What’s the difference between Dysport® and Botox®?
Both brands have very similar modes of action. To keep things very simple, at the site of injection, the drug blocks the signal between the nerves and the muscle, so the muscle can’t cause wrinkles for a period of time.
Dysport® and Botox® units are not equal, the ratio of Dysport® to Botox® units is generally 2.5:1 (2.5 times more Dysport® units per 1 unit of Botox®).
The active ingredient (Botulinum toxin A) is the exact same in both medications, however the protein structure surrounding each molecule is slightly different.
Regardless of which product you use, full effect still takes two weeks. The effects of Botox® are usually noticed within 3-5 days. There are some clinical studies suggesting Dysport® can show results as early as two days. I will stress at this point that, from my experience, what is true for one client will be different for another.
The effects of Botox® and Dysport® both last about the same amount of time, up to 4 months. Clinical studies have shown that the quantity of the active Botulinum Toxin A injected determines the duration of action, rather than whether it was Botox® or Dysport® injected.
You may have heard that Dysport® spreads slightly further from the site of injection than Botox® does. This is a myth, particularly when applying the products recommended dilutions. However we do know that both products can spread from the site of injection. We also know this risk is higher as the dose increases.
