Sounds like a revision procedure with Alloderm may help

Alloderm is a cadaveric (human) piece of skin that has been treated of all of its cells, leaving a matrix of collagen. It's used routinely in immediate breast reconstruction, but can also be used in revision procedures. The surgeon can use the Alloderm to create a sling for the implant to sit in, and can also position the Alloderm to correct and control your breast fold as well as the lateral (armpit side) of the breast mound.

You need to see a surgeon with a lot of experience with breast reconstruction because this procedure can be a little involved. With the right surgeon and surgical plan, you should experience an improvement in your appearance.

Good luck!
