Results of suctioning your lips to shot glasses include bruising and bleeding. Twitter Kylie Jenner has always said her majorly plumped-up lips are the result of makeup rather than cosmetic surgery.

Now teenagers and fans of the youngest daughter of Kris and Bruce Jenner are mimicking her look by suctioning their lips with shot glasses and posting the results on social media.

This DIY method appears to be even more dangerous than collagen injections, with hundreds of Instagram photos tagged #KylieJennerChallenge boasting bruises, bleeding, and "lip hickeys."

Forget trying the challenge yourself; looking at the photos is painful enough.

Here's what participants of the #KylieJennerChallenge are doing: First, they're placing a shot glass or similar small cup around their lips. They then inhale for a few seconds to create a suction effect. After a few minutes of holding their lips in the airtight shot glass, their inflated lips are revealed:

The effect of plump lips is temporary — in fact, the bruising and "lip hickeys" that result probably last longer. For every #KylieJennerChallenge reveal, there is another tweet or Instagram post showing the stunt's disastrous results after the swelling goes down:

These photos aren't even the worst of the bunch. Many we saw were even more graphic. (Click at your own risk.)

The hashtag has become so popular on both Twitter and Instagram that it is impossible to see where it originated, but this April 18 tutorial from YouTube user Brendan Jordan demonstrating the shot-glass trick has almost 313,000 views and appears to be one of the first sources for the current popularity of the #KylieJennerChallenge.

Now, many tweets and photos using the hashtag are imploring others not to take part in the challenge.

One thing's for sure, though: This is one DIY beauty trend that the Kardashians and Jenners aren't responsible for promoting.

The famous family has often turned to social media to promote their favorite beauty tricks. Contouring and waist-training shot to popularity thanks to the Kardashians' influence.

In an attempt at transparency, Kim Kardashian and Kris Jenner have gotten Botox and a facelift, respectively, on their hit E show. Also, eldest daughter Kourtney Kardashian admitted to having breast implants in an early season. Still, many speculate that more treatments and procedures are happening when the cameras aren't around.

The youngest of the brood, Kylie Jenner, denied having had lip injections, saying instead that she used lipstick and lipliner to enlarge the appearance of her lips.

"You guys have watched me grow up since I was 9," she told Cosmopolitan in January. "My face is going to get different. Now, I know how to do my makeup, contour and everything. I'm not against surgery. I'd never say no, but I don't desire it right now."

Her DIY approach might be the inspiration behind the shot-glass stunt, but there's no way Kylie's achieving her perfect pout by sticking a cup on her face.
