Notice that even in this smaller degree of breast ptosis, the nipples and areola have migrated to the lower pole of the breast. The mass of the breast has moved downward losing a youthful appearance.
Breast can naturally have a ptotic appearance.
Breasts enlarge during pregnancy as the glands prepare for milk production. As the glands return to their normal size, the breast's skin and suspension ligaments may stay stretched resulting in drooping. The same problem can happen after weight loss. By removing more skin above the areola, they can be moved back to a more natural position. Frequently a larger area of undermining is used to adjust the breast contour.
