New and improved Macrolane?

Hi there, After taking the fillers out of the market for so long, I have found a doctor who claims there is a new high volume hyaluronic acid filler by NASHA Macrolane in the market, which is free of the other impediments related to the old material (fast absorption). Before jumping up and down with joy that finally I can get a quick and easy fix to my flat butt problem, I just want to make sure that this is indeed true, ready to use, and of course safe. Thank you in advance for your answer.
