✓ Hard & Ultra-Hard: Find your perfect level
✓ The Rule: Extreme hardness = shorter flavor
Our JAWLINER Gums come in two hardness levels. While the Hard Gum (for beginners) delivers long-lasting flavor, the Ultra-Hard Gum (for experts) provides maximum resistance for quick results—but has almost no flavor. Chew them together to find the ultimate balance of flavor and intense jaw-training!
🔥 Gym Goer? Grab the Hard Gum as a Pre-Workout version with 40mg Caffeine. Clean energy for your heavy lifts and a bold workout for your jawline in one.
Our ancestors chewed tougher foods, developing broader, masculine jaws. Today's soft diets lead to narrower jaws and crooked teeth - just look at the rise in wisdom teeth problems.
The good news? You can reverse this. Dr. Mike Mew explains strengthening your jaw muscles with hard JAWLINER Gum helps you reclaim your natural, masculine profile. Start now and take back what modern diets took away.
Transform your profile. Your masseter muscle defines the look of your jawline. JAWLINER targets this exact muscle, turning a soft jaw into a chiseled edge. Every workout builds the bold, angular jawline that turns heads. Train more, see more - watch as your face becomes broader, sharper, and more attractive.
JAWLINER invented facial fitness chewing gum and has perfected its formula since 2018. With ultra-hard consistency, it delivers both powerful jaw exercise and refreshing taste.
German-engineered, JAWLINER replicates natural chewing resistance, targeting jaw and facial muscles to build your defined jawline with every chew.
Strong jaw muscles power more than your looks - they're essential for health. They promote proper oral posture (closed mouth, aligned teeth, correct tongue position), leading to optimal breathing and increased oxygen intake up to 20%.
The benefits extend throughout your body. Strong jaw muscles help prevent TMJ disorders while maintaining facial harmony, supporting your long-term health and wellness.

Oduvjek sam želio imat definiranu čeljust i masseter mišić te sam naručio Jawliner ,sad več par mjeseci žvačem ultra hard Gum i navikao sam se toliko da mi fali kad ne žvačem... Prije sam mislio stavit filer u čeljust ,a sad je moja čeljust toliko izgrađena da me i drugi pitaju kako.
Very nice for intensity, not for those who like gum flavor throughout the chewing, i'd suggest the normal ones and not these, good quality!
Pretty strong gum in 3 day im feeling the change
Besserer geschmack
j'ai reçu très vite mes gum Jawersize, sans frais de shipping supplémentaires (ce qui est très appréciable). Dès qu'elles sont entre les dents, on sent qu'elles donneront du travail aux masseters. Elles perdent leur goût assez vite, mais j'ai demandé l'avis d'un ami en week-end chez moi, il m'a répondu "c'est pas grave, même sans le goût ça occupe". J'en ai croqué que 2 pour le moment, je vais les emmener au bureau pour aider à la concentration
I really like the taste of these chewing gums; I use the ultra-hard cinnamon ones. I’ve seen some results, even if they’re minimal—I’ve included a before-and-after comparison after 3 months—but that’s also partly due to weight loss. In any case, I feel like my jawline stands out a little better; we’ll see how it looks in the long run.
Sans gout au bout de 2min et cher pour le peu de quantite l’impression de macher du latex
Honestly it works- I was a bit suss at first but my jaw looks chiselled like Donnie Draper lol. This is like my 3rd order wish they had this when I was younger!
Really nice product, taste is just byproduct but gum overall is ultra hard as described!
Very good and tasty gums
Amazing
Ultra Hard gum is great. Finally a gum that is hard enough. The ginger and lime flavor is the best from my experience.
funziona!!
I realy like the profuct especially the ultra hard one i can feel that its training my jaw. I definetly have developed a slightly more wide jaw. The only criticism i have is that the taste is only there for 3-4 minutes
It's a very hard gum and it builds the muscle in the face to get more attractive and to feel more confident . Even the Flavour is good.
Takes too long to become gum and the taste is nice but gives a horrible burning sensation in your throat
The Gum is great. Hard and insanely good.
De smager slet ikke af noget
Die Kaugummis eignen sich hervorragend für das Jawline-Training. Ich bin sehr zufrieden mit der Qualität und dem Effekt und kann sie definitiv weiterempfehlen.
I bought jawliner because I have a circular face and wanted a more defined jawline.I have been using the gym for around 3 days now and already see my jawline to get better
Die Produkte halten tatsächlich was sie versprechen. Ich nutze diese nun seit 2 Monaten und habe enorme Erfolge erzielt. Die Gesichtsform hat sich deutlich geändert. Positiv ist zu bewerten, dass durch den Muskelaufbau sich das Gesicht deutlich strafft. Ich bleibe aktiv dabei und kann Euch nur empfehlen.
