Harry Potter: 10 Magical Potions With CRAZY Effects
6. Ageing Potion
Effect: Temporarily makes the consumer older.
Seen In: Harry Potter and the Goblet of Fire (novel/film), LEGO Harry Potter, Harry Potter: Hogwarts Mystery.
A potion that we've actually seen in use on the big screen, the Ageing Potion was used by Fred and George Weasley in Harry Potter and the Goblet of Fire, in an attempt to bypass the Age Line that Dumbledore had placed around the titular Goblet.
This barrier was intended to stop underage pupils from "applying" for the Triwizard Tournament, but - cheeky and disobedient as they are - the Weasley twins thought that they could simply take an Ageing Potion and trick Dumbledore's security system.
They were wrong of course - but that doesn't mean the potion is ineffective. It does work, it's just that, in this case, Dumbledore was smarter than two teenage boys.
While the Ageing Potion doesn't seem to have too many desirable uses on the surface (honestly, who wants to make themselves older?), the fact that it can adjust the user's identity at such a deep, deep level is a remarkable effect, and it's odd that we didn't see this one a lot more across the Potter books.
