How long does a Mastopexy last?

Any surgery can not be considered permanent as far as aging, gravity and your personal bra-wearing habits go.  Gravity and age will prevail and you will sag - period. Although we can attempt to slow its process by maintenance and healthy eating.  Whatever the situation, a woman's breast tissue, in 95% of cases, will sag eventually.  Regardless of having had Mastopexy, a breast will sag again.  It may be years from now, but you may need an additional Mastopexy depending on your habits of bra wearing, this may be slower.  It is supposed that a breast may sag again after 15 years with part time bra wearing, less than half that if a bra is hardly worn.  If you have very thin skin, even less.  Be safe and wear a bra.
