Your grandparents spent all day outside.
Farmers. Builders. Beach holidays. Kids disappearing after breakfast and coming home at sunset.
Now people burn in 30 minutes.
The sun didn't change.
You did.
Your skin is built from the fats you eat.
Modern diets flooded it with unstable polyunsaturated fats from industrial seed oils.
UV light oxidises those fats, producing inflammatory by-products and oxidative damage.
Melanoma rates in America:
1950: around 1 in 500
2020: around 1 in 50
During that same period, seed oil consumption exploded.
The sun hasn't become more dangerous.
Maybe we've become less resilient to it.
After 6 to 12 months without seed oils, most of your skin cells have been replaced.
Those new cells contain far less stored linoleic acid.
Thousands of people report tanning more easily, burning less, and spending far longer in the sun than they could before.
Maybe the answer isn't just what you put on your skin.
Maybe it's what you built your skin from.
