Can Dysport suddenly stop working?

Dysport (and Botox and Xeomin) can be used to relax muscles that cause wrinkles or folds.  It is common to treat the frown lines between the eyebrows (the 11's).  In many cases, using Dysport alone can improve the lines enough.  In some people, if there is also a depression present, a filler can be used for further improvement.  If you only have a line without a depression, you may not need a filler.  An examination of your frown could determine if the Dysport is working or not.  If the Dysport is working, you should not be able to move the frown muscles.  If there is a depression, it is possible that this could still be present even with the muscle relaxed from the Dysport.  In this case, a filler could help.  

If your Dysport has always worked in the past and there has only been an issue with this last treatment then it was likely due to the Dysport itself or the injection technique. It is unlikely that it suddenly would no longer work for you. If the Dysport was old, reconstituted incorrectly or injected with improper technique then your results can be impacted.

Dysport should not stop working as you cannot develop a tolerance to the drug. Maybe the mix was too dilute and that is why the units did not take. Ask your provider. Hope this helps. JB

This is difficult to answer without pictures. Deeper wrinkles need a combination of Dysport combined with fillers along with lasers and microneedling/prp to get improvement. This combination may be needed to get your desired results. Best, Dr. Emer

There are many reasons why botox may seem to not have an effect. One of them is having less than recommended units. There are also cases where the muscles that were not injected with botox are becoming more active thus creating new lines. Moreover, there are cases when lines simply become too deep for botox to be sufficient. It may also be that the botox was too diluted. Discuss it with your doctor to know more.
