Crow's feet: why they appear earlier on one side of the face
«Drop by drop, the boot is filled.»
– Proverb
Find a straight-on photo of yourself in good lighting and compare both sides of your face.
If you drive a lot, it is likely that one side has more wrinkles and more sunspots. In Spain, it is the left side.
The reason lies in the car windows.
A study measured the ultraviolet radiation passing through the glass of 29 cars.
The windshield blocked an average of 96% of UVA rays. The side window, only 71%. And in some cars, less than half.
UVA rays are the ones that reach deepest into the skin and degrade collagen. They don't burn, so you don't notice them.
The sun that doesn't burn is the sun that ages you the most.
The authors believe this may help explain why more cataracts are seen in the left eye and more skin cancer on the left side of the face.
The caveat: they measured the glass, not the drivers' skin, and they were dealership cars in Los Angeles.
But the practical conclusion is clear. If you spend an hour a day in the car, the window side takes on years of extra sun.
Your face keeps count of every car trip, even if you don't.
And crow's feet are among the first to notice, because the skin around the eye is very thin.
You don't need an expensive treatment to slow it down. You need to protect that skin every day, with a protocol that has evidence.
Your 1% improvement today. Compound interest that accumulates.
Leave sunscreen in the glove box and apply a layer to your face and the backs of your hands before you start driving. And if you change cars, ask if the windows filter UVA rays.
This is what I cover in the Gray Hair and Wrinkles Protocol: how I protect the skin around my eyes from the sun you don't notice and what I do to soften the wrinkles that are already there.
Remember that I am now selling only ONE access to the Gray Hair and Wrinkles Protocol per day.
The price is set by a Dutch auction.
It goes down throughout the day.
