Since the fountain of youth is a myth perpetrated by that silly fictional adventurer Ponce de León, Hollywood celebrities must rely on plastic surgeons to help them keep their youthful appearances. Or at least try to.

From aging celebs who become walking billboards for what not to do to your face to young actresses who think their bodies could be even better, Hollywood is full of stars willing to go under the knife. Sometimes it works out for the best, but more often than not it causes people in the street to run away screaming, "Dear God, what is that thing?"

Regardless, it's a Hollywood tradition that isn't going away anytime soon. We apologize in advance for any faces you won't be able to unsee or noses that were ruined in the process of achieving monster-like "perfection."
