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.

Liposuction for Brazilian buttock lift
I recommend traditional liposuction under low suction to preserve the amount of fat cells to be used for a fat transfer to the buttock (Brazilian buttock lift). Vaser is useful for liposuction or sculpting but not necessary for fat transfer. I prefer the BodyJet system to harvest the fat in a more gentle fashion thereby preserving more fat cells and giving a better result.
Vaser vibrates the fat cells like someone grabbing a bunch of grapes and shaking them so fast they start falling off the vine. The fat cells begin to implode, leaving behind fat cells that have been reduced to a near liquid like mixture. Vaser is for sculpting and high volume removal. Vaser is especially good at ethnic skin fat removal where fat is very dense and traditional liposuction falls short.

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.
