The practice was slammed for being dangerous and ridiculous - with the potential for permanent nerve damage.
Thankfully, some teenagers have started to hit back, starting the hashtag #NoKylieJennerChallenge which celebrates being au naturale.
Whether sporting a plump or small pout, Instagram and Twitter users posted their selfies with the hashtag to encourage others not to feel the need to mess around with their faces.
Kylie Jenner, 17, finally admitted to having lip fillers this month after months of speculation. She had previously avoided questions about her plumper pout, or maintained that she was just ‘very good with makeup.’
And while some may still turn to surgery to boost their lip size, we think it’s great that so many teens have the confidence to feel good in their own skin.
