Why are my nipples changing after breast augmentation when I’m a year out? (Photo)

Dear girl876,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Your large implants have stretched your own breast tissue and have stretched your areolae. This is normal. However, your implants are a bit too large and heavy for your tissue and are beginning to bottom out from the weight. do wear a good supporting bra. If you decide to have a revision, so smaller, have the inferior pockets tightened, and consider getting mesh for extra support.

Your outcome looks fairly typical for a breast augmentation with the stated implants.
It would be helpful. If you could describe what concerns you have in better detail.
Patients should expect some differences in sensation after having cosmetic surgery.
Your breast are slightly divergent, and this is usually amplified with implant augmentation because of projection.
Best,
