From the photos, this appears to be significant breast ptosis, likely grade 2 to grade 3, but the exact grade depends on where the nipple sits compared with the inframammary fold on an in-person exam. When the nipple is at or below the breast fold and the lower breast skin hangs significantly, the most effective procedure is usually a breast lift. A lift can raise the nipple-areola position, remove extra skin, reshape the breast, and improve the overall breast position. If the breasts are also too large or heavy, then a breast reduction with lift may be better than a lift alone. If the breasts feel deflated and you want more upper fullness, an implant or fat grafting may be discussed, but this depends on your goals and tissue quality. In your case, an anchor-pattern lift or reduction-lift would likely be more powerful than a small scar lift. A periareolar or donut lift would not be enough for this degree of sagging and could flatten the breast or stretch the areola. The best next step is an in-person consultation to assess nipple position, breast volume, skin quality, and whether you want to stay the same size, become smaller, or add fullness. That will determine whether the right plan is lift alone, reduction-lift, or lift with volume restoration.
