Most of it is aspirated (suctioned) out as a last step in the procedure. The fat cells are emulsified by the VASER Lipo and they are converted into a thick, oily liquid. The liquid that is not aspirated on the day is eliminated naturally through your lymphatic and blood systems over the subsequent few weeks. Traditional Liposuction scrapes the fat and vacuums it out, leaving subcutaneous hollows and loose skin.
