It is possible to combine breast augmentation with mastopexy  in a procedure called Augmentation Mastopexy.
Implants can restore lost breast volume, but they cannot defy gravity. If a moderate/severe amount of sagging exists, adding an implant is unlikely to produce an aesthetically pleasing outcome.
A breast lift can correct sagging and raise the nipple. Combining the two procedures can ensure that any breast size increase looks natural with your proportions and is aesthetically pleasing in and out of clothing.
