While some changes in breast shape and size can be seen immediately after surgery, the final results of breast augmentation typically take several months to fully develop. This is because swelling needs to subside, and the implants must settle into their final position. It’s common for patients to notice ongoing changes over the first six months as their body adjusts to the new implants. Patience is key during this period, and it's important to follow up with your surgeon to monitor your progress.
