Thank you for your question. Unfortunately, there is no way to remove it. You will have to wait until the effect wears off - this typical lasts approximately 3 months. Injection of neuromodulators such as Botulinum toxins to the lower eyelids typically is not recommended. Best wishes!
Unfortunately, there is nothing that can be done to reverse Dysport. Luckily, the problem is temporary and will last a few months. It sounds like the injection was improperly placed or dosing was not properly measured. Often the aging around the eyes needs a combination of Dysport with fillers. So perhaps, adding fillers might make things look better.
Dysport and Botox both have issues in the lower eyelids because they can cause wrinkles and make the eyes look tired. I don't recommend neuromodulators be done there. Now that you have it there, unfortunately, you have to wait for it to go away. There is no way to remove it. It has to just run its course, which should be about 3-4 months.

Unfortunately, the dysport effect will have to wear off. It takes a few months for the neuromuscular junctions to "heal" after the dysport effect has taken place.
