The future of wellness is measurable

Most of us know we should eat more colourful fruits and vegetables.

We know antioxidants matter.
We know lifestyle matters.
We know sleep, stress, sunlight, nutrition and inflammation all affect how well we age.

But the question is:

How do you know if your daily choices are actually showing up in your body?

This is where PRYSM iO becomes so exciting.

PRYSM iO is a wellness technology device that measures skin carotenoid status — giving you a personalised PRYSM Score. In simple terms, your PRYSM Score is a reading of carotenoid antioxidants in the skin, which can offer insight into your internal antioxidant status, colourful nutrition habits and overall “skin from within” support.

For me, this is where beauty and wellness become much more intelligent.

Not guesswork.
Not vague wellness.
Not just “eat well and hope for the best.”

But:

See. Measure. Transform.

What is a PRYSM Score?

A PRYSM Score is a skin Carotenoid score generated by the PRYSM iO device.

Carotenoids are a class of antioxidant plant pigments found in colourful foods such as carrots, tomatoes, pumpkin, leafy greens, peppers, apricots, berries and marigold-derived lutein. They help protect the body from oxidative stress — the daily wear-and-tear caused by poor diet, stress, smoking, lack of sleep, UV exposure, inflammation and other lifestyle pressures.

According to the PRYSM iO clinical bulletin, the device uses distinct wavelengths of light to assess skin carotenoid levels, then applies a machine-learning algorithm referencing Raman technology from the BioPhotonic Scanner to generate a skin carotenoid score, or PRYSM Score.

So your PRYSM Score is not a diagnosis. It is not a medical test.

It is a biomarker-style wellness reading that helps you understand how your nutrition and lifestyle may be influencing your antioxidant status over time.

Why does PRYSM iO measure carotenoids?

Carotenoids are powerful because they are both:

1. Antioxidant nutrients
2. Measurable markers of colourful plant-food intake

Humans cannot make carotenoids. We get them from food — especially colourful fruits and vegetables. When eaten consistently, carotenoids circulate in the body and can accumulate in tissues, including the skin.

This is why skin carotenoids are so interesting. They give us a way to see whether antioxidant-rich nutrition is showing up in the body.

We have over 100 full-length peer-reviewed articles that validate the use of Raman spectroscopy for measuring carotenoids in living tissues, and that the Pharmanex BioPhotonic Scanner has been used to detect carotenoids in intact human skin as an indicator of nutritional intake and in-vivo antioxidant status. It also notes that independent research groups have validated Raman measurement of skin carotenoids using their own devices.

This matters because PRYSM iO is built on this larger scientific foundation: measuring carotenoids non-invasively as a meaningful window into nutrition and antioxidant status.

The PRYSM iO colour score explained

The score is designed to be simple and visual.

From the PRYSM iO scanner card, the antioxidant score is presented as a colour scale:

The scanner card also includes space for a baseline score, grade and re-scan date, which is important because the real value is not just your first score — it is tracking change over time.

This is one of my favourite things about PRYSM iO.

It gives you a starting point.

Not judgement.
Not perfection.
Just feedback.

What does a higher PRYSM Score suggest?

A higher PRYSM Score suggests higher skin carotenoid status.

In practical terms, this may reflect:

• More consistent intake of colourful fruits and vegetables
• Better dietary antioxidant support
• A stronger pattern of skin-from-within nutrition
• Healthier lifestyle habits around sleep, exercise and UV exposure
• Lower oxidative burden in relation to certain lifestyle factors

The important word is suggests.

This is correlation, not a medical diagnosis. But it is still extremely useful, because lifestyle change becomes easier when you can actually see feedback.

What did the PRYSM iO clinical study find?

One of the most interesting documents we have is the PRYSM iO validation bulletin, which looked at correlations between PRYSM Scores, diet, lifestyle and skin attributes.

The study included 589 healthy individuals — 293 male and 296 female — who were scanned with both PRYSM iO and the BioPhotonic Scanner S3. Their diet, lifestyle, health and skin attributes were then assessed and correlated with their skin carotenoid scores.

