Curious about how your nutrition and lifestyle choices may influence your antioxidant status? The NuSkin Prysm iO™ offers a simple way to track skin carotenoid levels over time.

​

What is Prysm iO™?
Prysm iO is a compact wellness device that uses noninvasive optical technology and an AI-powered algorithm to measure carotenoid levels in your skin.

​

What are carotenoids?
Carotenoids are antioxidants naturally found in colorful fruits and vegetables, as well as certain nutritional supplements.

​

How does the device work?
Place the clean, dry pad of your index finger over the scanning lens. The device analyzes light absorption in the skin and provides a color-coded Prysm Score within seconds.

​

What does my Prysm Score represent?
Your score reflects the carotenoid levels detected in your skin at the time of the scan. Regular scans can help you observe patterns associated with nutrition, supplementation, fitness, and lifestyle choices.

​

Does Prysm iO require a blood sample?
No. The scan is noninvasive and performed through the fingertip.

​

Can I track my results?
Yes. Pair the device with the Nu Skin Prysm iO app to view your scan history, follow changes over time, and access personalized insights.

​

How can I support consistent readings?
Place the device on a flat surface, keep your finger and the lens clean and dry, completely cover the lens, and remain still throughout the scan. Follow the official instructions for calibration and use.

​

Can Prysm iO diagnose a medical condition?
No. Prysm iO is a wellness-tracking device and should not replace medical testing, diagnosis, treatment, or guidance from a qualified healthcare professional.
