeted muscle activity for selected clinical indications, including jaw clenching (Masseter), shoulder and neck tension (Trapezius), and chronic migraine. It is a prescription-only medicine, and suitability is always determined by individual clinical assessment at Orovenza, part of Contoura Medical.

The service can include treatment pathways involving the Masseter, Trapezius or migraine indication, subject to clinical assessment, and is prescribed and administered under Dr Edwin Anthony’s medical direction.

Medical anti-wrinkle injections use the same prescription-only medicine as cosmetic anti-wrinkle treatment to relax overactive muscles. At Orovenza in Marylebone, they are offered for jaw clenching and teeth grinding, jaw slimming, trapezius tension and contour, and selected migraine cases after full assessment.

What it is and how it works

Medical anti-wrinkle injections are small, measured doses of a prescription-only medicine placed into a specific muscle. The medicine reduces the nerve signal that tells the muscle to contract, so the muscle works less hard for a period of months. The effect wears off gradually as nerve signalling returns.

The difference from cosmetic treatment is the target. Instead of softening lines on the forehead, we treat muscles that cause symptoms or bulk: the masseter at the angle of the jaw, the upper trapezius between the neck and shoulder, and, for a small number of carefully selected patients, the pattern of head and neck muscles used in chronic migraine protocols.

Every treatment is prescribed by Dr Edwin Anthony (GMC 4776646), Lead Clinician at Contoura Medical, after a face-to-face consultation. The injections are then given by Nurse Rashmi Mehta, our Aesthetic Nurse, at Langham Hospital.

Who it is best suited for

  • Adults who clench or grind their teeth, often waking with a tight jaw, worn teeth or a tension headache around the temples.
  • People with a square or heavy lower face caused by an enlarged masseter muscle, who would like a softer jawline.
  • Those with a bulky, constantly tight upper trapezius that gives a hunched outline or a sense of shoulder and neck strain.
  • Adults already diagnosed with chronic migraine, where assessment suggests this approach is appropriate and we can work alongside their GP or neurologist.

Your treatment journey at Orovenza

  1. Consultation: a face-to-face appointment with Dr Anthony covering your symptoms, medical history, medicines and goals. For migraine we also ask about your diagnosis and previous treatments.
  2. Plan: if treatment is suitable, you receive a written plan covering the muscles to be treated, the expected timeline and your personal cost.
  3. Treatment day: Nurse Rashmi cleans the skin, marks the injection points and uses a very fine needle. Most appointments take 15 to 30 minutes.
  4. Aftercare: you leave with written aftercare guidance and a direct number to call with any concerns.
  5. Review: a review appointment lets us check the effect, fine-tune if needed and record your response to guide future timing.

Results and how long they last

Results build slowly. Clenching often eases within one to two weeks, while visible jaw slimming takes longer because the muscle has to reduce in size. A prospective study of 24 adults in BMC Oral Health found the greatest reduction in lower face volume at week 12, with median satisfaction scores on the FACE-Q scale rising from 34 to 66 and self-reported chewing function staying stable.

For migraine, NICE guidance TA260 sets clear limits. It applies to adults with headaches on at least 15 days a month, at least 8 of which are migraine, who have not responded to at least three preventive medicines. NICE advises stopping if headache days fall by less than 30% after two treatment cycles, which is why we review migraine patients closely and share findings with their doctor.

Recovery and aftercare

  • Most people return to work straight away; small marks at the injection points settle within an hour.
  • Avoid rubbing or massaging the treated area for the rest of the day.
  • Skip strenuous exercise, saunas and alcohol for 24 hours.
  • For masseter treatment, chewing tough foods may feel tiring for a week or two as the muscle adjusts.
  • For trapezius treatment, keep heavy lifting and intensive upper body training light for a few days.

Safety, side effects and who should avoid it

  • Common, short-lived effects include tenderness, mild swelling, bruising and a brief headache.
  • Masseter treatment can make chewing feel weaker at first, and rarely affects the smile if the medicine spreads.
  • After trapezius treatment some people notice heaviness or weakness; a review in Archives of Plastic Surgery reports this discomfort typically resolving within two months.
  • Treatment is not suitable in pregnancy or breastfeeding, with certain neuromuscular conditions, with infection at the injection site, or with known sensitivity to the medicine.
  • We never treat anyone under 18, and the JCCP advises a face-to-face consultation with a prescriber before this type of treatment, which is our standard.

Frequently asked questions

Can anti-wrinkle injections help with jaw clenching and teeth grinding?

Yes, for many people. Relaxing the masseter reduces the force behind clenching and grinding, which can ease jaw ache and morning tension headaches. It does not treat the cause, such as stress, so a dental night splint is often still worthwhile.

Will masseter injections make my face look slimmer?

They can, if a large masseter is the reason your jaw looks wide. The muscle shrinks slowly, so slimming appears over several weeks rather than days. If your jaw width comes from bone or fat instead, Dr Anthony will tell you honestly at consultation.

What is trapezius treatment and who is it for?

It is treatment of the upper trapezius, the muscle running from your neck to your shoulder. It suits people with a constantly tight, bulky trapezius who want less tension or a longer looking neckline. It is not a replacement for physiotherapy, so persistent neck pain should also be assessed by your GP or a physiotherapist.

Can I have anti-wrinkle injections for migraine privately?

Possibly, but only after full assessment. We need a confirmed chronic migraine diagnosis and details of treatments you have tried. Where appropriate we work with your GP or neurologist, using NICE guidance TA260 as a reference for who is likely to benefit and when treatment should stop.

Does the treatment hurt?

Most patients describe a quick pinch at each point. We use a very fine needle, and the whole appointment usually takes under half an hour. The masseter can feel a little tender afterwards, and the trapezius may ache briefly. Numbing cream is rarely needed, but we can offer it.

How soon will I notice a difference?

Muscle relaxation usually starts within a few days and settles over about two weeks. Easing of clenching or trapezius tension is often felt first. Visible jaw slimming takes longer, with research showing the largest change around week 12. Your review appointment is timed so we can judge the effect properly.

How long do the results last?

The effect is temporary and usually lasts several months before the muscle gradually returns to normal. How long depends on your muscle strength, metabolism and how hard you clench. Your review helps us plan sensible timing for any repeat treatment.

What affects the cost of medical anti-wrinkle injections?

The main factors are the area treated, the amount of medicine needed and whether one or both sides are treated. Your personal cost is confirmed in writing at consultation, and the fixed consultation fee is separate from the treatment price.

Is it safe, and who prescribes it?

When prescribed after proper assessment and given by a trained practitioner, it has a well established safety record. Dr Edwin Anthony (GMC 4776646) prescribes every treatment after meeting you face to face, and Nurse Rashmi Mehta administers it in a hospital setting. Side effects are usually mild and temporary, such as tenderness or bruising.

Can I combine medical and cosmetic anti-wrinkle treatment?

Yes, many patients have masseter treatment alongside forehead or frown line treatment in the same appointment. Dr Anthony plans the total dose across all areas so it stays within safe limits. Other injectables, such as Profhilo, are usually spaced a week or two apart.
