Open a Nutrition Conversation at
Every Recall Visit.
Prysm iO is a non-invasive wellness insight tool that estimates skin carotenoid levels with light, to start a conversation about nutrition and lifestyle. It is not a medical device and does not diagnose, treat or screen for any condition. A scan takes about 15 seconds, so it can sit beside a hygiene visit or check-up without adding chair time. Your dental care and routines stay exactly as they are. What changes is that your team gets a friendly prompt for diet and lifestyle chats, and patients get one more reason to look forward to their next appointment.
- One 15-second fingertip scan gives each patient a personal wellness score they can follow
- A visual prompt for the diet and oral-health conversations your team already has
- A talking point for school visits, open days, health fairs and community events
No obligation. A short conversation is all it takes to judge whether Prysm iO belongs in your practice.
Patients Talk About Diet. Few Can See Their Own Numbers.
Dental teams hear it every day: a patient mentions constant snacking, energy drinks or a new supplement picked up at the pharmacy. Yet there is rarely anything concrete to look at together. Prysm iO adds a quick, non-invasive scan that turns a skin carotenoid estimate into a score a patient can understand and revisit over time.

Does Their Diet Look the Way They Describe It?
Ask a patient about their eating and most will say it is pretty good. Good intentions are not a measurement, and fresh produce gives up some of its nutrient content between harvest and plate, so a diet that looks sound on paper may not tell the whole story.
Supplements taken on trust
Plenty of patients take a daily product because someone recommended it, with no personal reference point. Asking about it fits the whole-patient conversation a good dental team already has.
A personal starting point
The scan reports an individual carotenoid-based score rather than a population average. It is easy to introduce in the chair or at reception and sits comfortably alongside routine dental care.
A money-back policy
Nu Skin operates a money-back policy on certified, Prysm-eligible products: if a score has not improved after 90-100 days, the purchase can be refunded, subject to Nu Skin's Terms and Conditions.
Swap guesswork for a number that you and your patient can look at together, visit after visit.
What Sits Behind the Score
Patients regularly ask the dental team whether they should be taking anything, and a considered answer builds trust. The Pharmanex range centers on carotenoids and other everyday nutrients, so patients can follow their own score next to their food and supplement choices and read each product's label for themselves. Whether and how you discuss products at all is a decision for you, within your regulator's and employer's rules.
Lutein and other carotenoids
Some products across the range include lutein alongside other carotenoids. Carotenoids are the pigments the scanner estimates in the skin.
Omega-3: EPA and DHA
Marine Omega is an omega-3 supplement supplying EPA and DHA, the fatty acids found in oily fish, to complement a varied, balanced diet.
Vitamins and minerals
LifePak is a multi-nutrient daily supplement providing a range of vitamins and minerals to complement a varied, balanced diet. Permitted product statements differ by country, so please read the label for your market.
A fruit-and-vegetable beverage
JVi is a fruit-and-vegetable beverage that is a source of vitamin C and also contains carotenoids, an easy addition to a varied diet.
The Quality Process Behind the Range
Each Pharmanex formula goes through the company's 6S Quality Process: selection, sourcing, structure, standardization, safety and substantiation. Substantiation means the company documents the support for its product statements. Patients can also scan again later and follow their own score alongside the choices they make.
Record a Starting Point, Then Re-Scan
A patient who already takes a supplement can be scanned first to note where they begin. Repeat scans a few weeks later let them see how their own score has moved alongside their food and lifestyle choices. The scan estimates skin carotenoid levels, so the trend matters more than any single reading.
A Scanner at Home Too
Some patients will want a Prysm iO of their own at home, so the whole household can scan and compare scores in a spirit of friendly competition. Nu Skin has spoken of a goal of 100 million healthy households, and your practice could be where one family first hears about it.
A supplement recommended by a patient's physician or another healthcare provider should only be changed with that provider's agreement. The score is a wellness reading that sits beside, and never replaces, a dental examination or professional care.
These statements have not been evaluated by the Food and Drug Administration. These products are not intended to diagnose, treat, cure or prevent any disease. Dietary supplements do not replace a varied, balanced diet. Prysm iO is a wellness insight tool and is not a medical device. Please read each product's label for its exact ingredients and amounts.
Your Dental Care Stays Exactly As It Is.
Add a Nutrition Talking Point.
Prysm iO is not a dental product and it does not change how you examine or care for patients. It is a technology add-on that sits beside your routine visits: a 15-second scan that gives patients a personal, trackable look at their nutritional wellness to accompany the diet and lifestyle advice your team already offers.
For patients it is one more thing to look at when the talk turns to how they eat and drink. For your practice it is a way to open conversations, give recall visits an extra point of interest and, if you choose, add an optional service - without adding to chair time.
More Engaged Patients
A visit that offers a little more than a check-up and a polish is one patients remember. A score gives them something to follow from one appointment to the next and a natural prompt to talk about what they eat and drink.
A Reason to Keep Recall Dates
When people can watch a number over time, a follow-up scan becomes a gentle, low-pressure reason to keep their recall or hygiene appointment and stay in touch with your team.
An Optional Service
Some practices offer scans as a stand-alone service, fold them into a hygiene or wellness package, or use them at community events. Whether to offer it, and how, is yours to decide within your regulator's and employer's rules.

