In my practice, I generally use Botox®and Dysport ® as my drug of choice for the treatment and prevention of wrinkles. There are other brands of neurotoxins available in Canada but I find that these two brands provide consistent and predictable results. With our years of experience we have come in with our own conclusions to which drug is better.
They’re very similar. However, there are slight differences in how long they last and how quickly they take effect.
Here’s a breakdown:
| Feature | Botox® | ® |
|---|---|---|
| Onset of results | 3–7 days | 2–5 days (often slightly faster) |
| Duration of effect | Typically 3–4 months | Typically 3–4 months, sometimes up to 5 months in some patients |
| Diffusion (spread in tissue) | More localized (precise for small areas) | Spreads a bit more (good for larger areas like forehead) |
| Protein size | Larger molecule | Smaller molecule (may diffuse more easily) |
Which lasts longer?
On average, they last about the same (3–4 months).
Some studies and clinical experience suggest Dysport
® last slightly longer for certain people or areas (like the forehead), but this isn’t universal.
Individual metabolism, dose, treatment area, and injector technique play a bigger role in longevity than the brand itself.
✅ Summary:
Neither consistently “lasts longer” across all patients, though Dysport can have a faster onset and may last a bit longer for some people. This is consistently found in my practice. In fact I tested it myself by treating my own “crows feet” and found the that Dysport lasted a few week longer.