The average PRYSM Score in the study was 365, with scores ranging from 140 to 800. Most people scored in the yellow/moderate zone, followed by orange and green, with fewer people in the red, blue and purple zones.

Most importantly, PRYSM Scores showed a strong positive correlation with BioPhotonic Scanner S3 scores. The correlation coefficient was 0.806, with statistical significance at p < 0.001. In simple language, people who scored higher on the BioPhotonic Scanner tended to score higher on PRYSM iO too.

That gives PRYSM iO a strong validation story.

How diet affects your PRYSM Score

The clinical bulletin found that several food groups were positively associated with PRYSM Score.

These included:

• Fruits
• Dark-coloured vegetables
• Light-coloured vegetables
• Whole grains
• Freshwater fish
• Tubers
• Eggs

In contrast, some dietary patterns were negatively associated with scores, including fried foods, sugary drinks, red meat, poultry and low-alcohol drinks.

This does not mean one single food “causes” a high or low score. It means that overall dietary patterns matter.

The message is beautifully simple:

More colour, more plants, better antioxidant support.

This is why I love the phrase eat the rainbow.

Not because it sounds nice — although it does — but because colourful foods contain carotenoids, polyphenols, vitamins, minerals and other phytonutrients that support cellular health.

How sleep, UV exposure and exercise affect your score

This is where PRYSM iO becomes even more interesting, because the score is not only about food.

The clinical study found that PRYSM Scores were negatively correlated with staying up late past midnight, used as a marker of sleep quality. People who reported almost never staying up late had higher average scores than those who stayed up late more frequently.

UV exposure was also negatively correlated with PRYSM Score, meaning more sun exposure was associated with lower scores. This makes sense biologically, because UV exposure increases oxidative stress in the skin, and carotenoids may be used up as part of the body’s antioxidant defence response.

Exercise showed a positive correlation. In the study, higher exercise habits were associated with higher PRYSM Scores compared with lower exercise levels.

This is exactly why I see PRYSM iO as a lifestyle feedback tool — not just a nutrition scanner.

Your score may be influenced by:

• What you eat
• How well you sleep
• How much oxidative stress you are exposed to
• How much you move
• How consistently you support your body

It is a window into the bigger picture.

What about skin appearance?

This is the part that makes this especially relevant for skincare.

The PRYSM iO clinical bulletin found that scores above 410 were associated with more favourable self-assessed skin attributes. People with PRYSM Scores over 410 reported higher scores for skin smoothness, hydration, pore appearance, skin tone evenness and overall appearance, and lower scores for the appearance of lines and wrinkles.

This does not mean PRYSM iO is diagnosing skin ageing, or that a high score guarantees perfect skin.

But it does support something I have always believed:

Skin health is not only topical.
It is cellular, nutritional and lifestyle-led.

Your skin is constantly responding to the internal environment — nutrition, inflammation, oxidative stress, hydration, sleep and repair.

That is why “skin from within” is not just a marketing phrase. It is biology.

Why your PRYSM Score may be low

The PRYSM iO scanner card gives a simple list of reasons why a score may be low. These include food choices or food quality, environmental toxins, inflammation, stress, obesity, pharmaceuticals, chronic illness, digestive issues, smoking and poor sleep.

I would explain this gently to clients.

A lower score is not something to feel ashamed of. It is information.

It may simply mean your body is asking for more support.

Possible contributors include:

• Not enough colourful plant foods
• Low intake of carotenoid-rich foods
• Poor absorption or digestive stress
• Higher oxidative stress
• Too much UV exposure
• Poor sleep
• Smoking
• High stress
• Inflammation
• A higher need for antioxidant support

This is where the scan becomes useful.

It gives you a baseline.

Then you can make changes and re-scan.

Can you improve your PRYSM Score?

Yes — that is the whole point.

Your PRYSM Score is not fixed. It can change as your habits change.

The goal is to support the body consistently through:

• More colourful fruits and vegetables
• Carotenoid-rich foods
• Healthy fats to improve carotenoid absorption
• Better sleep
• Less oxidative stress
• Exercise
• Targeted supplements where appropriate
• Reduced smoking, alcohol excess and processed foods
• More consistent wellness habits

Because carotenoids are fat-soluble, they are absorbed better when eaten with some fat. Think cooked tomatoes with olive oil, carrots with avocado, leafy greens with eggs, pumpkin with olive oil, or a colourful salad with seeds and good-quality dressing.

