FAQs

Please read our FAQs page to find out more.

What muscles does Jawline Core target?

Jawline Core mainly targets the masseter muscles located at the back of your jaw — the primary muscles responsible for chewing. That said, the exercises will activate most facial muscles, including the Temporalis, Medial Pterygoid and Suprahyoid Group. 

What effects may I see on my face when using Jawline Core?

Jawline Core is designed specifically for jawline definition by targeting the masseter muscles through controlled resistance. With regular use, you may see increased firmness in the lower face and light to moderate muscle growth in the masseter, depending on resistance level, session duration, consistency, and individual response — much like traditional strength training.

How often should I use it?

We recommend using it for at least 15–20 minutes per day. Beginners can start with 2–3 days per week and gradually increase frequency as they adjust. Over time, you can progress to higher resistance levels, extend the duration of daily sessions, and increase overall weekly use.

Can I combine it with other Mayena products?

Yes. Jawline Core works well as part of a full routine — especially when paired with the Full Face Trainer or chewing gum. To see best effects, each product would need their own dedicated exercise time, such as 15 min using the full face trainer and 15 min for jawline core. 

Are the products safe to use?

Yes, the products are made from BPA-free, food-grade silicone rubber, and designed for regular use. However, it's not a medical device and should be used responsibly. If you have any medical conditions or concerns, consult a healthcare professional before starting facial training.

How do I clean it?

Rinse with warm water after each use. Air-dry and store in their containers.
