Botox vs. Dysport: A Montreal Physician's Honest Perspective
This is one of the questions I am asked most often in consultation: which is better, Botox or Dysport? The honest answer is that neither is universally better. They are different products with different characteristics, and the right choice depends on the area being treated, the patient's anatomy, their prior experience with neuromodulators, and what they are trying to achieve.
Both are botulinum toxin type A products approved by Health Canada for cosmetic use. Both work by temporarily reducing the activity of targeted facial muscles, softening the expression lines caused by movement. Both are safe when administered by a trained physician using appropriate technique. The differences are real but nuanced.
How They Are Different
- Diffusion: Dysport tends to spread slightly more from the injection point. This can be an advantage in larger treatment areas like the forehead, where broader coverage is desirable. In smaller, more precise areas, tighter diffusion may be preferred.
- Onset: Dysport tends to show initial results slightly earlier, often within two to three days, compared to Botox, which typically shows full effect at 10 to 14 days.
- Unit equivalence: Dysport units are not the same as Botox units. Comparing prices by unit count is meaningless. What matters is the clinical dose needed for your specific anatomy.
- Duration: Both products typically last three to four months, though individual variation is significant and can extend to six months in some patients.
The question patients should be asking is not which product, but who is making the decision and on what basis. The product matters less than the physician's assessment of which option is appropriate for your anatomy and goals.
What I Use at GhalMédica
At GhalMédica, I work with both Botox and Dysport. The product I recommend depends on the areas being treated, the patient's previous response to either product, and my clinical assessment of what will produce the most natural, controlled result for their specific anatomy.
I do not have a default product. I have a default commitment to the outcome, which is a natural-looking result that respects the patient's facial dynamics rather than eliminating them.
What Natural Results Actually Look Like
The concern most patients raise in consultation is about looking frozen or done. This fear reflects real experiences. Frozen results are almost always a function of technique and dose, not product selection.
Appropriate neuromodulator treatment softens hyperkinetic movement without eliminating natural expression. The forehead should still move. The crow's feet should still register a genuine smile. The goal is a face that looks rested and radiant, not one that looks treated.
How to Know If You Are a Good Candidate
The best candidates are adults with dynamic expression lines, lines that appear with movement and may or may not be visible at rest. Static lines visible at rest may benefit from a combination approach that includes skin quality treatments alongside neuromodulators. A physician consultation is the correct starting point, not a price comparison.
