As someone who has greasy skin (like an oil slick) getting wrinkles of course has some bearing on sun exposure, but having naturally oily skin will really be what keeps your skin looking great over the years.
I don't seek the sun out, but I also don't completely stay pale. However, at 40 I have zero wrinkles. I also have no stretch marks, no loose skin, perky boobs and no cellulite. I think this has everything to do with the oily skin I got from my dad. He is nearing 70 and looks amazing.
My poor irish husband's skin is a mess and he does not, and cannot tan. He has that thin white skin that wrinkles like a paper bag. He mom looks 75 years old and she in in her 50s.
