Coretox is Medytox’s botulinum toxin type A, manufactured free of complexing proteins (the accessory proteins removed, though it still contains albumin, so it is not protein-free). It is a freeze-dried 100 U vial with human serum albumin 0.5 mg and sodium chloride 0.9 mg, reconstituted with preservative-free saline before injection, and registered with Korea’s MFDS. Potency units are product-specific. Professional use only.
What is Coretox?
Coretox is Medytox’s botulinum toxin type A positioned as free of complexing proteins — the accessory proteins are removed, leaving the core neurotoxin, stabilised with human serum albumin and sodium chloride. Note that “free of complexing proteins” is not the same as protein-free, since the formulation still contains albumin. It is a freeze-dried 100 U vial, reconstituted with preservative-free saline before injection. Potency units are specific to this product and are not interchangeable with other botulinum toxin products.
How does Coretox differ from complex-type toxins?
Where Botulax and Nabota are complex-type toxins that retain the accessory complexing proteins, Coretox is manufactured free of those complexing proteins. It is a freeze-dried product, unlike the ready-to-use liquid Innotox, which is also a Medytox toxin.

| Botulax | Hugel · complex-type · 100/200/300 U |
What do clinics use Coretox for?
Clinics select Coretox for facial expression-line work where a toxin free of complexing proteins is preferred. Dosing, dilution and injection technique are product-specific and decided by the treating clinician per the manufacturer’s labelling.
