Quick answer: Dysport and Botox are both botulinum toxin type A injections that relax the muscles behind expression lines. Results look very similar and last about three to four months. Dysport tends to spread a little more, which can suit broad areas like the forehead, and some people notice it working a day or two sooner. Botox has more FDA-approved areas and more precise, targeted spread. |
If you’ve had Botox before and someone suggested Dysport, or you’re comparing prices, it’s natural to wonder whether one is better. The honest answer is that neither is better for everyone. They’re close cousins, and the right choice depends on the area being treated, how your body responds and what your injector is most comfortable with.
What is Dysport?
Dysport (abobotulinumtoxinA) is a prescription wrinkle relaxer made by Galderma. The FDA approved it for cosmetic use in 2009, for moderate to severe frown lines between the eyebrows, called glabellar lines. It works the same way as Botox: it blocks the nerve signal that tells a muscle to contract, so the lines created by that muscle soften.
Injectors also use Dysport off-label in other areas, such as the forehead and crow’s feet. Off-label use is common and legal when a licensed provider judges it appropriate, but it’s worth knowing which uses are FDA approved.

The real differences that matter
1. Spread
Dysport is dosed and diluted differently from Botox, and it tends to spread a little further from each injection point. In a large, flat area like the forehead, that wider spread can give a smooth, even result with fewer injection points. Near the eyes or brows, where precision matters most, many injectors prefer Botox’s tighter spread to reduce the chance of affecting a nearby muscle.
2. Onset
Some people notice Dysport taking effect a day or two sooner than Botox. Studies are mixed, so don’t count on it, but it can help if you have an event coming up and you’re short on time. Either way, book at least two weeks ahead.
3. Units and price
You’ll see much higher unit numbers for Dysport, which can look alarming. It doesn’t mean you’re getting more product or a stronger dose. The units simply aren’t measured on the same scale. Compare the total cost per area, not the price per unit.
4. How your body responds
Some people find one product lasts longer or works better for them. A small number of people develop resistance to one toxin over time, often after very frequent, high-dose treatment. Switching products is a reasonable step if your results start fading faster than usual.
Who is Dysport a good fit for?
Dysport tends to work well if you:
- Want to soften frown lines or forehead lines.
- Have a broad forehead and want an even, natural result.
- Feel Botox has started wearing off sooner than it used to.
- Have an event and want results to start as early as possible.
The same safety rules apply as for Botox. Dysport isn’t recommended during pregnancy or breastfeeding, with certain nerve or muscle conditions, with an infection at the injection site, or if you’re allergic to cow’s milk protein, since Dysport may contain trace amounts. Our Botox candidate guide covers who should wait in more detail, and the same points apply to Dysport.
What results look like
When the dose is right, you still look like yourself, just more rested. Lines between the brows and across the forehead soften, and makeup sits more smoothly on top. Dysport doesn’t replace volume, so if you also have hollowing or deep folds, it’s often paired with dermal fillers. For texture and fine crepey lines, laser skin resurfacing works on the skin surface in a way wrinkle relaxers can’t.
Side effects
Side effects are similar to Botox: temporary redness, small bruises, a mild headache and, less often, a heavy brow or droopy eyelid for a few weeks. Dysport also carries an FDA boxed warning about the effect spreading beyond the injection site. Trouble swallowing, speaking or breathing after any toxin treatment needs urgent medical care.
How to choose
If you’ve never had a wrinkle relaxer, either is a reasonable start, and your injector will suggest one based on your anatomy and the area. If you’ve had good results with one, there’s no reason to switch. If results are fading faster than they used to, or you want an even result across a wide forehead, Dysport is worth discussing.

Frequently asked questions
Is Dysport stronger than Botox?
No. Dysport uses more units, but the units aren’t comparable. At the right doses, the two give a similar strength of effect.
Does Dysport last longer than Botox?
For most people, both last about three to four months. Some individuals find one lasts a little longer for them, but there’s no consistent winner.
Can I switch from Botox to Dysport?
Yes. Your provider will convert your dose, since the units don’t match one to one. Many people switch without any issues.
Is Dysport cheaper than Botox?
Pricing per unit isn’t comparable. The total cost per area is usually similar. Ask for a per-area quote when comparing.
Can Dysport treat crow’s feet?
Many injectors use it there, but it’s an off-label use. Dysport’s FDA approval covers frown lines between the brows.