This is not about perfection.

It is about giving the body the raw materials it needs to defend, repair and regenerate.

What foods support a better PRYSM Score?

The most important foods are carotenoid-rich fruits and vegetables.

Start with:

Orange foods

Carrots, pumpkin, sweet potato, cantaloupe, mango, apricots.

These are rich in carotenoids such as beta-carotene and alpha-carotene.

Red foods

Tomatoes, red peppers, watermelon, guava, papaya.

These often contain lycopene and other protective plant pigments.

Dark green foods

Kale, spinach, rocket, parsley, chard, broccoli.

These are excellent sources of lutein, zeaxanthin and beta-carotene, even though the orange pigments are hidden beneath chlorophyll.

Yellow and golden foods

Yellow carrots, yellow peppers, pumpkin, corn, egg yolk, marigold-derived lutein.

These are brilliant for the skin and eye health conversation.

Berries and deeply coloured plants

Blackberries, raspberries, currants and cloudberries offer a wider antioxidant profile, including polyphenols, vitamin C and other plant compounds.

The PRYSM Score is specifically focused on carotenoid status, but the wider message is colour variety.

Colour is information.

Is PRYSM Score a full measure of antioxidant health?

This is an important point.

Your PRYSM Score is not a complete measurement of every antioxidant system in the body.

Your antioxidant network also includes vitamin C, vitamin E, glutathione, selenium-dependent enzymes, polyphenols, superoxide dismutase and many other defence systems.

So no — PRYSM iO does not measure everything.

But carotenoids are a valuable biomarker because they reflect colourful plant intake and can be measured non-invasively in the skin. The Raman measurement document describes skin carotenoid detection as an indicator of nutritional intake and in-vivo antioxidant status, supported by a large body of peer-reviewed research.

So I would describe PRYSM iO like this:

PRYSM iO does not tell the whole story of your health — but it gives you a powerful window into your antioxidant and skin nutrition habits.

And that is incredibly useful.

Why PRYSM iO feels different from ordinary wellness advice

Most wellness advice is generic.

“Eat better.”
“Get more sleep.”
“Reduce stress.”
“Take antioxidants.”

All true, but not very motivating.

PRYSM iO makes it personal.

When you scan, you get a baseline.
When you change your habits, you can re-scan.
When your score improves, you can see that your body is responding.

That is the future of wellness:

measure, understand, improve.

It makes healthy choices more visible.

The Electric Facialist view

As a facialist, I have always believed that skin is not separate from the rest of the body.

Your skin reflects your energy, your nutrition, your stress load, your sleep, your inflammatory state and your ability to repair.

This is why I am so excited by PRYSM iO.

It bridges the gap between beauty and biology.

It helps us move from surface-level skincare into measurable skin nutrition.

Because the future of skin health is not just about what we apply externally.

It is about what we nourish internally.

It is about how well our cells are protected.

It is about building resilience from the inside out.

And now, we can begin to measure it.

Key takeaways

A PRYSM Score is a skin carotenoid score generated by the PRYSM iO device.

Carotenoids are antioxidant pigments found in colourful fruits, vegetables and some marine foods.

PRYSM iO uses light-based technology and a machine-learning algorithm referencing Raman technology to assess skin carotenoid levels.

The colour scale ranges from red/orange through yellow, green, blue and purple.

Higher scores may reflect stronger skin carotenoid status and better antioxidant-rich nutrition habits.

A 589-person clinical study found PRYSM Scores correlated with BioPhotonic Scanner S3 scores, diet, lifestyle and skin attributes.

PRYSM Scores were positively associated with fruit, vegetable, whole grain, fish, tuber and egg intake.

Scores were also associated with lifestyle factors including sleep, UV exposure and exercise.

A PRYSM Score is not a medical diagnosis, but it can be a powerful wellness feedback tool.

The goal is to establish your baseline, make supportive changes, and re-scan over time.
