Description

Metox 200UI — Low-Protein Botulinum Toxin Type A

Metox 200UI is a botulinum toxin type A product from Maypharm Co., Ltd. in South Korea, produced on the company’s dedicated botulinum toxin production line. This vial delivers double the toxin content of the standard 100-unit option, suiting multi-patient sessions or larger treatment areas.

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.

Saline Added (200U vial)	Resulting Concentration
2.0mL	10 units per 0.1mL
4.0mL	5 units per 0.1mL
5.0mL	4 units per 0.1mL
8.0mL	2.5 units per 0.1mL

Store the reconstituted solution refrigerated at 2–8°C, protected from light, and use it within 24 hours.

Treatment Areas

• Glabellar lines and forehead lines
• Lateral canthal lines (crow’s feet)
• Masseter contouring
• Brow lift refinement
• Mentalis muscle and platysma bands (neck)
• Lip contouring
• Hyperhidrosis and muscle spasms (therapeutic use)
• Multi-area or multi-patient sessions, given the higher unit count

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. Because this vial holds more total volume, it also suits combining several treatment areas or patients within a single reconstitution.
