All three are FDA-approved botulinum toxin type A products that smooth dynamic wrinkles. Botox leads in research depth and precision. Dysport diffuses further and kicks in 24–48 hours faster — ideal for the forehead. Xeomin has no accessory proteins, making it the top choice if Botox results have declined over time. At Solace, all three are available at pricing that delivers comparable total treatment costs.
What Are Neuromodulators?
Botox, Dysport, and Xeomin all belong to a class of cosmetic injectables called neuromodulators. Each is derived from botulinum toxin type A — a purified protein that temporarily interrupts the signal between nerves and muscles.
When a muscle contracts repeatedly over years — squinting, frowning, raising your brows — it etches permanent creases into the overlying skin. A neuromodulator doesn't fill those creases; it pauses the muscle movement that creates them. Within days of injection, the treated muscle relaxes. The skin above smooths out. With consistent treatment over time, the lines often soften further even between appointments.
All three products are reviewed and approved by the U.S. Food and Drug Administration for cosmetic use. They differ not in what they are — botulinum toxin type A — but in how they're formulated, how quickly they act, and how they spread in tissue.
How Botulinum Toxin Works
Each product delivers the same active ingredient: botulinum toxin type A. The toxin binds to nerve terminals at the neuromuscular junction and blocks the release of acetylcholine — the chemical messenger that signals a muscle to contract. With that signal blocked, the muscle relaxes and stops generating movement. The effect is temporary because nerve terminals regenerate over three to four months, gradually restoring signal transmission and muscle function.
The key difference between products lies in what surrounds the active toxin molecule. Botox and Dysport contain accessory (complexing) proteins that affect how the product behaves in tissue. Xeomin is formulated without these proteins — a distinction that matters for a specific subset of patients who have developed antibody responses over multiple treatment cycles.
The Real Differences
Botox — The Original Standard
Botox (onabotulinumtoxinA) received FDA cosmetic approval in 2002, making it the first and most-studied neuromodulator available. Its 20-plus year track record means more clinical data, more trained injectors, and more consistent predictability than any competing product.
Botox diffuses modestly from the injection site — an advantage for precise, small-area work. Crow's feet, lip lines, bunny lines, and brow lifting all benefit from Botox's controlled spread. Onset typically runs three to seven days, with full results visible by day fourteen. Duration averages three to four months; regular patients often extend results to four to five months as treated muscles gradually lose contraction memory.
Ideal candidate: First-time neuromodulator patients, anyone requiring precise results in small treatment zones, and patients with a solid Botox history who are not experiencing resistance.
Dysport — Faster Spread, Earlier Results
Dysport (abobotulinumtoxinA) received FDA cosmetic approval in 2009, specifically for glabellar lines — the vertical creases between the brows. Its formulation includes smaller protein molecules than Botox, allowing it to diffuse approximately 1–2 cm further from the injection site in tissue.
This wider spread is a clinical advantage for large treatment areas. The forehead spans several inches and requires coverage across multiple muscular planes; Dysport's diffusion pattern achieves more even distribution with fewer injection points. Onset is also meaningfully faster — most patients see softening within 24 to 72 hours, a full two to four days earlier than Botox.
Important: Dysport units are not equivalent to Botox units. The standard conversion is 2.5–3 Dysport units per 1 Botox unit. At Solace pricing ($5/unit Dysport vs. $13/unit Botox), total treatment costs are comparable once the conversion is applied.
Ideal candidate: Patients with significant horizontal forehead lines, high-activity foreheads, patients who want the fastest possible onset, and patients who have responded well to Botox and want to compare the alternative.
Xeomin — The Naked Neuromodulator
Xeomin (incobotulinumtoxinA) received FDA approval in 2011. Its defining characteristic: it contains only the pure botulinum toxin molecule with no accessory complexing proteins whatsoever. Merz Pharmaceuticals designed it specifically to eliminate the proteins that can trigger antibody formation in long-term neuromodulator patients.
Over time, a small percentage of patients who receive Botox or Dysport develop antibodies to the accessory proteins. These antibodies reduce efficacy — results come in shorter, less complete, or require increasingly higher doses. Because Xeomin has no accessory proteins, there is nothing for the immune system to form antibodies against. For patients experiencing genuine Botox resistance, Xeomin is the most evidence-supported alternative.
Onset and duration closely mirror Botox: three to seven days onset, three to four months duration. Dosing is approximately 1:1 with Botox units.
Ideal candidate: Patients with suspected or confirmed Botox resistance, patients seeking a protein-free formulation, and anyone who has noticed progressively shorter duration or weaker results from Botox over multiple treatment cycles.

Who Should Choose Each?
Choose Botox if you're a first-timer who wants the most-studied and predictable product. Botox's 20-plus year dataset, narrow diffusion pattern, and broad FDA clearance make it the logical starting point when there is no prior treatment history to reference. It's also the better choice for small, precise areas — crow's feet, lip lines, bunny lines — where tight placement control matters most.
Choose Dysport if your primary concern is the forehead and you want visible results as quickly as possible. Dysport's wider diffusion means fewer injection points for broad coverage, and its 24–48 hour onset is measurably faster. Patients who've been treated with Botox and want to compare often appreciate how quickly Dysport kicks in, along with the natural-looking relaxation it provides across a larger surface area.
