Coretox is Medytox's answer to a specific question: what can be taken out of a botulinum toxin vial without compromising it. It is formulated without human serum albumin and without animal-derived protein, which is unusual in a lyophilised product and is the whole reason clinics specify it.
Medytox is the same manufacturer behind Innotox and Meditoxin, and the three sit at different points of the same thinking. Meditoxin is the conventional workhorse, Innotox removes the reconstitution step by shipping as a finished liquid, and Coretox strips the formulation back. A clinic that has settled on Medytox as a manufacturer usually ends up choosing between them on formulation rather than on price.
It ships as a lyophilised powder in a 100-unit vial and is reconstituted with sterile saline before use.
Why practitioners choose Coretox
No albumin, no animal-derived protein
The defining characteristic. For practitioners whose patients ask what is in the vial — and for those building a treatment menu around animal-free products — this is the reason the order lands here.
Precise, contained placement
Medytox positions Coretox on limited spread from the injection point. That matters most around the eyes and anywhere a small amount of unintended diffusion changes the outcome.
Natural movement retained
Used at sensible doses it softens expression lines without flattening the face, which is what most patients mean when they say they do not want to look treated.
A single-vial commitment
At 100 units, Coretox is a manageable way to introduce an albumin-free option alongside a conventional toxin already in the fridge.
What it is used for
Glabellar and forehead lines, lateral canthal lines, perioral wrinkles, and lower-face and chin contouring make up most aesthetic use. Neck lines and masseter reduction are common too.
Therapeutic applications include blepharospasm and limb spasticity. Approved indications vary by market, and treatment should stay inside your own scope of practice and clinical judgement.
Composition
The active ingredient is Clostridium botulinum toxin type A at 100 units per vial. It blocks acetylcholine release at the neuromuscular junction, relaxing the injected muscle temporarily and reversibly. The formulation excludes human serum albumin and animal-derived protein.

Handling
Check the seal and the appearance of the cake before use. Reconstitute with sterile 0.9% sodium chloride, adding the diluent gently down the wall of the vial rather than shaking. Follow Medytox's prescribing information for diluent volumes and per-site dosing rather than adapting a protocol from another brand.
Use reconstituted solution promptly, refrigerated in the interim. Duration of effect is typically three to six months, varying with dose, treated area, muscle bulk and individual metabolism.
A prescription product for administration by trained, licensed practitioners only. Contraindicated in pregnancy and breastfeeding, in known hypersensitivity to any component, where infection is present at the injection site, and in neuromuscular disorders such as myasthenia gravis.
