Liposuction is an operation to remove fat. Nothing else. Aside from surgical removal (Facelift, Tummy Tuck, Butt lift etc), Skin tightens in response to an injury, the extreme example of which is a 3rd degree burn in which the scar tissue relentlessly pulls heads to the chest and forearms to the arms with thick cord called contractures. When injury takes place, scar tissue or Collagen in popular talk, is laid down and then remodelled. The degree of injury, its depth, your ethnic background will determine how much scar tissue is generated and how much pulling under the surface (IE "Skin Tightening") will take place. Obviously, it would be great if doctors knew and could predicatively deliver the amount of injury sufficient to cause skin tightening WITHOUT causing dimpling, irregularities, or worse, skin burns and contractures. Unfortunately, we do not. VASER liposuction may in some areas of the body (back, male breasts etc) deliver some skin tightening. But other devices on the market, such as laser liposuction devices (such as SmartLipo) purposefully heat the skin to get it to shrink. Unfortunately, shrinkage=skin injury and many patients having these procedures are also left with dimpling and irregularities. Conclusion - if you may be satisfied with mild to minimal skin tightening - get VASER liposuction from a Board certified Plastic surgeon (check www.PlasticSurgery.org). If you want TOTAL flattening, get a Tummy Tuck. I would NOT recommend Laser liposuction at this time to anyone not willing to accept the possibility of permanent dimpling and irregularities.
