JAWLINER Hard chewing Gum, Jawline gum - Sugar Free Watermelon Gum - Jaw Exerciser - mastic gum for Mewing - 2x Harder Than Regular Chewing Gum 330 Grams(120 strips)

This stuff isn’t your average gum – it’s basically a mini gym session for your face. When you first bite down you realise just how much tougher it is than normal gum. It actually works your jaw muscles, which sounds ridiculous until you try it. The flavour holds up surprisingly well considering how dense it is. Most “fitness gums” taste like old rubber after two minutes, but this one stays decent. It’s weirdly satisfying because you can feel the resistance every chew, almost like jaw reps. I can’t claim I’ve suddenly developed a superhero jawline, but it definitely makes you more aware of your jaw muscles. It feels like a fun, gimmicky product that actually has some benefit.

My only downside, is that it's only the medium strength which is offered in this form. I'd love the harder options to be in a pocket packet form!

A couple of months ago I looked in the mirror and saw a saggy old face looking back. So I started on a jaw shaping and skin tightening regime to try to get back into shape. I read that chewing firm gum could help, so I decided to give it a go. Now, I am doing a range of new things to try to improve my skin and face shape, but I feel that this gum is part of what has helped me to regain some definition in my jaw and cheeks. The taste is pleasant mint (not strong) and lasts just about as long as the time I chew. Don’t overdo it to begin with, like I did, otherwise it might give you a jaw ache!

All the gum in every pack has dried out and is brittle. Completely ruined, probably due to heatwave. Can’t find a way to return.

Of course I was sceptical but progress speaks for itself, it really works! It’s not instant but over time it definitely defines your jawline.

Has very little in it but the flavour is nice

Works, however need to buy multiple packs.

Artificial sweeteners not listed in product description. It just says mint but on further research contains many nasty ingredients acselfumate etc.
