MADE OF 100% HIGH-QUALITY FOOD-GRADE SILICONE – Other jawzrsizers on the market may contain harmful byproducts and fillers. SIGNATURE jawline exerciser kit uses non-toxic, BPA-free, hypoallergenic silicone. Its resilient, non-porous surface is indisputably safe AND durable for high-intensity chewing. Mechanically engineered to cleverly stimulate 50+ face, jaw, cheek, and neck muscles as a jaw exerciser for men, jaw shaper for women, or double chin remover.
ERGONOMICALLY DESIGNED TO PROTECT FRONT TEETH AND GUMS – SIGNATURE face exerciser for women fits your jaw as you chew and most importantly – ONLY engages the molars. Many jaw strengtheners for men (such as the jaw workout ball) overwork the front teeth, causing more harm. They damage them AND their gums because by nature, front teeth are made to cut or bite, not chomp heavy loads. Highly-protective of your molars, our face shaper for jawline won’t hurt incisors nor cause oral bleedings. Phew!
GET REAL RESULTS IN A MONTH – Just pop the 2 SIGNATURE face slimmer exercise mouthpieces in your mouth and chew them with your molars. Exercise 10-20 minutes a day, every other day for a month to witness picture-perfect muscle building, jawline shaping, jaw tightening and lifting, naturally, without painful interventions. Non-intrusive. Discreet yet powerful. Ridiculously easy to incorporate in the busiest daily routine. Just pick the right level of resistance for your jawline, and go for it!

Material: Silicone (food grade)
Weight: 20g/pair 2Pcs
Size: 3*1.5/cm
Packing: opp bag

High quality material. The exerciser is made of free food grade silicone. Non-toxic silica gel does not contain any chemical fillers or by-products, so you can chew with confidence. It is made of the same material as the baby pacifier.
Exquisite packaging. Each package comes with 2 pieces and a beautiful storage box.
Humanized design. The exercise film is designed to use molars for training, which is safer and more effective. Different from other types of exercisers, using front teeth (incisions) for training, this exerciser may damage the front teeth and gums.
Multiple benefits. Chewing has been proven to reduce cravings, leading to more weight loss, getting rid of double chin and loose facial muscles. The jaw trainer strengthens your jaw and face to help tighten, jagged and slim your face, making you look younger.
No more reason. There are no more excuses: “I don’t have a lot of money”, “I don’t have time to go to the gym”. Whether you are at work, fitness, at home or on the road, you can use the double chin reducer anywhere.

Jacked Jaw is the real deal!! I had been looking for a jaw exerciser on the market for some time but most products didn’t fit what I was looking for. Jacked Jaw is the only product I saw that looked like a professional brand and like it was the real deal. There are easy instructions on how to use it included in the packaging. I got the red (advanced) jacked jaw since I wanted to push myself. I have been using it for a few days and while my jaw is sore I already feel the results! Can’t wait to see how I look in a couple weeks. I definitely will recommend it to my friends and I recommend it for anyone looking for a jaw exerciser!!

OMG this is effective. I noticed a more defined jaw line within days. You can really feel this working out the muscles. This feels like a life changer for aesthetic confidence in my facial features.

It’s a really good fit and I’m sure it’ll fit everyone’s mouth. I have seen improvement in the amount of reps I can do with it and feel that it is improving my jaw. Everyone should try this out.

So far I love it! I work from home on a computer all day so it’s easy to use and helps time pass. It also makes my jar tired so helps me from over eating and constant snacking while sitting at a computer for 8 hours a day. Once I master this one I will be getting the next step for sure!!! Hope this helps my double chin go away soon. I’m sure the lack of snacking will help with that as well.

It definitely works, but it hurts my front two teeth which are what is used to bite down on it. I make sure to only train it every other day or every two days, I can see how it causes some people to have pain if they have Tmj. There’s a significant difference in my bite force when I eat food. I had to open a wine cork with my teeth and it was almost too easy. I expected to be using more force because my cousin couldn’t open it and gave it to me to open. I felt like I had a significant difference in bite strength. I just don’t know how the more advanced and harder jacked jaws will be on my front teeth. I’ll keep this updated.

These are supposed to help train for muslces in your face and help you get rid of that double chin and improve your face to improve your smile. you can use them anyway . They are small discreet and you can multitask while using them. They are made of silicone and safe to put in your mouth.

So I started with the yellow and I think that's the perfect place e to start. Yes, it's difficult to do it for more than a minute or two but it works the muscles well and it's satisfying. Yes the front two teeth can hurt a little but I was able to work around that by holding it a particular way in my mouth. Even if not to get a jacked jawline, it just feels great after working out your jaw muscles.

This is an awesome product!!! I honestly feel like it's changing my life. There are not many products like this out there and the ones that are are too expensive. This one is just right for the price. I've only been using it for a couple weeks and I swear I've been getting more compliments from the ladies when I go out. My girlfriend gets so jealous and she can't stop touching my face, she says I look like a Greek God!! My jaw has never been so defined. Would recommend to anyone looking to improve their looks, this is a must!

I was worried that this would be too hard or too big to fit my mouth according to some reviews. It’s not, as for it being hard, well it is a little tougher than I thought it would be but I guess that’s the point. I tried once and could barely do 15 reps. I’m sure will get easier in time and then have to move up to the next level. So far I feel I made the correct choice ordering Jacked Jaw. Time will tell

I purchased the easy version of this product and even that does a great job exercising my jaw. The shape fits my relatively small mouth well, and there are no issues with it tasting bad and or being hard to wash. I enjoy using this jaw exerciser whenever I’m watching a tv show or otherwise just chilling and it’s a great way to easily tone your jawline while relaxing. I’d highly recommend this product to anyone looking for a jaw exerciser, or anyone who’s just looking for something new to try.

People forget that your face has muscles just like other parts of your body which you can exercise to slim down. After using this exerciser a few times (following the instruction), I can feel the jaw muscles get tired like any other muscle. Be very careful not to overdue the workout as you do not want cramping with your jaw muscles/face. It is not a pleasant experience to have lockjaw and can be frightening. I have used a similar product before. This jaw exerciser is more stiff than that one requiring more effort and less repetitions. Just be patient and don’t overdo it and you will be on your way to stronger and slimmer jaw.
