Prysm io is a cutting edge testing tool that non-invasively measures carotenoid levels in the skin, providing an immediate indication of a person's overall antioxidant levels. How does it work? Prism iO uses thousands of hyperspectral absorption measurements per second to accurately assess skin carotenoid levels. What can be measured, can be improved.
