BOTOX 50 Units — Allergan's onabotulinumtoxinA
BOTOX 50 Units is Allergan’s onabotulinumtoxinA, the original botulinum toxin type A product and the one with the largest published clinical record in the category. This listing is genuine Allergan-manufactured stock in Korean-market packaging, which means the carton and insert carry Korean labelling.
The 50-unit vial is the smallest BOTOX presentation. It suits single-area treatment — a glabellar complex at 20 units leaves far less waste than opening a 100-unit vial would, and reconstituted product cannot be carried to the next patient.
Two practical notes. The excipients scale with vial strength, so a 50-unit vial contains half the albumin and sodium chloride of a 100-unit vial, and the dilution volumes are correspondingly halved. And because this is Korean-market stock, confirm what your own jurisdiction requires for imported prescription medicines before ordering.
OnabotulinumtoxinA has the longest marketing history and the largest body of published clinical data in this category.
50 units suits single-area treatment with minimal waste, since reconstituted product is single-patient use.
0.25 mg albumin and 0.45 mg sodium chloride — exactly half the 100-unit vial, and 1.25 mL reaches 4 U per 0.1 mL.
Carton and insert carry Korean labelling. Confirm your own import requirements before ordering.
Why practitioners choose BOTOX 50 Units
Decades of published safety and efficacy data across both aesthetic and therapeutic use, which is why it remains the reference point other products are compared against.
Dosing conventions for onabotulinumtoxinA are established across far more clinical literature than for any other product in the class.
A 50-unit vial matches a glabella, a forehead or a crow’s feet treatment without leaving most of a 100-unit vial to discard.
Not a generic or a comparable product — this is the originator, in Korean-market packaging, with batch and expiry verifiable before dispatch.
Aesthetic & therapeutic applications
Areas commonly treated with onabotulinumtoxinA. This product holds a wider range of approvals than most in the category, but which of them apply is determined entirely by your national registration — always work from the prescribing information approved where you practise.
Vertical lines between the brows produced by corrugator and procerus activity. The most widely approved aesthetic indication for onabotulinumtoxinA, and the one with the deepest clinical literature behind it. A 20-unit glabellar complex fits a 50-unit vial with room to spare.
Lines at the outer eye produced by orbicularis oculi activity. An approved aesthetic indication for onabotulinumtoxinA in a number of markets — check your own registration.
Lines produced by frontalis activity, approved in several markets for onabotulinumtoxinA. Treated conservatively and generally alongside the glabella, since the frontalis holds the brow up.
OnabotulinumtoxinA carries therapeutic approvals across a range of conditions in various countries. Which apply where you practise, and what training they require, is a matter for your national authority rather than a supplier listing.
Botulinum toxin products are prescription-only medicines. Any use outside the indications approved in your jurisdiction is a clinical decision made by the treating practitioner under their own professional judgement and local regulatory framework. Korea Filler Experts supplies the product; nothing here should be read as a recommendation to treat any medical condition.

Reading the carton
Before you accept a delivery, check five things:
- The unit count says 50 U. Excipients and dilution volumes both differ between vial strengths.
- The tamper-evident seal and holographic film are intact — Allergan product carries authentication features and these are worth inspecting on receipt.
- The lot / batch number on the carton matches the number printed on the vial.
- The expiry date leaves you enough working life — we do not dispatch stock with under 6 months remaining unless agreed in advance.
- The carton arrived cold, with the coolant pack still chilled.
Korean labelling: the insert supplied with this stock is the Korean-market document. Work from the prescribing information approved in your own jurisdiction for dosing.
What each component does
- OnabotulinumtoxinA — the active substance, a purified botulinum toxin type A neurotoxin complex. It temporarily reduces the release of acetylcholine at the neuromuscular junction, lowering activity in the injected muscle.
- Albumin (human), 0.25 mg — stabilises the toxin protein through vacuum drying, storage and reconstitution. A plasma-derived protein; if a patient raises that specifically, an albumin-free product such as Coretox or Innotox is the alternative.
