What is Prysm iO? Nu Skin's Skin Carotenoid Scanner Explained
Prysm iO is a non-invasive skin carotenoid measurement device developed by Nu Skin Enterprises. In Nu Skin's words, it “measures carotenoid levels in your skin to assess nutritional health without blood tests,” and it “unlocks personalized insights that inspire healthier choices in your diet, habits, and lifestyle.” A scan takes 15 seconds.
In one sentence: Prysm iO is Nu Skin's handheld scanner that reads the carotenoid level in your skin in 15 seconds and turns it into a Prysm Score in the Nu Skin Vera® app.

What Does Prysm iO Measure?
Prysm iO measures the concentration of carotenoids — including lycopene, beta-carotene, lutein and zeaxanthin — that have accumulated in the skin from diet and supplementation. Carotenoids are the fat-soluble pigments found in colourful fruits and vegetables, and they build up in body tissues, including the skin, over time.
What makes that useful:
- The level reflects cumulative intake over weeks and months — not just what you ate today
- It tracks with how many colourful fruits and vegetables you eat, and with carotenoid supplementation
- It can be read through the skin, without a blood draw
- It gives you a number you can compare against your own earlier readings
How Does a Prysm iO Scan Work?
Place the pad of your index finger over the lens. Nu Skin says the patent-pending Spectral Rai Technology captures “more than 70,000 hyperspectral absorption measurements (6,000+ per second) per scan,” and that it “measures light absorption in the skin and applies machine-learning calibration referencing Raman technology.” The Nu Skin Vera® app then, in Nu Skin's words, “delivers your Prysm Score in seconds and translates it into clear, easy-to-understand feedback on your antioxidant and nutritional status.”
What Does Your Prysm iO Score Mean?
| Score Range | What it indicates | What you might do |
|---|---|---|
| Low score | A lower carotenoid level in the skin | More colourful fruit and vegetables; consider a carotenoid-containing supplement |
| Moderate score | A mid-range carotenoid level | Keep going, and scan again to see whether it moves |
| High score | A higher carotenoid level in the skin | Maintain your current diet and supplement routine |
The Nu Skin Vera® app explains what your own score means. Carotenoids accumulate over weeks and months, so a score moves slowly rather than day to day.
Prysm iO + Nu Skin Supplements
The clearest use for Prysm iO is tracking. Take a reading before you start a supplement, then again later, and you have a comparison rather than an impression.
Nu Skin says that Prysm Certified supplements are “guaranteed to increase your Prysm Score,” and lists ageLOC Youth as “Prysm certified to increase your Prysm score.”
Nu Skin also reports a randomized, double-blind, placebo-controlled study of 46 healthy adults in which participants taking targeted supplements saw “43 to 46% increases in skin carotenoid levels after 12 weeks.”
Carotenoid-containing options in the range:
- LifePak Nano — carotenoids including lycopene, lutein and zeaxanthin, in a formula where Nu Skin says fat-soluble nutrients “are pre-dissolved for superior bioavailability”
- G3 Juice — gâc fruit (lycopene) and goji berry (zeaxanthin)
- Beauty Focus Collagen+ — contains lutein, a carotenoid

Nu Skin says Prysm Certified supplements are “guaranteed to increase your Prysm Score,” and reports a randomized, double-blind, placebo-controlled study of 46 healthy adults in which participants taking targeted supplements saw “43 to 46% increases in skin carotenoid levels after 12 weeks.”
