When you look into botulinum toxin treatments at a dermatology or plastic surgery clinic, the name "Dysport" might catch your eye at some point. Searching for it online reveals that it is a botulinum toxin, which naturally makes you wonder if it is exactly the same as Botox. When you hear "We'll treat you with Dysport today" at a clinic, it can feel too awkward to ask "Why?" yet leaving you with a lingering feeling that there is something you do not quite know.

In fact, in many cases, getting either of the two without distinguishing between them will not cause any major issues. However, understanding that results can vary depending on the treatment area and your specific goals empowers you to ask that one extra question during your consultation.

They have similar ingredients, but there is a reason the products are different

Botox is manufactured by Allergan in the United States, while Dysport is produced by Galderma in France. Although both use botulinum toxin type A as their raw material, they differ in the size of their protein complexes and their manufacturing processes. While they work on the same principle of blocking nerve signals to the muscles after injection, differences arise in how they actually diffuse within the body.

Unit calculations are also different. Generally, 1 unit of Botox is equivalent to about 2.5 to 3 units of Dysport. Looking only at the cost per unit on a price list can be confusing, but the total cost required to treat the same area often turns out to be quite similar. If your first impression is "Dysport is cheaper" or "It's more expensive," it is a good idea to check the unit conversion first.

What does it mean that Dysport spreads more widely?

Since Dysport has a smaller molecular weight than Botox, it tends to spread more widely into the surrounding tissue after injection. This is referred to as its diffusion characteristic, which can be an advantage or a point of caution depending on the treatment area.

For broad areas like the forehead, Dysport's diffusion properties can naturally create very even and smooth results. On the other hand, in narrow and delicate areas like around the eyes, there is a possibility it could affect unintended nearby muscles, making the judgment of an experienced practitioner crucial for those areas.

Diffusion properties*: This refers to the range over which the product spreads to surrounding tissues after injection. It works smoothly and evenly over broad areas, but in areas requiring precise control, the practitioner's experience becomes a much bigger variable.

Depending on the area being treated, the exact same characteristic can lead to completely different outcomes. Rather than thinking "Dysport is bad because it spreads," it is more accurate to understand that the way it is utilized varies depending on the target area.

How about the onset speed and duration of the effects?

In many cases, Dysport tends to show visible effects faster than Botox. It is commonly noted that while Botox usually starts showing results in 3 to 7 days, Dysport can begin to take effect in about 2 to 5 days. However, this is an average trend and varies from person to person.

The duration for both products is widely known to be similar, averaging about 3 to 4 months. Some individuals feel that Dysport wears off a bit faster, while others report that it lasts much longer. Because duration is influenced by numerous factors—such as the dosage, muscle size, individual metabolism, and lifestyle habits—it is difficult to definitively say which one lasts longer. Even with the same product, everyone's experience is unique.

So, in what situations does a doctor choose one over the other?

The choice often naturally depends on the treatment area and your specific goals.

• Broad areas or larger muscles: For areas with a wider surface or greater muscle mass—such as forehead wrinkles, trapezius reduction, or calf muscles—the diffusion characteristic of Dysport can be highly beneficial.

• Areas requiring precise control: For narrow, highly precise areas like the corners of the eyes or mouth, many practitioners prefer Botox.

• When the effects are not what they used to be: Some people find that their response weakens after using the same product for a long time. In such cases, switching to a different product can be an excellent option. Since the protein structures of the two products are different, switching can often elicit a better response.

Rather than labeling one as superior to the other, it is more accurate to see that the most suitable option depends on the treatment area, your goals, and your personal response. Feel free to ask "Which product are you using?" during your consultation, and hearing the reasons behind the choice is always a great way to go.

While both are botulinum toxins, the choice of which one to use can be more important than you might think. Since results can differ based on the treatment area and your unique response, we highly recommend having a thorough discussion with your doctor during your consultation.
