Does tanning age you even in an absence of seed oils?

As we age our skin loses cholesterol
I wonder why that is and if it's inevitable
-
@Hando-Jin it’s the conversion of cholesterol to vitamin D precursors from UV light. Supplying cholesterol or cholesterol precursors to the skin can help replete it.

What depletes it though? Is it an inevitable old age thing
-
@Hando-Jin the process of UV light turning the cholesterol in the skin into the precursor to vitamin D. Too much UV and not enough cholesterol synthesis in the skin will eventually deplete it.

Why not enough cholesterol synthesis is what I'm trying to understand. Has anybody answered that? I heard Ray say it was just down to age.

I think so. It's obvious to me that excess UV is harmful even when you are more resilient. (low PUFA) 15 minutes is all your skin needs to produce max Vitamin D if i remember correctly, more than that and you're just cooking yourself for no reason. Can still get lots of healthy sun in the morning though when there's minimal UV in the sunlight.

@Ecstatic_Hamster that's really interesting.
weird question - if i put lanolin on before sunbathing, i think i would absorb more Vitamin D? As far as I can tell that's how sheep get vitamin d, they secrete lanolin which gets into their wool, the sun hits the lanolin and turns it to vitamin d, then as far as I can understand the vitamin d absorbs back into the wool and into the sheep from there? Sheep don't really groom themselves much so they're probably not licking their wool and ingesting that vitamin d lanolin that way.
-
@insufferable For that matter, I guess I would get Vitamin D just from putting lanolin on my skin, even without getting any sun myself. Since the lanolin was already exposed to the sun and thus filled with Vitamin D, back when it was still on the sheep!

Tanning makes you look younger and virile. Look at David Gandy, when he is back to his pinkoid self he looks like a retard. When tanned to Med colouring light brown he mogs. Yes he aged like shit but that was because he was always hypothyroid, his thinning eyebrows were a giveaway. He had them since 20

Age, stress, nutritional deficiencies. Most people are probably inefficient at replacing cholesterol in the skin. That's why topical lanolin is a blessing for not only supplying a substrate for vitamin D but to keep the skin youthful.
