80-90% of the visible signs of ageing come from the sun. This is why, in older people, you'll find their body generally looks younger than their face. This is because clothes protected their body from the sun, but their faces were fully exposed.
Always wear sunscreen on your hands, face and neck every time you go outside. If you're the type of HN'er that is on the computer all day and rarely goes outside, doing this on the few occasions you do will take away one of the only opportunities the sun will have to age you.
A lot of people are already vitamin D deficient and avoiding sun or using sunscreen more will make it worse. The health risks and consequences are much greater than that of sun exposure, which is likely why sun exposure decreases cancer risk and mortality rates substantially, despite the increased risk of skin cancer.
looking young is a fine goal, but this advice is too general on a forum like this. The actual UV index varies wildly based on location and time of year.
Your advice would be crazy in seattle or london for example. Except summer time, or if one works outdoors.
You recommend I put on sunscreen when it’s cloudy, i can’t see the sun, and the weather app shows a UV index of 3? You did say “every time” lol. I’ve noticed people in this thread (not you specifically) don’t have the capacity for nuance on this subject. It’s baffling to me.
Questions people should ask themselves:
- how long will i be outside?
- is it early morning or early evening? if so sunscreen is pointless.
- what is the peak UV index in my location today? is it 2 or 11?
- am i genetically predisposed to skin cancer, or have very light skin?
