Dysport. Fast onset, soft spread.
Dysport (abobotulinumtoxinA) — how it differs from Botox, where its wider diffusion helps, unit conversion, and onset timing.
Dysport is abobotulinumtoxinA — a botulinum toxin type A in the same family as Botox, made by Galderma. It relaxes targeted muscle the same way; the differences are practical. Dysport tends to show effect in 2–3 days, spreads slightly more once injected, and doses on its own unit scale.
How Dysport differs from Botox.
Both products are botulinum toxin type A. Both block the same nerve-to-muscle signal, soften the same dynamic lines, and wear off the same way. A patient who responds well to one will almost always respond to the other. The differences sit in the formulation — the proteins around the molecule and the way the dose is measured — and they show up in three places: onset, spread, and unit count.
Onset. Dysport tends to read earlier. Many patients see movement softening at 2–3 days, against 5–7 for Botox, with both reaching full effect around two weeks. For a patient treating ahead of an event, those few days sometimes decide the choice on their own.
Spread. Once injected, Dysport diffuses across a slightly wider area. Over a broad muscle like the frontalis — the forehead — that wider footprint can produce an even result with fewer injection points. Around the eyes and in small precision areas, the same property argues for a tighter formulation instead, so the effect stays exactly where it was placed.
Units. Dysport units are not Botox units. Conversion in practice runs roughly 2.5–3 Dysport units per Botox unit, so a sixty-unit Dysport treatment is not a bigger treatment — it's a similar dose on a different scale. Comparing per-unit prices across the two brands without converting is the most common pricing confusion we untangle at consultation.
Botox and Dysport, compared.
Both are FDA-approved for cosmetic use. The table reflects typical patterns; individual response varies, which is why we re-assess at the two-week follow-up.
| Botox | Dysport | |
|---|---|---|
| Active ingredient | OnabotulinumtoxinA | AbobotulinumtoxinA |
| Typical onset | 5 – 7 days | 2 – 3 days |
| Diffusion | Tighter; stays close to the injection point | Slightly wider spread per injection |
| Unit scale | Reference standard | Roughly 2.5 – 3 : 1 against Botox |
| Typical duration | 3 – 4 months | 3 – 4 months |
| Often suits | Precision areas — crow's feet, brow, lip flip | Broad zones — full forehead, larger muscle groups |
When we reach for Dysport — and when we don't.
The forehead is the argument for Dysport. A broad, active frontalis treated with a product that spreads a little further can come out smoother, with less of the banded look that under-placed precision dosing sometimes leaves. Faster onset is the second argument, and for some patients the deciding one.
We don't default to it everywhere. Crow's feet, the brow, a lip flip — small muscles next to muscles you very much want left alone — favor Botox or Xeomin, whose tighter diffusion keeps the margin clean. And some long-term patients simply respond better to one formulation than the other; when duration on one brand starts drifting shorter, switching within the family is a reasonable, low-stakes experiment.
None of this is brand loyalty. We stock four neurotoxins because patients differ; the product is chosen at consultation, after we've looked at your anatomy and heard what you're treating for.

Questions we get.
Dysport or Botox — which should I choose?
For broad areas like the forehead, or when you want visible effect within days, Dysport has the edge. For precision work around the eyes, brows and mouth, Botox's tighter spread usually wins. Both last 3–4 months. We make the call together at consultation, based on the areas you're treating.
Is Dysport cheaper than Botox?
Per unit, yes — but Dysport units are smaller, and a treatment takes roughly 2.5–3 times as many of them. Per treatment, the two usually land in a similar range at Los Angeles market rates. We quote by total treatment, confirmed in writing at consultation, so the unit math never surprises you.
How fast does Dysport work?
Most patients see softening at 2–3 days, with full effect around two weeks. That's a few days ahead of Botox, which typically reads at 5–7 days. If you're treating ahead of an event, build in the full two weeks regardless of product.
Does Dysport last as long as Botox?
Typically yes — both run 3–4 months for most patients. Individual metabolism matters more than brand here. Patients who find one product fading early sometimes hold duration better on the other, which is one reason a practice that stocks both is useful.
