I bought 50 units of the Dysport from groupon in early Nov 2015 and redeemed it at the end of Nov, had the 50 units injected between my eye brows and forehead, no results were seen and after 2 weeks (begining Dec) I called back and they had me come by to get another 50 units which cost me another $119 and finally it seemed to work. But now approaching mid Jan 2016 and It already wore off. This stuff does NOT last 3-4 months like promised :( I guess I got 2 bad batches of Dysport, I will not put another $119 into something that did not work for me...Out $238.00 for product that only lasted a little after a month or so....The only upside to all of this was the staff was very friendly and inviting.
