Switching from Dysport to Botox?

I recommend that you wait at least two weeks to see the full results from Dysport.  If at that time, you still do not see results, then it is fine to use Botox.

I would wait until the Dysport effect is gone before you add Botox as it might confuse the issue if you don’t get a good result. If there is Botox and Dysport in the same area it would be hard to judge the effectiveness. It is possible that your physician just needs to adjust the dose of Dysport and give you a few more units here or there. It is a very similar product to Botox.

You do not have to wait to switch between the two. As long as you feel you can still move those muscles after Dysport for about 2 weeks, then you can try Botox and vice versa.

If you have had Dysport or Botox injected and the result is suboptimal, if it has been overdone -- you may have to wait until it wears off.  If the result is awkward or less than desirable, see a qualified plastic surgeon and theycan help improve the result.

Wait at least 2 weeks to see the full results from Dysport.  If not satisfactory after two weeks, you may proceed with Botox.
