Why this product is different
The 200U vial provides twice the unit count of the standard 100U pack in a single vial, supporting multi-zone single-patient treatments or multi-patient sessions when shared-vial protocols are appropriate. Hutox 200U is produced using the same freeze-drying (lyophilization) manufacturing process and Huons proprietary working strain as Hutox 100U. The only difference is unit count per vial. Hutox is part of the Huons Group botulinum toxin product family in Korea, manufactured by Huons BioPharma. Sister product Liztox is manufactured by Humedix (also Huons Group).
Mechanism of action
Botulinum toxin type A is a presynaptic neuromuscular blocker. Following injection into target muscle, the toxin’s heavy chain binds to specific receptors on motor nerve terminals; the light chain is internalised into the nerve cytoplasm, where it enzymatically cleaves SNAP-25 — a SNARE complex protein required for acetylcholine vesicle fusion at the neuromuscular junction. Without SNAP-25, acetylcholine release into the synaptic cleft is blocked, the motor nerve cannot signal the muscle fibre to contract, and the targeted muscle relaxes. New axon terminals eventually sprout and restore neuromuscular signalling, at which point clinical effect wanes.

Frequently asked questions
What is Hutox 200U?
Hutox 200U is the 200-unit single-vial format of Huons BioPharma’s botulinum toxin type A. Each single-use vial contains 200 units of lyophilized white powder, reconstituted with 0.9% sterile saline before injection. Manufactured in the Republic of Korea.
Who manufactures Hutox 200U?
Hutox 200U is manufactured by Huons BioPharma Co., Ltd., part of the Huons Group in the Republic of Korea.
How is Hutox 200U different from Hutox 100U?
Hutox 200U contains 200 units of botulinum toxin type A per vial; Hutox 100U contains 100 units. Both share the same active ingredient, Huons proprietary working strain, freeze-drying process, and excipient profile.
How is Hutox related to Liztox?
Both are part of the Huons Group portfolio. Hutox is manufactured by Huons BioPharma; Liztox is manufactured by Humedix Co., Ltd. (also part of the Huons Group). They are sister products under the same parent group but distinct product lines.
Is Hutox 200U freeze-dried or vacuum-dried?
Hutox 200U is freeze-dried (lyophilized). After freeze-drying, a visible white powder cake or thin layer remains in the vial. This is distinct from vacuum-dried botulinum toxins which can appear nearly empty in the vial.
What is Hutox 200U commonly used for?
Common aesthetic application zones include glabellar lines, forehead lines, lateral canthal lines, masseter contouring, brow lift refinement, mentalis muscle, and platysma bands. The 200U pack is particularly suited for multi-zone single-patient treatments or shared-vial multi-patient protocols.
How is Hutox 200U different from Botulax 200U?
Both are 200-unit Korean freeze-dried botulinum toxin type A products from different manufacturers. Hutox is manufactured by Huons BioPharma. Botulax is manufactured by Hugel Pharma using the CBFC26 strain.
How is Hutox 200U different from Meditoxin 200U?
Both are 200-unit Korean freeze-dried botulinum toxin type A products from different manufacturers. Hutox is manufactured by Huons BioPharma. Meditoxin is manufactured by Medytox using the Hall A-hyper strain.
How long does Hutox 200U last?
Onset and duration vary with individual anatomy, muscle mass, metabolism, treatment zone, and dosing strategy. Practitioners can refer to published clinical literature for general expectations.
What are the storage requirements?
Store unopened vials at 2–8 °C, protected from light. Do not freeze. After reconstitution with 0.9% sterile saline, use within 24 hours when stored refrigerated.
