I hope I can make you feel more enlightened rather than add to the confusion.
First, it is somewhat difficult to fully assess your situation based on your picture alone, but you appear to have some fat excess, some skin excess - particularly in your lower abdomen, and probably some muscle wall laxity. Liposuction procedures primarily address only fat excess, (with the possible exception of Smart Lipo which can get some increaed skin tightening-but is not a miracle device). A Mini tummy-tuck can take out skin laxity in the lower abdonem but does not address any laxity in the upper abdomen, and usally does not address muscle wall laxity. A full tummy tuck will addrss all three but is a significantly bigger surgical procedure with more downtime and bigger scars, but overall much greater change. You must decide, in consultation with your surgeon, which procedure, or combination of procedures, will best meet you needs in terms of quality of result, degree of downtime, and costs.
Liposuction, whether SmartLipo or not, of your abdomen, flanks, and chin would not be toxic. But a Tummy Tuck would likely get you an overall more dramatic result. A combination of SmartLipo of your abdomen combined with a Mini Tummy-tuck, could give you a reasonable result but with the understanding that you would still have some laxity of the skin in you upper abdomen and some residual muscle wall butge if no muscle tightening is performed.
So there's your not so simple but honest answer.
The notion that "tumescent" liposuction is "the" thing that provides the greatest benefit is utter hogwash. Everybody does tumescent liposuction, it is an integral part of virtually any liposuction technique performed today. Dermatologists don't do tummy tucks because they can't. Go see a reputable, experienced, Real Plastic Surgeon who is certified by the American Board of Plastic Surgery and has experience with all these procedures, and you and he/she can decide on a plan that best meets your goals, downtime tolerance, acceptance of scars, etc.
