Cosmetic fillers are substances that smooth wrinkles and folds by bulking up the tissue underneath. Doctors inject them directly into problem areas. Collagen is the oldest and best-known cosmetic filler.

Fat transfer breast augmentation has a few important limitations. First, fat transfer is typically limited to approximately one cup size increase in breast size. Second, the transferred fat may be absorbed again by the body. Third, it is more expensive because of the extra time involved in harvesting and processing donor fat as well as possible need for a special vacuum bra device. This option is best reserved for women who desire a modest increase in size without using an implant.
