Botulinum toxin (Botox) for blepharospasm is a 10–15 minute in-clinic treatment in which tiny doses of toxin are injected around the eyes to relax the orbicularis oculi muscles that involuntarily force the eyelids shut. It is the recognised first-line treatment for benign essential blepharospasm and hemifacial spasm. At our partner clinics, treatment starts from £400 per session including the toxin, after a consultant oculoplastic assessment from £200. Relief typically begins within 3–7 days, lasts around 3–4 months, and injections are then repeated to keep symptoms controlled.
What is blepharospasm?
Benign essential blepharospasm is a focal dystonia — a neurological condition in which the muscles around the eyes contract involuntarily. The orbicularis oculi muscle, which normally closes the eyelid for a blink, begins to squeeze repeatedly and forcefully. What can start as increased blinking, light sensitivity or eye irritation progresses to frequent, uncontrollable spasms that can leave a person functionally blind during an attack, even though the eyes themselves are healthy.
A related condition, hemifacial spasm, causes twitching on one side of the face, usually beginning around the eye and spreading to the cheek and mouth; it is most often caused by a blood vessel pressing on the facial nerve. Both conditions respond extremely well to botulinum toxin, which has been the mainstay of treatment for over three decades. Mild, occasional eyelid twitching (myokymia) — the harmless flutter most people experience when tired or stressed — is different and rarely needs treatment.
Symptoms that respond to treatment
- Involuntary forceful eyelid closure — spasms that clamp the eyes shut
- Increased blinking that you cannot control or suppress
- Light sensitivity (photophobia) triggering or worsening spasms
- Functional blindness during attacks despite healthy eyes
- One-sided facial twitching spreading from the eye (hemifacial spasm)
- Difficulty driving, reading or working because of eye closure
Recognise these symptoms? A consultant oculoplastic assessment confirms the diagnosis, excludes other causes and plans a tailored injection map for your pattern of spasm.

Botulinum toxin is the established first-line treatment for blepharospasm and hemifacial spasm, recommended because it is effective, targeted and reversible. Your consultant will discuss how it fits into your wider care, including longer-term management where spasms are severe or under-respond.
Most patients are managed comfortably with botulinum toxin alone for many years. Surgery (orbicularis myectomy) is reserved for the small minority whose spasms no longer respond adequately to injections, and is discussed only after a full assessment. Your consultant will also look for and treat aggravating factors such as dry eye or blepharitis, which can worsen spasm.
What happens during the treatment
Treatment is carried out in clinic and takes around 10 to 15 minutes. No anaesthetic is needed — the needle is extremely fine and most patients describe only a brief sting at each point. You can drive yourself home and return to normal activities the same day.
- Your consultant reviews your symptoms and examines the pattern and severity of spasm to plan the injection sites.
- The skin around the eyes is cleaned and the injection points are marked.
- Small, precise doses of botulinum toxin are injected into the orbicularis oculi muscle around the upper and lower eyelid and brow.
- For hemifacial spasm, additional points on the affected side of the face are treated as needed.
- You rest briefly, receive aftercare advice, and a follow-up or next session is planned for roughly 3–4 months later.
After your treatment
There is no downtime. Relief builds gradually over the first week as the toxin takes effect, peaks within about two weeks, then slowly wears off — which is why treatment is repeated. Here is what to expect:
Day of treatment
Tiny injection marks may be visible. Mild redness or a small bruise is possible. Avoid rubbing the area and stay upright for a few hours.
Days 3–7
The spasms begin to ease as the toxin takes effect. Most patients notice clear improvement in eyelid control within this window.
Week 2
Maximum effect is reached. Eye opening feels comfortable and controllable. Any temporary side effects have usually settled.
Months 2–3
Effect is well established. Towards the end of this period the benefit gradually fades and symptoms may start to return.
Months 3–4
Time for your next session. Dose and injection map are fine-tuned to your response to keep symptoms consistently controlled.
Cost & insurance
Pricing is transparent and includes the consultant's time and the toxin itself. There are no hidden extras for the injections.
- Consultation: consultant oculoplastic assessment from £200–£250.
- Botox treatment: from £400 per session, rising to around £650 for bilateral or more extensive treatment, including the toxin.
- Repeat sessions: usually every 3–4 months to maintain relief.
- Insurance: blepharospasm and hemifacial spasm are recognised medical conditions; many insurers (Bupa, AXA, Aviva, Vitality, WPA) cover treatment with a referral — we can advise on authorisation.
