Botox vs Dysport vs Xeomin: Which Is Best?
All three are botulinum toxin type A products that relax muscles to smooth dynamic wrinkles — but they differ in formulation, spread, onset speed, and pricing. Botox (Allergan) is the most recognised name. Dysport (Galderma) spreads wider and may kick in faster. Xeomin (Merz) is a “naked” toxin with no complexing proteins.

In simple terms: Botox = gold standard, most predictable. Dysport = faster onset, wider spread (great for forehead). Xeomin = pure toxin, no antibody risk from complexing proteins. All produce similar results in experienced hands — the difference is subtle, not dramatic.
Side-by-Side Comparison
| Feature | Botox (Allergan) | Dysport (Galderma) | Xeomin (Merz) |
|---|---|---|---|
| Active ingredient | OnabotulinumtoxinA | AbobotulinumtoxinA | IncobotulinumtoxinA |
| Complexing proteins | Yes — contains accessory proteins | Yes — contains accessory proteins | No — “naked” pure toxin, no complexing proteins |
| Onset | 3–7 days; full effect at 2 weeks | 2–5 days; may kick in slightly faster | 3–7 days; similar to Botox |
| Spread / diffusion | Stays close to injection point — precise placement | Wider spread — covers larger areas with fewer injection points | Stays close to injection point — similar to Botox |
| Best for | Precise areas — frown lines, crow’s feet, bunny lines, lip flip | Broad areas — forehead, masseter, hyperhidrosis, trapezius | Patients who have developed resistance to Botox or Dysport, or those wanting a pure formulation |
| Duration | 3–6 months | 3–6 months (some report slightly shorter) | 3–6 months |
| Unit conversion | 1 unit Botox | ~2.5–3 units Dysport = 1 unit Botox | 1 unit Xeomin = 1 unit Botox |
| Antibody resistance risk | Possible with repeated use (complexing proteins may trigger) | Possible with repeated use (complexing proteins may trigger) | Lower risk — no complexing proteins to trigger antibody formation |
| Storage | Requires refrigeration | Requires refrigeration | Room temperature — no cold chain needed |

Frequently Asked Questions
What is the difference between Botox, Dysport, and Xeomin?
All three are botulinum toxin type A products that relax muscles. Botox is the most widely used with the longest track record. Dysport spreads wider and may work slightly faster — good for broad areas like the forehead. Xeomin is a “naked” toxin with no complexing proteins, which may reduce the risk of developing antibody resistance.
Which works fastest?
Dysport typically shows results within 2–5 days, slightly faster than Botox and Xeomin which take 3–7 days. All three reach full effect at approximately 2 weeks. If you need results for an event, Dysport may give you a head start of a day or two.
Which lasts longest?
All three last approximately 3–6 months. Some patients report Dysport wearing off slightly faster in certain areas, while others find it lasts the same. Duration varies more by area treated and individual metabolism than by brand. See how many units of Botox for area-specific guidance.
Why would I choose Xeomin over Botox?
Xeomin is a “naked” toxin — it contains no complexing proteins. This may be important if you have developed antibody resistance to Botox or Dysport (where the treatment stops working as well over time). The lack of complexing proteins means a lower theoretical risk of your immune system building resistance. It is also stored at room temperature, which some clinics prefer.
Are units the same across brands?
Botox and Xeomin use a 1:1 unit conversion — 20 units of Botox equals approximately 20 units of Xeomin. Dysport uses a different measurement — roughly 2.5–3 units of Dysport equals 1 unit of Botox. This means Dysport numbers look higher but the overall cost is usually comparable.
Can I switch between brands?
Yes. You can switch between Botox, Dysport, and Xeomin. In fact, switching brands is sometimes recommended if you feel one is becoming less effective — this can help if antibody resistance is developing. Dr Azra Vaziri can advise on whether switching brands may benefit you.
Which does Dr Azra use?
Dr Azra uses all three brands and selects based on the treatment area, patient history, and specific goals. Botox for precision work, Dysport for broad areas, and Xeomin for patients who have used toxins for many years or who prefer a pure formulation. The choice is made during your consultation.
Do they all have the same safety profile?
Yes — all three are FDA-approved botulinum toxin type A products with well-established safety profiles when administered by a qualified practitioner. Side effects (mild bruising, temporary headache) are similar across all brands. See Botox aftercare for post-treatment guidance and our wrinkle treatment guide for the full range of options.
