Dysport for Patient Immune to Botox?

We believe there is a low probability that Dysport will work for you if Botox did not.  With that said, if Botox results are something that you still are very interested in attaining, then it's probably worth the risk of trying Dysport and failing.  

We would suggest going in and having a small area injected (maybe the area between the eyes) to see what the effect is.  While it's possible that you have developed a resistance to Botox in some manner, it's also possible that you were not injected correctly or that too little product was used previously.  Give it another shot and good luck!

I have answered this question before and will now repeat my explanation.

Dysport and Botox are both Botulinum Toxin type A products. They are, however, subtly different. It is this small difference that may account for Dysport working where Botox does not. In my practice I have treated a couple of patients that don't respond to Botox injections. They seem to be doing well with Dysport so far. Traditionally we have used Myoblock for these patients, but Dysport presents another options. I would recommend trying Dysport if you find that Botox is not effective.

I hope this info helps!

Chances of your getting a positive outcome from Dysport if Botox has not worked is very slight. The products are almost identical and both work the same way on the proteins that allow signals from nerve to muscle.
Most people end up with frown lines from unconsciously contracting the forehead muscles. One "old" way of combating that habit is to use a paper pasted over the wrinkled area (called Frownies). If you are consistent in using them, you can see some lessening of the frown lines.
If you do use them, pay attention to your skin and be sure to clean the area well after removing. If you have any skin irritation, stop using them.
