How long will it take my 350cc breast implants to drop? (Photo)

Dear Inclucas125,Dropping of implants is part of the
healing process and this occurs after the tissues surrounding the implants
slowly relax, allowing the implants to settle into their final position. It can
take about four to six months for the implant to drop down to their final
position.
I understand that you are worried about
your implants are not dropping as expected. However, you are still in the early
phase of the recovery period. Please do allow some time for the healing process
to occur. If after six months, you are not satisfied with the appearance of
your breast, you can visit your plastic surgeon and discuss your concerns.Daniel Barrett, MD, MHA, MS

Thank you for sharing your question and photograph and congratulations on your breast augmentation.  This soon out from surgery the swelling in your tissues is maintaining your implants high and flat against your chest but as this swelling resolves you should see a more natural shape and contour develop.  Though they will not get "bigger" you should see the lower portion fill your bra cup more and more.  Hang in there, most of these changes take place 6-8 weeks after surgery.
