I tried Dysport the first time and it was initially fast acting but lasted less than a month. I went back and they gave me two to three times as many units. I swear it has been ONE MONTH and it is literally completely gone.
I also noticed that it doesn't smooth your forehead like botox. It created vertical lines and weird pulling. I have heard that dysport has been available in Europe for many years and it is not very popular.
I am getting botox tomorrow... just one month after my boat load of dysport injections. $665.00 dollars down the tube! Unless you have perfect skin I DON'T recommend it.
