Using vaser for buttock fat grafting has NOT been shown to effect absorption. I do not use vaser, or any other technique other than tumescent liposuction. In my opinion, the other techniques will time and cost to the patient, but will not effect the outcome. I have performed fat grafting to the buttocks many times with great success.

Dr Bruno answer is right on. The Vaser is low wattage ultrasonic sound waves that explodes the fat cells thus making them non viable to be transferred.
