I like both Botox and Dysport. I'll be honest in saying that I use a lot more Botox than Dysport because of the brand recognition. A lot of people come in asking about it.
But I tell people it's like Pepsi and Coke. They're both great products, they both work. If one were ever more affordable, I probably would chose that one.
Botox tends to kick in in about a week, and it lasts about three months. Dysport actually kicks in a few days sooner, but it still lasts about the same amount of time. But they're both great products, I have no problem using either one.
