Injection breast augmentation involves using a specialized syringe to directly inject filler material into the spaces between breast tissue. Generally, this procedure has no significant impact on breast tissue. However, after pregnancy causes breast tissue proliferation, the filler material exerts pressure on the tissue. Particularly if complications like infection or rejection occur post-surgery, the filler can be extremely difficult to completely remove from the body. For this reason, doctors do not recommend injection breast augmentation for women who have not yet given birth.
Autologous fat transfer breast augmentation involves harvesting fat from the patient's own body, washing it with saline solution, and then injecting it into the breast tissue. Due to the complexity of the procedure and the tendency of fat tissue to be absorbed or liquefied, it may result in uneven breast size. For this reason, doctors also advise against this method for women who have not given birth.
Currently, the relatively safer option is implant-based breast augmentation. This involves making a small incision in a concealed location—such as the armpit, along the areola edge, or within the inframammary fold—to insert a specially designed breast implant beneath the original mammary gland tissue or deep to the pectoral muscle. While it causes some tissue disruption, implant-based augmentation leaves no visible scars post-surgery and is suitable for women who have not given birth.
