Can't speak for others but Dysport works faster and lasters longer than Botox for me. I use it in the forehead area for glabellar lines. Use a 3-1 ratio so 60 units of Dysport versus 20 of Botox. Some providers try to get by with a 2 or 2-1/2 ratio. Go for 2-1/2 or 3. Not many rebates lately but the pricing seems better.
