Dear JRB. I have been in practice for 30 years and performed tummy tuck on well over 1000 patients. Only one patient (male) had skin tightening only, tummy tuck. The rest of my patients had skin and muscle tightening tummy tuck surgery, because it is extremely rare to see patients after child delivery or significant weight loss, that the skin alone is loose without the abdominal muscles as well. They almost always go hand in hand. One of the biggest benefits of the muscles tightening is weight loss , since you can eat as much as before surgery and your appetite is significantly reduced. You have to realize that not all results are the same, because experience, skills and aesthetic eye, are critical for good outcome. So, do your due diligence carefully and choose your surgeon wisely, to avoid bad result and need for corrective surgery , which doubles the cost and recovery time. Always, consult with experienced board certified plastic surgeons who operate in accredited surgery center for your safety. Most importantly, check the before and after pictures in the photo gallery, to make sure that they are numerous, consistent and attractive with flat stomach, tight and youthful looking skin, nice 'inni' belly button. improved body posture and low scar. Best of luck, Dr Widder
