Lifestyle | Wellness It’s not been long since the word mewing made its way into the popular conscience. Fun to say, but less comfortable in practice: it’s the act of placing your tongue on the roof of your mouth to mime a stronger jawline. And it was suddenly being seen in classrooms all over London , much to the lament of teachers.

And the pursuit of a sculpted lower face now seems to have spawned another more involved ritual: chewing very tough, ‘facial fitness’ or ‘training’ gum. On TikTok , mewers and fans of the ‘towel technique’ (yes, literally biting down on a towel to train your jaw) are also shouting out the merits of these premium priced gums such as Jawliner to give them a visage to rival Timothée Chalamet ’s, or indeed Kylie Jenner ’s — though it’s mostly male faces you’ll see. They work out at around £0.

38 per piece versus a regular gum at around £0.05 per piece. Spend a few minutes in the merky world of #JawlineTok and you’ll soon be served a video of an American bro or an English guy in scrubs heralding the gum as helping you to look more chiselled if you masticate on it for around 15 minutes a day for an elongated period.

Many of the videos claim to show jaw transformations from using the gum for as little as a month and some have in excess of 2.5 million views.
