How to Check Your Antioxidant Levels With Prysm iO

How to Check Your Antioxidant Levels With Prysm iO

Benefits, How It Works, and Price

Knowing your antioxidant levels is one of the most powerful ways to understand how well your body is protecting itself from oxidative stress, inflammation, and premature aging. Until recently, measuring antioxidant status required lab testing or educated guesswork. Prysm iO changes that.


What Is Prysm iO?

Nu Skin Prysm iO is a non-invasive wellness device that measures skin carotenoid levels, a scientifically recognized biomarker of antioxidant status. Carotenoids are powerful antioxidants found in fruits and vegetables, and their presence in the skin reflects long-term nutritional and lifestyle habits.

Prysm iO is built on decades of bio-photonic scanning research that existed long before today’s wearable fitness trackers. Bio-scanning technology was designed to measure internal wellness markers, not just activity or movement.

How Prysm iO Checks Your Antioxidant Levels

Step-by-Step Process

  1. Power on the Prysm iO device and open the Prysm iO app on your phone or tablet.

  2. Place your finger on the scanning window.

  3. The device emits safe, multi-wavelength light into the skin.

  4. In about 15 seconds, the scanner analyzes reflected light to assess carotenoid concentration.

  5. Your antioxidant score appears instantly in the app.

No needles, blood draws, lab visits, or downtime are required.

What the Prysm iO Score Measures

The Prysm iO score reflects:

  • Carotenoid antioxidant levels in the skin

  • Long-term absorption of antioxidant-rich foods and supplements

  • Lifestyle influences such as stress, sleep, smoking, and inflammation

Because carotenoids accumulate in skin tissue over time, this method provides a more stable and meaningful view of antioxidant status than a single blood test.


Benefits of Using Prysm iO

Non-Invasive and Fast

Scans take seconds and can be done anytime, anywhere.

Measures What Your Body Absorbs

Instead of guessing based on diet or supplement labels, Prysm iO shows what your body is actually using.

Tracks Trends Over Time

Repeated scans allow you to monitor how changes in nutrition, supplements, stress, or lifestyle affect your antioxidant levels.

Personalized Wellness Insight

The app provides guidance and context so your score is actionable, not just a number.

Backed by Established Science

Prysm iO builds on more than 20 years of antioxidant and carotenoid research using bio-photonic scanning technology.


Why Bio-Scanning Came Before Wearables

Long before smart watches tracked steps and sleep, bio-scanners were developed to measure internal health markers. Prysm iO represents the evolution of that original technology, shifting wellness from assumptions to measurable data.

Wearables tell you what you do.
Bio-scanning shows how your body responds.
