What's the difference between Vaser liposuction and Ultrasonic liposuction? I am trying to decide which would be best for me. I am a very athletic young adult and I'm hoping not to be down for too long. Is the recovery shorter with the Vaser or the Ultrasonic? My plastic surgeon recommended the Ultrasonic. She said that my skin would have no prob rebounding, but if it means I'm down longer, I'd rather pay a little more for the Vaser. Please help.
