Begin Your Transformation

◽️Jawline gum (mastic gum) is up to 10x more resistant when compared to normal chewing gum. The gum crystals are harvested from our facilities in Chios, Greece.

◽️Our included jawline exercise program will challenge 8 total muscles in the jaw and neck with short 10 minute daily workouts.  They help create that "hollow cheek" look as well.

◽️Your jaw WILL be sore, however, even after the first day (the easiest day in terms of reps).  We highly recommend in our jawline exercise program to alternate days on/off of exercise.  You need to give the muscle time to rest, just like any other muscle!


But that's a small price to pay for a sharp jawline!

◽️Our customers were happy to see a noticeable transformation, giving them a sharper, more defined jawline within the first few workouts.  Many customers have seen a tightening of skin in the cheeks and jaw as well.

⭐️Go from chubby cheeks to Greek God⭐️


Our Collagen Gummies are a perfect supplement to the jawline exercise program. They will help reduce fine lines and wrinkles*, moisturize/tighten skin, provide anti-aging properties* and are Non-GMO. Your collagen production declines as you get older which causes your skin to wrinkle and sag, so we jam packed collagen and biotin into our delicious berry🍒 flavored gummies to keep your skin looking awesome!

Combine the crystals and gummies for the ultimate 1-2 punch with our discounted monthly combo pack!

◻️How It Works◻️

  ◽️Our secret sauce is in the main ingredient, Mastic crystals.  They can be grown only in Greece, and have been commonly harvested and sun dried into a rough chew, dating back over 2500 years. Each tree takes 7 years to yield a few pounds of mastic, so the substance is very scarce.

  ◽️Mastic is up to 10x tougher than your average chewing gum.  (Google- Mastic Jawline)  It has also been proven to have a positive effect on the digestive system as well!  Feel free to swallow your saliva while chewing.

  ◽️We provide a strict workout regimen to strengthen and grow the masseter, temporalis and pterygoid muscles in the jaw.  

  **It is recommended in the included exercise program to take a day off in between workouts in order to give the aforementioned muscles a chance to rest and grow, just like any other muscle.  It is not uncommon to have difficulty chewing normal food for the first day or two, as these muscles will be extremely sore and will need some time to heal and acclimate.

◽️Couple your workouts with our gummies for the ultimate 1-2 punch!!

1)  What do the crystals taste like?

The crystals are organic and completely natural with zero sugar.  There is not much of a flavor except maybe a hint of chalky pine/cedar at first.

2) Can’t I just chew gum? 
Chewing gum is like running a mile.  Our crystals are like running a mile with a 100 pound weighted vest.  Just like training any other muscle, resistance matters!

3) What makes these crystals so special? 

Looking at the individual pieces, they are semi-hard at first.  You need to chew into it for a few seconds to turn it into a rubbery texture.  This chew is up to 10x more resistant than regular chewing gum.  It is not recommended to chew for extended periods of time as the jaw will get tired fairly quickly.

4) How long should I chew for?

The package will outline our recommended workout routine.  Results are typical within a week (you will feel the burn after day one, which is why we recommend chewing at night to give your jaw a chance to recover).  One month of diligent exercise will yield great results.  Additional exercise, just like any other muscle, will help to maintain a chiseled jawline year round.

5)  What am I actually strengthening?

You are exercising your masseter, temporalis and pterygoideus medialis muscles.  Growing these will leave you with a more profound jaw.

6)  Why the jaw?

Beauty is in the eye of the beholder.  With that being said, take a look at any movie star/model/supermodel.  It is not a coincidence that they have the most profound jawlines- male and female alike.  A strong jaw line is attractive, and growing yours can yield a nice confidence boost.

7)  What if I have TMJ?

Please restrain from using this product if you have TMJ or any other jaw/joint issues and speak to a doctor first.

8)  Can I use this if I have braces?

Please speak to your orthodontist before using this product.  Like gum, this product can stick to braces and any dental work. 

9) The jaw isn't a muscle, it is bone

While we cannot change our bone structure without some crazy surgical procedure, there are 3 main muscles in the jaw we focus on exercising to define the tone and tightness of the jaw and side profile. These 3 muscles are the masseter, temporalis and pterygoid.

Workout Program


-Place 1 thumbnail sized crystal in your mouth (or 2-3 small crystals) and chew it until your saliva molds it into a rubbery substance. The initial chalky flavor is the natural mastic substance and you CAN swallow your saliva. Studies show that mastic actually contains healthy/beneficial properties in digestion. If the first piece is too soft, add another small piece to toughen it up. Perform reps with the crystal in the back left of your mouth. Immediately alternate and do the allotted reps on the right side. This is 1 "set". Each "rep" should include a full range of motion with the jaw opening wide and closing. 30 seconds of rest should be allotted between sets.
Ex: 50x3 means 50 reps on each side for a total of 100, repeated 3 times

*We recommend (not mandatory) doing your first workout at night to give your jaw the most time to rest.

*Workouts recommended every other day to give your jaw muscles time to rest and grow.

                 Months 2-3 and Beyond
Chew 2 Crystals simultaneously every other day. Each day slowly increase the reps your jaw can handle based on your experience level. Feel free to chew causally as well for maintenance. Keep in mind this is not comparable to regular chewing gum. Be prepared to stop when your jaw becomes fatigued for the day.
