12 thread lifting over 2011 and 2012/informed it last 2-3 years, collagen produced around thread, no harm/absorption. over time I noticed the effect did not last long. 6/19/12 is my surgical date. I got informed of another extra procedure by the surgen after surgery. My threads were taken out. Upon asking why, he answered he did it because the threads did not consistent with his way of doing face lift. I speculate that my lower parts look more dragging for this, but I am not sure. Any opinion?
