The science of
photonutrition.
We didn’t invent the science — we formulated around it.
No sunscreen on earth blocks all UV. Not one.
SPF 50 lets 2% of UV through — in lab conditions, with perfect application. In reality, most people apply 25–50% of the recommended amount.
The UV that gets through generates reactive oxygen species inside your skin cells — free radicals that degrade collagen, damage DNA, and drive visible aging.
Photonutrition works on a completely different level — inside your skin cells, where UV has already arrived. Sunscreen and photonutrition are partners, not competitors.
Sunscreen is the wall. Photonutrition is what happens inside it.
What carotenoids do in your skin.
When you consume carotenoids consistently, they accumulate in dermal and epidermal tissue. Aust et al. (2005) measured this deposition directly: supplementation raised skin carotenoid density within weeks.
Baswan et al. (2021) confirmed that dietary carotenoids support the skin systemically — not just at the application site, but across the whole body.
Sunscreen handles the outside. Photonutrition handles the inside. They work on completely different planes.
Your body knows where to send them.
Carotenoids don’t distribute randomly. Research shows your body routes them to where UV exposure is greatest.

women followed for 20 years. Sun avoidance carried health risks comparable to smoking.
The answer was never avoidance — it was preparation.
Lindqvist et al., 2014
Sunlight is essential. UV damage is real. Both are true.
Sunlight drives vitamin D, resets your circadian clock, and lowers blood pressure. Avoiding it costs you more than it protects you.
The answer isn’t avoidance. It’s preparation. Meet the sun well.
