Maypharm's vacuum-dried botulinum toxin type A
Metox is a botulinum toxin type A product from Maypharm Co, Ltd. in South Korea, supplied as a vacuum-dried powder in a single 100-unit vial and reconstituted with preservative-free 0.9% sodium chloride before use.
The specification worth understanding is the vacuum-dried format. Where most toxins in this category are freeze-dried, vacuum drying removes moisture under reduced pressure without the freezing step. In practice the handling is the same — the vial looks almost empty, you reconstitute with saline, you store at 2–8 °C — but it is a real process difference rather than a marketing term, and worth knowing if a colleague asks why the cake looks slightly different.
Beyond that it is a conventional formulation: botulinum toxin type A stabilised with human serum albumin, with sodium chloride for tonicity. Maypharm is a Korean manufacturer active across aesthetic injectables.
Moisture removed under reduced pressure rather than by freeze-drying. Handling is unchanged; the process differs.
Botulinum toxin type A with human serum albumin and sodium chloride — familiar excipients.
Supplied as a powder, so concentration is chosen at the bench to suit the treatment area.
100 U and 200 U share the same formulation, so vial size can be matched to session volume.
Why practitioners choose Metox 100UI
Despite the vacuum-dried format, it reconstitutes, stores and injects exactly as a freeze-dried toxin does — no change to an established workflow.
Human serum albumin as stabiliser and sodium chloride for tonicity, which is the pairing most practitioners in this category already work with.
Supplied as a powder rather than a solution, so concentration is set at the bench to suit the treatment area.
Maypharm Co, Ltd. is active across aesthetic injectables, so supply tends to be consistent.
Aesthetic & therapeutic applications
Areas commonly treated with this product. Approval status differs between markets — always work from the prescribing information registered in the country where you practise.
The corrugator and procerus complex that produces the vertical lines patients call their “elevens”. Conventional dosing spreads the total across several points spanning both corrugators and the procerus, with the pattern set by how strongly the muscles pull on animation rather than by how deep the lines look at rest.
Lines at the outer eye produced by orbicularis oculi activity. Widely treated in aesthetic practice; whether it is an approved indication for this product depends on your market.
Horizontal lines from frontalis activity, typically treated with small doses across several points rather than concentrated. A practitioner decision within local regulations.
Masseter and platysma treatment for muscle contouring. Approval status varies widely by country and this is frequently a practitioner-led application rather than a labelled indication.
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 four things:
- 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 seal is intact and the vial has not been disturbed.
- The carton arrived cold, with the coolant pack still chilled.
Vial looks empty? Vacuum drying leaves the contents as a thin film rather than a visible cake, so this is expected and is not a sign of a short fill. The powder becomes obvious once saline is introduced.
What each component does
- Botulinum toxin type A — the active substance. It temporarily reduces the release of acetylcholine at the neuromuscular junction, lowering activity in the injected muscle.
- Human serum albumin — stabilises the toxin protein through drying, storage and reconstitution. This is a human blood derivative; if a patient raises that specifically, an albumin-free product such as Coretox or Innotox is the alternative.
- Sodium chloride — brings the reconstituted solution to a tonicity suitable for injection.
How to prepare and use Metox 100UI
Reference information for licensed practitioners. Reconstitution and administration must follow the prescribing information approved in your market and your own clinical governance procedures.
Step by step
-
Inspect the vial
Check the label, lot number and expiry date, and confirm the seal is intact. A vacuum-dried vial often looks empty — that is expected.
-
Prepare the diluent
Draw the required volume of preservative-free 0.9% sodium chloride injection into a sterile syringe.
-
Disinfect the stopper
Wipe the exposed rubber stopper with an alcohol swab and allow it to dry.
-
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.
-
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 use within the period stated in your approved prescribing information.

Storing and handling Metox 100UI

Metox 100UI — frequently asked questions
What is Metox 100UI?
Metox 100UI is a botulinum toxin type A product manufactured by Maypharm Co, Ltd. in South Korea. It is supplied as a vacuum-dried powder in a single 100-unit vial and reconstituted with preservative-free 0.9% sodium chloride before injection by a licensed practitioner.
What does "vacuum-dried" mean, and does it change anything?
Most toxins in this category are freeze-dried — frozen, then dried under vacuum. Vacuum drying removes moisture under reduced pressure without the freezing step.
For your workflow it changes nothing: same reconstitution, same 2–8 °C storage, same handling. It is a genuine process difference rather than a marketing term, and the main practical consequence is that the dried contents can look even less visible in the vial.
Why does the vial look empty?
Vacuum drying leaves the contents as a very thin film rather than a visible cake. This is expected and is not a sign of a short fill or a counterfeit. The powder becomes obvious once saline is introduced.
How should I dilute a 100 U vial?
Dilution volume is chosen by the practitioner. Adding 2.5 mL of preservative-free 0.9% sodium chloride gives 4 units per 0.1 mL, which is a commonly used concentration; the reference table above lists other volumes.
Does it contain human serum albumin?
Yes, 0.5 mg per vial, used as the stabiliser. Albumin is a human blood derivative. If a patient raises that specifically, Coretox and Innotox are albumin-free alternatives we also supply.
Should I order the 100 U or 200 U vial?
Both share the same formulation, so the choice is about session volume. The 100 U vial suits face-focused lists; the 200 U vial reduces how many you open when treating larger muscle groups. Reconstituted product is single-patient use, so size the vial to the session.
Can I substitute Metox units for another brand's units?
No. Units of botulinum toxin are specific to each product and are not interchangeable between brands. Dosing must be taken from the prescribing information for the product in your hand.
What shelf life will my stock have?
We do not dispatch stock with less than six months of remaining shelf life unless you have specifically agreed to it. If you need a particular expiry window, tell us before you order and we will allocate accordingly.
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.
