Innotox 50U: The Ready-to-Use Liquid Botox — Clinical Guide

KOREAN FILLERS EU / APRIL 2026

Innotox 50U by Medytox represents a genuine innovation in botulinum toxin administration. As the only widely available liquid (non-lyophilised) botulinum toxin type A, Innotox eliminates the reconstitution step entirely — reducing preparation time, minimising dilution error risk, and streamlining the clinical workflow for busy aesthetic practices.

What Makes Innotox Different

All other major botulinum toxin products on the market — including Botulax, Nabota, Liztox, Metox, and Botox — are supplied as lyophilised (freeze-dried) powders. Before use, they must be reconstituted with preservative-free saline, a process that takes 5–10 minutes and introduces variability if the technique or volume is inconsistent.

Innotox is fundamentally different. It is manufactured as a stable liquid preparation, available ready to inject at 4 units per 0.1 ml. There is no reconstitution, no diluent to prepare, and no variation in concentration between practitioners or sessions.

Comparison: Innotox 50U vs Lyophilised Toxins

For practitioners currently using Botulax 100U, Nabota 100U, or other lyophilised products, switching to Innotox for appropriate treatment scenarios offers significant workflow benefits. The fixed concentration eliminates one variable in clinical outcomes, and the ready-to-use format is particularly valued in high-volume settings.

The 50-unit vial size means Innotox is typically used for single-patient sessions focusing on 1–3 treatment areas, while 100-unit lyophilised vials offer more flexibility for multi-area or multi-patient use. Many practitioners keep both in their refrigerator, using Innotox for convenience when speed matters and lyophilised products for larger treatment sessions.

Frequently Asked Questions

Does Innotox 50U need to be reconstituted?

No. Innotox 50U is a unique liquid formulation of botulinum toxin type A that comes pre-diluted and ready to inject. It requires no reconstitution with saline, making it the fastest botulinum toxin to prepare and reducing the risk of dilution errors.

How many units does Innotox 50U contain?

Innotox 50U contains 50 units of botulinum toxin type A in a liquid (non-lyophilised) formulation. The concentration is 4 units per 0.1 ml (12.5 ml total volume). Each vial is ready to use directly after removing from refrigeration.

What is the difference between Innotox and Botulax?

The main difference is the formulation. Botulax (and most other toxins) are freeze-dried powders requiring reconstitution. Innotox is a liquid formulation requiring no reconstitution. Both contain botulinum toxin type A from Medytox, are KFDA-approved, and have comparable clinical efficacy. Innotox offers convenience and dosing consistency.

How is Innotox 50U stored?

Innotox 50U must be stored at 2–8°C (refrigerated) and used before the expiry date. Once opened, use within the session. Unlike lyophilised toxins, there is no reconstitution to manage. The ready-to-use nature makes it ideal for busy clinic environments.

What areas can be treated with Innotox 50U?

Innotox 50U is suitable for all standard botulinum toxin facial areas: glabellar lines, forehead, crow's feet, brow lifting, and more. With 50 units per vial and a standard dilution of 4 U/0.1 ml, one vial is typically sufficient for a full glabellar + forehead treatment.
