Botox vs Dysport vs Daxxify: Which Neurotoxin

Medically reviewed by Dr. Lena Ashford-Heller, MD, board-certified dermatologist — May 2026.

The neurotoxin market changed twice in the last 24 months. Daxxify's longer-lasting peptide formulation captured a meaningful share of the maintenance-injection market, and the shift from Allergan's near-monopoly on dynamic-line treatment to a four-product market (Botox, Dysport, Xeomin, Daxxify, plus newcomer Letybo from 2024) has finally normalized pricing. Across Zoca's MedSpa Directory network of 1,400+ medical aesthetic providers across 90 US cities, Botox still leads volume, but Daxxify has become the go-to for clients who hate touch-ups. Here's the 2026 comparison built on FDA labeling, peer-reviewed pivotal trials, and clinical experience reviewed by a board-certified dermatologist.

Quick Answer: Which neurotoxin is right for me in 2026?

Botox (onabotulinumtoxinA) is the gold standard at $13-$16 per unit and lasts 3 to 4 months — best for first-time patients and clinicians who want maximum predictability. Dysport (abobotulinumtoxinA) costs roughly $7 per unit (note: 2.5 to 3 Dysport units = 1 Botox unit), kicks in faster (day 2 to 3 vs Botox's day 4 to 7), and lasts 3 to 4 months — best for clients who want quick onset. Daxxify (daxibotulinumtoxinA) costs $10 per unit and lasts 6 to 9 months — best for maintenance patients who hate touch-ups.

The 2026 neurotoxin landscape — side by side

Note on units: Dysport is dosed differently than Botox. The Dysport-to-Botox conversion is approximately 2.5 to 3 Dysport units per Botox unit, so a 20-unit Botox glabellar treatment is roughly 50 to 60 units of Dysport at the same clinical effect. Compare total treatment costs, not per-unit costs alone.

What each neurotoxin actually does

All five products are botulinum toxin type an and work by blocking acetylcholine release at neuromuscular junctions, temporarily relaxing the targeted muscle. The differences come from accessory proteins, formulation, and shelf life — none of which the patient feels directly. The clinically meaningful differentiators are onset speed, duration, dose precision, and immunogenicity (chance of antibody formation).

The 2022 ASPIRE pivotal trial for Daxxify reported 50% of patients still had ≥1-point reduction in glabellar line severity at 6 months — the data that earned its longer-duration FDA labeling.

Pricing — what you'll actually pay in 2026

Glabellar lines (between the brows): typically 20 Botox units, 50 Dysport units, 18 Xeomin units, 20 Daxxify units. Cost: $260 to $320 (Botox), $300 to $400 (Dysport), $220 to $280 (Xeomin), $200 to $240 (Daxxify).

Forehead lines: 10 to 20 units (varies by anatomy). Cost: $130 to $320 (Botox), $150 to $400 (Dysport), $110 to $280 (Xeomin), $100 to $240 (Daxxify).

Crow's feet: 12 to 24 units bilateral. Cost: $156 to $384 (Botox), $180 to $480 (Dysport), $132 to $336 (Xeomin), $120 to $288 (Daxxify).

Full upper-face: 50 to 64 units typical. Cost: $650 to $1,024 (Botox), $750 to $1,280 (Dysport), $550 to $896 (Xeomin), $500 to $768 (Daxxify).

Annual cost comparison: Daxxify's longer duration means 1 to 2 sessions per year vs 3 to 4 for the others. For a full upper-face protocol, annual Daxxify cost is roughly equal to or slightly less than annual Botox/Dysport/Xeomin despite the higher per-session cost.

Risks, side effects, and what to avoid

All botulinum toxin type A products share an FDA Boxed Warning for distant spread of toxin effect. The American Academy of Dermatology lists common side effects: bruising at injection site (40 to 60% of patients per AAD reports), mild headache (10 to 15%), eyelid drooping (1 to 5%), eyebrow heaviness (5 to 10%), and rare allergic reaction. Most side effects resolve within 2 to 14 days. Eyelid drooping (ptosis) typically resolves over 2 to 8 weeks as the toxin wears off in the affected area.

The American Society of Plastic Surgeons recommends avoiding aspirin, ibuprofen, fish oil, vitamin E, and red wine for 7 days before injection to reduce bruising risk. Avoid laying down for 4 hours post-injection, avoid massaging the area for 24 hours, and skip heavy exercise for 24 hours.

Do not get neurotoxin injections during pregnancy or breastfeeding, with active infection at the injection site, with history of allergic reaction to botulinum toxin, with neuromuscular disorders (myasthenia gravis, Lambert-Eaton, ALS), or within 2 weeks of major facial surgery.

Onset and duration — the real-world experience

Dysport users typically see initial movement reduction at day 2 to 3 and full effect at day 7 to 14. Botox, Xeomin, and Letybo users see initial reduction at day 4 to 7 and full effect at day 10 to 14. Daxxify users see initial reduction at day 2 to 7 and full effect at day 7 to 14.

Duration is where the products diverge most. Botox, Dysport, Xeomin, and Letybo all run 3 to 4 months on average for upper-face treatment. Daxxify averages 6 months across all patients in pivotal trials, with about 50% of patients holding clinically meaningful effect at 6 months and a meaningful subset still showing effect at 9 months. Heavy exercisers, very physical jobs, and patients with high muscle activity in the treated area break down all toxins faster — some heavy CrossFit clients report Botox lasting only 8 to 10 weeks.

How to vet your provider — non-negotiable

For any neurotoxin injection in 2026, verify three credentials: (1) the injector is a board-certified dermatologist (ABMS-recognized), board-certified plastic surgeon, or a Registered Nurse / Nurse Practitioner / Physician Assistant working under physician supervision in compliance with your state's medical-spa scope-of-practice regulations; (2) the medspa carries malpractice insurance — ask to see the certificate; (3) the medspa stocks neurotoxin from a US-licensed distributor (Allergan, Galderma, Merz, Revance, Hugel) — counterfeit toxin from gray-market sources is a 2024-2025 problem the FDA actively warned about.

Avoid medspas that don't disclose the injector's credentials, practices that price aggressively below market, and any provider unwilling to do a 5 to 10 minute consultation before injection. The American Academy of Dermatology and American Society of Plastic Surgeons both maintain Find-a-Provider locators with credential verification.

What to ask at the consultation

Four questions: which neurotoxin do you recommend for my anatomy and goals, and why? What is your dose protocol for my specific treatment area, and how does that compare to the manufacturer's recommended range? What is your touch-up policy at 2 to 4 weeks if results are uneven? What is your management plan if I develop ptosis or unexpected weakness?

Final word

Botox remains the volume leader for good reason — 24 years of post-market data, predictable results, and broad clinician familiarity. Dysport offers faster onset and slightly better cost-per-treatment for some protocols. Daxxify's longer duration is the legitimate game-changer for maintenance patients. The right choice in 2026 depends on your anatomy, your tolerance for touch-ups, and your provider's clinical experience with each product. Use MedSpa Directory to filter for board-certified dermatologists, plastic surgeons, and physician-supervised injection practices in your city — and verify credentials at the AAD or ASPS provider locators before you book.
