From Plate to Skin
When you eat carotenoid-rich foods, some of those pigments are absorbed and eventually deposited in skin tissue alongside other body tissues. This is what makes skin measurement possible — the carotenoids that matter for scoring are physically present at the surface, not just in the bloodstream.
Why This Matters for Measurement
Because skin carotenoids can be measured without a blood draw, they've become a practical way to estimate antioxidant-related nutrient status quickly and repeatedly, which is much harder to do with lab-based blood testing.
Frequently Asked Questions
Are skin carotenoids the same in everyone?
No — levels vary based on diet, skin tone (which can affect light-based readings), and individual absorption differences.
Do skin carotenoids have a color?
Some do — beta-carotene contributes to orange tones — but at normal dietary levels the effect on skin appearance is generally not noticeable.
