Botox vs Dysport vs Xeomin: Triple Comparison of Neurotoxins
Botox, Dysport, and Xeomin all use botulinum toxin to smooth wrinkles, but they differ in formulation, spread, onset, and pricing. Here's how to choose.
Botox vs Dysport vs Xeomin: Understanding Your Neurotoxin Options
When most people think of wrinkle-relaxing injections, they think of "Botox" — but Botox is actually just one of three FDA-approved botulinum toxin type A products available for cosmetic use. Dysport and Xeomin are equally effective alternatives, each with distinct characteristics that may make them a better fit for certain patients or treatment areas.
All three products work through the same fundamental mechanism: they temporarily block the nerve signals that cause targeted muscles to contract, thereby smoothing the wrinkles created by repeated facial expressions. However, differences in their formulation, onset time, diffusion patterns, and dosing can influence which product is optimal for a given patient.
The Three Neurotoxins at a Glance
Botox (OnabotulinumtoxinA)
Manufactured by Allergan (AbbVie), Botox was the first botulinum toxin approved for cosmetic use in 2002. It remains the most widely recognized and most frequently used neurotoxin worldwide. Botox contains the botulinum toxin complexed with protective proteins (complexing proteins), which add molecular weight and may influence how the product behaves once injected.
Dysport (AbobotulinumtoxinA)
Manufactured by Galderma, Dysport received FDA approval for cosmetic use in 2009 (though it had been used in Europe since the 1990s). Dysport also contains complexing proteins but has a smaller molecular size than Botox. This smaller molecular structure contributes to its tendency to diffuse more broadly from the injection site.
Xeomin (IncobotulinumtoxinA)
Manufactured by Merz, Xeomin was FDA-approved for cosmetic use in 2011. Its distinguishing feature is that it is a "naked" neurotoxin — the manufacturing process removes all complexing proteins, leaving only the pure 150-kDa botulinum toxin molecule. This purity may reduce the risk of developing antibody resistance over time.

Key Differences Explained
Onset Speed
Dysport is widely reported to take effect slightly faster than Botox and Xeomin. Many patients notice results within 24 to 48 hours, compared to 3 to 5 days for Botox and Xeomin. This faster onset can be advantageous for patients who want results before an upcoming event, though all three products reach their peak effect at approximately the same time (10 to 14 days).
Diffusion and Spread
Dysport's smaller molecular size causes it to spread more broadly from the injection point than Botox or Xeomin. This characteristic can be either an advantage or a disadvantage:
- Advantage: Broader spread is beneficial for treating large areas like the forehead, where even coverage across a wide surface is desirable. Fewer injection points may be needed, and the result can appear smoother.
- Disadvantage: In areas where precision is critical — such as around the eyes or near the brow — excessive spread could affect unintended muscles, potentially causing drooping or an unnatural appearance.
Skilled injectors account for Dysport's diffusion by adjusting their injection technique, placement, and dilution accordingly.
Dosing Units
Botox and Xeomin use the same unit-to-unit equivalence — 20 units of Botox produces roughly the same effect as 20 units of Xeomin. Dysport units are not equivalent; approximately 2.5 to 3 units of Dysport are needed to match 1 unit of Botox or Xeomin.
This dosing difference means that while Dysport's per-unit cost is lower, the total cost per treatment area is comparable across all three products when unit equivalences are accounted for.
Antibody Resistance
With any botulinum toxin product, there is a theoretical risk that the body may develop neutralizing antibodies that reduce the product's effectiveness over time. This concern is more relevant for patients receiving high doses for medical conditions (like spasticity) than for typical cosmetic use.
Xeomin's lack of complexing proteins may confer a slight advantage here. Since antibodies can form against both the active toxin and the complexing proteins, a "naked" formulation presents fewer potential targets. Some practitioners recommend Xeomin for patients who have noticed diminishing results from Botox or Dysport, or for those receiving frequent treatments.
Choosing by Treatment Area
Forehead Lines
All three products work well. Dysport's broader spread can be advantageous here, potentially providing smoother, more even coverage across the wide forehead surface with fewer injection points. Many injectors favor Dysport for this area.
Frown Lines (Glabellar Lines)
All three are FDA-approved specifically for this area and perform comparably. Botox and Xeomin's more localized spread provides precise control over the corrugator and procerus muscles without affecting nearby areas. Dysport also works well when injected by experienced practitioners who adjust for its diffusion.
Crow's Feet
Precision is important here to avoid affecting the muscles that control eye opening and lower eyelid support. Botox and Xeomin's more contained spread makes them popular choices. Dysport can be used effectively with careful dosing and placement, and some injectors prefer it for a softer, more gradual blending effect.
Brow Lift
A subtle brow lift can be achieved by strategically relaxing the muscles that pull the brow downward (corrugator, orbicularis oculi) while preserving the muscles that elevate it (frontalis). This technique requires precision, making Botox and Xeomin popular choices. Dysport may spread into the frontalis if not placed carefully, potentially blunting the desired lift.
Bunny Lines, Chin, and Neck
These areas require precise, targeted injections with controlled spread. Botox and Xeomin are commonly used. Dysport can be effective with experienced technique and conservative dosing.
Price Comparison
While per-unit pricing varies by practice and location, the cost per treatment area is remarkably similar across all three products when unit equivalence is considered:
- Forehead treatment: $250–$600 for all three
- Frown lines: $200–$400 for all three
- Crow's feet: $200–$400 for all three
- Full upper face: $400–$800 for all three
Dysport and Xeomin are sometimes priced slightly lower per treatment area than Botox, though this varies by practice. Some clinics use competitive pricing on one product to attract new patients. The price difference is typically not significant enough to be the primary deciding factor.
Switching Between Products
Patients can switch between Botox, Dysport, and Xeomin without safety concerns. Common reasons for switching include:
- Diminishing results from the current product (trying a different formulation may restore effectiveness)
- Cost considerations (taking advantage of promotions or rewards programs)
- Onset preference (switching to Dysport for faster results)
- Antibody concerns (switching to Xeomin for its pure formulation)
- Treatment refinement (trying a different product to achieve a slightly different aesthetic result)
When switching products, communicate openly with your injector about your history, what you liked and disliked about previous treatments, and your goals for the new product.
Loyalty and Rewards Programs
All three manufacturers offer patient rewards programs that can meaningfully reduce costs over time:
- Botox: Allē (formerly Brilliant Distinctions) offers points on Botox and other Allergan products
- Dysport: Aspire Galderma Rewards provides savings on Dysport and other Galderma products
- Xeomin: Xperience+ offers rebates and savings on treatments
Enrolling in the relevant program can save $50 to $100 or more per treatment session, making these programs worth investigating regardless of which product you choose.
The Bottom Line
Botox, Dysport, and Xeomin are all safe, effective, FDA-approved options for smoothing dynamic wrinkles. Their core mechanism is identical, and in experienced hands, all three deliver excellent results. The differences — Dysport's faster onset and broader spread, Xeomin's pure formulation and potential antibody resistance advantage, and Botox's long track record and precision — are relatively subtle and matter most in specific clinical situations.
The most important factor in your results is not which product is used, but who is injecting it. Choose a board-certified dermatologist, plastic surgeon, or experienced aesthetic provider who understands facial anatomy, has extensive injection experience, and can recommend the optimal product for your specific treatment areas and goals. A skilled injector with any of these three products will outperform an inexperienced one with the "best" product every time.
