What do I need to do to get rid of this type of skin? (photos)

Thank you for your question and photos. Unfortunately, no amount of exercise is going to improve skin quality or remove stretch marks. A TT will remove all excess skin and create a flat tummy. Your sides will also be improved by cinching them in creating a much coveted waistline. I like to employ mesh to give patients the flattest abdomen possible and long term results. Mesh is to be considered only if you are done with pregnancies. Please view the article below to learn how the mesh works in conjunction to TT surgery. I hope this helps.Best wishes,Gary Horndeski M.D.

The only way to remove loose skin of the abdomen is by performing a tummy tuck (abdominoplasty). In the performance of a full abdominoplasty, an incision is made from one hip to the other. The incision is carried through the skin and fat layer and stops at the muscle layer. At this level the skin and fat layer is elevated off of the underlying muscle layer. This elevation is continued up to the belly button. An incision is then made around the belly button to keep it in it's normal location allowing the skin and fat layer to continue to be elevated up to the rib margin. Very often tightening of the muscle layer is then accomplished before removing the excess skin. The loose skin and fat layer is then pulled down snugly and the excess skin and fat is then removed. The belly button has not been moved or removed. It is still in it's normal location underneath the skin and fat layer. An incision is made over the belly button and it is pulled up to the surface and re-stitched in it's original location.For a simple and illustrated explanation of tummy tuck and body contouring
procedures, watch my video.

You would benefit from a tummy tuck.  The type of tummy tuck is hard determine based on these 2 photos alone.  A tummy tuck with get rid of excess skin/stretch marks, tighten your abdominal muscles and narrow your waist. It is always best to consult with a board certified plastic surgeon.
