This Changes Everything

Prysm iO involves more than just tracking general health trends; it means understanding whether the carotenoids from your diet and supplements are being absorbed and made available to provide measurable benefits. In just seconds, our device measures key carotenoid nutrient levels in your skin, which serves as a reliable indicator of healthy aging. Carotenoids are powerful antioxidants that help protect your body from oxidative stress and free radical damage—two significant contributors to aging. With Prysm iO™, you get proof, not promises.  

Backed by over 20 years of antioxidant research—and built on the legacy of the pioneering Pharmanex® LifePak and one of the world’s largest, longest-running antioxidant databases—Nu Skin is uniquely positioned to lead the future of wellness. Prysm iO harnesses this expertise, combining advanced AI and machine learning to deliver powerful insights and breakthrough innovation.

Discover Prysm iO

Prysm iO is a cutting-edge testing tool that non-invasively measures carotenoid levels in skin, providing an immediate indication of a person’s overall antioxidant levels.

How Does It Work?

Prysm iO uses thousands hyperspectral absorption measurements per second to accurately assess skin carotenoid levels. Its patent-pending Spectral Rai technology measures light absorption and applies machine-learning calibration referencing Raman technology to generate your carotenoid score.

What Are Carotenoids, And Why Should I Care About Them?


Carotenoids are natural antioxidants found in many fruits and vegetables, playing a crucial role in protecting your body from oxidative stress. As powerful antioxidants, they help combat free radical damage and support overall health. Measuring carotenoid levels provides a real-time insight into your antioxidant status, allowing you to track and improve your wellness with lifestyle choices and targeted nutrition and supplements.
