How long do the results last?
There is no one answer for how long implants last. It may be between 6-8 years or as long as 15 years, but predictions in individual cases are nearly impossible. All manufacturers in the European Union market at this point (2007) grant an unlimited durability of their implants, a life-long guarantee as far as material is concerned.
Keep in mind that larger breasts sag faster than smaller breasts, and augmented breasts do this as well. Gravity, unfortunately has no exceptions. Ten or twenty years after surgery, successful augmentation patients will still look far improved over those who haven't had surgery. If new implants are necessary in several years or if an additional breast lift is advisable can be decided at that point in time.
