Celebrities are often inspiration for the latest fashion or cosmetic trend, but when should fanatics draw the line between a matching haircut and an extreme body modification? Although reality star Kylie Jenner insists that she has not undergone any plastic surgery, fans have noticed a recent change in the size of Jenner’s lips. On Sunday, #KylieJennerChallenge started trending on Twitter, and the results could prove to be the most nonsensical celebrity beauty trend to date.

In hopes of matching Jenner’s pouty lips, teenagers have started performing DIY lip enhancements by sucking on a shot glass to purposefully swell up their kisser. Before and after pictures posted to social media show the disastrous results which have parents, doctors, and fellow teens asking: why? These teens may think a little swelling in the lips is nothing to worry about, but health care professionals warn against this senseless beauty practice.

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