Botox vs Dysport vs Bocouture for clinics
All three are botulinum toxin type A. They differ in vial sizes, how units convert, whether they contain complexing proteins, and whether they need cold-chain storage.
Updated 9 October 2026
| Brand | Active ingredient | Manufacturer | Vial sizes | Complexing proteins | Unopened storage | Units vs Botox (approx.) |
|---|---|---|---|---|---|---|
| Botox | onabotulinumtoxinA | Allergan (AbbVie) | 50 U, 100 U, 200 U | Yes (900 kDa complex) | 2–8 °C | Reference (1 U) |
| Dysport | abobotulinumtoxinA | Ipsen | 300 U, 500 U | Yes | 2–8 °C | About 2–3 U per Botox unit |
| Bocouture | incobotulinumtoxinA | Merz | 50 U, 100 U | No | Up to 25 °C | About 1 U per Botox unit |
Unit ratios are approximate values commonly cited in clinical literature. Units are not interchangeable between brands, and dosing is the treating clinician's decision.
Which to stock
- Botox: the brand patients ask for by name; needs 2–8 °C shipping.
- Dysport: larger unit counts per vial; clinics often use it for larger areas; needs 2–8 °C shipping.
- Bocouture: no complexing proteins, and unopened vials can be stored up to 25 °C, which lowers shipping cost.
