Botox vs. Dysport: Which Neurotoxin Is Right for You?
An honest, side-by-side comparison of Botox and Dysport: how they work, how they're priced, how fast they kick in, how long they last, and which is best for your situation.
Botox and Dysport are the two most popular neurotoxins in cosmetic medicine, and the choice between them is one of the most common questions in injectable consultations. The short answer: they do the same job in slightly different ways, both work well, and the right choice usually comes down to your specific goals, your provider’s experience, and which loyalty program you prefer.
The core difference
Both Botox and Dysport are botulinum toxin type A, neuromodulators that temporarily relax muscles to soften dynamic wrinkles. The differences are in the protein structure and formulation:
- Botox (onabotulinumtoxinA) is made by Allergan. It’s the most well-known and longest-marketed neurotoxin for cosmetic use.
- Dysport (abobotulinumtoxinA) is made by Galderma. The molecule is smaller, which gives it slightly different diffusion and onset characteristics.
Head-to-head comparison
| Botox | Dysport | |
|---|---|---|
| Onset of results | 3–4 days | 2–3 days |
| Full effect by | Day 10–14 | Day 7–14 |
| Duration | 3–4 months | 3–4 months |
| Unit dosing | Standard reference | ~2.5–3 Dysport units = 1 Botox unit (rule of thumb) |
| Per-unit price | ~$10–$20 | ~$4–$8 (but more units needed) |
| Total cost per area | Similar | Similar (sometimes slightly less) |
| Diffusion pattern | Slightly more localized | Slightly more spread |
| Loyalty program | Allē (Botox + Juvederm) | ASPIRE (Dysport + Restylane) |
When to choose Botox
Botox is the right call when:
- You want a treatment with the longest track record and broadest provider familiarity.
- You’re treating precise areas like around the eyes or lip lines, where slightly more localized action matters.
- You’re already enrolled in or want the Allē rewards program (which also covers Juvederm fillers).
- Your provider has more experience and confidence with Botox dosing for your goals.
When to choose Dysport
Dysport tends to be the right call when:
- You want faster onset: Dysport typically shows results a day or two sooner.
- You’re treating larger areas like the forehead, where its slight diffusion can help with smoother, more even results.
- You prefer the ASPIRE loyalty program (which also covers Restylane fillers).
- Your provider recommends it for your specific muscle pattern.
What actually matters most
Honestly? Provider skill matters far more than the brand. A great injector will produce better results with either product than a mediocre injector will with either one. Both Botox and Dysport are excellent products with decades of safety data. The differences are real but small for most patients.
If you’ve tried one and were happy, there’s no compelling reason to switch. If you’ve tried one and didn’t love the result, switching brands AND providers is reasonable to consider. Ask your provider which they prefer for your specific concerns and why. A good answer suggests they understand both products well.
What about Xeomin, Jeuveau, and Daxxify?
For completeness:
- Xeomin is a “naked” toxin (no added protein), which may reduce the small risk of antibody development over years of use. Similar onset and duration to Botox.
- Jeuveau (“Newtox”) is positioned as a value alternative to Botox at a typically lower price.
- Daxxify is the newest option, with results that can last up to 6 months for some patients. It costs more per treatment but means fewer appointments per year.
All five FDA-approved neurotoxins are safe and effective when used by skilled injectors. Match the product to your priorities (cost, frequency, onset, longevity), then focus on finding a great provider.

Common questions
Is Dysport cheaper than Botox?
Per unit, Dysport is usually less expensive than Botox, but Dysport units aren't equivalent to Botox units. It typically takes ~2.5–3 Dysport units to equal 1 Botox unit, an industry rule of thumb rather than a studied conversion; the product labels say the units are not interchangeable. The per-treatment cost ends up similar, sometimes slightly lower for Dysport depending on the clinic.
Does Dysport work faster than Botox?
Generally yes. Most people see initial Dysport results in 2–3 days, vs. 3–4 days for Botox. Full results land around day 7–14 for both.
Does one last longer than the other?
Most clinical studies show similar duration of effect: 3–4 months. Individual results vary; some people find one lasts a bit longer for them than the other. There's no clear winner here.
Can I switch between Botox and Dysport?
Yes. Many people switch based on what their provider recommends, what's on promotion, or which loyalty program they're enrolled in. Your provider should adjust dosing because the units aren't 1:1.
Which is better for forehead lines vs. crow's feet?
Both work well for the same areas. Some providers favor Dysport for larger areas (forehead) because it tends to spread slightly more, and Botox for precise areas (around the eyes) for more localized control. This is provider preference more than a hard rule.
Are there other options like Xeomin, Jeuveau, or Daxxify?
Yes. Xeomin is "naked" (no protein additives, may reduce antibody risk over time), Jeuveau is similar to Botox at lower price, and Daxxify lasts noticeably longer (up to 6 months) but costs more. Choosing comes down to onset speed, duration, price, and what your provider has experience with.
