By inserting breast implants, does that naturally lift up skin under your breasts? Upper ribs?

Simply placing larger implants in a patient who needs a breast lift will not accomplish much except to make the breasts larger.  The implants do not raise the tissues at all.  They can give the perception that the breast is raised for a while since it is fuller, but over time the added size simply pulls the breast down to where it sits already.  Consequently, you have a larger breast that still sits lower.  The best thing to do is to have a few consultations with board certified plastic surgeons and see what is recommended.  I hope this helps.

     Breast implants will lift breast tissue but will not cause tissues on the upper abdomen to be lifted in a lasting manner.  There may be some initial tightening but this will not last.  Sorry, but breast implants are not a solution for loose upper abdomen skin.
