If you have been researching injectable wrinkle treatments, you have likely encountered three names: Botox, Dysport, and Xeomin. All three are FDA-approved neurotoxins derived from botulinum toxin type A, and all three work by temporarily relaxing the muscles that cause dynamic wrinkles. But they are not identical products. At Blue Monarch Skin Studio in San Mateo, we take the time to explain the differences so you can feel confident in your treatment choice.
What They All Have in Common
Botox (onabotulinumtoxinA), Dysport (abobotulinumtoxinA), and Xeomin (incobotulinumtoxinA) all contain the same active ingredient: botulinum toxin type A. All three are injected into targeted muscles to temporarily reduce movement and soften the appearance of dynamic wrinkles. All three require a trained injector, have similar safety profiles, and produce results lasting approximately three to four months. The differences lie in their formulations, onset times, diffusion patterns, and pricing structures.
Botox: The Gold Standard
Botox, manufactured by Allergan (now AbbVie), has been FDA-approved for cosmetic use since 2002 and has the longest clinical track record of the three. The formulation contains the active toxin complexed with accessory proteins. Botox is known for its consistent, predictable results and is the most extensively studied neurotoxin in aesthetic medicine.
Onset: Most clients see results in 3 to 7 days, with full effect at 2 weeks.
Duration: Typically 3 to 4 months for most clients.
Spread: Botox has a moderate diffusion pattern and is generally considered very precise when placed by a skilled injector.
Best for: All standard cosmetic areas; ideal for clients who want a tried-and-true option with the largest body of long-term research behind it.
Dysport: Faster Onset, Wider Spread
Dysport, manufactured by Galderma, received FDA approval in 2009. It contains a slightly different protein complex and is typically diluted at a higher ratio than Botox, meaning the unit dosing is different — roughly 2.5 to 3 Dysport units equal 1 Botox unit. Dysport has a reputation for spreading slightly more, which can be a benefit or consideration depending on the treatment area.
Onset: Many clients notice results within 1 to 3 days, making it slightly faster-acting than Botox.
Duration: Similar to Botox, approximately 3 to 4 months, though some clients report it lasting slightly longer.
Spread: Dysport has a slightly wider diffusion radius, which can be advantageous for larger treatment areas like the forehead but requires care near smaller, more precise zones.
Best for: Large treatment areas where broader spread is beneficial; clients who want a faster onset; those with moderate to severe forehead lines.
Xeomin: The Naked Toxin
Xeomin, manufactured by Merz, received FDA approval in 2011 and is often called the naked toxin because it is a highly purified form of botulinum toxin type A without accessory proteins. This distinction matters for some clients: the absence of complexing proteins means there is theoretically a lower risk of developing antibody resistance over time, which can occur in a small percentage of long-term Botox or Dysport users.
Onset: Typically 3 to 5 days, similar to Botox.
Duration: Approximately 3 to 4 months.
Spread: Xeomin tends to stay precisely where it is placed, making it particularly suitable for small, targeted areas.
Best for: Clients who have developed resistance to other neurotoxins; those seeking precise, targeted treatment; those who prefer a formulation with no accessory proteins.
How Do We Choose at Blue Monarch?
At Blue Monarch Skin Studio in San Mateo, your provider will recommend a neurotoxin based on your unique anatomy, treatment goals, and history with injectables. In many practices, one product is stocked as the primary option, but understanding the alternatives helps you have an informed conversation with your injector. If you have used one product and feel the results were not optimal, switching formulations is always an option worth discussing.
Pricing and Value
Because of the unit ratio differences between products, pricing can look confusing at first. Dysport requires more units to achieve the same result as Botox, so the cost-per-unit appears lower but the total treatment cost is often comparable. Xeomin is typically priced similarly to Botox per unit. Always ask for a total treatment cost estimate rather than comparing per-unit prices across different products to get an accurate comparison for your San Mateo treatment.

Frequently Asked Questions
Is Botox better than Dysport?
Neither product is objectively better than the other. Both are FDA-approved, effective neurotoxins with similar safety profiles. The best choice depends on your treatment goals, anatomy, and personal history with injectables. Dysport may be preferred for its faster onset and broader coverage in large areas, while Botox offers a longer track record and consistent predictability. At Blue Monarch Skin Studio in San Mateo, your provider will recommend the right formulation based on your individual needs and goals.
What is a naked neurotoxin?
Xeomin is often called a naked neurotoxin because it contains botulinum toxin type A without the accessory proteins found in Botox and Dysport. These complexing proteins are believed to play no role in the cosmetic effect but may, in rare cases, trigger antibody formation over years of treatment. By removing them, Xeomin theoretically reduces the risk of resistance. For most clients, this distinction does not affect their experience, but it can matter for long-term users who have noticed diminishing results over time.
Can I switch between neurotoxins?
Yes. Switching between Botox, Dysport, and Xeomin is safe and common. Clients who feel one product is not lasting long enough or is not producing the desired result may benefit from trying an alternative formulation. It is important to let your provider know your complete history with neurotoxins so they can make the most informed recommendation. At Blue Monarch in San Mateo, we take a thorough history before any injectable treatment to ensure the best possible outcome for each client.
Does Dysport kick in faster than Botox?
Generally, yes. Many clients and providers report that Dysport has a slightly faster onset, with some clients noticing muscle relaxation within one to three days versus the three to seven days typical for Botox. However, this varies by individual and is not universally experienced. If you have an upcoming event and need faster results, Dysport may be a reasonable choice to discuss with your provider at Blue Monarch Skin Studio in San Mateo.
Are the results of Botox, Dysport, and Xeomin the same?
In terms of overall outcome, all three produce relaxation of targeted muscles and smoothing of dynamic wrinkles. The aesthetic results are broadly similar when dosed and placed correctly. Subtle differences in onset, spread, and duration mean one may suit your lifestyle or anatomy slightly better than another, but none will produce a dramatically different look. All three, in skilled hands, deliver the natural-looking relaxation that is the hallmark of excellent injectable work.
Is one neurotoxin safer than the others?
All three neurotoxins have FDA approval and well-established safety records for cosmetic use. When administered by a trained, experienced injector, the risk profile of all three is very similar. The accessory protein difference in Xeomin is sometimes cited as a safety advantage, but adverse events from any of the three are extremely rare when products are stored, handled, and injected properly. The most important safety factor is the skill and training of your injector, not the specific brand chosen.
How do I know which neurotoxin my provider uses?
Simply ask. Any reputable provider will be transparent about which product they use and why. At Blue Monarch Skin Studio in San Mateo, we are happy to discuss our product selection and the reasoning behind it during your consultation. If you have a preference or prior experience with a specific brand, let us know and we will factor that into your treatment recommendation. Informed clients tend to be happier clients, so we always encourage questions about the products we use.
Can I develop resistance to neurotoxins?
True resistance — where the neurotoxin stops working entirely — is rare but does occur in a small percentage of long-term users. It is caused by the development of neutralizing antibodies against the toxin protein. Risk factors include high doses, frequent treatments at very short intervals, and booster injections. Maintaining appropriate treatment intervals, using the minimum effective dose, and considering a switch to Xeomin if early resistance is suspected are all strategies to manage this possibility. Your Blue Monarch provider will help monitor your response over time.
