Illume Aesthetics Blog
Nineteen thousand people google “Dysport vs Botox” every month. Most of them end up reading the same recycled article that says “they’re basically the same thing, talk to your provider.”
That’s not helpful. You’re here because you want to know the real differences — the ones that affect what you see in the mirror and what you feel in your face. So let’s actually answer the question.
We use both Dysport and Botox at Illume. Daily. On the same patients. Sometimes in the same appointment. We don’t favor one over the other. We favor whichever one is right for the area being treated on the face in front of us. That perspective — from a practice that uses both strategically rather than defaulting to one — is what makes this comparison worth reading.
They’re the Same Category. They’re Not the Same Product.
Both Dysport and Botox are botulinum toxin type A neuromodulators. Both are FDA-approved. Both relax the muscles that cause dynamic wrinkles. Both are injected. Both are temporary. Both have been used safely for over a decade in aesthetic medicine.
But they’re made by different companies (Dysport by Galderma, Botox by Allergan), with different formulations, different molecular structures, and different behavior once they’re under your skin. Those differences aren’t academic — they affect the result.
The Five Differences That Actually Matter
1. How fast it works
Dysport: Two to three days. Botox: Three to five days.
This isn’t a huge gap, but it’s consistent. If you’re getting treated on Tuesday for a Saturday event, Dysport gives you an extra day or two of visible result. For routine treatments where timing doesn’t matter, this difference is irrelevant. But when it matters, it matters.
2. How it spreads in the tissue
This is the most clinically significant difference — and the one most articles gloss over.
Dysport has a smaller protein complex than Botox. Once injected, it diffuses more broadly through the surrounding tissue. Think of it like dropping watercolor paint on wet paper — it feathers outward from the injection point.
Botox stays more localized. It affects the muscle closer to where it was placed without spreading as much to adjacent tissue. Think of it like dropping ink on dry paper — it stays roughly where it lands.
Why this matters in practice:
For your forehead — broad, flat muscle — Dysport’s natural spread is an advantage. It creates smooth, even relaxation across the entire surface without the “lines of demarcation” that can occur when a more localized product doesn’t blend between injection points. This is why many experienced injectors prefer Dysport for foreheads.
For your crow’s feet — small, delicate area right next to your eye muscles — Botox’s localized behavior is often preferred. You want the wrinkle-causing muscle relaxed without the product migrating to the muscle that lifts your eyelid. Precision matters more than spread here.
For the “11s” between your brows — either works well. This is where personal preference and provider judgment take over.
3. Units and dosing (the most confusing part)
Dysport and Botox use completely different unit scales. They are NOT interchangeable.
The typical conversion is approximately 2.5 to 3 Dysport units for every 1 Botox unit. So a forehead treatment that uses 20 units of Botox would use 50 to 60 units of Dysport — for the same clinical effect.
This is not a quality difference. It’s a measurement difference. Like comparing miles and kilometers — different numbers, same distance. The total treatment cost is generally comparable. If someone tries to sell you on Dysport being “cheaper per unit,” make sure they’re comparing total treatment cost, not per-unit price. The math only works when you account for the conversion ratio.
4. How it feels
This is subjective — and every patient is different. But there’s a consistent theme in our practice:
Many patients describe Dysport as feeling lighter. The broader spread creates a softer transition between relaxed and unrelaxed muscle. Patients who’ve had Botox and then try Dysport on their forehead often say the result feels more “natural” — the forehead moves, just more smoothly.
Botox tends to feel more targeted. Patients who like precise, clean relaxation in specific areas — “I want this line gone” — often prefer Botox’s more defined effect.
Neither feeling is better. It’s a preference. And many patients never notice a difference at all.
5. How long it lasts
Both: Three to four months for most patients.
Some patients report Dysport wearing off slightly sooner. Others find it lasts just as long. The difference — if it exists — is individual. Your metabolism, muscle strength, and treatment area matter more than which product you used.
After years of treating with both products, our clinical observation is: duration is more about the patient than the product. If you metabolize neurotoxins quickly, you metabolize both of them quickly.
