What is the difference between Botox and Dysport?

Last updated: June 1, 2022

If you are considering getting cosmetic treatment to smooth out your wrinkles, you may be wondering if Botox or Dysport is the better choice for you. Both of these treatments use botulinum toxin type A to relax the muscles that cause wrinkles, but they have some key differences.

In this blog post, we will discuss the pros and cons of Botox and Dysport so that you can make an informed decision about which treatment is best for you.

What are Botox and Dysport?

Botulinum toxin type A is a neurotoxin that is used to smooth out wrinkles. It is produced by the bacteria Clostridium botulinum and can cause paralysis if it is ingested.

Botox and Dysport are both treatments that use botulinum toxin type A to relax the muscles that cause wrinkles. Botox was the first treatment of its kind and was approved by the FDA in 2002.

Botox has become the most popular form of the Botulinum toxin and is always the first introduced to the market.

Dysport was approved for public use in 2009, although it has been used in Europe since 1991. The main difference between Botox and Dysport is the size of the molecule. The botulinum toxin molecule in Botox is larger than the molecule in Dysport.

How do Botox and Dysport work?

The toxin Clostridium Botulinum is the same toxin responsible for botulism but if exposed to small amounts it can temporarily paralyze muscle tissue. Botox works by injecting the botulinum toxin type A into the muscles that cause wrinkles. This relaxes the muscles and prevents them from contracting, which smooths out the wrinkles.

Different units of Botox and Dysport can be used in order to achieve more results. Over time, too much exposure to the toxin can cause the face to become permanently paralyzed.

Advantages of Botox

Botox is a generally more applicable formula and it can be applied to several places around your face and head. Below are a few of the advantages of using Botox over Dysport.

Multiple Uses

Botox has been approved for multiple uses in the face and head as opposed to Dysport which only focuses on one area of the face. Because of this, Botox has become a more popular form of injection and has been more widely used.

More Potent

Botox has one of the most potent forms of the Clostridium Botulinum toxin and you don't have to use much in order to get the desired results. This is different from Dysport which needs about 3 times more of the toxin in order to get the same results you would get from Botox.

This doesn't mean that Botox is more effective, simply that it requires fewer units to have the same results.

Advantages of Dysport

Dysport was the second brand to be federally approved for use to reduce wrinkles and fine lines but the brand targets a very specific area of the face. Here are all the advantages you can expect from Dysport versus Botox.

Onset Is Quicker

Even though Dysport isn't as potent as Botox you can still expect to see results much quicker.

Patients typically report seeing reduced wrinkles and fine lines only after a couple of days. Compare that with Botox which takes up to a week for people to see results.

Best For Glabellar Lines

Dysport has only been approved to treat the area in between the eyebrows, known as the glabellar lines. This area is where you will see the "angry 11" or the two vertical lines that burrow deeply into the skin.

Dysport is able to treat glabellar lines because of the dispersed and wide coverage the structure of chemical components.


Dysport will not have the same potency as Botox but you can expect it to be a lot cheaper. The costs will depend on the amount of Dysport you need as well as the area being treated.

If you don't believe you need a lot of support reducing wrinkles and fine lines you should see good results with Dysport.

Disadvantages of Botox

Although Botox has been the longest and most trusted form of the Clostridium botulinum toxin, there are still some disadvantages you should expect.

More Expensive

The Botox formula is quite rich with the Clostridium botulinum toxin so you can expect it to be more expensive. The costs will depend on the amount of Botox you need as well as the area being treated.

If you want to cover multiple areas of your face or head, be prepared to spend a little more money for Botox than Dysport.

Slow Moving

The potent formula of Botox means that it stays within the same general area for longer period of time compared to Dysport. This helps smaller areas of your face get treated with the toxins but it also means that it will take a little longer to see results.

You can expect to wait up to a week before you start seeing any changes in the appearance of your wrinkles and fine lines.

Disadvantages of Dysport

Dysport may be faster acting but there are some weaknesses you can expect when using the brand.

Faster Moving Toxins

Because Dysport is more diluted than Botox you should expect the toxins to disperse more quickly. This means your results will last just as long but they won't treat smaller areas nearly as effectively.

Better for Larger Areas

If you want to treat your forehead or the area between your eye brows then you'll want to use Dysport. The dilution of the formula means it spreads to more areas rather than staying in one central location.


Does Dysport last longer than botox?

Both Dysport and Botox injections can last for around 3-4 months, but the results may vary from person to person. The onset will be faster with Dysport

Can a medical assistant do botox?

Medical assistants are allowed to inject both Dysport and Botox. They must be licenced professionals by the state.

Can you get botox while pregnant?

Recommendations will change from doctor to doctor but the FDA has concluded there is not enough evidence at this time to deem it safe or unsafe.

Are there Botox injection in stomach side effects?

Botox in the stomach can cause severe pain and swelling as well as nausea and indigestion.

Differences between Botox and Dysport

There are several differences between Botox and Dysport like onset times, potency, and use case but both contain the Clostridium botulinum toxin and they last about the same length of time. Which brand you get will depend entirely on your preference and needs.
