Botox vs Dysport: A Physician's Comparison Guide
If you're considering wrinkle-softening injections in Richmond or Vancouver, you've likely come across two names: Botox® (onabotulinumtoxinA by Allergan) and Dysport® (abobotulinumtoxinA by Galderma). Both are Health Canada-approved botulinum toxin type A products, but they are not identical. Understanding the differences can help you and your physician choose the best option for your goals.
How They Work: The Same Core Mechanism
Both products temporarily block acetylcholine release at the neuromuscular junction, relaxing overactive muscles. The result: softened expression lines, slimmer jawlines, and reduced sweating — without surgery.
Key Differences
1. Molecular Size & Diffusion
- Botox has a larger molecular complex, staying more localized at the injection site.
- Dysport has a smaller complex, allowing it to spread more across a wider area.
What this means for you: Dysport may be preferred for broad areas like the forehead, while Botox excels in precise, small-area treatments like crow's feet or lip flips.
2. Onset Speed
- Dysport: Results may appear in 2-3 days
- Botox: Typically takes 3-5 days to show effect
If you have an event coming up soon, Dysport's faster onset may be advantageous.
3. Unit Conversion
Dysport and Botox are not 1:1 in units. Roughly 2.5-3 Dysport units equal 1 Botox unit. This doesn't mean Dysport is weaker — it's simply a different dosing scale.
4. Duration
Both typically last 3-4 months for expression lines. Some patients report Dysport wearing off slightly sooner; others find no difference. Masseter treatments with either product can last 4-6 months.
5. Price in Richmond BC
Per-unit pricing differs because of the conversion ratio. When calculated per treatment area, the total cost is often comparable. At RAAC Richmond, we price transparently and recommend based on your anatomy, not product margins.
Which Should You Choose?
| Factor | Botox | Dysport |
|---|---|---|
| Precision areas (lip flip, bunny lines) | ✅ Preferred | Good |
| Broad areas (forehead) | Good | ✅ Preferred |
| Faster onset | 3-5 days | ✅ 2-3 days |
| First-time patients | ✅ Most studied | Excellent track record |
| Masseter slimming | ✅ Excellent | ✅ Excellent |
The RAAC Approach
At our Richmond clinic, Dr. Charles Jiang doesn't prescribe a "one product fits all" approach. During your consultation, he evaluates:
- Your facial muscle anatomy and strength
- Dynamic vs. static line assessment
- Your aesthetic goals (subtle refinement vs. maximum smoothing)
- Previous neuromodulator history and response
We stock both authentic Botox (Allergan) and Dysport (Galderma) and choose based on what will give you the best outcome — not what's most profitable.
