Botox and Xeomin are both FDA-approved botulinum toxin type A neuromodulators that relax the muscles behind frown lines.
Botox and Xeomin are both FDA-approved botulinum toxin type A neuromodulators that relax the muscles behind frown lines. The defining difference is purity: Xeomin is the “naked toxin,” stripped of the complexing proteins Botox carries. They dose 1:1 with very similar results — Xeomin is cheaper and may carry a lower resistance risk, while Botox has a longer track record and more approvals.

The defining difference is purity: Xeomin is the “naked toxin,” stripped of the complexing proteins Botox carries. They dose 1:1 with very similar results — Xeomin is cheaper and may carry a lower resistance risk, while Botox has a longer track record and more approvals. Here’s the full comparison, then how to choose.
Both are botulinum toxin type A injectables that temporarily relax muscles to soften dynamic wrinkles, both are FDA-approved with comparable effectiveness and 1:1 dosing, and neither can be reversed — each wears off over time. Both are muscle relaxers, not volumizers: for lost volume you’d want dermal fillers instead, as covered in Botox vs dermal fillers.
This is the core distinction. Botox carries its active toxin inside a larger ~900 kDa complex of accessory proteins, while Xeomin is purified down to just the 150 kDa active molecule — nothing else. Those extra proteins serve no therapeutic purpose; they’re simply part of how the older products are manufactured. Functionally the two behave alike, which is why they dose 1:1, but the purity has two practical consequences: resistance and storage.
With repeated injections over years, a small number of people form antibodies against the complexing proteins in other toxins, which can make them less effective. Because Xeomin has none of those proteins, it carries a lower theoretical risk of antibody-mediated resistance. For most people getting occasional cosmetic treatment this never becomes an issue, but if your usual Botox has seemed to work less well over time, switching to Xeomin is a common and reasonable next step.
Because Xeomin doses 1:1 with Botox, its lower per-unit price flows straight through to your total. It typically runs 15–25% less — about $8–$12 per unit versus Botox’s $10–$15, so a standard frown-line treatment costs meaningfully less. As always, the saving is real but modest, and it’s not worth leaving an injector you trust to chase it. Compare the full neuromodulator math in the Botox cost guide, and weigh provider quality the same way you’d treat any bargain-priced injectable.
These are essentially the same. Both last about 3–4 months (some patients see five to six), and both begin working in roughly 3–5 days with peak effect at one to two weeks. Reports differ on whether one is marginally faster, but the difference isn’t clinically meaningful. If you specifically want longer duration, that’s a different product — Daxxify lasts about twice as long (see Botox vs Daxxify).
Botox has 30+ years of use and far more FDA approvals — frown lines, forehead lines, crow’s feet, neck bands, plus medical uses like chronic migraine and excessive sweating. Xeomin is approved for frown lines cosmetically (and several medical conditions) but has a narrower aesthetic label and a shorter history. For a routine cosmetic frown-line treatment this rarely changes the result, but if you want the deepest evidence base or a specific on-label area, Botox has the advantage.
A small but real practical difference: Xeomin doesn’t require refrigeration before use, while Botox does. This matters more to clinics than patients, but it can make Xeomin easier to stock and transport. It doesn’t affect your result either way.
As the same drug class, their side-effect profiles are very similar — mostly mild and temporary: headache, injection-site reactions, and occasional eyelid droop if the toxin spreads beyond the target. Both carry the same FDA class warning about toxin spread. The risk profile mirrors Botox’s side effects and differs from filler side effects, which center on the product’s physical presence. As always, the injector’s skill is the biggest safety variable.
Yes, easily — because the dosing is 1:1, your injector keeps essentially the same unit plan. Many people switch specifically for the purer formula or to address suspected resistance. Neither is reversible, so there’s no undoing a result — it simply fades, and you can switch back next time if you prefer.
Match the toxin to your priorities:
Lean Xeomin if: you want the purest formula, you’ve developed or worry about resistance, or you’d like to save 15–25%.
Lean Botox if: you want the longest track record, you also have a therapeutic need (migraine, sweating), or you want a specific on-label aesthetic area.
Both are excellent in skilled hands. Read more on the Botox and Xeomin hubs, then find and compare qualified injectors near you.
Remember these only treat movement lines. For lost volume — flat cheeks, thin lips, or under-eye hollows — you want fillers: lip filler for lips, or a brand like Juvederm or Restylane (compared in Juvederm vs Restylane) for cheeks, each with its own longevity and cost. And these two aren’t the only toxins: Dysport diffuses more and starts fast (see Botox vs Dysport), while Jeuveau is the cheap, aesthetics-only Botox analog (see Botox vs Jeuveau).
