Ask five people which lasts longer, Botox or Dysport, and you’ll probably get five different answers. Most of them are repeating something they heard from a friend, not something backed by an actual study.
At Lumea Med Spa, this is one of the most common questions we get in a first consultation. Clients have usually read something online, or a friend swears one brand held up longer than the other, and they want to know which one is actually right for their face. The honest answer is that Botox and Dysport are both very good at what they do, but they aren’t the same product, and the differences matter more in certain situations than others.
This guide breaks down how these two treatments actually compare on speed, duration, dosing, and cost, using their FDA labeling and published research rather than salon folklore.
What Botox and Dysport Actually Are
Botox and Dysport are both forms of botulinum toxin type A, the same class of protein that temporarily blocks nerve signals to a muscle so it can’t contract as forcefully. That’s what softens the fine lines caused by repeated facial movement, like frown lines or crow’s feet.
Botox, known chemically as onabotulinumtoxinA, comes from AbbVie and has been used cosmetically since it received FDA approval for glabellar lines in 2002. Dysport, or abobotulinumtoxinA, is made by Ipsen and received its own FDA approval for glabellar lines in 2009.
Both are purified proteins derived from the same bacterium, but they’re manufactured differently, which changes their molecular size, the way they’re formulated, and how they behave once injected. That’s the root of nearly every practical difference between them.
Botox vs Dysport: Units Aren’t Interchangeable
This is the part that trips up most people researching these treatments online. A unit of Botox and a unit of Dysport are not the same amount of active product, so you can’t compare pricing or dosing by unit count alone.
The commonly cited conversion is roughly one Botox unit for every two and a half units of Dysport, meaning a treatment that takes 20 units of Botox might take closer to 50 units of Dysport to achieve a similar effect. According to a Drugs.com comparison of the two treatments, dosages are never a straight swap between the products, no matter how the math looks on paper.
This matters when you’re comparing quotes. A per unit price for Dysport that looks cheaper than Botox can still add up to a similar or even higher total cost once you factor in how many units your treatment actually needs, which is a big part of why unit price alone is a misleading way to shop for either treatment.
Which Areas Each One Is Actually Approved to Treat
Here’s a difference that rarely comes up in casual comparisons but shows up directly in the FDA prescribing information for each product. Botox Cosmetic is approved to treat glabellar lines, lateral canthal lines (crow’s feet), and forehead lines, all three areas most people associate with a classic Botox treatment.
Dysport’s cosmetic approval, according to its own FDA label, currently covers only glabellar lines in adults under 65. That doesn’t mean providers never use it off label for other areas, since off label use is common and legal in medical practice, but it does mean Botox carries a broader approved indication list for facial aesthetics on paper.
If you’re mainly treating the elevens between your brows, this distinction may not change your decision much. If you’re looking at a combination treatment across your forehead, brows, and crow’s feet in one visit, it’s worth asking your provider directly how they plan to approach areas outside a product’s specific approval.
How Fast Each One Kicks In
Onset speed is one of the more consistent differences reported between the two treatments. Dysport is often described as taking effect faster than Botox, sometimes showing visible softening within two to three days compared to Botox’s typical three to seven day window.
A Drugs.com review of clinical comparisons between the two noted that Dysport worked more quickly and with less reported injection discomfort in at least one head to head trial, though it’s worth noting that much of the comparative research in this space has been funded by the companies that make these products. That doesn’t make the findings false, but it’s a reason to treat any single study as one data point rather than the final word.
If you have an event coming up in a few days rather than a couple of weeks, onset speed is a legitimate reason to bring Dysport into the conversation with your provider.
How Long Results Actually Last
This is the question most people are really asking when they compare the two. In practice, both treatments tend to last around three to four months for most clients, and the difference in average duration between them is smaller than most marketing suggests.
Some clients report Dysport results tapering off slightly sooner, others say the opposite, and a meaningful amount of that variation comes down to individual metabolism, muscle strength, and how many units were used rather than the brand itself. If longevity is your top priority, the more useful conversation is usually about dosing and injection technique, not which logo is on the vial.
Consistent treatment on a three to four month cycle, regardless of which product you choose, is still the most reliable way to maintain results over a full year. Our guide to wrinkle treatment options in Miami covers how to think about that cycle alongside other in office options.
Diffusion: Why Some Providers Prefer One Product for Certain Areas
Diffusion refers to how far the toxin spreads from the exact injection point once it’s placed under the skin. Dysport’s molecule is generally considered smaller and more prone to spreading a bit further than Botox’s, which can be an advantage or a drawback depending on where it’s injected.
For a broad, flat area like the forehead, a bit of extra spread can actually help create a more even result across several injection points. For a precise area close to the eye, like crow’s feet, that same spread is exactly why some providers lean toward Botox instead, since less diffusion means a lower chance of the effect drifting toward the eyelid.
This is one of the clearest cases where the right product depends on the treatment area, not on which one is objectively stronger.
