Key differences
Onset speed
- Dysport: 1–3 days
- Botox: 3–7 days
Duration
Similar — 3–4 months for both. After 3–4 repeat sessions, duration extends due to muscle weakening.
Dosing
1 unit of Botox ≈ 2.5–3 units of Dysport. So Dysport looks cheaper per unit but requires more. Total visit cost is nearly identical.
Zone preferences
Dysport better for large muscles (forehead, frown lines). Botox more precise for small zones (chin, masseter).
When to choose Dysport
- Event in 7–10 days — need fast onset
- Large zones (forehead, frown lines)
- Previous Botox felt "frozen"
- Galderma ASPIRE loyalty program
When to choose Botox
- Small targeted zones (chin, ML fold)
- Masseter (jaw) — Botox is more predictable here
- Axillary hyperhidrosis — standard choice
- Allergan Alle loyalty program
