Mystic is an ancient gum made from pure organic tree sap chunks from the Greek island of Chios - the only place in the world where mastic trees grow. The resin, "Mastiha" has been used for centuries to support facial development, oral microbiome and gut health. When chewed, it exercises the masseter muscles very effectively, which leads to a more toned and prominent jawline in adults, and for children and teens, it can support the full skeletal development of one's face (that means no braces, better breathing, and natural beauty!)
