As reported by researchers, the main differences between Botox® and Dysport ® is the onset of action. Dysport ® tends to show effect sooner, working within 2-5 days. Botox® takes slightly longer, starting in 4-7 days. However, it is recommended that no additional units be added to the same treatment area within 2 weeks to avoid overtreatment.

Botox® monopolized the U.S market for many years until 2009, when Dysport® was approved by the FDA.  Dysport® however, was used in Europe many years before it was made available in the United States.

The units of measurement for Botox are different from Dysport. When comparing doses, it’s important to note that they are not interchangeable. For example, 3 units of Dysport is roughly equivalent to 1 unit of Botox.

Botox has a larger molecular size, which means it tends to stay localized to the area where it’s injected. This makes it ideal for treating specific lines and wrinkles.

Dysport has a smaller molecular size and a different formulation, allowing it to spread more easily to surrounding muscles. This can be beneficial for larger treatment areas, such as the forehead.

Individual response to each product can vary. Some patients may find that they prefer one over the other based on their unique results, treatment experience, and how their skin responds.

Ultimately, the choice between Botox and Dysport should be made in consultation with a qualified medical professional who can assess your specific needs and desired outcomes. Both treatments are effective for reducing the appearance of wrinkles and achieving a more youthful look, so understanding the differences can help you make an informed decision.
