Allergan (an AbbVie company) · Republic of Ireland (Westport facility); imported via Korean wholesale channel
Allergan Botox 50U is FDA-approved onabotulinumtoxinA manufactured by Allergan (an AbbVie company) at the Westport, Ireland facility. Each single-use vial contains 50 units of botulinum toxin type A (Hall A strain, ATCC 3502), supplied as vacuum-dried powder for reconstitution. The 50-unit pack is positioned for smaller-area aesthetic treatments or precise dosing protocols.
This product is vacuum-dried. The vial may appear nearly empty before reconstitution — this is normal product appearance, not a defect. The full dose is present and dissolves into a clear, colourless solution when reconstituted with sterile saline.
Allergan Botox is manufactured by Allergan (an AbbVie company) at the Westport, Ireland facility. This listing is the Korean-imported wholesale channel version with English labels and KFDA registration — transparent disclosure for buyers who specifically want Korean-channel inventory pricing. The active ingredient onabotulinumtoxinA, manufacturing facility, and product specifications are identical to Allergan Botox sold through other regional channels.
Why this product is different
Allergan Botox carries FDA approval for cosmetic glabellar lines (2002), lateral canthal lines (2013), and forehead lines (2017), plus a wide range of therapeutic indications including chronic migraine, cervical dystonia, blepharospasm, hyperhidrosis, and overactive bladder. It is the original and most-studied botulinum toxin type A product, with decades of post-marketing safety data accumulated across global markets. Allergan is owned by AbbVie since the 2020 acquisition. The 50-unit pack is the smaller of Allergan Botox’s standard formats (others include 100U and 200U) and is suited for smaller treatment areas or precise dosing in early-phase patients.
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
Allergan Botox 50U is the smaller single-use pack of FDA-approved onabotulinumtoxinA (Hall A strain). Each vial contains 50 units of botulinum toxin type A as vacuum-dried powder for reconstitution with 0.9% sterile saline before injection. The 50-unit pack is positioned for smaller-area aesthetic treatments or precise dosing protocols.
Allergan Botox is manufactured by Allergan (an AbbVie company) at the Westport, Ireland facility. AbbVie acquired Allergan in 2020. The Westport facility has been the global production site for onabotulinumtoxinA since the product was first approved by the FDA in 1989 for therapeutic use, and 2002 for cosmetic glabellar lines.
Yes. This listing is the Korean-imported wholesale channel version with English labels and KFDA registration. The active ingredient, manufacturing facility, and product specifications are identical to Allergan Botox sold through other regional channels. This is the legitimate Allergan-manufactured product, not a generic or counterfeit.
Allergan Botox is vacuum-dried. Vacuum-drying produces a much thinner product layer than freeze-drying — the vial may appear nearly empty or have only a faint dried film. This is normal product appearance, not a defect. The full 50 units of onabotulinumtoxinA are present and dissolve into a clear, colourless solution when reconstituted with sterile saline.
FDA-approved cosmetic indications include glabellar lines (frown lines, since 2002), lateral canthal lines / crow’s feet (2013), and forehead lines (2017). Therapeutic indications include chronic migraine, cervical dystonia, blepharospasm, strabismus, upper limb spasticity, severe primary axillary hyperhidrosis, and overactive bladder. Specific dosing per indication is determined by the treating practitioner.
Allergan Botox 50U contains 50 units of onabotulinumtoxinA per vial; the standard 100U pack contains 100 units; the 200U pack contains 200 units. The 50-unit pack is suited for smaller treatment areas, precise micro-dosing, or single-patient sessions where 100U would be wasteful. Active ingredient, manufacturing process, and excipient profile are equivalent across all three pack sizes.
Both are FDA-approved botulinum toxin type A products. Allergan Botox contains onabotulinumtoxinA (manufactured by Allergan in Westport, Ireland). Dysport contains abobotulinumtoxinA (manufactured by Ipsen in France). The two products use different manufacturing processes, different complex protein profiles, and — critically — their units are calibrated independently and are NOT interchangeable on a 1:1 basis.
Both are FDA-approved botulinum toxin type A products. Allergan Botox contains onabotulinumtoxinA stabilized with human serum albumin and includes complexing accessory proteins (900 kDa complex). Xeomin contains incobotulinumtoxinA — only the 150 kDa pure neurotoxin core without complexing proteins (Merz characterizes this as their XTRACT proprietary purification). Both products are 1:1 unit-interchangeable per published clinical literature.
Onset and duration vary with individual anatomy, muscle mass, metabolism, treatment zone, and dosing strategy. Practitioners can refer to FDA prescribing information and published clinical literature for general expectations specific to the indication.
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. Discard unused reconstituted product per institutional protocol.

I was a bit nervous about buying more online, but checking around convinced me they were legit. Their tracker is fantastic – seeing the order being packed and shipped instantly made me relax. Delivery was fast and kept cold. Using it on clients, it’s the same reliable Allergan quality I trust – the frown lines soften beautifully and last months.

Needed 10 vials for our clinic and fillersfairy had the best price after comparing a few sites. The 5% discount on 10 units definitely adds up! Ordering was straightforward, and I really liked being able to see exactly where my order was in the process after checkout – felt much more reassuring than other places where you just hope it shows up. Everything arrived perfectly chilled and on time.
