Botox vs Dysport vs Xeomin: which one, and does it matter?

Botox, Dysport and Xeomin are all botulinum toxin type A. The differences between them are real, but they are differences of formulation, dosing units and diffusion, not differences of category. For most people in most areas, the dose and the injector matter more than the brand. If a clinic tells you one of the three is dramatically superior, ask them to explain why for your specific muscle and your specific goal.

We carry all three at our Bradford clinic, which is the only reason we can write this honestly. A clinic that stocks one brand has an obvious incentive to tell you that brand is best.

All three products contain the same active molecule

Botulinum toxin type A is a purified protein that temporarily blocks the nerve signal telling a muscle to contract. Botox, Dysport and Xeomin all contain it, under different generic names, because the manufacturing and formulation differ: Botox is onabotulinumtoxinA (AbbVie), Dysport is abobotulinumtoxinA (Ipsen/Galderma), and Xeomin is incobotulinumtoxinA (Merz). The active molecule is the same in all three. What changes is what surrounds it in the vial and how the product is measured.

The units are not interchangeable, which is why per-unit prices cannot be compared

One unit of Dysport is not equivalent to one unit of Botox, so a lower per-unit price does not mean a cheaper treatment. Commonly used conversion ratios sit somewhere around 2.5 to 3 Dysport units for every 1 Botox unit, and that is a working rule of thumb rather than an exact equivalence. Botox and Xeomin units are generally treated as roughly comparable to each other. The practical consequence: if one clinic quotes you a per-unit price for Dysport and another quotes a per-unit price for Botox, those two numbers are not the same currency. Ask both clinics what the total cost is to treat the area you care about.

Xeomin is formulated without the accessory proteins found in the other two

Xeomin contains the active toxin without the complexing proteins that accompany it in Botox and Dysport, which is why it is sometimes described as a “naked” toxin. That is a genuine formulation fact rather than a slogan. What it means for any one patient over years of treatment is not settled, and it is a conversation to have with your prescriber rather than a reason to choose a product from a web page.

How far each product spreads depends on dilution and technique as much as brand

Dysport is widely described as spreading further from the injection point than the other two, and Xeomin as spreading the least. Those descriptions are a starting point, but how far any of these products travels is heavily influenced by how much saline it is diluted with and how the injector places it. Technique and dilution can easily outweigh brand. This is a reason to care more about who is injecting you than which box the product came out of.

If you have a cow’s milk protein allergy, Dysport is the one to avoid

Dysport contains a trace of lactose derived from cow’s milk, so it is contraindicated for people with a known allergy to cow’s milk protein. Botox and Xeomin both contain human serum albumin. Any known allergy to a product component, or a previous reaction to a botulinum toxin injection, is a reason to choose a different product or not to treat at all. Tell your injector about every allergy, including ones you think are irrelevant.

“My injections stopped working” usually has a simpler explanation than resistance

True antibody-mediated resistance to botulinum toxin exists but is uncommon in cosmetic dosing, and it is not the first thing we look for. Far more often, a disappointing result traces back to an underdose for the muscle mass in question, a treatment interval that has crept longer than you remember, a change in the area being treated, or an expectation that softened lines would disappear entirely. Photographs from your previous appointments settle this argument quickly, which is one practical reason to have your injector take them. If genuine non-response is suspected, a change of product is one of the options that gets discussed, alongside reviewing dose and interval.

We will not tell you how long your result will last

How long a neuromodulator result lasts varies with the dose used, the muscle treated, how strong that muscle is, how you metabolise the product and what you are comparing it to. Published brand-versus-brand comparisons have not produced a duration difference that we would consider decisive for an individual patient, and any clinic quoting you a confident number for your face before assessing it is guessing. Your injector will give you a realistic expectation at your appointment, based on the dose actually planned for you, and will adjust it after they have seen how you respond once.

How the choice gets made

Your injector chooses per area and per person, using the facts above: the dosing units, how far each product tends to travel at the dilution being used, any allergy, and how you have responded before. For a first-time patient with no particular constraint, any of the three is a reasonable starting point. The choice is made at your consultation, after your injector has watched how your muscles move, and nothing is drawn up until you have agreed the plan and the price.

All three are prescription medicines in Canada

Botox, Dysport and Xeomin are prescription drugs in Canada, which means a physician or nurse practitioner must assess you and authorise the treatment. Injections are performed by regulated health professionals; estheticians may not inject in Ontario. At Bradford Skin Clinic, Alex Dinovich, FNP-PHC, is a nurse practitioner and authorised prescriber, and our injectors are Registered Practical Nurses. If you are ever unsure who is treating you and under what authority, ask. A clinic that cannot answer that question clearly has told you something important.
