Your dose can't be correct.
5 units of Dysport is not enough product to see any change. It is more likely that you were treated with 75-100 units of Dysport. The problem is not the Dysport, it is the patter used to inject the Dysport. Your doc is paralyzing the central forehead and this is causing the muscle recruitment on the sides of the forehead which is what caused the spock forehead.
I recommend that you read about my microdrodroplet botulinum toxin forehead lift so you can better understand a better approach for doing treatment.
I am surprised you saw anything from 5 units of Dysport. For the forehead the average is 40 units or more. With only 5 units I would suspect you would see absolutely no change and any change would be gone within weeks.
