Coretox for Facial Asymmetry: Precision Toxin Correction for Uneven Faces and Crooked Smiles






Coretox for Facial Asymmetry: Precision Toxin Correction for Uneven Faces and Crooked Smiles



Facial asymmetry is a very common concern — nearly everyone has some degree of left-right difference. Significant asymmetry affects photo results, smile aesthetics, and overall facial harmony. Seoul’s Rappoel Dermatology uses Coretox to precisely relax overactive muscles on one side, adjusting the balance of muscle force between sides, effectively improving muscle-caused facial asymmetry.

Common Manifestations of Facial Asymmetry

  • Masseter Asymmetry: Unilateral chewing habits cause one-sided masseter hypertrophy, creating unequal lower face width
  • Crooked Smile: Stronger smile or mouth corner muscles on one side create uneven lip height when smiling
  • Eyebrow Asymmetry: Overactive frontalis on one side causes unequal brow height
  • Jaw Deviation: Mandibular position shift, with chin not on the facial midline
  • Uneven Eyes: Different orbicularis oculi tension creates size or shape differences between eyes

How Coretox Corrects Asymmetry

  1. Muscle Force Balancing: Coretox injected on the overactive side reduces its pulling force, bringing both sides toward balance
  2. Volume Adjustment: Relaxing hypertrophic muscles (e.g., masseter) causes gradual atrophy, reducing volume differences
  3. Dynamic Correction: Adjusting expression muscle contraction force improves dynamic asymmetry in smiling, blinking, etc.
  4. Non-Surgical: No incisions needed, suitable for mild to moderate asymmetry

Rappoel Asymmetry Correction Protocol

  1. Comprehensive Assessment: The physician takes comparative frontal and lateral photos, analyzing specific areas and causes of asymmetry
  2. Muscle Testing: The patient performs smile, clench, and brow-raise actions to observe bilateral muscle activity differences
  3. Injection Protocol: Targeted injection on the more active side:
  4. Masseter asymmetry: 25-35 units Coretox on the larger side
  5. Smile asymmetry: 5-10 units DAO on the stronger side
  6. Eyebrow asymmetry: 8-15 units frontalis on the higher side
  7. Contralateral Fine-Tuning: Micro-injection on the opposite side if needed
  8. Total Time: Approximately 15 minutes
  9. Onset: 3-7 days, peak at 2-4 weeks
  10. Duration: 4-6 months

Suitable and Unsuitable Cases

Suitable: Muscle-based asymmetry (unequal masseter, crooked smile, eyebrow height difference), mild to moderate asymmetry, those preferring non-surgical improvement.

Unsuitable: Skeletal asymmetry (jaw deviation requiring orthognathic surgery), congenital facial palsy, severe post-traumatic deformity.

Coretox correction of facial asymmetry requires the physician to accurately determine the cause — whether it is muscle, bone, or fat. For muscle-based asymmetry, Coretox is highly effective and safe. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, where physicians create personalized injection protocols through detailed facial analysis.

Frequently Asked Questions

Can Coretox completely correct facial asymmetry?
For muscle-based asymmetry, Coretox can significantly improve but may not achieve 100% symmetry. The human body naturally has some asymmetry, and pursuing absolute symmetry is unrealistic and unnatural. Coretox aims to reduce noticeable asymmetry to an imperceptible level. For skeletal asymmetry, Coretox has limited effect and orthognathic surgery may be needed.
How much Coretox is needed for asymmetry correction?
Dosage varies by asymmetry type and degree. Masseter asymmetry: 25-35 units on the larger side; smile asymmetry: 5-10 units; eyebrow asymmetry: 8-15 units. Multi-area combined treatment may total 50-70 units. The physician precisely calculates dosage based on muscle mass and asymmetry degree.
Will injecting only one side cause imbalance?
No. Coretox reduces the overactive side’s muscle force to balance with the other side, not creating new imbalance. The physician precisely assesses bilateral differences before injection and calculates the needed adjustment dose. Micro-injection on the opposite side may be used for fine-tuning if necessary.
How long do results last? Is repeat treatment needed?
Typically 4-6 months. A follow-up at 4 months after the first treatment is recommended, then maintenance every 5-6 months. Regular maintenance helps bilateral muscle force stabilize toward balance, with improving long-term results. If treatment stops, asymmetry gradually returns to pre-treatment levels.
How much does asymmetry correction cost in Korea?
Costs depend on injection areas and dosage. Single-area correction (e.g., masseter or eyebrow) costs less; multi-area combined correction costs more but provides more comprehensive results. Rappoel uses Korean Coretox with transparent pricing. Consult via WeChat (rappoelkr). The clinic is 3 minutes from Gangnam Station Exit 10.