The Myths — Let’s Kill Them
“Dysport is just cheaper Botox”
No. Dysport is a different product with different characteristics. It costs less per unit because you need more units. The total treatment cost is comparable. Choosing Dysport because it’s “cheaper” misunderstands the dosing.
“Botox is the gold standard and everything else is second-tier”
Botox was first to market. That’s an advantage in brand recognition — not in clinical superiority. Dysport has its own extensive clinical data, its own FDA approval, and its own advantages (faster onset, broader spread). Being first doesn’t mean being best. It means being most recognized.
“Once you start one, you can’t switch”
Completely false. You can switch between Dysport and Botox freely. Many patients try both over the course of a year to see which they prefer. Some discover they prefer different products for different areas. Switching is safe, common, and sometimes revealing — you may not know your preference until you’ve experienced both.
“They last different amounts of time”
The clinical data shows comparable duration (three to four months). Individual variation exists, but it’s not a reliable difference between the two products. Don’t choose based on duration — choose based on the characteristics that actually differ (onset speed, spread pattern, feel).
“More units of Dysport means it’s stronger”
Nope. The unit scales are different. 50 units of Dysport ≠ 50 units of Botox. It’s the equivalent of about 20 units of Botox. The conversion ratio means the numbers look different on paper while the actual dose is comparable.
How We Use Both at Illume
Here’s what actually happens in practice — not in theory.
Forehead: We lean toward Dysport for most patients. The broader diffusion creates smoother, more natural-looking relaxation across the entire forehead. Patients who’ve tried both usually prefer Dysport here.
Crow’s feet: We lean toward Botox. The localized behavior keeps the product where we put it — relaxing the crow’s feet muscle without migrating toward the eyelid-lifting muscle. Precision matters around the eyes.
“11s” (glabellar lines): Either. Both are FDA-approved for this area and both produce excellent results. Patient preference and provider assessment determine the choice.
Lip flip: Either — only 4 to 8 units needed. Both work well for this micro-dose application.
Masseter / therapeutic: Either — higher unit counts, but both products are effective for TMJ relief, jaw slimming, and migraine prevention.
The common scenario: Dysport on the forehead + Botox for crow’s feet. In the same appointment. Each area gets the product that serves it best. This is only possible at a practice that carries both.
The Question Behind the Question
If you’re reading this, you’re probably not choosing between Dysport and Botox in the abstract. You’re choosing a provider — and you want to know if they understand the difference well enough to use both intelligently.
The answer at Illume is yes. Our team uses both products daily, understands the clinical differences, and selects the right product (or combination) based on your specific anatomy and each treatment area’s demands. Not based on which product we have in stock. Not based on which brand is paying us a bonus this quarter. Based on what gives your face the best result.
That’s the difference between a practice that carries one neurotoxin and a practice that carries two.

Frequently Asked Questions
Is Dysport or Botox better?
Neither is universally better. Dysport spreads more and works faster — ideal for broad areas like the forehead. Botox stays more localized — ideal for precise areas like crow’s feet. The best result often comes from using both in the same appointment, each in the area it serves best.
Can I switch from Botox to Dysport?
Yes — safe and common. Many patients try both to discover their preference. Some use both simultaneously (different areas, same visit). Your provider adjusts dosing since the unit scales are different.
Does Dysport cost less than Botox?
Per unit, yes. But you need 2.5-3x more units of Dysport. Total treatment cost is generally comparable. Compare total cost, not per-unit price.
Which lasts longer?
Clinical data shows both lasting 3-4 months. Individual variation exists but is more about your metabolism than the product. Neither has a reliable duration advantage.
Is it true Dysport kicks in faster?
Yes — most patients see Dysport results in 2-3 days vs 3-5 for Botox. If timing matters (pre-event treatment), Dysport has the edge.
Do you carry both at Illume?
Yes. We use both daily and select based on treatment area and patient anatomy. Many patients receive Dysport and Botox in the same appointment — different products for different facial zones. IllumèNaughty Beauty Bank members receive 14% off both.
The Best Choice Is an Informed One
You don’t need to pick a side. You need a provider who understands both products well enough to pick for you — area by area, appointment by appointment, based on your face and your goals.
That conversation takes about fifteen minutes. And it’s the single most useful thing you can do with the “Dysport vs Botox” question.
