Do I need a tummy tuck? Full or mini? Or will J Plasma help? (Photos)

I would be very concerned about doing anything other than a full tummy tuck to get you looking your best.  While I am excited about new technology to tighten the skin, I have not seen results that come even close to a tummy tuck by any liposuction,  laser, or other applied energy technology.

You
are an excellent candidate for an abdominoplasty with mesh reinforcement, if
you are not planning future pregnancies. 
The typical tummy tuck tightens the lining of the muscle called
fascia.  The use of mesh reinforces this
making it stronger than the original. 
This helps produce a more hourglass figure and maintains weight loss.Best Wishes,Gary Horndeski, M.D.

Hello and thank you for your question!
In response to your question and based on your photos, I would recommend a full tummy tuck. Liposuction does not address skin elasticity and I believe a full tummy tuck would be the best option to address your concerns. Be sure to set up an in person consultation with a plastic surgeon who specializes in this procedure. 

Good Luck!
