Why this product is different
Wondertox is a Chong Kun Dang (CKD) Korean botulinum toxin type A brand. Chong Kun Dang is one of the largest pharmaceutical companies in Korea (founded 1941, revenue ₩1.49 trillion / ~USD 1.15 billion in 2022), with broad clinical and commercial reach across the Korean and international pharmaceutical markets. Wondertox is supplied as freeze-dried (lyophilized) botulinum toxin type A in colourless transparent vials, with results in clinical trials supporting noninferiority versus controlled comparators for moderate-to-severe glabellar line improvement at week 4 and week 16.
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.

Yes. Wondertox is KFDA-approved (MFDS, the renamed Korean Ministry of Food and Drug Safety) for the temporary improvement of moderate to severe glabellar wrinkles in adults aged 19–65, and for the treatment of benign essential blepharospasm in patients aged 19–65 and equinus foot deformity due to spasticity in pediatric cerebral palsy patients aged 2 and above.
Wondertox 100U contains 100 units of botulinum toxin type A per vial; the 200U pack contains 200 units. Reconstitution volumes differ accordingly — typically 2.5 ml of 0.9% sterile saline for 100U and 5 ml for 200U. The active ingredient, manufacturing process, and excipient profile are equivalent across both pack sizes. The 200U pack is positioned for higher-volume multi-zone treatments or clinics with frequent botulinum toxin throughput.
