I get asked this question constantly — sometimes mid-treatment, sometimes during a consultation, sometimes as a text from a patient at 10pm. "Dr. Munib, should I get Dysport or Botox?"
The short answer is: it depends. And I mean that in the most useful way possible — not as a dodge, but because the right choice genuinely does depend on your facial anatomy, your treatment goals, how your body has responded to neuromodulators in the past, and a few other factors I'll walk you through here.
What I want to do in this post is take you inside the actual clinical thinking. Not just a generic side-by-side, but the real framework I use when deciding what's right for each patient I see here in Irvine.
This is the most important thing to understand before we get into the differences. Both Dysport and Botox are botulinum toxin type A. They work through the same mechanism: they temporarily block the signal between a nerve and a muscle, which prevents that muscle from contracting. No contraction, no wrinkle.
Neither one is "more natural" or "safer" in any meaningful clinical sense. Both are FDA-approved, both have decades of research behind them, and both — when administered correctly by a trained physician — produce beautiful, natural-looking results.
The differences between them are subtler than most marketing materials let on. But those differences do matter.
| Factor | Dysport® (by Galderma) | Botox® (by Allergan) |
|---|---|---|
| Onset | 2–3 days (often faster) | 3–7 days |
| Full results | ~7 days | 10–14 days |
| Duration | 3.5–5 months | 3–4 months (average) |
| Spread / Diffusion | Broader — covers more surface area | More localized, precise |
| Molecular size | Smaller protein complex | Larger protein complex |
| Unit dosing | ~2.5–3 units = 1 Botox unit | 1:1 reference standard |
| FDA approval (on-label) | Glabellar lines ("11s") | Glabellar, forehead, crow's feet |
| Loyalty program | Aspire Rewards (Galderma) | Brilliant Distinctions (Allergan) |
The most clinically meaningful difference between these two products, in my opinion, is diffusion — how far the product spreads from the injection point.
Dysport has a smaller molecular weight protein complex, which means it spreads more broadly through the muscle. This is a feature, not a flaw — in the right areas, it gives you a softer, more blended result with fewer injection points. It's one of the reasons many patients say their Dysport results look more natural.
Botox, with its larger protein complex, stays more localized. This precision is exactly what you want in areas where you need targeted effect — places where you don't want the toxin drifting.
"Think of Dysport as a wider brush and Botox as a fine-tipped pen. Both create beautiful results — you just choose the right tool for the area you're treating." — Dr. Sabeen Munib, MD
Here's how that translates to treatment zones:
When I tend to reach for Dysport:
When I tend to reach for Botox:
Yes — and this is one of the most consistent pieces of feedback I hear from patients who've tried both. Dysport tends to kick in within 2 to 3 days, whereas Botox typically takes 3 to 7 days before you start noticing anything, and up to 2 weeks for full results.
For patients who have something coming up — an event, a reunion, a trip — that difference can genuinely matter. I always tell patients to schedule at least 2 weeks out regardless, but if you're in a tighter window, Dysport gives you more predictability.
Duration-wise, Dysport holds up well — often 3.5 to 5 months, which is comparable to or slightly longer than Botox in many patients. That said, duration is highly individual. How active you are, how fast your metabolism runs, how expressive your face is — all of these things affect how long any neuromodulator lasts for you specifically.
Both products are priced per unit at Spectrum Skin Clinic. Because of the unit conversion difference, the per-unit price for Dysport may look lower on paper — but once you account for the higher number of units needed, the total cost of treatment is generally comparable between the two.
The bigger cost consideration isn't which brand you choose — it's how many units you need for your specific treatment areas, and how often you're coming in. That's highly individual, and it's something I'd rather discuss with you in person than try to quote on a blog post where I haven't seen your face.
What I can say is that we don't push one product over the other for financial reasons. We recommend what will give you the best outcome for your face.
When a new patient comes in for a neuromodulator treatment, the product choice isn't something I decide before I meet them. It's a conversation. Here's what I'm thinking through:
The honest truth is that most experienced injectors develop a preference shaped by years of watching how each product performs. My preference tends to lean toward Dysport for natural, blended results in larger zones — but I'll always use whichever product is genuinely right for the patient in front of me.
Neither. And I mean that. This isn't a diplomatic non-answer — it's clinically accurate. Both Dysport and Botox are excellent products with strong safety profiles, proven clinical outcomes, and highly satisfied patients behind them.
What differs is the context in which each one shines. Dysport's broader diffusion and faster onset make it excellent for large, expressive zones and for patients who want a softer first result. Botox's precision and broader FDA-approved indications make it the go-to for targeted treatments and for patients where predictability is the top priority.
"The right question isn't 'which product is better' — it's 'which product is better for your face and goals.' That's what we figure out together." — Dr. Sabeen Munib, MD

For many patients, yes — Dysport's broader diffusion produces a softer, more blended result across the forehead, which tends to look more natural. However, in patients who need very precise dosing near the brow, Botox's localized effect may be preferable. Dr. Munib assesses this during your consultation.
Absolutely — and there can be real benefits to rotating. Some patients develop tolerance to one product over time and find that switching refreshes their responsiveness. The dosing is simply converted (approximately 2.5–3 Dysport units per 1 Botox unit), and most patients transition seamlessly.
This concern comes up often. The answer is: not in the hands of an experienced injector. Dysport's diffusion is predictable and well-understood — the key is knowing where to place the injections and what dosing to use. Brow or lid ptosis (drooping) is a risk with any neuromodulator when injected imprecisely, not a unique risk of Dysport specifically.
Many patients find Dysport lasts slightly longer — 3.5 to 5 months compared to Botox's 3 to 4 months on average. That said, duration depends heavily on your metabolism, activity level, how expressive you are, and the area being treated. Dr. Munib can give you a more personalized estimate after evaluating you.
Per unit, Dysport often looks less expensive — but because you need more units to achieve the same effect, the total treatment cost is generally comparable. At Spectrum Skin Clinic, we price transparently: we tell you exactly how many units we're planning to use before we begin, so there are no surprises.
Yes. Dysport is part of the Aspire Rewards program by Galderma, which also covers Restylane fillers and Sculptra. Botox is part of Brilliant Distinctions by Allergan. We'll help you enroll and maximize your rewards at your appointment.
