A compact fingertip scan measures carotenoids in about 15 seconds, delivering a personalized Nutrition Health Score without the need for lab tests.

Nu Skin launches Prysm iO, an AI-powered intelligent nutritional wellness platform that uses skin scanning to deliver personalized insights on antioxidant levels and nutrient uptake.

The device sells for $375 in the U.S. and will roll out to additional Nu Skin markets in the coming months.

Company leaders and experts endorse Prysm iO: CEO emphasizes its milestone for personalized wellness; the Scientific Advisory Board Chair highlights access to precise nutritional insights; a researcher notes validated measurement capability from a published study.

Prysm iO officially launched on April 2, 2026, marking Nu Skin’s push toward personalized health solutions in the wellness space.

Executives frame Prysm iO as a shift from guesswork to science-backed, personalized wellness insights.

The system provides actionable feedback on how daily nutrition and supplements influence antioxidant status, enabling users to track progress and adjust routines over time.

The platform analyzes genetic data, biometrics, lifestyle factors, and health goals to generate customized supplement and nutrition plans.

Clinical validation includes a study led by Dr. Zoe Draelos showing a strong correlation (R2 0.75–0.77) between Prysm iO skin measurements and blood carotenoid levels across diverse skin types, indicating reliability comparable to established optical methods.

Prysm iO supports ongoing monitoring and adjustment of recommendations to adapt to changing needs, using a comprehensive assessment process.

The product emphasizes ease of use by removing lab visits and complex testing, while enabling ongoing tracking of nutrition and supplement adjustments.

The same study, published in the Food and Nutrition Journal with 97 participants, reinforces the strong skin-to-blood carotenoid correlation.
