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.

This guide explains the real differences and how Dr Azra Vaziri selects between them. For filler vs Botox comparisons, see Filler vs Botox. Related: How Many Units of Botox · Botox Aftercare · Preventative Botox · Botox Price Dubai.

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

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.

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.

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.

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.

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.

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.

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.

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.
