A PRYSM iO scan works by shining a safe, low‑intensity light onto your skin and measuring how it reflects — revealing the level of antioxidant carotenoids stored in your body in about 60 seconds, with no needles and no blood test.
The science, simply
Carotenoids — the antioxidants from fruit and veg — have a unique optical “signature.” The PRYSM iO uses reflection spectroscopy (hyperspectral light analysis) to detect that signature in your skin. Different molecules reflect light differently, so the scanner can read precisely how much carotenoid is present.
What happens in your appointment
- You rest a fingertip on the scanner.
- It takes a painless, ~60‑second reading.
- You receive your Skin Carotenoid Score — a clear number.
- We talk you through what it means and build your personalised plan.
Is it safe?
Completely. It’s non‑invasive — no needles, no radiation, no discomfort — and uses a validated method also used in nutritional research to assess antioxidant status.
Why it’s different
Most health checks only tell you what’s wrong once you already feel unwell. A PRYSM iO scan gives you a measurable, objective number now — so you can act early, then track your progress on a re‑scan.
