What is Jawzrsize?

a jawzrsize device

Jawzrsize is an exercise device designed to workout to your jaw. Essentially, it's a hollow, ball-shaped piece of rubber.

   It's got 2 silicon moulds (one the top and bottom) that are formed to the shape of your own bite. It makes it more comfortable to use.

   The idea is to provide much more resistance than food or chewing gum, to workout the muscles of the face, neck and jawline.

   The main muscle it aims to target is the masseter of the jaw – hence why it's called JAWzrsize.

   Jawzrsize was created in 2016 by an American guy called Brandon Harris. It became popular quickly because it was the first device marketed specifically as a way to improve your jawline.

   Since then, dozens of new tools have been created and lots of innovation in the space. Jawzrsize doesn't seem to have kept up. Read more in my Jawzrsize Review.




  • 👋 Most Well-Known Jaw Exerciser: Jawzrsize were one of the first on the market, their branding is recognizable
  • 👻 They Won't Scam You: Jawzrsize is a legitimate company and if you ask for a refund, you'll get it.
  • 🇺🇸 Made in USAmost jawline exercisers are made in China or Pakistan. That doesn't mean the quality is worse, but you don't know about the healthy and safety conditions of the workers.
  • 🛒 Easily Available in the US  it's on Amazon, so you can buy it and get it the next day in most places. They ship to US, Canadian, Europe and Australia. So it's available... but as we discussed before- it's expensive
  • 📞 Decent Customer Service  I personally did not get a response to my customer support inquiry. However, from reading reviews and comments, it's obvious that Jawzrsize offers above average customer service
  • 👷‍♂️ Made from Safe Materials  I'm listing it as a pro for Jawzrsize, because many other cheap jawline devices are made from harmful materials. But basic health and safety is the bare minimum. Jawzrsize meets all the requirements



  • 🌝 Leads to a Round Face – it stimulates and grows the temporalis muscle WAY too much. This can have a severely negative effect on your facial aesthetics by widening the top half of your head- particularly above your ears
  • 🦴 Harmful for the Jaw Joint – the Jawzrsize device is too large and the jaw was not designed to apply high levels of force when it is so far open. Here I come TMJ, jaw joint arthritis, stiffness and clicking!
    • 🚨 Breaks Easily  the moulds that your teeth bite down into break quite quickly. Your incisor teeth are made for piercing after all. You either pay to replace them... or you continue using it without them and place even higher pressure on your front teeth
    • 🦷 Damages Your Teeth – this device applies all the pressure to your front incisor teeth. These teeth are made for piercing and tearing, NOT for grinding and applying high force like the molar teeth are. I'm surprised their aren't more stories of people damaging their teeth with Jawzrsize
    • 🤮 Produces Insane Amount of Saliva  you need to keep a bowl underneath your chin to catch all the liquid that pours out of your mouth
    • 🤡 Looks Like a BDSM Ball Gag  you can't use Jawzrsize in public... It looks too weird and it makes you gag





    What is Jawliner Gum?

    Chewing a hard gum is the simplest way to improve your jawline.

       But Mastic gum isn't for everyone. Jawliner Gum is an alternative that is sweet, mint-flavored and just as hard. 

    Jawliner Gum is a top-seller on Amazon


    ✅ PROS

    • 🔥 It's INSANELY Effective: Jawliner Gum has hundreds of reviews and before and after transformation photos to prove that it sharpens your jawline. This is the most important criteria for picking a jawline exerciser. There's no doubt about Jawliner Gum's effectiveness
    • 💪 Builds the Right Muscle: you're trying to improve your jawline and your appearance... the goal isn't to just build muscle in your face, right? You have to build muscle in the right place. The masseter muscle, particularly the lower portion, is the part you want to grow. Other jawline exercisers grow the wrong muscles, which will make your face rounder. More on that later.
    • 🎖 FDA Approved: this gum have been tested and approved by the Food & Drug Administration as well as by the PICA institute of Berlin
    • 👨‍🎓 You Can Workout Anywhere, Anytime: you can chew gum when you're working, studying, driving or working out. It's easy to train and nobody even knows you're doing it. Some of the other jaw exercisers aren't as discrete, and frankly, they'd be embarrassing to pull out in front of other people
      • 👌 Every Piece is the Same – with mastic gum, each piece is slightly different. Some might be extremely hard, others might be soft. That's because it's a 100% natural product. Each piece of Jawliner Gum is the exact same. Same hardness, same taste. You know exactly what you're getting
      • 🦴 Zero Joint Damage: chewing a small hard piece of gum is a natural movement and texture for your jaw, teeth and gums. You won't stress any muscles, joints or get TMJ. I can't say the same for some of the other jawline exercisers
      • 🍃 Mint-Flavored – Jawliner Gum is just like regular chewing gum, but much harder. Not everyone likes the cedar flavor of Mastic gum. Jawliner Gum is a great alternative
      • 🦷 Not As Harsh on Teeth and Gums – Mastic can be quite hard on your mouth if you have sensitive teeth and gums. Try Jawliner Gum for a softer experience
        • ≣ Every Piece is the Same – Mastic is a natural product picked from a tree – the pieces aren't the same. Because Jawliner Gum is manufactured, it can be made in uniform pieces with the exact same hardness and flavor
        • 🤑 Cheap – because it can be mass-produced, Jawliner Gum is much cheaper than Mastic Gum
        • 🟧 It's Now Available on Amazon: you can it from Amazon, though it is often out-of-stock and you may have to wait to get some
        • 😃 A Sharper Jawline... Or It's FREE: either you'll see an improvement to your jawline or you'll get your money back. The same goes for all STEEL products


        ❌ CONS

        • 📋 It Runs Out: once you chew through your pack, you'll have to order more
        • 🤤 Taste Doesn't Last Long: most chewing gums lose their taste after a while, Jawliner Gum is no different

           But health experts, and jawline experts, would agree with my analysis that Jawliner Gum is more effective for safely building your jaw muscles than Jawzrsize is 👇
