Fat transfer is the process of collecting fat via liposuction either manually or with a special cannula in the tickle liposuction process and then transplanting it into another area in your body.  This is especially useful to augment breasts naturally, transfer fat to the buttocks, face, and hands.  With today's technology and knowledge about stem cells, the success rate is much better than it was forty years ago. 
Will publish photos soon, for now link to this web site for photos and click on before and afters.  I plan to publish before, immediately after, 6 mos, and 1 year results.  Results vary depending on the quality and number of the stem cells in each person.  Typically one can expect at least a 30% improvement from baseline.
