Parents: Recently there has been a lot of conversation around the ‪#‎KylieJennerChallenge‬ —artificially plumping one’s lips to look more like the 17-year-old reality TV star, by sucking a shot glass.

We asked Patrick Byrne, a facial plastic and reconstructive surgeon at Johns Hopkins, about his thoughts on the “challenge.”

His response:

“I would not recommend that anyone attempt to perform this maneuver. This ‘challenge’ involves the creation of negative pressure with subsequent trauma and venous engorgement of the lips. This could potentially cause significant damage and deformity to the lips and the surrounding skin, some of which could persist for quite some time. Put another way: Don’t do it!”
