I got 1.5cc from Dana in June. I was told it would last for about a year due to the size of the particles, but I think half of it has already gone. And...real fillers should be applied at a place that is good at it. Since I put 1.5cc in with 0.5cc and 1cc two shots, the left side went in more :: I asked if it was really okay to put in two shots like that, but he said not to worry, and in the end.. haha, I was going to retouch it, but I'm just going to put the implant in once it all melts haha.
