Quick answer: Botox, Dysport and Xeomin are all botulinum toxin type A products that relax muscles to soften dynamic wrinkles. They are not interchangeable, because each has its own unit strength, so a unit of one is not a unit of another. In a randomised study of frown lines, Xeomin showed faster onset and longer duration than Botox and Dysport at the doses tested. Choice depends on the area, the result you want and your doctor’s experience, rather than brand alone. For the full treatment overview, see our Botox treatment page.

Many people ask which botulinum toxin is best. The answer is less about a single winner and more about how each product behaves and how your doctor uses it. This guide compares Botox, Dysport and Xeomin on the points that matter most, including onset, duration, units and how they are dosed.

What Botox, Dysport and Xeomin Have in Common

All three are purified botulinum toxin type A products. They work by blocking the nerve signals that tell a muscle to contract, so the overlying wrinkle softens. They are approved in many countries for frown lines, and they are used off-label for other areas such as crow’s feet and forehead lines, depending on the product and region.

How They Differ

Feature Botox (onabotulinumtoxinA) Dysport (abobotulinumtoxinA) Xeomin (incobotulinumtoxinA)
Unit strength Not interchangeable with other brands Not interchangeable with other brands Not interchangeable with other brands
Onset in frown lines About 5 days in one study About 5 days in one study About 3 days in one study
Duration in frown lines Shorter in the same study Shorter in the same study Longer in the same study
Typical use Widely used for lines in the upper face Widely used across the upper face; check your doctor’s preference for each area Often chosen for faster onset and longer effect

In a randomised, double-blind study, a single treatment of incobotulinumtoxinA (Xeomin) produced a faster onset and longer duration of effect for frown lines than onabotulinumtoxinA (Botox) and abobotulinumtoxinA (Dysport), using the doses in that study (randomised study of onset and duration of three botulinum toxin products). Because the doses and units differ, the findings do not mean one product is better in every case.

Why Units Cannot Be Compared Directly

Each product has its own potency and unit definition. The study above used different unit doses for each product, which is why it reports a dose ratio rather than a direct equivalence. Price per unit can look different between brands, but the number of units needed for the same result also differs, so compare the cost of a planned treatment rather than the unit price alone.

Onset and Duration in Practice

Across the upper-face literature, Dysport is often reported to start working within about 2 to 3 days, although in the head-to-head study above its onset was about 5 days, and durations are reported at around 3 to 6 months across studies (systematic review of abobotulinumtoxinA onset and duration in the upper face). Results for Botox and Xeomin also fall within a broadly similar window in practice, but individual timing varies.

How Your Doctor Chooses

  • The muscle and area being treated, such as frown lines, crow’s feet or forehead
  • The result you want, including how natural and how even
  • How quickly you want the effect and how long you want it to last
  • Your muscle strength and previous treatment response
  • The doctor’s experience with each product

In many cases, the product matters less than the technique and dose. A skilled injector can get good results from more than one brand.

Safety Is the Same Principle for All Three

Serious side effects are rare with any of these products when used by a trained doctor. Common effects include bruising, swelling and headache. Less common effects can include temporary droopy eyelids or asymmetry. Any product should be checked for registration and batch details before treatment, and you should avoid unregistered or unverified sources.

Frequently Asked Questions

Is Xeomin better than Botox?

In one randomised study, Xeomin had a faster onset and longer duration for frown lines at the doses tested. That does not automatically make it better for everyone, and the right choice depends on your goals and your doctor’s assessment.

Is Dysport cheaper than Botox?

Prices depend on the number of units needed, the area, the clinic and the doctor. Compare the total cost of a planned treatment, not the price per unit.

Can I switch between brands?

Some people do, but switching changes the dose and expected timing, so discuss it with your doctor first.

Which one is safest?

All three are used safely in clinical practice when administered correctly by a qualified doctor. Safety depends more on the injector, the dose and product authenticity than on the brand name.
