People use “Botox” the way people say “Kleenex”—as a catch-all for any wrinkle relaxer. But Botox, Dysport, and Xeomin are three distinct products, and the differences between them are real enough to affect your results. Bogat offers Botox and Dysport, along with the longer-lasting Daxxify, at its Hallandale Beach clinic; Xeomin is covered here for comparison. The Botox & Wrinkle Relaxers page covers areas, dosing, and what a visit looks like.

Quick Definitions
Neurotoxin / Neuromodulator / Wrinkle Relaxer = the category. All three products belong to it.
Botox = onabotulinumtoxinA, made by AbbVie/Allergan. FDA cosmetic approval: 2002. [1]
Dysport = abobotulinumtoxinA, made by Ipsen. FDA cosmetic approval: 2009. [2]
Xeomin = incobotulinumtoxinA, made by Merz. FDA cosmetic approval: 2011. The only one made without complexing (accessory) proteins. [3]
Mini takeaway
- Same active ingredient (botulinum toxin type A), different formulations
- “More units” doesn’t mean better — Dysport is dosed at roughly a 3:1 ratio to Botox and Xeomin
- The best neurotoxin is the one that fits your treatment area, muscle activity, and medical history
What They Have in Common
All three temporarily relax the specific muscles that create expression lines. They work by blocking the nerve signal that tells a muscle to contract — when the muscle can’t contract, the overlying skin stops creasing. [4]
The wrinkles they treat best are dynamic wrinkles — lines that appear with movement: crow’s feet from squinting, “11s” between the brows from frowning, horizontal forehead lines from raising your eyebrows. They’re not the right tool for static lines (the ones visible at rest) or volume loss, which is where dermal fillers come in.
All three are FDA-approved, require no downtime, and last roughly 3–4 months. The treatment itself is quick; the assessment that precedes it — reading your muscle movement, mapping injection points, dialing in the right product and dose for your face — is where the expertise lives. [4]