Niceone
Saw significant progress in the masseter muscles.
Its tought enough. I made a mistake of choosing the ultra hard gum, when i never chewed a gum from your site but fortunately for me i already had a pretty strong jaw idk why but thw first day i chewed only 1 gum for 15 minutes ans had to take a few brakes but the very next day i chewed 2 at once and i managed to chew it for 50minutes straight I had a stopwatch in hand and I somehow took only 2,3 short brakes (2minutes or less) so the only thing i would advice to change is letting people know how to choose the right toughness of the gum. So they dont pick the hardest level of the gum the first time buying from you guys bcs I wasnt wxpecting it to be so tough but in the end its the right toughness level for me. Just for first time buyers make it clear to buy the lowest level or the level u guys advice to start off.
Je n’ai pas encore testé
Jawliner Passion Fruit Ice has a very fresh, good taste and results are visible even from the first weeks
top, sono parecchio dure e per l’allenamento della mascella sono perfette ora vediamo tra 2 mesi i risultati
really good
the best gum for training your masseter!
feels trained
I just chew one piece on my 15 minute journey to work and I feel like my mouth is getting a work , although it seems quite easy now
I've seen visible results using the gum and it gives the jaw a good workout that can be felt in the face muscles afterwards
I am very satisfied with all of the products and I my jawline is training everyday- as I look better from day to day I can only say, buy these Products
To be honest a bit more flavour would be nice
Hilft gut
Perfect
Les gums musclent la mâchoire efficacement.
ho già visto dei risultati ottimali dio boia ho la mascella che taglio la gente per strada
This is top quality product. Ordered three times since my first purchase!
Its very hard and you can chew for a long time, only downside is that the flavour loosens quickly.
Because it’s not candy—it’s high-performance jaw training equipment. While regular gum is 90% sugar and fillers, our Ultra-Hard Gum uses a high-density gumbase that requires 10x more raw material to achieve its extreme resistance. We use specialized heavy-duty manufacturing because standard machines break under the pressure of our formula. Plus, it’s reusable: One piece lasts for days, making the cost per workout actually cheaper than buying packs of normal gum constantly.
JAWLINER is engineered for consistency, whereas natural Mastic Gum is unpredictable. With JAWLINER, you get:
Superior Hygiene: No natural grit or impurities—just a clean, lab-tested training tool.
Yes, it is hygienic because it contains no sugar, meaning bacteria have no fuel to grow. To reuse it safely:
Pro Tip: Before your next session, hold it in your mouth for 2 minutes to warm it up. This prevents jaw strain from a "cold start."
To maintain the maximum hardness of our ultra-hard chewing gum, flavor is added only to the outer layer. This gives an intense burst of flavor at the start, but it fades quickly. Adding long-lasting flavor to the gumbase would compromise the gum’s hardness, making it softer and less effective for jaw training.
If you’re looking for a flavorful workout, try our medium-hard gum. It offers a pleasant taste and provides a light yet effective training experience.
You'll notice immediate results after each session - your jaw muscles will pump up, just like any muscle after a good workout.
For permanent muscle growth, expect visible changes within 2-4 weeks of consistent training.
Keep in mind: Results are most visible with lower body fat. For best results, combine with a healthy, protein-rich diet and active lifestyle. You'll look better and feel better!

This is a heavy-duty tool, similar to biting on a tough steak. For healthy teeth, it stimulates bone density and structural strength. However, if you have loose fillings, implants, or veneers, do not use the Ultra-Hard version. The extreme resistance is designed for building muscle, not for fragile dental work. Always listen to your body—if it hurts sharply, stop.
Losing body fat is the first step—fat loss makes your jawline automatically more visible. However, a visible jawline alone doesn’t make you more attractive. To achieve a wider, more masculine jawline, you need strong and well-developed jaw muscles.
Normal gum won’t help—it’s too soft to build muscle. That’s where our ultra-hard gum comes in. Specifically designed for jaw training, it provides the resistance needed to strengthen and grow your masseter muscles, transforming your jawline into a more defined and masculine shape.
In short, fat loss reveals your jawline, and our gum helps you sculpt it.
Welcome to the big leagues! If it feels too hard, your masseter muscles aren't conditioned yet. Use the "Mixing Method": Buy a pack of JAWLINER Medium-Hard Gum and chew it together with the Ultra-Hard piece. This lowers the resistance and adds flavor, helping you progressively build the bite force needed for the raw Ultra-Hard experience.
Yes, correcting facial asymmetry is a top use case. You can perform unilateral training by chewing specifically on your weaker/smaller side. This stimulates targeted muscle growth to balance your jawline. Check your progress weekly, and once symmetric, switch back to alternating sides (50/50).
