Am I a good candidate for Bodytite? Would Lipo and a Mini Tummy Tuck be a better option? (Photos)

You will likely get the best results from combining all 3 you listed. Start with liposuction, followed by Body tite to the upper part of your abdomen (above your belly button) and a mini tummy tuck to address lose skin below the belly button. We call this a RAMA (radiofrequency assisted mini abdominoplasty) at our practice.

You appear to be a great candidate for a standard tummy tuck with liposuction for contouring. Because you have had four children you most likely have muscle separation (diastasis recti) which can only be partially corrected with a mini tuck and not corrected at all by BodyTite. A standard tuck will address the separation, and remove excess fat and skin. The result will be smoother, tighter tummy. I've included a video I hope you find helpful.

BodyTite may be a good option if you have mild to moderate skin laxity and localized fat, especially if you're looking for less downtime. When combined with liposuction, it can improve contour and skin tightening.
If you have significant loose skin or muscle separation from multiple pregnancies, a mini tummy tuck may provide more dramatic results. The best option depends on your skin quality, fat volume, and desired outcome.
