Your Body Has Been Keeping Score All Along

Now You Can See It

The Prysm iO measures your antioxidant status in 15 seconds — no needles, no lab, no waiting.

Most people who want their own Prysm iO feel healthy. That's not the point.

The point is that your body reflects the cumulative impact of the choices you make every day...every meal you've eaten, every supplement you've taken, every hour of sleep you've had, and every stressful week you've lived — for years.

The Prysm iO gives you a measurable way to track the impact of those choices over time.

For the first time, you get to see it.

What It Measures

Carotenoid levels in your skin.

Carotenoids are the powerful antioxidants found in colorful fruits and vegetables — the reds, oranges, and yellows. They accumulate in skin tissue in direct proportion to how well your body is absorbing and using them.

Your skin carotenoid level is a window into how well your body is defending itself against oxidative stress — the cellular process most closely linked to aging, immune function, and long-term health.

High carotenoid levels are associated with a younger biological age. Low levels indicate your body may not be getting the antioxidant protection it needs.

Daily oxidative stressors include:

Pollution, UV exposure, poor diet, chronic stress, and smoking. Your score reflects how well your body's defenses are holding up against these pressures right now.

How It Works

The Prysm iO uses patent-pending Spectral Rai technology.

Step 1: Place the pad of your index finger over the lens. The scan begins automatically.

Step 2: In 15 seconds, the device makes over 700,000 hyper spectral light absorption measurements beneath your skin.

Step 3: An AI calibration system referencing Raman spectroscopy converts those measurements into your Prysm Score.

Step 4: A colour indicator shows your score zone. Full results and trend tracking are available in the Prysm iO app.

Does It Work?

Nu Skin conducted a double-blind, placebo-controlled clinical study comparing Prysm iO score changes against a validated earlier scanner.

46 participants, ages 20–65. Those taking certified supplements twice daily for 12 weeks showed an average increase in carotenoid score of 43–46%. Those taking a placebo showed no significant change.

Participants using certified supplements showed measurable improvements in their carotenoid scores. Participants using certified supplements showed measurable improvements in their carotenoid scores. You can see those changes over time.
