Anecdotal, but the parts of my skin that see more sun exposure (forearms) look healthier compared with parts that are more covered (upper arms). I wonder if maybe gradual sun exposure starting from spring and increasing towards the summer is healthier compared to sudden intense tanning of the area that is otherwise constantly covered by clothes.

That can be for other reasons, though. Like one's upper arm is often looser or have more fat below the skin, making it a different texture than the more taught lower arms.

Sunlight can definitely clear up some skin conditions like eczema. I don't know about making skin healthier in general though. It 100% causes aging in skin though so any "healthier" skin you get will be totally wiped out by the wrinkly mess it becomes in your 40s. The message we should send kids is not "wear suncream; it prevents cancer" it's "wear suncream; it prevents wrinkles". Surprising how many people don't even know that. There's a famous photo that demonstrates it very obviously: https://metro.co.uk/2018/01/28/photo-truck-driver-shows-28-years-sun-damage-looks-like-7266641/amp/ https://metro.co.uk/2018/01/28/photo-truck-driver-shows-28-y... Which side would you prefer?

  I am suspicious of that driver effect being caused solely by sun exposure. If that were the case we would see the same effect in all drivers.

    It's possible that he was driving with the open window or that the window in his truck wasn't blocking much UVA.

    Here's another less extreme example: https://www.examinerlive.co.uk/news/real-life/half-lorry-drivers-face-ages-27138856 https://www.examinerlive.co.uk/news/real-life/half-lorry-dri... What else do you think it could be caused by? The sun is the obvious explanation and we know the sun damages skin. Another easy source of proof is women's skin damage patterns. Look at any old woman's naked body (if you dare) and their face, and frequently upper chest will be much more damaged than the rest of their body which has been covered by clothes their entire life.

  It isn't a wrinkly mess, it's character.

    Sure that's one way to live with it. Nobody would choose wrinkles if they had the choice though. So wear sun cream!

Lets see when you are older. The difference (number of moles, overall skin age) should be visible on most skin types
