1. The Earth we live on possesses a form of easily
accessible and beneficial natural electric energy
2. Positively influence human physiology in various
ways
3. A clear improvement of facial blood flow in grounded
subjects but not in sham-grounded subjects
Conclusion

4. Restores blood flow regulation to the face that may
enhance skin tissue repair, health and vitality, and
optimize facial appearance
5. May also have broad implications for overall
cardiovascular function and health
