Q: Is There Any Help to Remove a Deep Furrow in Forehead
A: Botox & Dysport are paralytics which will ultimately eliminate the wrinkle
As stated above the paralytics will eliminate the wrinkles, however it may take 3-4 treatments to see the complete resolution of the wrinkle. It is important not to allow the muscles to get to the point that they function, so you will need to be sure to reinject every 3.5-4 months, as soon as you see any motion what so ever. If you are in a rush, you can certainly fill the crease to reduce the appearance until the paralysis of the muscles has taken effect.
Best!
