From the photos, you appear to have significant breast ptosis, meaning the nipple and breast tissue sit low. In this situation, a breast lift is usually the main procedure needed to raise the nipple position, remove extra skin, and reshape the breast. Auto-augmentation means using your own breast tissue during the lift to create more upper fullness without an implant. This can be a good option if you do not want to be smaller and you already have enough breast volume. It can improve shape, but it usually does not create the same long-term upper-pole fullness as an implant. If you want to keep your current size, a lift with auto-augmentation may be a very reasonable choice. If you want more roundness or upper fullness than your own tissue can provide, then a small implant with a lift may be discussed. However, implants add weight and can increase the chance of future sagging, especially if the skin is already stretched. A lift alone may make you look slightly smaller because loose skin is removed and the breast is reshaped, but it does not have to be a true reduction unless you want less volume. Your surgeon can plan the lift to preserve as much tissue as safely possible. My advice would be to ask your surgeon whether your goal is best met with a lift alone, lift with auto-augmentation, or lift with a small implant. Based on your wish not to go down in size, auto-augmentation is worth discussing, but the final choice depends on how much upper fullness you expect.
