Dysport vs. Botox vs. Daxxify: Which Lasts Longest?

When it comes to smoothing dynamic wrinkles and maintaining a naturally refined appearance, the neurotoxin you choose matters. Four names come up in almost every consultation in Miami: Dysport, Botox, Daxxify, and Xeomin. Each is botulinum toxin type A, and each carries a distinct profile, timeline, and personality. The question we hear most often is simple: which one lasts the longest?

The answer is more nuanced than a single product name. While Daxxify has earned attention for promising extended results, the best choice depends on your metabolism, aesthetic goals, and lifestyle. Let’s examine how all four compare—honestly, side by side—so you can walk into your consultation knowing what you’re choosing between.

One note on transparency before we start. At SkinUp Aesthetics & Wellness we carry Botox, Dysport, and Daxxify. We do not stock Xeomin. We’ve included it in this comparison anyway because patients ask about it constantly, and a comparison that quietly omits the product you’re curious about isn’t much of a comparison. Where Xeomin is genuinely the better fit for someone, we’d rather say so than pretend the option doesn’t exist.

Understanding Neurotoxins: A Quick Primer

All botulinum toxin type A products work by the same fundamental mechanism: they relax the muscles that create expression lines. What differs is the formulation, stabilizer, onset time, and longevity. Think of each neuromodulator as a precision tool with slightly different specifications—all effective, but suited to different scenarios.

If you’d like the wider view first—including Jeuveau and the functional uses of these products—our complete guide to neurotoxins in Miami covers all five side by side. This article goes deeper on the question that actually decides most consultations: duration.

At SkinUp in Miami, we believe in personalization. We don’t prescribe one product to every patient. Instead, we assess your individual factors and recommend the option that aligns with your timeline, budget, and aesthetic vision.

Daxxify: The Longest-Lasting Contender

Daxxify (daxibotulinumtoxinA-lanm) received FDA approval in September 2022 and represents a meaningful innovation in neuromodulator science. Manufactured by Revance Therapeutics, Daxxify is the first botulinum toxin stabilized with a proprietary peptide rather than human serum albumin or animal-derived components.

Duration: The clinical hallmark of Daxxify is longevity. Studies show a median duration of 6 months, with some patients maintaining results for up to 9 months. This means fewer injections per year—typically just two treatments, compared to three or four with traditional neurotoxins.

Why It Lasts Longer: Daxxify’s peptide stabilizer—a custom-engineered, 35-amino-acid peptide—appears to help the botulinum toxin bind more effectively at the nerve terminal. This formulation allows the active ingredient to work longer before the body naturally metabolizes it. It’s elegant biochemistry with visible results.

Additional Benefits: Beyond duration, Daxxify offers other advantages:

• Clean formulation: No human or animal byproducts, making it appealing to those prioritizing vegan-friendly treatments
• Faster onset: Some patients notice smoothing as early as 1–2 days, compared to 5–14 days for Botox
• Skin quality support: The active peptide may stimulate fibroblast activity, supporting collagen production and a subtle glow

The Caveat: While impressive, Daxxify’s extended duration isn’t universal. Individual results vary based on metabolism, muscle mass, and biological factors. What lasts 9 months for one patient might last 6 months for another—and that’s still excellent.

Botox: The Gold Standard

Botox (onabotulinumtoxinA) remains the most recognized neuromodulator globally, with decades of clinical data and refinement. Its stability in the market isn’t accident—it’s earned through consistent, predictable results.

Duration: Botox typically lasts 3–4 months. For most patients in Miami, this means four treatments per year to maintain a consistent appearance.

Why Botox Endures: Despite newer options, Botox maintains its position because it’s reliable. It has the widest body of safety data, physicians know it intimately, and results are highly predictable. Many aesthetic professionals and patients simply prefer what they know.

Cost Profile: Botox generally ranges from $10–16 per unit, with most patients requiring around 20 units for glabellar lines. Total cost per treatment is often lower than Daxxify, but annual expenses approach parity when factoring in frequency.

Who Chooses Botox: Patients who prefer regular appointments, those exploring neurotoxins for the first time, or anyone comfortable with the classic 3–4 month timeline.

Dysport: The Faster-Spreading Option

Dysport (abobotulinumtoxinA) is another solid option, prized for its diffusion profile and rapid onset.

Duration: Like Botox, Dysport typically lasts 3–4 months, requiring similar treatment frequency.

Unique Profile: Dysport spreads more broadly across the injection area, making it excellent for patients who prefer a softer, more diffused result. It also tends to show results slightly faster than Botox—often within 3–5 days.

Units and Pricing: Dysport typically costs less per unit ($8–12), but because it spreads more, patients often need more units overall. When you do the math, annual costs align closely with Botox and sometimes approach Daxxify pricing.

