It's dried resin/sap picked from the mastic tree.

STEEL® – Jawline Gum comes from the Greek island Chios- where mastic gum originated 2,500 years ago.


With daily chewing, it's possible to see a noticeable difference to the face and jawline in 3 weeks. 

People who have never trained their jawline have some "newbie gains" to look forward to. These can come pretty quickly.

Stick to it for 3-6 months to maximize results.

There is 1.2oz or 30grams of pure mastic gum in each pack.

That's enough to last 3 weeks with daily chewing.

The best results are seen by chewing both with the front teeth and the molar teeth at the back.

Chewing with the front 4-8 teeth puts emphasis on the lower, outer portion of the masseter muscle on your jaw (see below).

That is the most important section for improving the jawline's appearance.

Chewing the back molar teeth puts emphasis on the entire masseter muscle and some on the temporalis muscle.

This chewing technique will exhaust the masseter muscle the fastest.

I recommend using both techniques.

Your order will arrive in 2-8 days in the United States.

We ship with UPS.