The Key Difference: What’s In the Vial
The active ingredient — botulinum toxin type A — is the same in all three. What differs is the rest of the formulation.
Botox
Botox contains the neurotoxin surrounded by complexing proteins, giving it a molecular weight of approximately 900 kDa. [5] Those proteins were originally thought to stabilize and protect the toxin, though their clinical significance in cosmetic dosing is still debated. What’s clear is that they influence how the product diffuses under the skin and how the immune system responds over time.
Dysport
Dysport also contains complexing proteins, but in a lighter configuration — a mixture of approximately 300 kDa and 500 kDa complexes. [5] This smaller molecular size is part of why Dysport spreads more readily once injected. Its inactive ingredients are human albumin and lactose. Dysport is contraindicated for anyone with a known allergy to cow’s-milk protein, so tell your injector about a dairy-protein allergy before treatment. [6]
Xeomin
Xeomin is the stripped-down version — botulinum toxin type A with no accessory proteins at all, giving it a molecular weight of approximately 150 kDa. [5] It’s often called the “naked” injectable for this reason. Its inactive ingredients are human albumin and sucrose — so “protein-free” isn’t accurate; the precise description is made without complexing (accessory) proteins. Unopened vials can be stored at room temperature. Because the complexing proteins are removed, Xeomin is often described as having the lowest immunogenic load, although neutralizing antibodies have been reported with every type-A product, including Xeomin. [3]
Why the Formulation Differences Matter
Spread and precision
The protein content directly affects how far each product migrates from the injection point.
Xeomin spreads the least — roughly dime-sized. Botox spreads slightly more — about penny-sized. Dysport spreads the most — approximately quarter-sized. [4]
This isn’t a flaw in any of them — it’s a design characteristic that makes each one more suited to certain areas. Dysport’s wider diffusion is an advantage when treating a large muscle like the forehead; it can cover more territory with fewer injections. Botox and Xeomin’s more contained spread is an advantage for precision work around the eyes, where you don’t want product drifting toward the levator muscle (which keeps the eyelid elevated). [5]
Onset
Most patients notice Dysport working first — visible results often appear within 2–3 days. Botox typically takes 3–7 days for visible change. Xeomin lands in the middle at around 4–5 days. [6] All three reach their full effect by 2 weeks, which is why providers schedule follow-up checks at that point rather than sooner.
Duration
All three average 3–4 months. Individual variation is significant — your metabolism, muscle strength, stress levels, and how much you exercise can all affect how quickly results fade. [4] Some patients consistently get 5 months from one product; others wear through any neurotoxin in 10 weeks. Tracking this over a few treatment cycles tells you more than any general guideline.
Antibody resistance
This is the factor most patients don’t hear about — and it matters most for long-term users.
Any botulinum toxin product can, over repeated treatments, prompt the immune system to make neutralizing antibodies — proteins that block the toxin before it works. When that happens, results become weaker or shorter. Two things are worth knowing. First, these antibodies target the core neurotoxin molecule, which is the same in Botox, Dysport, and Xeomin, so a patient who has become resistant to one product may not respond fully to another. [11] Second, at cosmetic doses this is rare: in the manufacturers’ own trials, no Botox Cosmetic or Dysport glabellar-line patient developed neutralizing antibodies, and Xeomin reported them in fewer than 1% of patients across all approved uses. [3][6][10] Higher rates have been reported in patients treated for years with large therapeutic doses for conditions like cervical dystonia, which is a different situation from cosmetic treatment. [8]
Xeomin is manufactured without complexing proteins, which is why it is often chosen by long-term users who prefer the simplest formulation. Neutralizing antibodies are uncommon at cosmetic doses, and before considering true non-response, Bogat’s providers first evaluate facial anatomy and muscle movement, injection placement, dose, treatment intervals, and patient-specific factors. Only then is a change of product considered, and product selection is always individualized. The most protective habits are the boring ones: the lowest effective dose, at the longest interval that still gives you the result you want. [10][11]
Dosing: Units Are Not the Same
One of the most confusing parts of comparing neurotoxins is that they’re measured in different units — and those units are not interchangeable.
The standard conversion is: 1 unit of Botox ≈ 1 unit of Xeomin ≈ 3 units of Dysport. [6]
This means if your provider tells you Dysport is cheaper per unit, they’re right — but you’ll need approximately three times as many units to treat the same area. The final treatment cost often ends up comparable.
Typical units by treatment area:
| Treatment Area | Botox | Dysport | Xeomin |
|---|---|---|---|
| Crow’s feet | 10–15 units | 30–45 units | 10–20 units |
| Forehead lines | 10–15 units | 30–45 units | 10–20 units |
| Glabellar / “11” lines | 20–30 units | 50–70 units | 20–30 units |
These are general ranges. Your actual units will depend on your muscle mass, the depth of the lines, and your provider’s technique. Never price-compare neurotoxins by per-unit cost alone — always look at the projected total units for your specific treatment.
Which One Is Right for You?
There’s no universally “best” neurotoxin. The right choice depends on your anatomy, the area being treated, your allergy history, and how your body has responded to previous treatments.
Botox makes the most sense if:
- You’re new to injectables and prefer the most extensively studied option
- You’re treating crow’s feet or other areas that require contained, precise placement
- You want a treatment with the broadest FDA-approved indications [1]
Dysport makes the most sense if:
- Your primary concern is the forehead or areas where broader coverage is an advantage
- You have strong, active muscles and need a product with good diffusion to soften larger areas [6]
- You want faster initial results — useful if you’re working around a specific event
- You don’t have a cow’s-milk-protein allergy (a Dysport contraindication)
Xeomin makes the most sense if:
- You prefer a formulation made without complexing proteins
- Your provider has reviewed your dose, placement, and spacing and recommends trying a different product
- You’re planning long-term neurotoxin use and want the simplest formulation
- You want the simplest formulation, made without complexing proteins [3]
Can you use more than one?
Yes. Some providers use different neurotoxins in different areas of the same treatment session — for example, Dysport for a large forehead and Botox around the eyes. It’s less common but not unusual.
Can you switch between them?
Yes, safely. Most providers recommend waiting until your current treatment has fully worn off before switching products. If results fade over time, switching products is one option your provider may discuss, after dose, placement, and spacing have been reviewed. [11]
What to Expect: Before, During, and After
Before your appointment
For about 7 days before treatment, whenever medically appropriate, pause over-the-counter blood thinners and supplements that increase bruising (aspirin, ibuprofen, fish oil, high-dose vitamin E) — unless they were prescribed; never stop a prescription medication without checking with your prescriber. Skip alcohol for 24 hours before. Arrive with a clean face — no makeup on the treatment area.
During treatment
Your provider will assess your muscle movement, mark the injection points, and use a very fine needle to inject small amounts into targeted muscles. The whole process usually takes 10–15 minutes. You’ll feel a small pinch at each injection site. Most people find it very manageable; if you’re concerned, ask your provider about a topical numbing option.
After treatment
- Avoid rubbing or massaging the treated area for 4 hours
- Skip strenuous exercise and extreme heat (saunas, hot yoga) for 24 hours
- Stay upright for the first few hours — no lying face-down
- Don’t panic if nothing is visible in the first 48 hours — onset takes time
- Return for a two-week follow-up so your provider can assess results and add units if needed [4]
Mistakes That Make Results Worse
Rubbing the treated area. The most common post-treatment mistake. Rubbing can cause the neurotoxin to migrate to unintended muscles.
Exercising too soon. Increased blood flow in the first 24 hours can disperse the product before it’s fully settled.
Skipping the two-week follow-up. This is where underdosed areas get corrected. Skipping it means accepting incomplete results.
Choosing a provider based on price alone. Neurotoxin placement is the primary driver of results — technique, anatomy knowledge, and product selection matter far more than which brand is in the vial.
Expecting static lines to disappear. Neurotoxins relax muscles. They don’t fill volume or remodel skin texture. Lines that are visible at rest — especially deep ones — may need a combination approach including fillers or resurfacing.
Waiting until results are completely gone before re-treating. Treating on a consistent schedule (every 3–4 months) before the muscle regains full strength tends to produce better long-term results than waiting until wrinkles fully return.

Glossary
Neurotoxin / Neuromodulator
An injectable protein that temporarily blocks nerve signals to muscles, reducing their ability to contract. Used in aesthetics to soften dynamic wrinkles.
Dynamic wrinkles
Lines that appear or deepen with facial movement — frowning, squinting, raising the eyebrows. Neurotoxins address these directly.
Static wrinkles
Lines visible at rest, regardless of muscle movement. Often require fillers or resurfacing rather than (or in addition to) neurotoxins.
Complexing proteins / Accessory proteins
Non-active proteins that surround the botulinum toxin molecule in Botox and Dysport. They affect how the product spreads. Xeomin is manufactured without them.
Neutralizing antibodies
Immune proteins the body produces in response to foreign proteins. When they form against a neurotoxin, they can reduce or eliminate treatment effectiveness.
Diffusion / Spread
How far a product migrates from the injection site. Higher diffusion (Dysport) covers more area; lower diffusion (Xeomin) allows more precision.
Unit
A measure of neurotoxin potency — but units are product-specific. One Botox unit ≠ one Dysport unit. The standard conversion is approximately 1 Botox unit = 3 Dysport units.
