What type of liposuction is best when doing fat transfer? I’m reading that Vaser is best, but hardly anyone does it around me.

Most practitioners who do a lot of fat transfer and grafting do not use Vaser.  There is no evidence whatsoever showing that it provides better results.  Gentle handling of the fat and careful grafting technique are far more important. rRather than shop for a technology, shop for a provider with good reviews, results and experience. 

Hello dear!!
Thanks for the question and provided information as well. 
Unfortunately, without pictures, it is very difficult to give you a proper answer. l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)
