Kylie Jenner is one of the trend-setting young women on the planet.

With more than 69 million followers on Instagram (and counting!), successful clothing collaborations and a make-up line that sells out in minutes (or a single minute), Kylie's style is one that many of her adoring followers want to emulate. And while she's a mainstay on the best dressed lists for her fashion, one thing people can't get enough of is right on Kylie's face: her lips.

The fascination with Kylie's pout has grown into a phenomenon. Not only has her mouth been fodder for the gossip rags, but it even sparked the #KylieJennerChallenge, where teens stuck their mouths into a shot glass, sucked as hard as they could and swelled up their lips just so they could look a bit more like Kylie's own set.

Now that Kylie has admitted to using lip fillers to enhance her overdrawn lips and the popularity of her Kylie Cosmetics lip kits, we took a look back on her lip transformation.
