Which would you recommend; Radio frequency treatments for loose abdominal skin or Tummy tuck? (photos)

Given that you have minimal skin laxity with very little excess fat, I believe you would be a great candidate for noninvasive abdominal contouring. I prefer RF treatments with the Venus Legacy but any multipolar RF machine should be able to provide you with skin tightening given you undergo the full treatment course. Good luck!

We have seen great success in treating stretch marks with radio frequency in our office.  I would recommend trying that, if you don't see improvement then you may consider a mini tummy tuck.
