I also admit that effect depends on doctors experience and the dosage. The dose of Botox I received was most likely not enough, as it did not smooth out my frown lines between the eyebrows. I felt like I just waisted my money on it. So, in 2.5 months I had the procedure redone with the Dysport and voila! The 11's were gone, the undereye lines smoothed out, as well as my forehead. So, 9 months later I'm going to have Dysport here in the US, hoping that the doctor will be as experienced and the dose will be right!
