Xeomin
The only "naked" neurotoxin (incobotulinumtoxinA) by Merz Aesthetics -- purified to remove all accessory proteins for a cleaner formulation with reduced risk of antibody resistance.
What Is Xeomin?
Xeomin (incobotulinumtoxinA) is the only "naked" neurotoxin available -- an FDA-approved injectable by Merz Aesthetics that has been purified to remove all complexing proteins, leaving only the active botulinum toxin molecule. This purity reduces the risk of developing antibody resistance over time, making it an excellent option for long-term neuromodulator patients. Xeomin uses a 1:1 dosing ratio with Botox, produces equally effective results lasting 3-4 months, and does not require refrigeration before reconstitution.
What Is Xeomin?
Xeomin (incobotulinumtoxinA) is an FDA-approved prescription neurotoxin manufactured by Merz Aesthetics for the temporary improvement of moderate to severe frown lines between the eyebrows (glabellar lines) in adults. Like Botox and Dysport, Xeomin uses botulinum toxin type A to temporarily relax the muscles that cause dynamic wrinkles.
What makes Xeomin fundamentally different is its purity. Through a proprietary manufacturing process, Merz removes all complexing proteins (also called accessory proteins) from the botulinum toxin molecule. This produces what is often called a "naked" neurotoxin -- the purest form of botulinum toxin type A available. While Botox and Dysport contain these additional bacterial proteins clustered around the active molecule, Xeomin delivers only the therapeutic component.
Xeomin received FDA approval for cosmetic use in 2011 and has been used in over 50 countries worldwide. It is also FDA-approved for therapeutic uses including cervical dystonia, blepharospasm, and upper limb spasticity, demonstrating its broad safety profile across different applications and dosages.
The "Naked" Neurotoxin Advantage
The removal of complexing proteins is not just a marketing distinction -- it has meaningful clinical implications. Here is why this matters for patients:
Reduced Antibody Risk
When any protein is injected into your body, your immune system may produce antibodies against it. With traditional neurotoxins, your body can develop antibodies against both the active toxin and the accessory proteins. Over time, these antibodies can neutralize the toxin before it reaches the muscle, causing the treatment to become less effective -- a condition called secondary non-response. By removing accessory proteins, Xeomin reduces the total foreign protein load, potentially decreasing the risk of this antibody formation.
No Refrigeration Required
Unlike Botox, which must be refrigerated, Xeomin is stable at room temperature before reconstitution. This is a practical advantage that eliminates concerns about cold chain storage and ensures the product maintains its potency regardless of how it was shipped or stored before reaching your provider's office.
Same 1:1 Potency as Botox
Despite having fewer proteins, Xeomin is equally potent to Botox on a unit-for-unit basis. If you typically receive 20 units of Botox, you would receive 20 units of Xeomin for the same area. This 1:1 conversion makes it easy for both providers and patients to switch between the two products.
FDA-Approved Indications
Xeomin has received FDA approval for multiple conditions, demonstrating its safety across a wide range of uses:
- Glabellar lines (cosmetic): Temporary improvement of moderate to severe frown lines between the eyebrows in adults.
- Cervical dystonia: Treatment of abnormal neck pain and head position in adults.
- Blepharospasm: Treatment of abnormal spasm of the eyelids in adults previously treated with onabotulinumtoxinA.
- Upper limb spasticity: Treatment of increased muscle stiffness in the elbow, wrist, and fingers in adults.
- Chronic sialorrhea: Treatment of chronic drooling in adults.
Cosmetic Treatment Areas
For cosmetic purposes, Xeomin is used in the same areas as other neurotoxins:
Xeomin vs. Botox vs. Dysport
| Feature | Xeomin | Botox | Dysport |
|---|---|---|---|
| Generic Name | IncobotulinumtoxinA | OnabotulinumtoxinA | AbobotulinumtoxinA |
| Manufacturer | Merz Aesthetics | Allergan | Galderma |
| Accessory Proteins | None (purified) | Present | Present |
| Unit Conversion (vs Botox) | 1:1 | 1:1 | ~2.5-3:1 |
| Onset | 3-5 days | 3-5 days | 2-3 days |
| Duration | 3-4 months | 3-4 months | 3-4 months |
| Refrigeration | Not required | Required | Required |
| Antibody Risk | Lower (no extra proteins) | Standard | Standard |
Who Is Xeomin Ideal For?
