Dysport® vs Botox® is a choice between two separate prescription neuromodulators. Each has its own U.S. Food and Drug Administration (FDA) label, and each is dosed in its own units, which cannot be swapped one for one. Neither is the clinical winner. The better fit depends on the area being treated, your history with neuromodulators, and your provider's judgment after an exam.
Both products block the nerve signal that tells a muscle to contract, which softens the lines that muscle creates, such as the frown lines between the brows. The differences sit in the labels, the units, the ingredients and the way a provider matches a product to a person, and each one is something you can ask about before you book. We would rather you walk in knowing what to ask.
What Dysport and Botox Have in Common
The two products share more than the search results suggest, and most of it comes straight from their labels.
- The Botox Cosmetic label and the Dysport label each describe a botulinum toxin type A product.
- Each lists the temporary improvement in the appearance of moderate to severe frown lines between the eyebrows (glabellar lines) in adults.
- A boxed warning titled Distant Spread of Toxin Effect appears on both, and the risks section below covers it.
- A licensed provider evaluates you before either one is used.
Dysport vs Botox: What the Two Labels Say Differently
Reading the Botox Cosmetic prescribing information and the Dysport prescribing information side by side turns up a few differences that matter to patients.
The Botox Cosmetic Label
- Lists four treatment areas in adults: frown lines between the brows, lines at the outer corners of the eyes, forehead lines and platysma bands in the neck.
- Names human albumin and sodium chloride as its inactive ingredients.
The Dysport Label
- For appearance, lists frown lines between the brows in adults under 65. Its medical uses are listed separately.
- Names human serum albumin and lactose as ingredients.
Labels get revised over time, so ask your provider which areas each product is currently labeled for before you decide.
Why Unit Counts Do Not Translate Between Products
Units are the first place a quote for one product and a quote for the other stop lining up.
The Botox Cosmetic label says its units cannot be compared to or converted into the units of any other botulinum toxin product. The Dysport label says its potency units are not interchangeable with other preparations. A higher unit count on one quote therefore does not mean more product than a lower count on the other.
Quotes can also be built in different ways: by the unit, by the treatment area, or by the visit. Ask each practice for the product name, how the price is set, and what is quoted separately, such as extra areas or follow-up visits. Prices change, so this post leaves figures out.
How a Provider Chooses Between Dysport and Botox
There is no scoring chart. A provider weighs a short list of factors, and the answer can differ from one patient to the next.
The Treatment Area
The two labels list different areas, so the area you want treated is where the conversation starts. Your provider can tell you what each label covers for it.
Your History
If you have had a neuromodulator before, the product, the date and how it went for you all count. A record from your last provider helps.
Allergies and Health History
A past reaction to a botulinum toxin product or any of its ingredients, or an infection near the treatment area, can rule a product out. Tell your provider about all medications and supplements, and follow their instructions.
Your Goals and Timeline
How much movement you want to keep, which lines you want softened and any date you are planning around all shape the plan. Dose and placement keep a result from looking overdone, and our post on overtreatment covers the signs.
The provider's own experience is a factor too. A provider who injects both products can speak from their own work with each, so how often they use each one is a fair question. The answer shows how they decide, and it is on the question list below.
Risks and Side Effects to Know About
The safety information on both labels opens with the same boxed warning, so the main risk is shared.
Distant Spread of Toxin Effect
The labels warn that the effects of the toxin may spread from the injection area. Reported symptoms include generalized muscle weakness, double vision, drooping eyelids, trouble swallowing, a hoarse voice, slurred speech, loss of bladder control and trouble breathing.
Each label states that swallowing and breathing difficulties can be life threatening and that there have been reports of death. If you have trouble swallowing, speaking or breathing after treatment, get medical care right away, and call 911 in an emergency.
Other Reactions the Labels List
The Botox Cosmetic label reports eyelid ptosis, a drooping upper eyelid, in its frown line studies. The Dysport label lists headache, injection site pain and injection site reaction among its most common reactions. Each label says reaction rates from one product's trials cannot be directly compared with another's, so we do not line the numbers up.
Who Should Not Be Treated
Both labels list hypersensitivity to botulinum toxin products or their ingredients, and infection at the planned injection site, as contraindications. The Dysport label also names hypersensitivity to cow's milk protein. Your provider can go through the risks that apply to your health history and treatment area before you decide.
Questions to Bring to Your Consultation
At Citrus Aesthetics, a consultation with Jessica Cvetic, PA-C, BS, MPAS, covers your goals and the risks and benefits of treatment, and she will decline treatment if the risks outweigh the benefits for you. The questions below work at any practice, and we welcome them at ours.
- Which product do you recommend for my treatment area, and why?
- How often do you use each one?
- If I have had a neuromodulator before, how does that change your plan?
- How is the quote built, and what is quoted separately?
- What should I watch for after treatment, and who do I contact?
- Does anything in my health history, allergies or medications change the options?
Take the Dysport vs Botox Question to Your Consultation
The Dysport vs Botox decision gets easier once you know where the real differences sit: labeled treatment areas, units that do not convert, ingredients and your own history. None of them puts one product ahead for everyone, which is why the decision belongs in an exam room and not on a comparison chart.

Frequently Asked Questions
Is Dysport the same as Botox?
No. Dysport and Botox are separate products with separate FDA labels, and each label describes a botulinum toxin type A product. Their units are not interchangeable, and the labels list different treatment areas and ingredients.
Which is safer, Dysport or Botox?
Neither label ranks one as safer. Both carry the same boxed warning, and both are used after an exam by a licensed provider. Your provider can explain which risks apply to your health history and treatment area.
Is Dysport cheaper than Botox?
Not necessarily, and the unit count cannot settle it. Each product has its own units, so a lower number on one quote does not mean less product than a higher number on the other. Ask for the product name, how the price is set and what is quoted separately before you compare.
Does Dysport work faster or last longer than Botox?
How fast Dysport or Botox starts working and how long it lasts varies with the person, the area and the dose, so we do not quote day counts or months for either one. Your provider can tell you what to expect for your own treatment.
Can I switch from Botox to Dysport or the other way around?
Ask your provider, who chooses the dose for the product they use instead of carrying over the old unit count. Tell them which product you had, roughly when, and what you noticed.
