Suckers copy reality star look

Kylie Jenner, inspiration of the "Kylie Jenner Challenge" - where a person places their lips in a shot glass and sucks until they are swollen.

Kiwi women have been sucked in by a painful international beauty craze which purports to give you fuller lips.

Pictures of local ladies trying the "Kylie Jenner Challenge" - where a person places their lips in a shot glass and sucks until they are swollen - have joined the thousands of images from all over the world appearing on social media this week.

Some New Zealand women say they were left with large bruises, with one local DJ warning others off trying it because her face hurt.

Internationally, women have suffered cracked and bleeding lips, and several have been cut when the glasses used for suction exploded.

Tauranga blogger Holly-May Neho tried the "challenge" - which was sparked by those trying to imitate reality star Jenner's pouty look - and said it was ridiculous.

"I did it for a joke," she said. "My lips were enormous."

She said she wouldn't recommend it.

"If young girls are gonna do it and hurt themselves then that's a risk they are taking."

Lily Taurau, a presenter on radio station Mai FM, posted a video of her inflating her lips.

"Oh my god it's all blue," her colleague says when she takes the cup off her face.

"Look at the ring around your face."

"It hurts," Taurau said. "They're tingling." She looked at the camera and said, "don't do it, I don't recommend it ... ow."

On Facebook, several listeners replied to the video post with their experiences. One mother said her daughter was dared to try it and then had to have two days off school. "Lesson learnt," she wrote.

An Auckland doctor who does cosmetic surgery, Ellen Selkon, from Clinic 42, said the practice was "full of possible complications".

"I don't think it's a good idea at all," she said. "It could end in permanent damage, like scarring."

There were plenty of other alternatives if women wanted fuller lips, such as fillers, Dr Selkon said.

She said the clinic was yet to see anyone with injuries from the challenge, but it was likely just a matter of time. Auckland District Health Board reported no cases as yet.