Who Chooses Dysport: Those seeking a gentler, less targeted appearance, or patients with a history of great results with diffusing neuromodulators.

Xeomin: The Stripped-Down Formulation

Xeomin (incobotulinumtoxinA) is manufactured by Merz Aesthetics and was FDA-approved in 2010 for therapeutic use, with cosmetic approval for frown lines following in 2011. It occupies a specific niche in the category.

Duration: Xeomin typically lasts 3–4 months, placing it alongside Botox and Dysport rather than in Daxxify’s extended tier.

What Makes It Distinctive: Xeomin is manufactured without complexing proteins—the bacterial accessory proteins that surround the active molecule in Botox and Dysport. It’s often called the “naked” toxin for that reason, though the nickname oversells it: complexing-protein-free is not the same as excipient-free, and Xeomin still contains human albumin and sucrose as stabilizers, so it is not a vegan or animal-free option the way Daxxify is. What it strips out is the bacterial accessory protein load, and in theory fewer foreign proteins mean less for the immune system to respond to. That matters to a small group of long-term patients who develop neutralizing antibodies and stop responding well to their usual product.

Onset and Potency: Results generally begin at 3–5 days, with full effect by week two. You’ll often see Xeomin and Botox described as dosing “one to one,” and in practice the numbers frequently land close. Take that as background, not as math you can do yourself: FDA labeling for every botulinum toxin is explicit that potency units are specific to each product and cannot be converted between brands. Your unit count comes from your injector reading your anatomy, not from arithmetic on your last treatment.

The Honest Caveat: True antibody resistance is uncommon. For the large majority of patients, the practical difference between Xeomin and Botox in the mirror is negligible—same onset window, same duration, same result. The stripped-down formulation is a real advantage for a specific patient, not a general upgrade.

Who Chooses Xeomin: Patients who’ve been treated for many years and suspect diminishing response, and those who prefer a formulation carrying fewer accessory proteins.

Where SkinUp Stands: We don’t carry Xeomin. Our reasoning is the same reasoning behind every part of our menu: we’d rather stock three neurotoxins we know intimately—their dilution behavior, their diffusion patterns, how each settles in a given muscle at week two—than five we reach for occasionally. Botox already covers the predictability and the extensive safety record; Dysport covers the faster, softer, more diffused result; Daxxify covers duration.

Worth knowing if the purified formulation is what drew you to Xeomin: it isn’t the only complexing-protein-free option. Daxxify is built on the same 150-kDa core neurotoxin, stabilized with a synthetic peptide instead of the traditional route, so it meets that same structural criterion—and we do carry it. Our Xeomin in Miami guide works through that comparison properly, along with what’s usually happening when a neurotoxin stops working.

Which Neurotoxin Lasts the Longest?

The short answer: Daxxify. It’s the only product in this comparison formulated for extended duration, and it’s the only one that consistently reports beyond the four-month mark.

Ranked by typical duration:

1. Daxxify — 6 months median, up to 9 months for some patients. The peptide stabilizer is the reason, and the gap over the rest of the category is real, not marketing.
2. Botox — 3–4 months. The benchmark the entire category is measured against.
3. Xeomin — 3–4 months. Effectively equivalent to Botox in longevity.
4. Dysport — 3–4 months. Comparable duration, with a faster onset at the front end.

That ranking is stable. What isn’t stable is how it plays out on your face, and this is where the honest answer gets more useful than the ranked list.

What actually changes your duration:

• Metabolism. Faster metabolisms clear botulinum toxin faster. It’s the single largest variable, and it’s not something you control.
• Muscle strength. Strong, frequently-used muscles—a deep glabellar frown, a heavy forehead—overcome a given dose sooner than delicate ones.
• Dose. Underdosing is the most common reason results fade at eight weeks. A dose matched to your anatomy lasts closer to the published range.
• Treatment history. Patients treated consistently for years often find results lasting longer over time, as the treated muscles gradually weaken with reduced use.
• Exercise and intensity of training. Very high-output athletes frequently report shorter duration, likely through the same metabolic mechanism.

The reframe we offer patients: longest-lasting and best-for-you are different questions. Daxxify wins the first one outright. But a patient who wants two appointments a year and a patient who wants to reassess their face every quarter are optimizing for genuinely different things, and neither is wrong. Duration is one input into the decision, not the decision itself.

Two notes on reading that table. Units are not comparable across brands—FDA labeling states potency units are specific to each product and cannot be converted, which is why the typical glabellar dose differs by product rather than scaling from a single number. And per-unit pricing above reflects the Miami market generally, not a SkinUp price list. For what a full treatment actually costs here, see our Botox pricing guide for Miami—unit counts matter far more than the per-unit number.

