What does my Prysm Score mean?

Your Prysm Score: What does it mean?

You’re making intentional choices—eating better, adding supplements, trying to stay consistent. But one question still lingers: Is it actually working? 

Your Prysm Score is designed to help answer that. It gives you a clearer view of your nutritional wellness by reflecting how your daily habits show up in your body over time. Not based on assumptions, but on measurable insight.

What you’re actually measuring

Prysm iO gives you a nutritional health score by measuring carotenoid analytes in the skin, an important biomarker of antioxidant status. What makes carotenoids unique is that they accumulate in your skin over time. Because of that, they act as a reflection of your long-term nutritional intake rather than short-term changes.

Rebecca Major - Education and Research Senior Scientist for Nu Skin, explains:

“Your Prysm Score is an indicator of your nutritional wellness. It measures carotenoids, a natural class of antioxidants found in colorful fruits and vegetables. These compounds accumulate in your skin over time, and they reflect long-term nutritional intake. Carotenoids have been widely studied for many health benefits, and they're correlated with healthy aging. In addition to diet, carotenoids can also be found in supplements, so increases in your Prysm Score are a sign that carotenoids from your diet and supplements are actually being absorbed and available to support your wellness.”

What the science shows

The connection between your score and your habits is supported by clinical research.

In a study conducted with Professor Cai of Shanghai Jiao Tong University, researchers evaluated how Prysm scores relate to diet, lifestyle, and skin attributes across nearly 600 individuals. The findings revealed clear patterns between everyday behaviors and antioxidant levels.

Key findings from the study include:

Nutrition patterns

• Diets rich in fruits, vegetables, and whole foods were associated with higher scores
• More frequent consumption of fried foods, sugary drinks, and sweets related to lower scores

Lifestyle habits

• More consistent sleep routines were linked to higher scores
• Regular exercise was associated with higher scores
• Lower levels of sun exposure were associated with higher scores

Visible skin attributes

• Individuals with higher scores reported:
  • Better skin smoothness
  • Better skin hydration
  • More even-looking skin tone

Together, these findings reinforce a simple idea: your score reflects a combination of habits working together over time, while also pointing to a connection between internal wellness and visible skin appearance.

Why your score changes gradually

It’s natural to expect quick results, but your Prysm Score is designed differently. Since carotenoid levels change gradually, your Prysm Score is shaped by ongoing habits rather than isolated choices. One healthy meal or a single off day is unlikely to significantly impact your number.

Instead, your score responds to patterns—what you do regularly. This approach helps shift the focus away from quick fixes and toward habits that are more sustainable and meaningful over time.

Living longer isn’t the only goal. Increasingly, the focus is on how well we live over time. Lifespan refers to how long you live, while healthspan reflects the quality of those years—how consistently your body is supported through daily habits.

Your Prysm Score offers insight into that bigger picture. Because it reflects antioxidant status and ongoing patterns, it helps you understand how your nutrition and lifestyle choices are influencing your overall wellness.

Tracking your score makes that insight more actionable. It allows you to see how your habits are reflected over time, helping you build a more informed and consistent approach to long-term health.

What influences your score over time

To better understand what your score means, it helps to know what contributes to it. While every individual is different, your Prysm Score is shaped by a combination of factors that work together rather than independently.

Nutrition plays a central role, particularly the intake of colorful fruits and vegetables. Consistency with supplementation can also support your overall nutritional intake. Alongside that, lifestyle habits like sleep, activity levels, and daily routines contribute to how your body maintains antioxidant levels. No single factor determines your score on its own. It’s the combination—and the consistency—that matters most.

What your score can show over time

One of the most valuable aspects of your Prysm Score is the ability to track it over time. Instead of relying on how you feel alone, you can begin to see how your habits are reflected in measurable ways. Small, consistent changes can begin to show up as gradual improvements, reinforcing the connection between your choices and your results. Progress may not happen overnight, but it becomes visible with consistency.

The bottom line

Your Prysm Score reflects how your nutrition and lifestyle choices show up in your body over time. It isn’t a judgment or a fixed label. It’s a tool that helps you better understand your baseline, track your progress, and make more informed decisions moving forward. Because when you can clearly see what’s happening inside, it becomes easier to stay consistent—and keep improving.
