Effects of Botox vs Dysport
For the most part, Botox and Dysport act the same. Most people will not notice a big difference between treatment with Botox vs. Dysport. There are a few potential differences. The first is with onset.
Dysport is said to work faster than Botox (by a few days). However, it is still unclear how dramatic this difference is. For both Botox and Dysport, it takes up to a week to ten days to see the results. It can take up to two weeks to see the full effect. Touch-ups are sometimes needed after the two weeks to make sure the results are perfect. It is common to need a few more units on one side or the other to be completely even.
Some people say Botox lasts longer than Dysport. Again, it isn’t clear if this is indeed the case. For both of these injections, results last between three to four months on average. There are some lucky people whose Botox or Dysport injections last even longer. This is usually with people who have been getting injections for a long time, and their muscles have atrophied (weakened).