“Their trust in you already reaches beyond the chair. Give the talk about food and drink something concrete to look at.”
Putting a Number on the Conversation
Prysm iO uses optical scanning to produce a personal nutritional wellness score in roughly 15 seconds. There are no needles, no lab appointments and no complicated procedure.
The result is simple to follow, so patients can read it for themselves and bring it into the conversations they already have with your team.
Scanning the same fingertip on the same hand each time keeps readings comparable from one visit to the next, so the trend over several scans says more than any single figure. The scanner pairs with the Prysm iO app on an iOS or Android phone or tablet. Expect to spend a little time setting up the app and getting familiar with it; after that it slots easily into a patient visit.
Prysm iO is a wellness insight tool and is not a medical device. It is not intended to diagnose, treat, cure, prevent, or mitigate any disease or medical condition, and it does not replace a dental examination.
A Scan in 15 Seconds
Quick, non-invasive and portable: reception, a hygienist's room or a table at a community open day. No preparation, no needles and no lab visit.
Light-Based Measurement
Prysm iO uses hyperspectral absorption to capture more than 700,000 separate light measurements per scan, estimating skin carotenoid levels from a fingertip resting on the sensor.
One Plain-Language Score
The readings are combined into a single Prysm Score between 100 and 1000, produced by an algorithm, so patients see an easy-to-grasp number within seconds.
Progress in an App
A companion app lets patients follow their score between visits, keeping the habits your team talks about in mind and giving you a simple reason to check in.
Years of Research Behind It
Prysm iO builds on more than 20 years of Pharmanex (a division of Nu Skin) research and development, including 110 studies, 180 white papers and 18 global patents.
For Dental Teams Who Think Beyond the Chair
Prysm iO tends to appeal to dental professionals who enjoy talking with patients about the wider picture of wellbeing and are comfortable introducing new technology. It is entirely optional, and it is always your call, within the rules of your regulator and employer, whether and how to use it.
Practice Owners
Principals who want to decide for themselves whether a wellness service has a place in their patient communications, without extra hiring or longer appointments.
Hygienists and Therapists
Hygienists and therapists spend longer with each patient and already talk about snacking, drinks and daily habits. A score gives that talk a visual anchor.
Associates and Employed Dentists
Dentists working under an owner, a group or a contract who want to understand what is and is not permitted before exploring anything further.
Community-Minded Teams
Dental professionals who run school talks, open days, health fairs or workplace wellness sessions and want something that draws people to the table.
Recall-Focused Practices
Practices that would like a friendly extra reason for patients to keep their appointments, with a repeat scan giving each visit something new to look at.
Technology-Minded Teams
Teams who like introducing well-made technology to patients and want their practice to stand out locally.
Sound like your team?
If you recognize your practice in any of these, the next step is a short, no-obligation chat to see whether Prysm iO suits you.
“A scanning approach refined over several device generations, now in a fingertip-sized form.”
Prysm iO grows out of two decades of Pharmanex research, part of Nu Skin Enterprises, and was recognized in 2025 by the Titan Awards, Globee Business Awards, Good Design Awards and Big Innovation Awards. It is an established technology platform rather than a one-off gadget.
University Groups Have Studied Skin Carotenoid Measurement
Researchers at universities have published work on measuring skin carotenoids with light as part of nutrition studies. Our science page gives a plain-language summary of that background, along with the limits that apply to it.

Take Prysm iO Beyond the Practice Walls
Prysm iO works just as well away from the practice. At a health fair, a workplace wellness day or a school event, it gives people a reason to stop at your table and a relaxed way to meet your team.
Attract
The compact scanner and its glowing light ring draw people to your table at health fairs, school events and conferences far more readily than a stack of leaflets.
Offer
Invite visitors to try a free 15-second scan. It is quick, non-invasive and gives each person something fun in return for a minute of their time.
Talk
The score gives a natural opening to chat about food, drinks and everyday habits, and to mention what your practice offers.
Follow Up
With the person's permission, note their details and send a friendly follow-up. Always respect the marketing and data-protection rules that apply where you practice.
