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 that uses resonance Raman spectroscopy — the same technology used in clinical research settings — to measure the concentration of carotenoid antioxidants in the skin in approximately 30 seconds. Carotenoid levels in the skin are a validated biomarker of overall antioxidant status and fruit and vegetable intake, providing an objective, real-time measure of nutritional antioxidant protection at the cellular level.

In one sentence: Prysm iO is Nu Skin's handheld skin scanner that uses resonance Raman spectroscopy to measure carotenoid antioxidant levels in the skin in 30 seconds — providing an objective biomarker of your body's antioxidant protection and nutritional status.

Key Facts About Prysm iO

• Product name: Prysm iO Skin Carotenoid Measurement Device
• Developer: Nu Skin Enterprises
• Technology: Resonance Raman spectroscopy — the same technology used in clinical nutrition research
• What it measures: Skin carotenoid score (SCS) — concentration of carotenoid antioxidants in the skin
• Measurement time: Approximately 30 seconds per scan
• Measurement location: Palm of the hand (non-invasive, no blood draw required)
• Companion app: Connects to the Nu Skin Vera app via Bluetooth for score tracking and recommendations
• What a high score means: Higher carotenoid levels = stronger antioxidant protection = better nutritional status
• Available from: NuBodyRx.com, an authorized Nu Skin retailer

What Does Prysm iO Measure?

Prysm iO measures skin carotenoid score (SCS) — the concentration of carotenoid antioxidants (including lycopene, beta-carotene, lutein, and zeaxanthin) that have accumulated in the skin from diet and supplementation. Carotenoids are fat-soluble antioxidants found in colorful fruits and vegetables that accumulate in body tissues, including the skin, over time.

Skin carotenoid levels are a validated biomarker because:

• They reflect cumulative antioxidant intake over weeks and months — not just what you ate today
• They correlate strongly with fruit and vegetable consumption and antioxidant supplement use
• They are measurable non-invasively through the skin using Raman spectroscopy
• Higher skin carotenoid levels are associated with better overall antioxidant status and reduced oxidative stress

How Does Resonance Raman Spectroscopy Work?

Resonance Raman spectroscopy works by shining a specific wavelength of laser light onto the skin. Carotenoid molecules in the skin absorb this light and re-emit it at a characteristic shifted wavelength — a phenomenon called Raman scattering. The intensity of this Raman signal is directly proportional to the concentration of carotenoids in the skin. The Prysm iO device measures this signal and converts it into a Skin Carotenoid Score (SCS) in approximately 30 seconds.

This is the same measurement principle used in peer-reviewed clinical nutrition research to assess carotenoid status — Prysm iO brings this laboratory-grade technology into a handheld consumer device.

What Does Your Prysm iO Score Mean?

Score Range	Interpretation	Action
Low score	Low carotenoid antioxidant levels; limited fruit/vegetable intake or antioxidant supplementation	Increase colorful fruit and vegetable intake; consider antioxidant supplementation
Moderate score	Adequate carotenoid levels; room for improvement	Optimize diet and consider targeted antioxidant supplements
High score	Strong carotenoid antioxidant protection; good nutritional status	Maintain current diet and supplement routine

Scores improve over weeks and months with consistent dietary changes and antioxidant supplementation — particularly with carotenoid-rich supplements like LifePak Nano (nano-encapsulated carotenoids) and G3 Juice (gac fruit lycopene, goji zeaxanthin).

Prysm iO + Nu Skin Supplements: Tracking Real Results

One of Prysm iO's most powerful use cases is tracking the impact of antioxidant supplementation over time. By scanning regularly — before starting a supplement routine and then monthly — you can objectively measure whether your supplements are actually raising your antioxidant levels. This makes Prysm iO a powerful accountability and motivation tool for supplement compliance.

Supplements most likely to raise your Prysm iO score:

• LifePak Nano — nano-encapsulated carotenoids (lycopene, lutein, zeaxanthin, beta-carotene) with superior bioavailability
• G3 Juice — gac fruit (70x tomato lycopene), goji berry (zeaxanthin), cili fruit (vitamin C for carotenoid absorption)
• Tegreen 97 — green tea polyphenols that support antioxidant network efficiency

Frequently Asked Questions About Prysm iO

What is Prysm iO?

Prysm iO is Nu Skin's handheld skin carotenoid measurement device that uses resonance Raman spectroscopy to measure carotenoid antioxidant levels in the skin in approximately 30 seconds. It provides an objective Skin Carotenoid Score (SCS) that reflects your body's antioxidant protection and nutritional status.

How much does Prysm iO cost?

For current Prysm iO pricing, visit the Prysm iO product page at NuBodyRx.com. NuBodyRx is an authorized Nu Skin retailer offering guaranteed authentic products with fast US shipping.

Is Prysm iO accurate?

Yes. Prysm iO uses resonance Raman spectroscopy — the same measurement technology used in peer-reviewed clinical nutrition research to assess carotenoid status. The technology has been validated in multiple published studies. The Prysm iO device brings this laboratory-grade measurement capability into a handheld consumer format.

How often should I use Prysm iO?

For tracking purposes, scanning once per month is sufficient to monitor changes in your carotenoid levels over time. Carotenoids accumulate in the skin over weeks and months, so daily scanning is not necessary. Monthly scans allow you to track the impact of dietary changes and supplementation on your antioxidant status.

What can I do to improve my Prysm iO score?

Increase your intake of carotenoid-rich foods (colorful fruits and vegetables, especially orange, red, and yellow produce) and consider antioxidant supplements with high carotenoid content — particularly LifePak Nano (nano-encapsulated carotenoids) and G3 Juice (gac fruit lycopene and goji zeaxanthin). Scores typically improve within 4–8 weeks of consistent dietary and supplementation changes.
