Description

Metox 100UI — Low-Protein Botulinum Toxin Type A

Metox 100UI is a botulinum toxin type A product from Maypharm Co., Ltd. in South Korea, produced on the company’s dedicated botulinum toxin production line. It reaches 99.8% purity and carries a low protein content, which helps reduce the risk of antibody formation over repeated treatments.

Unlike freeze-dried toxins, Metox uses a vacuum-drying manufacturing process. Because of this, the vial can appear nearly empty, sometimes showing only a faint dried film rather than visible powder. This is normal and not a sign of a defective product. The full dose remains present and dissolves completely once reconstituted.

Mechanism of Action

Metox works by temporarily relaxing the muscles responsible for expression lines and other movement-related wrinkles. Once injected, it blocks the nerve signals that trigger muscle contraction. As a result, the treated muscle can no longer tighten as forcefully. This softens the overlying skin’s dynamic wrinkles and helps prevent new ones from forming with repeated treatment.

Preparation & Dilution

Reconstitute Metox with sterile, preservative-free saline before use.

Dosage & Technique

Specific dosing per treatment zone depends on muscle size, patient anatomy, and treatment goals. A qualified practitioner should determine the exact plan for each patient, since the areas Metox treats range from small facial muscles to larger muscle groups like the masseter.

Frequently Asked Questions

What is Metox 100UI?
Metox 100UI is a low-protein, 99.8%-pure botulinum toxin type A product from Maypharm, used for facial wrinkle correction, masseter contouring, and hyperhidrosis treatment.

Why does the vial look nearly empty?
Metox uses a vacuum-drying process rather than standard freeze-drying, which produces a much thinner residue. The full 100-unit dose is present and dissolves completely once reconstituted.

Should I choose the 100UI or 200UI vial?
Metox 100UI works well as a single-vial, single-patient pack, while Metox 200UI suits multi-patient sessions or larger treatment areas that need a higher unit count.

What conditions can Metox treat beyond wrinkles?
Practitioners also use it for hyperhidrosis and muscle spasms, in addition to standard cosmetic wrinkle correction and facial contouring.
