Funny we’re talking about this as I just saw dermatologist on Friday for annual one over. They told me to use mineral sunscreen. Elta MD was what they recommended. Based on info Gurgeh posted here a few weeks ago I had been trying to get an hour in the sun after work by doing some river fishing.That chart is entirely consistent with the standard medical narrative on sun exposure.
Skin cancers, like many other types, take multiple decades to manifest. In 2024 the average melanoma patient is 66. Their primary exposures would have come in the 80's and earlier. People who were born post ~1980 haven't lived long enough yet to get their cancers. The increasing rate per 100k population is a demographic effect of aging populations. Proportionally speaking there are 50% more people over the age of 65 now than in 1980. They also live longer, thus not dying before cancers emerge, and we have a great deal more early screening and diagnosis. Fortunately, despite that the incidence rates are higher mortality has been about flat.
There are some questions to be answered about why sunscreen use hasn't reduced skin cancer rates as we had all hoped for, but their curious inefficacy doesn't mean that the sun isn't something to be concerned about. (The main theories have to do with the fact that until recently chemical sunscreens have not blocked the UVA light band well, that sunscreens have given a false sense of security and people have increased their exposure, or that chemical sunscreens have some counterbalancing toxicities.) What's not particularly debatable is that UV light is ionizing radiation and causes DNA damage linearly with exposure. That's just physics.

Foler , IMO, wear mineral sunscreens when out for prolonged periods and supplement Vit D as necessary.
It’s interesting. I noticed the sun towards the end of the day doesn’t feel like it’s burning my skin or like Gurgeh and a few others have said, it doesn’t really burn you. So I skip sunscreen here.
I have to wear sunscreen though if I’m doing work outside multiple hours of day and need to cover up or I’ll burn. At most I’ll skip the wide brim hat for a few hours to get a little sun (with sunscreen) but the mid day sun here is brutal.