Botox vs Dysport: Cost in Miami
Pricing for both products in Miami tends to land in a similar range once you account for the unit conversion difference. A provider might charge a lower per unit rate for Dysport, but since a treatment typically needs more Dysport units to match a Botox dose, the total cost for a given area often comes out close to comparable.
The bigger cost variable in Miami is still the same one that applies to any neurotoxin treatment, meaning injector experience and practice overhead, not the specific brand in the syringe. If you want a full look at what actually moves the needle on Botox pricing specifically, that’s covered in detail in our Botox cost guide.
Who Tends to Do Well With Dysport
Clients treating a larger, flatter area like the full forehead, or who want to see results show up in a couple of days rather than a week, often gravitate toward Dysport once they understand the tradeoffs. It can also be a reasonable option for clients who’ve built up some resistance to Botox after years of treatment, since switching products occasionally helps if results have started to feel less predictable.
Who Tends to Do Well With Botox
Clients treating crow’s feet, forehead lines, and glabellar lines together in one visit often stick with Botox simply because it carries FDA approval across all three areas. It’s also the more established option for functional, non wrinkle uses, like the jaw slimming approach covered in our guide to masseter Botox in Miami, where precise, limited diffusion is part of what makes the treatment work well.
If you’ve never tried either product, Botox’s longer track record and wider body of published research make it a reasonable default starting point, with Dysport as a natural option to explore later if you want to compare how your face responds.
Neurotoxins Aren’t Your Only Option
Botox and Dysport both work by relaxing muscle movement, which means they’re built for dynamic wrinkles caused by repeated expressions, not volume loss. If what’s bothering you is more about lost fullness in the cheeks or under the eyes, a neurotoxin isn’t going to solve that on its own. Our Botox versus fillers comparison breaks down which concerns actually call for which category of treatment, since a lot of disappointing results trace back to choosing the wrong tool for the job rather than the wrong brand.
Safety and Who Should Think Twice Before Either One
Both products carry the same general safety profile, since they’re the same class of toxin with a long track record of use. Common side effects include mild bruising, a small amount of swelling at the injection site, and an occasional headache in the first day or two, and most of that resolves on its own within a week.
Neither treatment is recommended during pregnancy or while breastfeeding, and both carry a boxed warning about the toxin potentially spreading beyond the treatment area in rare cases, which is why choosing an experienced, licensed injector matters more than choosing a brand. Clients with certain neuromuscular conditions, like myasthenia gravis, should talk to their physician before considering either product, and a thorough consultation should always include a real conversation about your medical history rather than a quick checklist.
If you’re new to neurotoxin treatments altogether, starting with a smaller, conservative dose and building from there over a couple of sessions is generally safer than going all in on your first visit, regardless of which product you choose.
How to Actually Decide Between the Two
Most clients don’t need to walk into a consultation with a firm answer already picked out. A good injector will ask about your goals, look at how your specific muscles move, and factor in your timeline before recommending one product over the other.
If you’ve never had either treatment, price and brand recognition shouldn’t be the deciding factor. The injector’s experience with the specific product, and how closely they assess your face before recommending a dose, will affect your result far more than which name is on the box. Bring your priorities to the conversation, whether that’s speed of onset, a specific area you want treated, or wanting to match a friend’s results, and let that guide the discussion rather than picking blind based on marketing.
Caring for Your Skin Between Treatments
Whichever product you choose, keeping your skin calm in the days after injection matters more than people expect. A gentle, non irritating cleanser like our refining foam cleanser is a simple way to avoid disrupting the injection sites while your results settle in over the following week or two.
What This Looks Like at Lumea
At Lumea Med Spa, we don’t walk you in the door and hand you a menu with two logos on it. Every consultation starts with a look at your specific concerns, the areas you want treated, and how quickly you need to see results, and we talk through which product actually fits that picture.
Our Kendall and Dadeland team treats this decision the way it should be treated, as a clinical judgment based on your face rather than a coin flip between two brand names. Schedule a consultation with our Miami team to talk through your options and get a plan built around your goals.
Frequently Asked Questions About Botox vs Dysport
Does Dysport hurt more or less than Botox?
Most clients describe both as a quick, minor pinch rather than significant pain. Some comparative research has suggested Dysport injections are reported as slightly less uncomfortable, though this varies a lot by individual and by injection site.
Can I switch from Botox to Dysport or the other way around?
Yes. Many clients try both over time to see which one their face responds to best. There’s no medical reason you need to stick with one brand for life, and switching occasionally can even help if you feel like your results have plateaued.
Is Dysport actually cheaper than Botox?
Not usually, once you account for the fact that a Dysport treatment needs roughly two and a half times as many units to match a Botox dose. The per unit price looks lower, but the total cost for a comparable result tends to land close to the same range.
How many units of Dysport do I need if I usually get a certain amount of Botox?
A common starting point is multiplying your usual Botox unit count by roughly two and a half, though your provider should still assess your muscle strength and goals directly rather than applying a flat formula. This is exactly the kind of detail worth confirming at your consultation rather than guessing at home.
