The quick decision
Dysport tends to suit
- Broader areas like the full forehead
- Wanting results a little faster
- A softer, more diffuse relaxation
Botox tends to suit
- Precise, small areas like crow’s feet
- Areas close to the eye, where spread matters more
- Treatments needing tighter placement control
What is actually different
Both Dysport and Botox are botulinum toxin type A – the same active mechanism, blocking the nerve signal to a muscle. They are not the same product, though. Different manufacturing processes produce molecules of different sizes, and that difference is what shows up in how each one behaves once injected.
Dysport’s smaller molecule tends to spread further from the injection point. That is not a flaw – it is genuinely useful for a broad, even muscle like the forehead, and genuinely less useful for a small precise area close to the eye, where you want the effect to stay exactly where it was placed.
Units are not 1-to-1
This is the detail that confuses almost everyone comparing the two. A unit of Dysport is not the same as a unit of Botox – they are measured differently, so unit counts cannot be compared directly.
The commonly used conversion is roughly 1 unit of Botox to about 2.5 units of Dysport for a comparable effect, though the exact ratio is debated in the clinical literature and is not perfectly linear across every dose and area. It is a useful rule of thumb, not an exact formula.
What that means for cost
Because the products are priced differently per unit, a like-for-like comparison has to account for the conversion, not just compare the per-unit price.
| Product | Units needed | Approximate cost |
|---|---|---|
| Botox, at $13.50/unit | 20 units | $270 |
| Dysport, at $4.50/unit | ~50 units (using the 2.5x conversion) | $225 |
In this example Dysport comes out somewhat less expensive for a comparable result, though the gap depends on the area and the conversion ratio actually used for your muscles. See current pricing for both.
Onset and how long each lasts
Dysport is often reported to show its first effect slightly sooner – closer to 2 to 3 days versus 3 to 4 for Botox – though the difference is modest and not something most people would notice without comparing side by side. Full effect for both is reached by around two weeks.
Duration is broadly comparable between the two, both averaging around 3 to 4 months. Neither has consistently strong evidence of lasting meaningfully longer than the other – individual factors like muscle strength and metabolism matter more than which product was used.
Why this matters at KORA specifically
Katie is a national clinical trainer for Galderma, the company that makes Dysport and Sculptra – a role in which she teaches injection technique to other medical professionals. That is a genuine point of difference when deciding where to have either product injected, not just a marketing line: it means the person choosing your dose and placement is trained to the standard other injectors are taught to meet.
Myths worth dropping
- “Dysport and Botox units are basically the same, just do the math directly.”
- They measure different things. A straight 1-to-1 comparison of unit counts is not meaningful – the roughly 2.5x conversion has to be applied.
- “One is objectively better than the other.”
- Neither is universally better. Each suits certain areas and certain goals better than the other, which is why some injectors use both depending on what is being treated.
- “Dysport is the ‘cheap’ version of Botox.”
- It is a different product with different manufacturing, not a discount alternative. The lower per-unit price reflects the different unit measurement, not lower quality.
- “Switching between them will cause problems.”
- Many people switch between the two, or use both for different areas, without issue. This is a normal part of practice, not something to be cautious about on its own.
Questions people ask
Is Dysport the same as Botox?
Both are botulinum toxin type A with the same basic mechanism, but they are different products – different manufacturing produces molecules that behave somewhat differently once injected, particularly in how far they spread from the injection point.
How do Dysport and Botox units compare?
They are not directly comparable. A commonly used conversion is roughly 1 unit of Botox to 2.5 units of Dysport, though the exact ratio varies by area and is debated in the literature.
Which lasts longer, Dysport or Botox?
Duration is broadly similar for both, averaging 3 to 4 months. Neither has strong, consistent evidence of lasting meaningfully longer than the other.
Which works faster, Dysport or Botox?
Dysport is often reported to show initial effect slightly sooner – around 2 to 3 days versus 3 to 4 – though the difference is modest.
Is Dysport cheaper than Botox?
Per unit, yes, but units are not equivalent between the two products. Once the roughly 2.5x conversion is applied, Dysport is often somewhat less expensive for a comparable result, though this depends on the area treated.
Can I switch from Botox to Dysport, or use both?
Yes. Many people switch between the two or use different products for different areas without any issue.
