The Kylie Jenner big lip challenge has weird results
A lot of people are trying to copy Kylie Jenner's big pout by sucking on bottles to weird results.
Photos and videos are being uploaded of people trying the #kyliejennerchallenge to blow up their lips to huge proportions.
It works by putting lips over the airlock created in the opening of the bottle which increases blood flow to the lips and causes them to swell.
Some are regretting it though, because the suction can cause bruising.
A specialist suggests it is best to stick to make up to enhance your lips.
Dr Dendy Engelman, a dermatologic surgeon, told Seventeen.com: "The new trend in trying to DIY lip plumping is quite concerning.
"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."
