Make wellness
visible.
PRYSM iO turns a quick, non-invasive palm scan into a simple wellness signal—designed to help people see patterns, stay curious, and make more intentional choices.
The idea
Wellness information becomes useful when it is clear enough to inspire action. PRYSM iO is designed around that idea: a fast measurement, an understandable signal, and the opportunity to observe change over time.
How it works
Light in.
Insight out.
Reflect the signal
Specific wavelengths of light interact with the skin and reflect back to the device for analysis.
See a trend
In approximately 15 seconds, the experience provides a skin-carotenoid wellness signal intended to be followed over time.
What it observes
Carotenoids tell a story about everyday choices.
Carotenoids are naturally occurring plant pigments—the yellow, orange, and red compounds found in many fruits and vegetables. They include beta-carotene, lycopene, lutein, zeaxanthin, and astaxanthin.
Because the body does not produce carotenoids, they come through nutrition. Over time, carotenoids accumulate in the skin, where their status can be associated with fruit and vegetable intake and broader lifestyle habits.
The value is not treating one score as a verdict. It is using repeatable feedback to notice patterns and support better wellness conversations.
TOON's perspective
When people can see a signal, better habits feel less abstract.
Measure. Understand. Adjust. Repeat.
