How long does it take dysport to completely wear off? I still have a very heavy feeling with my eyebrows 6 months later.

In general 6 months is enough time for Dysport to wear off. Few patients have seen a longer duration of action

The average time Dysport lasts is between 3-4 months. But remember this is just an average. Some people will be shorter, some longer. I have a patient for whom Dysport lasts 9 months. It will wear off eventually. "This answer has been solicited without seeing this patient and