Individual Results Vary—And That’s Important

One truth stands above all others: neurotoxin response is deeply individual. Your metabolism, muscle mass, previous exposure to these products, and even your genetics influence how long results last and how quickly you see them.

We’ve seen Daxxify last longer than expected in some Miami patients and last closer to 6 months in others. We’ve seen Dysport patients maintain excellent results for closer to four months and others who return sooner. This variability isn’t a flaw—it’s biology.

At SkinUp, this is precisely why we listen carefully during your consultation. We ask about your past experiences, your timeline preferences, and your aesthetic goals. A patient who loves the ritual of a quarterly appointment might lean toward Dysport, while someone juggling a demanding schedule might prefer Daxxify’s efficiency.

The Case for Having Options

Here’s what we’ve learned in Miami: there’s no universally perfect neurotoxin. At SkinUp we offer Botox, Dysport, and Daxxify because, between them, they cover the full range of what most patients are looking for—the trusted predictability of Botox, the rapid onset and soft diffusion of Dysport, and the extended duration with a clean, peptide-stabilized formulation of Daxxify. Xeomin sits close enough to Botox in practice that adding it would broaden the shelf without broadening what we can actually do for you. This guide is meant to help you compare honestly so you and your provider can choose the right option for your goals.

Scenario 1: The Long-Term Planner You prefer minimal maintenance and would rather schedule two appointments yearly than four. Daxxify aligns with your lifestyle, and you’re willing to invest slightly more per unit for that convenience.

Scenario 2: The Ritual Enjoyer You love the quarterly rhythm of your aesthetic maintenance and want a familiar 3–4 month cycle. Dysport delivers that rhythm with the added benefit of faster onset, which is why it is the option we most often recommend for patients who previously enjoyed that classic quarterly cadence with another brand.

Scenario 3: The Soft-Results Seeker You want natural-looking softening rather than frozen immobility. Dysport’s diffusion profile delivers the gentle sophistication you’re after.

Scenario 4: The First-Timer You’re exploring neurotoxins for the first time and want a time-tested option with abundant safety data. Botox has been FDA-approved for cosmetic use since 2002 and remains the most extensively studied neuromodulator on the market, while Dysport (FDA-approved since 2009) offers a softer, faster-onset alternative with its own deep safety record. Either is a reassuring, well-studied starting point at SkinUp.

Scenario 5: The Long-Time Patient Whose Result Has Weakened You’ve been treating for years and your last few rounds haven’t held. Formulation is worth discussing here—Daxxify is complexing-protein-free, the characteristic patients usually have in mind when they ask about Xeomin—but the cause is more often dose, interval, or technique than the product itself. Our Xeomin in Miami guide walks through what’s actually going on when a neurotoxin stops working, and how we evaluate it.

Common Questions About These Neuromodulators

Q: Which neurotoxin lasts the longest? A: Daxxify, by a clear margin—roughly 6 months median against 3–4 months for Botox, Dysport, and Xeomin. Your metabolism, dose, and muscle strength shift that number more than the brand does.

Q: What’s the difference between Xeomin and Botox? A: Xeomin is botulinum toxin type A with the accessory proteins stripped out; Botox retains them. Onset and duration are similar, and for most patients the visible difference is negligible. Two things worth knowing: Xeomin still contains human albumin and sucrose, so it isn’t the vegan option, and potency units are product-specific under FDA labeling—they don’t convert between brands. Xeomin’s advantage is specific: it matters most to long-term patients concerned about antibody formation.

Q: Does SkinUp offer Xeomin? A: No—we carry Botox, Dysport, and Daxxify. Between the three, we cover the predictability, onset, diffusion, and duration profiles most patients need, and we’d rather know three products deeply than five occasionally. We include Xeomin in this comparison because you asked, not because we’re selling it.

Q: Is Daxxify better than Botox? A: “Better” depends on your priorities. Daxxify excels at extended duration and reduced appointment frequency. Botox excels at predictability and decades of clinical data. Better is personal.

Q: Do all neuromodulators work the same way? A: Yes, fundamentally. All relax muscles by blocking acetylcholine at the neuromuscular junction. What differs is formulation, onset time, diffusion, and longevity.

Q: Is Daxxify vegan? A: Yes—it’s the only neuromodulator on the market formulated without human or animal byproducts. Its peptide stabilizer is synthetically created, making it suitable for patients with vegan values.

Q: Can I switch between neuromodulators? A: Absolutely. Some patients rotate between options based on their schedule or mood. Others find one product and stay loyal. Both approaches are valid.

Q: Does the peptide in Daxxify really improve skin quality? A: The peptide appears to stimulate fibroblast activity, potentially supporting collagen and skin texture. While subtle, some patients report a perceived glow. It’s a nice bonus, though the primary benefit remains wrinkle relaxation.
