Your Skin Carotenoid Score is a measurement of the antioxidant carotenoids stored in your skin — a recognised, non‑invasive indicator of how many fruits and vegetables your body is actually absorbing, and of your overall antioxidant defence.
What carotenoids are
Carotenoids are the natural pigments that give fruit and vegetables their bright colours — the orange in carrots, the red in tomatoes, the deep green in kale. When you eat them, your body stores them in your skin and tissues, where they work as antioxidants, neutralising the “free radicals” that damage your cells.
What your score tells you
A higher score generally reflects a diet rich in plant nutrients and a stronger antioxidant reserve. A lower score can be an early signal that your body’s defences need support — often before you feel any symptoms. It’s one of the very few wellness markers you can actually watch change over time.
How we measure it
At Biology of Balance we read your score in about 60 seconds using the PRYSM iO scanner — no needles, no blood, just a gentle light‑based reading from your fingertip. You get a clear number on the spot.
Why it matters
Your score is your starting point. From there we build a personalised plan — the right nutrition and Nu Skin Pharmanex supplements — to help raise it. On your 12‑week re‑scan, you can see the number climb: visible proof your plan is working.
