Liposuctioning your lower cheeks is always a risky endeavor. Liposuction can create dimpling, and contour changes that usually is not a major deal when it is in your tummy or butt. But when it is in your face, the significance increases greatly. And that is just with traditional liposuction. When you add Smart Lipo to the mix, with their use of lasers during the liposuction that have less general use in terms of the time it has been available to the market and experience among surgeons, you are going into unknown territory, in my opinion. The risks would be higher. If you do decide to go through with it, I would tell your surgeon to be very conservative and that you don’t mind doing it again if you have to. Less is better many times.