- Sodium chloride, 0.45 mg — brings the reconstituted solution to a tonicity suitable for injection.
- No preservative — which is why the diluent must also be preservative-free and why a reconstituted vial is single-patient use.
Why the figures differ from the 100-unit vial
BOTOX excipients scale directly with vial strength. A 50-unit vial contains 0.25 mg albumin and 0.45 mg sodium chloride; a 100-unit vial contains 0.5 mg and 0.9 mg; a 200-unit vial, 1.0 mg and 1.8 mg.
This matters because the 100-unit figures circulate widely online and are often quoted against 50-unit stock by mistake — an error we had to correct in this listing itself. If you are checking a carton against a reference, make sure the reference is for the same vial strength. The same principle applies to the diluent volume: 1.25 mL gives 4 units per 0.1 mL in a 50-unit vial, where a 100-unit vial would need 2.5 mL.
How to prepare and use BOTOX 50 Units
Reference information for licensed practitioners. The volumes below are those published for a 50-unit vial and are half the corresponding figures for a 100-unit vial. Reconstitution and administration must follow the prescribing information approved in your market.
Step by step
-
Confirm the vial strength
Check the carton says 50 U before calculating anything. Published dilution tables for BOTOX most often show 100-unit volumes, which would double your intended concentration.
-
Inspect the packaging
Check the tamper-evident seal and holographic film, then the lot number and expiry date on both carton and vial.
-
Draw the diluent
Use preservative-free 0.9% sodium chloride injection only. For 4 units per 0.1 mL, draw 1.25 mL.
-
Introduce the diluent slowly
Insert the needle at an angle and let the vacuum draw the saline in. Direct the stream against the vial wall rather than onto the powder. If the vacuum does not draw the saline in, discard the vial.
-
Mix gently
Rotate the vial slowly to dissolve the contents. Do not shake vigorously. The solution should be clear, colourless and free of particulates.
-
Record and use promptly
Note the reconstitution date and time on the vial, store at 2–8 °C, and administer within the period stated in your approved prescribing information — for BOTOX this is within 24 hours of reconstitution.
Dilution reference
| Diluent added | Units per 0.1 mL | Total volume |
|---|---|---|
| 0.63 mL | 8.0 U | 0.63 mL |
| 1.0 mL | 5.0 U | 1.0 mL |
| 1.25 mL | 4.0 U | 1.25 mL |
| 2.0 mL | 2.5 U | 2.0 mL |
| 2.5 mL | 2.0 U | 2.5 mL |
Administration notes
These volumes are for a 50-unit vial. Adding 2.5 mL to a 50-unit vial gives 2 units per 0.1 mL, not 4. Most BOTOX dilution tables you will find online are written for the 100-unit vial, so check the strength the table refers to before using it.
Materials needed: preservative-free 0.9% sodium chloride injection, a sterile syringe with a fine-gauge needle, gloves and alcohol swabs. None of these are supplied with the vial. BOTOX contains no preservative, so the diluent must not contain one either.
- Units of botulinum toxin are product-specific. Do not convert or substitute units between onabotulinumtoxinA and any other product — the published literature on onabotulinumtoxinA dosing does not transfer to other brands, and the reverse is equally true.
- Dose per site, total dose and injection technique must follow the prescribing information approved in your market.
- Administer within 24 hours of reconstitution, keeping the vial at 2–8 °C in the interim.
- Single-patient use. Discard any remainder rather than carrying it to the next appointment.
- Treatment intervals should not be shortened below the minimum stated in the prescribing information.
After treatment
- Avoid rubbing or massaging the treated area for at least 24 hours
- Stay upright and avoid lying down for 4 to 6 hours
- Avoid strenuous exercise for 24 to 48 hours
- Avoid saunas, hot tubs and excessive sun exposure for at least 24 hours
- Mild redness, swelling or bruising can occur and usually settles within a few days
Storing and handling BOTOX 50 Units
Store refrigerated at 2–8 °C in the original carton, protected from light. Do not freeze. Work to the expiry date printed on the carton.
