When we talk about liposuction, it can be really confusing because there are a lot of good systems out there, and nearly every doctor has 1 or 2 favorites. Here are the types of liposuction:Traditional Liposuction - performed with a larger cannula, must be performed under general anesthesia due to aggressiveness, not as popular these days because there's no real advantage to it, typically seen used by "old school" plastic surgeonsMicroAire PAL (Power-Assisted Liposuction) - Vibrating, powered suction liposuction that can be done under local or general anesthesiaSAFE Lipo is a branded technique that uses PAL to encourage skin tighteningLaser LipoSmartlipo is the most brand of laser lipo right now - Newest version called Triplex has 3 different laser wavelengths and a safety control to prevent too much heat in any one area (older versions had less safety measures and that's why the system didn't gain popularity until more recently)SlimLipo was one of the best versions for a long time - was the first to really provide skin tightening, but is somewhat inferior to what the newest Smartlipo Triplex can achieve in terms of skin tighteningVaser Lipo - sometimes this is miscategorized as laser lipo, but really it's ultrasonic lipo; the ultrasound helps break up the fat prior to removal for more complete removal of fat, but there is no skin tightening componentYou can also create the same type of skin tightening and fat removing procedure as Smartlipo by combining ThermiTight, which is a surgical skin tightening procedure that uses radiofrequency (RF) heat instead of laser, with a liposuction procedure. I'm linking to our liposuction page below with more info on the different types of liposuction.In regards to whether laser lipo actually tightens the skin: Yes, for the right candidates it works really well, but not everyone is candidate. During the skin tightening portion of the procedure, whether you use a laser or RF, you're basically heating the skin from underneath. You run the wand under the skin and use heat-sensing cameras to ensure you're heating up the collagen enough to create a shrink-wrap effect while not reaching a too-high temperature or injuring the patient. But the ideal candidate needs to have good collagen structure within their skin in order to create significant results with a smooth, even outcome. Stretch marks are indications that the skin has been stretched so rapidly that the collagen structure below has ripped in two. So those with stretch marks really aren't going to see a good result. Anywhere there is lots of loose hanging skin, we know the collagen below has been significantly damaged, and likely won't respond well, either. So the patients who really see a good result from this have only mild to moderate loose skin. Which is why a tummy tuck or other body lift surgery is indicated for those with significant loose skin and/or stretch marks.Finally, the idea that fat will never return to any area on your body is pure myth. To understand why people mistakenly believe that, you need to understand a little bit about the way fat cells store fat and multiply. Everyone has a set number of fat cells. If you were to start gaining weight, those fat cells would start filling up their storage areas, and when you gained so much weight that you had maxed out the storage of your current fat cells, your body would build more fat cells with more storage space. At any given time, you do have fat cells with some extra storage space. So if we remove a bunch of full fat cells from your stomach, and you gain a little weight, your body will first max out storage in the fat cells in other parts of your body. But if you gain a lot of weight, your body will have to make new fat cells, and some of them will be in your belly again. Most patients don't regain so much weight after lipo that they start to build new fat cells, but if you do, this is a possibility.