While Xeomin is an excellent option for any patient seeking neurotoxin treatment, it is particularly well-suited for:
- Patients who have developed resistance: If your Botox or Dysport treatments seem to be wearing off faster or becoming less effective, switching to Xeomin may help restore responsiveness by reducing your body's antibody burden.
- Long-term neurotoxin users: Patients who plan to use neurotoxins for years may benefit from Xeomin's lower immunogenicity to maintain consistent results over the long term.
- Patients who prefer purity: Those who want the cleanest possible formulation with only the essential active ingredient.
- First-time neurotoxin patients: Starting with Xeomin minimizes early exposure to non-essential proteins, potentially preserving long-term treatment effectiveness from the beginning.

What to Expect During Treatment
A Xeomin treatment is a quick, convenient procedure that fits easily into a busy schedule:
The Procedure
Treatment takes approximately 10-20 minutes. Your provider will inject small amounts of Xeomin into the targeted muscles using a very fine needle. Most patients describe the sensation as a brief, mild pinch. No anesthesia is typically required, though ice may be applied before injection for comfort.
Recovery and Results
There is no downtime. You can return to normal activities immediately. Avoid rubbing the treated area for 4 hours and strenuous exercise for 24 hours. Results begin appearing within 3-5 days, with full effects visible at 14 days. The smoothing effects last 3-4 months, sometimes longer.
Frequently Asked Questions About Xeomin
What makes Xeomin different from Botox and Dysport?
Xeomin is the only "naked" neurotoxin, meaning it contains only the active botulinum toxin molecule without any complexing (accessory) proteins. Botox and Dysport both contain these additional proteins. This purification means there is less foreign protein for your immune system to react to, potentially reducing the risk of developing antibodies that could make the treatment less effective over time.
How long does Xeomin last?
Xeomin results typically last 3-4 months, comparable to Botox and Dysport. Some patients report results lasting up to 6 months. The duration depends on factors including treatment area, dosage, your metabolism, and the strength of the treated muscles. Regular maintenance treatments every 3-4 months are recommended to maintain smooth, consistent results.
Is Xeomin as effective as Botox?
Yes. Clinical studies have demonstrated that Xeomin is equally effective to Botox for the treatment of glabellar lines. Both use botulinum toxin type A and produce comparable results at the same dosing. The unit dosing is 1:1 with Botox, meaning 20 units of Xeomin produces the same effect as 20 units of Botox. The primary difference is Xeomin's purity and lower immunogenic potential, not its potency.
Who is Xeomin best suited for?
Xeomin is an excellent choice for all neurotoxin patients, but it is particularly well-suited for patients who have used Botox or Dysport extensively and may have developed diminishing results (secondary non-response), patients concerned about developing antibody resistance over years of use, those who prefer the purest possible formulation, and first-time patients who want to minimize exposure to non-essential proteins from the start.
Does Xeomin need to be refrigerated?
No. Unlike Botox, Xeomin does not require refrigeration before it is opened and reconstituted. This is a practical advantage that ensures consistent product quality regardless of storage and transport conditions. Once reconstituted with saline for injection, Xeomin should be used within 24 hours and stored in a refrigerator during that time.
How much does Xeomin cost?
Xeomin is typically priced similarly to or slightly less than Botox, ranging from $10 to $15 per unit. Because the dosing is 1:1 with Botox, the total treatment cost is straightforward to compare. Total costs range from $200 to $600 depending on the area treated and your geographic location. Merz offers the Xperience+ rewards program, which provides savings on Xeomin and Radiesse treatments.
