Breast lift surgery helps correct excessive breast sagging to give the breasts a more youthful appearance. Once the breasts have begun to sag, often after pregnancy or fluctuations in body weight, only surgery can restore them to a perky position. This procedure elevates the nipple and areola while reshaping and tightening the breast. A breast implant does not lift a sagging breast, it just makes it a bigger version of the shape it already has.
