Dysport vs Botox - I've had both - El Dorado Hills, CA

Sticking with the Botox - I like it more for me personally.

UPDATE: I had a negative reaction to the last Dysport treatment - which I didnt initially realize was from this injection. My vision got funky, I thought my glasses were needing to be updated or something was wrong. I had a slight headache. Later, I developed a red itchy bump on the back of my thigh, I thought it was a mosquito bite, but then I looked and there were like four or five in a row, that was one hungry mosquito I thought! Then, I got a red blistery looking bump on my boob by my cleavage, I thought it was that dang mosquito again, they must be getting in the house. Over the next few days, these red bumps started popping up in a cluster only on my right boob, as soon as one would go down, a new one would pop up.. they didnt look like bites and they didnt really itch.. they were not pimples.. I was baffled. OMG, what is this? Too much detergent, soap..?? Are these chicken pox? Shingles? Herpes? I did some research and noted that many other people had similar reactions with the blurry vision, rash and headaches. Perhaps I had it too close to the previous Botox injection and it was too much in my system - who knows. I am apprehensive to do it again now.

I got another coupon for Botox at a competing center. Four months, in July 2011 after the above Dysport injection, I went to try Botox to see for myself what the difference was. The RN who did the injection said that the effects of the Dysport were gone -
It has been over six months and I can still feel the effects of Botox. In fact, they just started wearing off and I can frown again. For me, they seem pretty comparable, but I guess the Botox did last a bit longer. Could be the amount injected, the concentration or just a person's individual situation.
I went back last week for another Dysport, as I purchased a future injection and was unable to switch. This one seems to be kicking in rather quickly - my forehead is smooth again and I no longer look angry or confused all the time - LOL. Now I keep my anger on the inside, where it belongs... ha ha...
