Coretox for Blepharospasm: Stop Involuntary Blinking and Regain Eye Control






Coretox for Blepharospasm: Stop Involuntary Blinking and Regain Eye Control



Blepharospasm is an involuntary contraction of the orbicularis oculi muscle, manifesting as frequent blinking, forced eyelid closure, and difficulty opening eyes. In severe cases, it can affect driving, reading, and daily activities. This is not simply tired eyes — it is a neurological movement disorder. Seoul’s Rappoel Dermatology uses Coretox to precisely inject the orbicularis oculi, relaxing overactive muscles to effectively control spasm symptoms and restore normal blinking frequency and eye control.

Symptoms and Causes of Blepharospasm

  • Primary Symptoms: Involuntary frequent blinking, forced eyelid closure, difficulty opening eyes
  • Aggravating Factors: Fatigue, stress, bright light, wind, reading, driving may worsen symptoms
  • Relieving Factors: Sleep, yawning, talking, singing may temporarily reduce symptoms
  • Potential Causes: Exact cause unknown, possibly related to basal ganglia dysfunction and dopamine imbalance
  • Demographics: Most common in those over 50, more women than men
  • Progressive: Symptoms typically worsen gradually, from mild increased blinking to severe forced closure

Coretox Blepharospasm Treatment Protocol

  1. Pre-treatment Assessment: Doctor evaluates spasm severity, affected areas, and functional impairment
  2. Injection Point Design: Multiple points designed in palpebral and orbital portions of orbicularis oculi, typically 5-7 points per side
  3. Precise Injection: Approximately 10-25 units Coretox per side, distributed across multiple points
  4. Avoiding Complications: Injections avoid levator palpebrae superioris to prevent ptosis
  5. Total Time: About 15-20 minutes
  6. Onset: Results appear in 3-7 days, peak at 2 weeks
  7. Duration: Typically 3-4 months, requiring regular repeat treatments

Treatment Effects and Life Improvement

  • Blinking Frequency: Involuntary blinking significantly reduced, normal blink rhythm restored
  • Eye Opening: Severe patients see significant improvement in difficulty opening eyes, enabling normal reading and driving
  • Social Function: No more embarrassment from frequent blinking in social situations
  • Safety: Driving safety greatly improved, no longer affected by spasms obstructing vision
  • Quality of Life: Overall quality of life significantly improved, daily activity ability restored

Coretox blepharospasm treatment is the internationally recognized first-line therapy. Coretox is a purified botulinum toxin produced by Korean company Hugel, with low impurity protein content, suitable for repeated injections in the delicate eye area. The key is dose control and injection placement — insufficient dose yields poor results, excessive dose may cause ptosis or double vision. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, with doctors experienced in periocular injection who achieve optimal balance between efficacy and safety.

Frequently Asked Questions

How long do Coretox blepharospasm treatment results last?
Typically 3-4 months. We recommend repeat treatment every 3 months to maintain results. Some patients find that after several consecutive treatments, spasm symptoms show some degree of long-term relief, but most patients need ongoing regular injections. The doctor adjusts dose and injection points based on each treatment’s response.
What are the side effects of Coretox for blepharospasm?
The most common side effects are mild local bruising and transient dry eye sensation. Less common but notable side effects include ptosis (if injection is too deep affecting levator palpebrae), double vision (affecting extraocular muscles), and incomplete eyelid closure. These side effects are typically temporary, resolving within weeks. Experienced doctors significantly reduce these risks.
Can blepharospasm resolve on its own? Why is Coretox needed?
Blepharospasm typically does not resolve spontaneously, and symptoms often progressively worsen. Early treatment can prevent symptom deterioration and functional impairment. Coretox is the internationally recognized first-line treatment for blepharospasm, with proven efficacy and safety. Without treatment, severe blepharospasm can lead to functional blindness, severely affecting quality of life.
Is Coretox eyelid injection painful?
Eyelid skin is sensitive, so there is mild pinching sensation, but each injection takes only 1-2 seconds. Ice or numbing cream can reduce discomfort. With 5-7 injection points per side, the entire process takes about 15-20 minutes. Mild soreness may occur but usually resolves within hours.
What preparation is needed for blepharospasm treatment in Korea?
We recommend contacting Rappoel Clinic first via WeChat (rappoelkr) or Line to describe your symptoms. The doctor needs to assess whether it is indeed blepharospasm and its severity. If you have had similar treatment elsewhere, please bring treatment records (injection doses and results). Rappoel Clinic is 3 minutes from Gangnam Station Exit 10, open 10 AM to 7 PM daily.
