Over the years, factors such as pregnancy, nursing, and the force of gravity take their toll on a woman's breasts. As the skin loses its elasticity, the breasts often lose their shape and firmness and begin to sag. Breastlift, or mastopexy, is a surgical procedure to raise and reshape the breasts with adding an implant for fullness. A mastopexy can also reduce the size of the areola, the darker skin surrounding the nipple.
