Onset
Dysport kicks in fastest — most people notice change at day 2–3. Botox and Xeomin show effects starting day 3–5. Full results for all three at day 10–14.
Duration
All three last 3–4 months on average. Some patients report Xeomin lasting slightly less; some report Dysport lasting slightly longer. Individual variation matters more than brand.
Spread
Dysport diffuses more than Botox, which is helpful for large flat areas like the forehead but can be a drawback in precise areas like lip flip or crow's feet near the brow.
Unit conversion
Dysport units aren't equivalent to Botox units. 1 unit of Botox ≈ 2.5–3 units of Dysport. Compare total cost per area, not per unit.
Cost
Botox: $12–$18/unit. Dysport: $4–$7/unit (but ~3× the units). Xeomin: $10–$15/unit. Total per-area cost is roughly comparable across the three.
FAQ
Which is best for forehead lines?+
Dysport's spread can give a smoother forehead in a single pass. Botox is more predictable in patients prone to brow drop.
Which is best for a lip flip?+
Botox or Xeomin — precise placement matters more than spread. Dysport is usually not preferred here.
Can I switch between brands?+
Yes. There's no medical reason to stick with one. Many patients alternate based on availability or pricing.
