Thank you for your question. I agree that you should wait 6 months before attempting a third revision. If you do go forward with another revision ask yoursurgeon about the use of AlloDerm and some muscular placement of your implant. AlloDerm as a biologic membrane that can add support to the lower pole of your breast.
You are in a very early period after your breast augmentation revision. Typically things tend to get better with a little bit of time. Second I would wait at least six months before going back for any type of revision. The capsule, or internal scar tissue can be used to shape and hold the breast in proper position, but you have to give this time to form.
There are other things that can be done to help hold the shape of the breast internally if you need further revisions to improve your breasts.
I think at this point, you need to allow the breasts to heal. Give it some more time and be patient. Good luck with your results.
