What Is Dysport? A Complete Guide

Dysport is one of the most popular wrinkle-relaxing injectables in the US and a close cousin of Botox: both are botulinum toxin type A. Its generic name is abobotulinumtoxinA. Known for a fast onset and a smooth, even spread, Dysport is especially popular for the forehead. This guide covers what Dysport is, how it works, what it treats, how long it lasts, what it costs, its safety, and how it stacks up against Botox.

What is Dysport?

Dysport is the brand name for abobotulinumtoxinA, a purified botulinum toxin type A — the same family of neuromodulators as Botox. It’s manufactured by Ipsen and distributed in aesthetics by Galderma (and sold as Azzalure in Europe). The defining feature of its formulation is a smaller protein complex, which lets it diffuse more broadly from each injection point — the trait behind most of its practical advantages and trade-offs.

Dysport has been used in Europe since the early 1990s and in the US since its 2009 approval, and today it’s widely regarded as the second most-used neuromodulator after Botox — backed by decades of clinical investigation and long-term safety data, including a 36-month study.

How does Dysport work?

Like all botulinum toxin type A products, Dysport works by blocking the release of acetylcholine at the neuromuscular junction — the chemical signal that tells a muscle to contract. With the signal interrupted, the treated muscle relaxes and the skin above it stops creasing, softening the wrinkles caused by repeated expression. The effect is temporary and wears off as nerve endings recover, which is why treatments are repeated a few times a year.

What does Dysport treat?

Dysport is FDA-approved for moderate-to-severe frown lines (glabellar lines) in adults under 65. In practice, injectors also use it off-label across the upper face — most notably forehead lines, where its broader spread is an advantage, as well as crow’s feet. Beyond aesthetics, Dysport is also FDA-approved for therapeutic conditions such as cervical dystonia and limb spasticity. Because it spreads more, it shines on large, flat muscles and is used more carefully near delicate areas like the eyes.

How fast does Dysport work — and how long does it last?

Dysport is known for a quick onset: many people see softening within 2–3 days, a touch faster than Botox. It reaches full effect around two weeks and lasts roughly three to four months, after which movement gradually returns and a repeat treatment maintains the result. As with any neuromodulator, duration varies with your metabolism, the dose, and muscle strength.

How much does Dysport cost?

Dysport is priced per unit — typically about $4–$8 per unit, lower than Botox’s per-unit price. But because Dysport uses more units (roughly 2.5–3 of its units per 1 Botox unit), the total cost for treating an area is comparable — most single-area sessions run a few hundred dollars. As rough guides, frown lines often take 30–50 units, the forehead 30–50 units, and crow’s feet 24–60 units per side. Galderma’s ASPIRE Rewards loyalty program offers savings and rebates. Always compare the price to treat your specific area rather than the per-unit rate, and see the cost guide for area-by-area ranges.

Dysport vs. Botox: what’s the difference?

Both are botulinum toxin type A and produce similar results, but Dysport tends to act faster and spread more (favoring large areas like the forehead), while Botox stays more localized for precise work and carries more FDA-approved facial indications. Their units are not interchangeable — about 2.5–3 Dysport units equal 1 Botox unit. For a full side-by-side on onset, diffusion, units, and cost, see Botox vs Dysport.

Is Dysport right for you? Safety and candidacy

Dysport is a good option for healthy adults who want to soften dynamic wrinkles, and it’s a particularly common pick for the forehead or for patients who want results a day or two sooner. Most side effects are mild and temporary — pinpoint bruising, redness, or a brief headache — and a temporary eyelid or brow droop can occur if the product reaches a nearby muscle. Like all botulinum toxins, Dysport carries an FDA boxed warning about the rare spread of toxin effects. It isn’t recommended for people allergic to any botulinum toxin product (or to cow’s milk protein, which Dysport contains), those with an infection at the injection site, or anyone with certain neuromuscular disorders; if you’re pregnant or breastfeeding, discuss it with a physician first. See the side effects guide for details that apply across neuromodulators.

Dysport results: what to expect

Expect a gradual softening rather than an instant change — movement lines ease over the first several days and look their smoothest at about two weeks. Done well, the goal is a refreshed, rested appearance that keeps natural expression, not a frozen look; that comes down to conservative dosing and good placement. Dynamic lines respond best, while deep lines etched in at rest soften but may not vanish, which is when injectors add skincare or other treatments. Maintaining a regular schedule keeps results consistent and can make lines less pronounced over time.

What to expect at a Dysport appointment

A visit starts with a consultation: the injector reviews your history, asks about your goals, and watches how your muscles move. The injections take only about 10 to 15 minutes using a fine needle, with optional numbing cream and no real downtime — you can return to your day, though injectors typically advise staying upright and not rubbing the area for a few hours. Because Dysport works fast, you may notice changes within a couple of days, with a two-week follow-up to fine-tune if needed.

How to choose a Dysport provider

As with any injectable, your result depends most on the injector. Choose a licensed, experienced provider — a board-certified dermatologist or plastic surgeon, or a trained nurse injector under medical supervision — who uses authentic product, understands Dysport’s diffusion and unit conversion, and does a genuine consultation. Find and compare qualified providers near you to get started.
