What is causing the lower portion of my areola to dip in?

Hello,It is difficult to see what's concerning you with the provided photos. Your breasts are large and it is very early in the healing process.  Many thing will go on in the next 3 months that may or may not affect nipple position, shape, angulation, and size. You shouldn't really concern  yourself right now with much in that regard.Best of luck!

Hello
dear, thanks for your question and provided information as well.. I have to say that the areola position has to be performed on surgery, contact your surgeon and let him or her know about what you're feeling, this can be performed on another surgery as well if you're not happy with your first results.

I have
to say that you are still early on healing process, it is too soon to determine
how your results are going to be, per now, they look very nice and beautiful,
you can have one bigger than the other, it is normal and that can happen for
the first 3 months until your implants have settle in. I recommend you to wait
and keep using your post surgical bra, that will help you with the shape and
support. Hugs!

Thank you for the question and photo but it is hard to say what is going on from the photo alone so ask your surgeon as he knows what he did.  If you had a circumareola Mastopexy, you are feeling the area within the stitchDr Corbin

From the photos you have included, it's hard for me to see what you're talking about. It appears that you had a periareolar incision and that you are early in the postoperative phase. Because there's some tightness there from the sutures and not any tightness above any swelling of the underlying breast will not push the incision out as much as the surrounding breast and this may be what you're referring to as a dip. Let your plastic surgeon who knows you and what procedure they did counsel  you. Good luck and hope you have an uneventful recovery
