In most patients the part of the breast which stretches out most easily is the part around the nipple, so with or without implants, breasts still look like breasts with the passage of time. In some patients however, the part of the breast which stretches out most easily is the bottom of the breast, down below the nipple area. In such a patient, with or without an implant, the lower breast skin can bulge and sag downward, making the nipple (which does not descend,) appear too high. The larger the breast, the more weight, and the more this occurs with or without implants. In a predisposed patient, "bottoming-out" is equally likely with either over the muscle or under the muscle implants, because there is no pectoral muscle along the lower part of the breast. The only cure for this is a variation of mastopexy or breast lift.
