Botox vs Dysport vs Xeomin: How to Choose
This article has been written by Kassandra Marin, RN BSN
Three products, one active ingredient, and a lot of confident opinions online.
Botox, Dysport and Xeomin are all botulinum toxin type A, and all three do the same basic job: relax the specific muscle that folds your skin into a line.
The differences between them are real but small, and they matter less than who is holding the syringe. Here is what actually separates them, and how the choice gets made when it is made well.
All Three Are the Same Active Toxin
Every one of these is botulinum toxin type A, approved by the FDA for the temporary improvement of facial lines. None of them is a knock-off of another, and none is a generic version of
Botox.
What differs is the formulation around the toxin, the dosing scale, and the specific facial areas each one is approved to treat. Those differences are the whole conversation, and none of them is large.
Units Do Not Convert Between Them
This is the single most useful thing to know, and the thing most often gotten wrong. A unit of one product is not a unit of another. The dosing scales are set by different laboratory assays and they are not comparable.
Each product says so in its own FDA prescribing information, in almost identical language:
"Units of biological activity of BOTOX Cosmetic cannot be compared to nor converted into units of any other botulinum toxin products."
"The potency units of DYSPORT are not interchangeable with other preparations of botulinum toxin products."
"Units of biological activity of XEOMIN cannot be compared to or converted into Units of any other botulinum toxin products."
The practical consequence is simple. A price per unit tells you nothing until you know which product it is. A Dysport quote with a lower per-unit number is not automatically cheaper, because a Dysport treatment uses a different number of units to do the same work.
Compare the total for the treatment, never the number next to the word "unit".
How to Compare Two Quotes
If you are weighing two places against each other, the per-unit number is the wrong thing to line up. Two honest quotes can look very different on paper and cost the same in the chair.
Ask each one the same three questions. Which product is it, how many units will you use for my areas, and is a two-week follow-up included.
A quote that answers all three is a real number you can compare. A quote that only gives you a price per unit is not, and you should treat the gap as information.
How They Differ in Practice
Reduced to what a patient would actually notice, the differences are small and mostly about timing:
| Botox | Dysport | Xeomin | |
|---|---|---|---|
| Active ingredient | Botulinum toxin type A | Botulinum toxin type A | Botulinum toxin type A |
| Formulation | Toxin with accessory proteins | Toxin with accessory proteins | Toxin only, no accessory proteins |
| Spread | Most precise | Spreads slightly more | Precise |
| Onset | Effects begin one to two days after injection | Often noticed a little sooner | Softening typically begins day 3 to 4 |
| Typical duration | About 3 to 4 months | About 3 to 4 months | About 3 to 4 months |
| FDA cosmetic areas | Frown lines, crow’s feet, forehead lines, platysma bands | Frown lines, in adults under 65 | Frown lines, forehead lines, crow’s feet |
| Units | Not convertible to any other product | Not convertible to any other product | Not convertible to any other product |
Onset and Duration, in Plain Terms
Onset is where the small differences show up first. Botox usually begins to soften the treated muscle within a day or two, Dysport is often noticed a touch sooner, and Xeomin tends to come in around day three or four.
None of that changes where you end up. By two weeks all three have done their work, which is why your follow-up sits at the two-week mark no matter which one you had.
Duration lands in the same place too. For most people all three hold for about three to four months, and how long yours lasts has more to do with your muscles and your metabolism than with the label on the vial.
When Each One Makes Sense
Botox for Precision
The most predictable option for small, targeted areas where you want the effect to stay exactly where it was placed. It is also the one with the longest track record, which matters to some people and not to others.
Dysport for Broad Areas
The slightly wider spread is an advantage across a large forehead, where the goal is an even softening rather than a series of precise points. It also tends to show up a little sooner.
Xeomin for a Cleaner Formula
Xeomin is the active molecule with no accessory proteins around it. That is the reason it comes up for people whose results from another product have faded over years of treatment.
Matching the Product to Your Goal
Most of the time the product follows the goal, not the other way around. Three patterns cover the majority of cases.
If you want a small, defined area held exactly where it was placed, precision is the priority. If you are softening a broad forehead and want an even result rather than a set of points, a little more spread is an asset.
And if a product you have used for years has slowly stopped giving you the result it used to, the formula without accessory proteins is the one worth trying next.
Myths Worth Dropping
A few beliefs come up in almost every consultation, and all of them cost people money or results.
- The newest product is the best one. Newer means newer, not stronger, and the right choice is the one that fits your face and your history.
- Dysport is the budget option. It only looks cheaper when you compare per-unit numbers that were never meant to be compared.
- Switching means starting from scratch. Your dose is converted to the new scale and adjusted from there, not reset to zero.
Switching Between Them
You can switch, and plenty of people do. The thing to expect is that the first treatment on a new product is a recalibration, not a repeat.
Your dose gets converted to the new scale, and your injector watches how you respond before settling on your numbers. Give it one full cycle before deciding whether the new one suits you better.
How the Choice Gets Made at Your Consultation
In practice the product is chosen after the assessment, not before it. Kassie looks at how your face moves, how strong the muscles are, which areas you want treated, and what you have responded to in the past.
If you have a preference, say so and you will get a straight answer about whether it fits. If you do not, you will get a recommendation with the reasoning attached rather than a product name on its own.
Nothing here is recommended because of what is in stock. Nobody at Soléa works on commission, and the product that gets suggested is the one that suits your face.
Frequently Asked Questions
Is one of them stronger than the others?
No. They are the same active toxin and the same strength of effect when dosed correctly. What differs is the dosing scale, so a bigger unit number does not mean a stronger treatment.
Which one lasts the longest?
For most people all three run about three to four months. Duration has more to do with your metabolism, your muscle strength and how consistently you treat than with which product you pick.
Is Dysport cheaper than Botox?
Not necessarily, and comparing per-unit prices will mislead you. The units are measured on different scales, so a Dysport treatment uses a different unit count. Compare the total for the treatment instead.
Why would I switch to Xeomin?
The usual reason is that another product has stopped working as well over years of treatment. Xeomin is the toxin without the accessory proteins, which is why it comes up in that conversation.
Can I have two different products in one appointment?
It is possible but rarely the right call for a first treatment. Using one product at a time makes it clear what is working, which is what your dosing gets built from.
How do I know which one is right for me?
You will get a recommendation at your consultation, based on how your face moves and what you are treating. The product matters less than the dosing and placement, which is the part that depends on your injector.
Is Botox the original one?
Botox was the first botulinum toxin type A approved for cosmetic use, which is why its name gets used as a catch-all for all three. Being first is a track record, not a guarantee that it is the right one for you.
Will anyone be able to tell which product I had?
No. A good result looks the same whichever of the three produced it, because the product does far less of the work than the dosing and placement do.
