No one ever said looking good is easy. Just ask the hundreds of young fans who've taken the #KylieJennerLipChallenge since the hashtag started trending online earlier this week.

Here's how the attempt to replicate Kylie Jenner's iconic pout works: Place your lips inside a small glass jar -- like a shot glass -- and forcefully breathe in through your mouth. The glass works as a suction cup, causing swelling to the lips. And voilà! Just like that, you can have lips like the reality-TV teen.

Except -- as many of Kylie's copycats are realizing -- nothing worthwhile ever comes easy, which is why just a day after the Internet craze first took off, the hashtag #KylieJennerChallengeGoneWrong started trending online too.

The graphic fail posts depict a range of injuries -- from bruising and popped blood vessels to split lips and major traumas like deep gashes around the mouth. According to TMZ, some people have even been hospitalized.

It didn't take long for news of the dangerous trend to reach the "Keeping Up with the Kardashians" star, who was moved to publicly addressed fad on Tuesday, April 21, 2015.

"I'm not here to try & encourage people/young girls to look like me or to think this is the way they should look," she wrote on Twitter. "I want to encourage people/young girls like me to be YOURSELF & not be afraid to experiment w your look."

Kylie's luscious lips have long been a source of public interest. In late 2014, she faced rampant speculation that she'd had her pout surgically enhanced. "How long are we gonna talk about this lip thing? lmao," she tweeted at the time. "Let's get our lives together guys and talk about some important s---."

The reality-TV star maintains that she achieves her lip look with the help of makeup. In March 2015, she dished on the wonders of lip liner during an interview with Grazia U.K., saying that lip liner and contouring "definitely changed my life."