If you stock more than one vial strength, keep them physically separated. The excipients and the dilution volumes both differ.
Keep at 2–8 °C and administer within 24 hours of reconstitution, as stated in the prescribing information. Single-patient use only — there is no preservative in the formulation.
Transfer stock into a monitored medical refrigerator on arrival and keep a temperature log. If a shipment arrives warm, photograph the packaging and contact us before putting it into clinical service.
Do not use the vial if the vacuum fails to draw the diluent in, if the reconstituted solution is cloudy or contains particles, if the expiry date has passed, if the tamper-evident seal is broken, or if the cold chain is known to have been broken. Dispose of unused product and used vials as clinical waste in line with local requirements.
What's included with BOTOX 50 Units
Diluent (preservative-free 0.9% sodium chloride injection), syringes and needles are not supplied with this product and must be sourced separately. BOTOX contains no preservative, so the diluent must be preservative-free.
BOTOX 50 Units — frequently asked questions
What is BOTOX 50 Units?
BOTOX 50 Units is Allergan’s onabotulinumtoxinA, supplied as a vacuum-dried powder in a single 50-unit vial and reconstituted with preservative-free 0.9% sodium chloride before injection by a licensed practitioner. This listing is Korean-market packaging.
How much albumin and sodium chloride does a 50-unit vial contain?
0.25 mg of albumin (human) and 0.45 mg of sodium chloride — exactly half the quantities in a 100-unit vial, because BOTOX excipients scale with vial strength.
The 100-unit figures (0.5 mg and 0.9 mg) circulate widely and are frequently misquoted against 50-unit stock. We had corrected that error in this listing itself.
How much saline do I add to a 50-unit vial?
1.25 mL of preservative-free 0.9% sodium chloride gives 4 units per 0.1 mL, the most commonly used reference concentration.
Be careful with dilution tables found online — most are written for the 100-unit vial, where 2.5 mL gives the same concentration. Using the 100-unit volume on a 50-unit vial halves your concentration.
Why choose the 50-unit vial over the 100-unit?
Waste. Reconstituted BOTOX is single-patient use and must be administered within 24 hours, so a vial opened for a 20-unit glabellar treatment is largely discarded.
If your list is single-area treatments rather than full-face sessions, the smaller vial is the more economical choice despite the higher price per unit.
What does "Korean-market packaging" mean for me?
The carton and package insert carry Korean labelling, because this stock was manufactured and labelled for the Korean market. The product itself is genuine Allergan manufacture.
It does mean you should confirm what your own jurisdiction requires for prescription medicines sourced this way, and that you should work from the prescribing information approved where you practise rather than from the Korean insert.
What is onabotulinumtoxinA approved to treat?
Approvals vary considerably by country. Across markets, onabotulinumtoxinA holds aesthetic approvals for glabellar lines and, in many countries, lateral canthal lines and forehead lines; it also holds a range of therapeutic approvals in various jurisdictions.
Which of those apply where you practise is a question for your national drug authority. We supply the product and cannot tell you what you are licensed to treat with it.
Can I substitute BOTOX units for another brand's units?
No. Units of botulinum toxin are specific to each product and are not interchangeable. This matters particularly with onabotulinumtoxinA, because so much of the published dosing literature was generated with it and is sometimes applied to other brands by mistake. Dosing must come from the prescribing information for the product in your hand.
How long after reconstitution can I use it?
The prescribing information specifies administration within 24 hours of reconstitution, with the vial kept at 2–8 °C in the interim. There is no preservative in the formulation, which is the reason for the limit.
What happens if my shipment arrives warm?
Do not use it. Photograph the outer box, the insulated liner, the coolant packs and the vial carton, and contact us the same day with your order number. We will review the cold-chain evidence and arrange a replacement where the failure occurred in transit.
Who is allowed to buy this product?
Botulinum toxin is a prescription-only medicine. Purchase and use are restricted to licensed healthcare professionals qualified to prescribe or administer injectable prescription medicines in their jurisdiction, with appropriate training in the relevant anatomy and injection technique. We do not sell to consumers.
