A 16-year-old boy is warning others not to attempt the Kylie Jenner challenge after his own disastrous attempt at inflaming up his lips using a glass.

Schoolboy Kevin Coulton spoke out about the dangers of the gruesome internet fad after it left his face bruised and swollen.

He posted a picture of his damaged face on Facebook, with the line: “Don’t suck into a glass.”

The painful craze has seen young people post videos of themselves inflaming their lips by using a glass and sucking the air out, creating a vacuum, until their pout puffs up - in the hope of emulating American reality star Kylie Jenner’s bee-stung pout.

Kevin is one of the latest victims of the bizarre experiment and was left in agony with a severely damaged set of lips.

The student, who attends Cardinal Langley RC High School in Middleton, says the trend is all the rage amongst teens, but is warning others not to follow in his footsteps.

He told the M.E.N.: “It’s a bit stupid. Everyone’s doing it and I just thought I would too. There wasn’t really a reason.

“It really did hurt, and it went all purple and bruised straight away. It hasn’t gone down three days later. My parents were shocked.

“I did it with a glass. A lot of people say it should be done with a shot glass to do it properly. Everyone in school is doing it. But I want to tell people not to. It hurts and the bruising takes ages to go down.”

A Twitter search of #KylieJennerChallengeGoneWrong brings up hundreds of images of teens posting the results of their attempts at the disturbing social media trend.

Most selfies circulating on social media sites depict bleeding, swelling, bruising ... and a lot of dribble.

Countless teens have been sharing their disturbing results, with most regretting it. Some say the results last for hours, if not days.

In response to the phenomenon - although not directly mentioning the challenge – 17-year-old Kardashian member Jenner posted that people shouldn’t ‘be afraid’ of experimenting with their look.

Critics say the shocking #KylieJennerChallenge hashtag is encouraging teens to compete to share their ‘enlarged’ pout, ignoring the potentially damaging effects.

Youngsters are being warned that the pursuit of luscious lips can leave them with lasting damage. Experts say the ‘vessel engorgement’ sets off an inflammatory cascade of chemicals, which flood into soft tissue and cause swelling.

If people suck hard enough, they can break blood vessels, which causes bruising.