Choose Xeomin if you've noticed your Botox results getting shorter or less complete over time and dose adjustments haven't helped. Declining duration across multiple treatment cycles — especially when other variables haven't changed — is the classic sign of antibody formation. Xeomin's protein-free formulation bypasses the antibody response entirely and is the most evidence-supported option for resistance cases.
Can You Use More Than One in the Same Visit?
Yes — combining neuromodulators in a single session is clinically valid and sometimes strategically advantageous. A common approach: Dysport on the forehead for broader coverage and faster onset, plus Botox on the crow's feet for precision. The products are tracked separately with independent dosing protocols for each zone, so your injector must be comfortable managing both unit systems simultaneously. At Solace, Dr. Flávio assesses during your consultation whether a combination approach fits your anatomy and goals.
Fort Myers Pricing & What to Expect at Solace
All three neuromodulators are available at Solace Wellness Aesthetics with transparent, per-unit pricing:
- Botox: $13/unit. A typical full-face treatment (forehead + glabellar lines + crow's feet) runs 30–50 units — approximately $390–$650.
- Dysport: $5/unit. The same treatment area in Dysport requires 75–150 units at the 3:1 ratio — approximately $375–$750, comparable to Botox in total cost.
- Xeomin: $13/unit. Dosing and total pricing equivalent to Botox.
Every neuromodulator appointment begins with a facial assessment and consultation with Dr. Flávio, who maps your muscle anatomy and recommends the right product, placement, and dose for your specific concerns. All appointments include a two-week follow-up — if results are uneven or incomplete, a complimentary touch-up is provided at no additional cost.
Our Recommendation
For most first-time patients at Solace, we start with Botox. The two-decade safety profile, extensive published literature, and predictable diffusion make it the right foundation when there's no prior treatment data to reference. First treatments are intentionally conservative — and Botox's tighter spread reduces the chance of unintended relaxation in adjacent muscle groups.
For patients with active, high-movement foreheads, Dysport is often the stronger clinical choice. The coverage is more even, the onset is faster, and many patients find the natural-looking forehead relaxation with Dysport superior to their Botox results in that specific area.
For patients who have genuinely lost response to Botox over time — shorter duration, weaker results, higher doses with diminishing returns — Xeomin is the evidence-supported next step. The peer-reviewed literature on its effectiveness in protein-antibody-mediated resistance cases is well-established.
Which product is right for you? That's exactly what the consultation is designed to answer. Book below and Dr. Flávio will walk through your history, anatomy, and goals before a single unit is placed.
Clinical reference: FDA approval data, American Society of Plastic Surgeons, and comparative neuromodulator literature confirm all three products carry comparable safety profiles when dosed by a trained provider.
American Society of Plastic Surgeons — Botulinum ToxinFrequently Asked Questions
Is Dysport actually cheaper than Botox?
Per unit, yes — Dysport at $5/unit is lower than Botox at $13/unit. But Dysport requires 2.5–3x more units per treatment area, making total treatment costs comparable. Treating a forehead with Botox might use 20 units ($260); the same area with Dysport typically requires 50–60 units ($250–$300). Always compare total treatment cost for the area, not just the per-unit price.
Which neuromodulator lasts the longest?
All three average three to four months, and no product has demonstrated consistently longer duration in head-to-head clinical trials. Duration depends more on dose, treatment frequency, and individual metabolism than on brand. Patients who maintain a consistent schedule — typically every three to four months — often see their results extend over time as the target muscles gradually relax and require less product to stay smooth.
If Botox stopped working, would Xeomin help?
Possibly — and for a specific subset of patients, yes. True Botox resistance is caused by antibodies to the accessory proteins surrounding the toxin molecule, not to the toxin itself. Because Xeomin contains no accessory proteins, it bypasses the antibody response entirely. If your results have genuinely declined over multiple treatment cycles — shorter duration, weaker relaxation, higher doses with diminishing returns — and other variables like technique and dosing have been ruled out, Xeomin is the most evidence-supported alternative. Dr. Flávio can assess whether resistance is the likely explanation during your consultation.
Can you use Botox and Dysport in the same visit?
Yes — combining products in a single session is safe and sometimes strategically advantageous. A common approach is Dysport on the forehead for wider coverage and faster onset, plus Botox on the crow's feet or perioral lines for precise placement. Each product is tracked with its own dosing system since the unit counts are not interchangeable. This combination strategy requires an injector comfortable managing both unit systems simultaneously, which Dr. Flávio can accommodate at Solace.
Which is the best choice for a first-time patient?
Botox is the standard recommendation for first-timers because of its 20-plus year clinical track record, the largest published safety dataset of any neuromodulator, and its predictable diffusion pattern. When there's no prior treatment history, Botox's narrower spread reduces the chance of unintended relaxation in adjacent muscles. First-time treatments at Solace are always conservative — you can add more at your two-week follow-up, but you can't take it away. Starting with the most-studied, most controllable product is simply the safest approach.
How do I know which neuromodulator is right for me?
The honest answer is that most patients do well on any of the three, and injector skill with dosing and placement matters more than brand selection. The meaningful decision points are: first-timer (Botox), large forehead with fastest-possible onset (Dysport), or declining results over multiple cycles (Xeomin). At Solace, Dr. Flávio reviews your treatment history and facial anatomy at consultation and makes a recommendation based on both. Book a consultation and you'll leave knowing exactly which product fits your situation.
