Botox vs Dysport vs Xeomin — What's the Real Difference?
The short answer: all three are FDA-approved botulinum toxin type A products, they all work the same way, and for most patients the choice does not change the outcome. Where they differ — onset, spread, protein content, price per unit — matters at the margins, not in the mirror.
This guide walks through what actually differs and what does not, so a "we only use Xeomin" or "we prefer Dysport" pitch at your consult is a claim you can evaluate on the merits. Built by a physician with over 20 years of experience in facial cosmetic surgery.
What they have in common
All four leading neuromodulators — Botox (onabotulinumtoxinA), Dysport (abobotulinumtoxinA), Xeomin (incobotulinumtoxinA), and Jeuveau (prabotulinumtoxinA) — are botulinum toxin type A products. They block the release of acetylcholine at the neuromuscular junction, which temporarily prevents the target muscle from contracting. The wrinkle that muscle was creating softens.
Daxxify (daxibotulinumtoxinA) is also a botulinum toxin type A, approved by FDA in 2022. Its formulation includes a proprietary peptide that appears to extend duration.
All are administered by injection with a fine needle. All are FDA-approved for cosmetic use in the glabellar area ("elevens" between the brows). Most are also approved for lateral canthal lines (crow's feet) and forehead lines. The average physician fee for a neuromodulator session in 2023 was $435 across all of these products, per ASPS (ASPS 2023 average surgeon fees).
What actually differs
Onset and duration
Multiple clinical summaries put the typical onset and duration at:
| Product | Onset | Typical duration |
|---|---|---|
| Botox | 5–7 days | 3–4 months |
| Dysport | 2–4 days | 3–4 months |
| Xeomin | 5–7 days | 3–4 months |
| Jeuveau | 3–5 days | 3–4 months |
| Daxxify | 1–2 days | ~6 months (up to 9 in some patients) |
Individual results vary with muscle strength, dose, gender, metabolic rate, and injection precision. Dysport's faster onset is real but small — 2–3 days earlier than Botox on average — and rarely changes the practical experience.
Diffusion and spread
The three "legacy" products diffuse slightly differently after injection. Xeomin spreads the least (roughly a dime-sized area of effect per injection point), Botox somewhat more (roughly penny-sized), Dysport the most (roughly quarter-sized). This matters for:
- Large muscle groups where broader diffusion is helpful (Dysport is often chosen for the forehead for this reason).
- Small, precise areas near critical structures where narrow diffusion is safer (Xeomin can be preferable near the brow or around the eye).
For a standard glabellar treatment, the difference is essentially invisible in the mirror.
Protein content and antibody resistance
Botox and Dysport are formulated with accessory proteins that surround the neurotoxin. Xeomin is not — it is often marketed as the "naked toxin" formulation. In theory, the accessory proteins can trigger the immune system to develop neutralizing antibodies, which over time make repeated treatments less effective.
In practice, antibody resistance is uncommon in patients who receive standard cosmetic doses. It matters most for:
- Patients who have already developed diminished response to Botox after years of use, where switching to Xeomin can restore effect.
- Patients receiving high therapeutic doses (much larger than cosmetic doses) for medical conditions.
For a first-time cosmetic patient, this is not a decisive factor.
Allergen content
Dysport contains lactose and cow's milk protein. Patients with a documented severe cow's milk allergy should avoid it. Xeomin and Botox do not contain this allergen.
Why units are not interchangeable
This is the single most important thing to understand before comparing prices.
- Botox and Xeomin units are roughly 1:1 equivalent. 20 units of Botox and 20 units of Xeomin do roughly the same amount of work.
- Dysport units are different. Approximately 2.5 to 3 units of Dysport equal 1 unit of Botox in clinical effect.
This means a clinic advertising "$4 per unit of Dysport" is not automatically cheaper than one advertising "$12 per unit of Botox." To treat the glabella with Dysport, you need roughly 50 to 60 Dysport units instead of 20 Botox units. The Dysport session at $4 a unit costs $200 to $240; the Botox session at $12 a unit costs $240. In a fair comparison the prices are close.
For a fair price comparison, always compute the cost per treatment area, never the cost per unit alone.
Daxxify: the longevity trade
Daxxify's main claim is duration — around 6 months compared to 3–4 months for the others. That is real. What is less discussed is the trade:
- Higher cost per treatment. Because you are paying for more months of effect, per-treatment cost is meaningfully higher.
- Slower to fix a bad result. If the injection produces asymmetry, a droop, or a look you dislike, you wait through more of it before the effect wears off. With Botox, you wait 3 months. With Daxxify, potentially 6.
Daxxify is a reasonable pick for a patient with a long track record of predictable Botox results who wants fewer visits. It is a poor first-time choice.
How to compare a real quote
When a clinic recommends one product over another, ask three questions:
- Why this product for this muscle? ("Because we get a rebate" is a wrong answer. "Because I want narrower diffusion near your brow" is a correct one.)
- What is the price per treatment area for the recommended dose? Not per unit. Per area.
- What has been your previous product and response? If you have a history of good results on Botox, switching brands should have a clinical reason, not a marketing one.
Who should skip this comparison
- You are a first-time patient with no product preference and no allergies. Whichever the clinic is best-trained with is the right pick. Injector skill matters more than brand choice.
- You already get consistent results with your current product. Switching creates uncertainty, and the difference in the mirror is small. Stay.
- You are shopping on per-unit price alone. The unit comparison across brands is misleading. Compare by treatment area or by session.
The rule that survives every quote
The molecule is the same. The results in the mirror are essentially the same. What differs is a small set of technical characteristics that a skilled injector will use to match product to muscle. If your clinic cannot articulate why they are recommending one over another beyond "we use Xeomin," that is a marketing preference, not a clinical one. Ask.
Frequently asked questions
Is one of Botox, Dysport, or Xeomin better than the others?
For most patients, no. All three are FDA-approved botulinum toxin type A products with the same mechanism of action. The differences — onset speed, diffusion pattern, protein content — are small and matter mainly for specific muscle groups and specific patient histories, not for the average forehead or glabellar treatment.
How do they differ in onset and duration?
Onset is 3–5 days for Dysport, 5–7 days for Botox and Xeomin. Duration is 3–4 months for all three in most patients. Daxxify (a newer product) has onset of 1–2 days and duration of about 6 months, which is why it costs more. Individual results vary with muscle strength, metabolism, and dose.
Are the units the same across brands?
No. This is the biggest confusion. Dysport units are not equivalent to Botox units. Roughly 2.5 to 3 units of Dysport equal 1 unit of Botox. A clinic quoting "$4 per unit of Dysport" is not automatically cheaper than one quoting "$12 per unit of Botox" — you need 2.5x to 3x as many units of Dysport for the same effect.
What is Xeomin's "naked toxin" advantage?
Xeomin is manufactured without accessory proteins that surround the toxin in Botox and Dysport. In theory, this reduces the chance of the immune system producing neutralizing antibodies that would make future treatments less effective. In practice, antibody resistance is uncommon with any of the three, and the difference matters most for patients who have already developed reduced response to Botox.
Why do some clinics recommend a specific brand?
Legitimate reasons include your prior response, the specific muscle being treated, or a clinical rationale like allergen avoidance (Dysport contains lactose and cow's milk protein, so patients with severe cow's milk allergy should avoid it). Less legitimate reasons include manufacturer volume discounts and loyalty rebates, which incentivize a clinic to push whichever product gives them the biggest margin.
