Teens on social media have started a bizarre trend in which they try to emulate Kylie Jenner’s pout by giving themselves dangerous 'at home lip jobs' using bottles. Using the hashtag KylieJennerLipChallenge, teens are sharing their often terrifying pictures online, with many sporting bruised and swollen lips.

Kylie JennerKylie Jenner is known for her fuller pout.

For the ‘challenge’ teens share before and after shots of their lips in a bid to mimic the ‘Keeping Up With The Kardashian’s’ star’s pout. But the exact origin of the idea is unclear as Kylie achieves her pout using clever lipliner and not holding a bottle over her mouth.

To give themselves ‘bottle lips’ the teens hold the bottle (or a shot glass) over their mouths and then suck out all the air which causes the lips to swell and in some cases, blood vessels to burst.

The worrying trend has understandably caused alarm, with beauty experts speaking out against the bottle method. “The new trend in trying to DIY lip plumping is quite concerning," Dendy Engelman, a dermatologic surgeon told Seventeen mag.

"Not only can significant pain, swelling, and bruising result from these suction techniques, but there is potential risk for scarring and permanent disfigurement with repeated attempts.”

While Pordiis Kjartansdottir, a cosmetic surgeon told the Metro newspaper, “I can definitely say that this would be dangerous even just to try it, and especially somebody does it more than once.”

“The lips turn blue because blood fills up and they could easily become infected and lose all sensation It is a really dangerous stunt and I’d advise strongly against anybody trying it.”

So come on teens, put down the bottles and lets end this silliness and stop the #KylieJennerLipChallenge! We’re sure Kylie herself would agree that experimenting with make-up is a fun and safe way to try out new looks, but holding a bottle over your lips till your blood vessels burst is just plain insane. #StopTheKylieJennerLipChallenge!
