Do breast implants have an expiration date once they have been placed, meaning is there a fixed time when they need to be changed or replaced?
No, if your body shape is stable and there are no problems with the implants, there is no fixed time frame for when they need to be replaced. However, if your body changes with age or pregnancy, or your tastes change, or you develop problems with the implants they might have to be changed at some point in the future.
