> I’m going to keep wearing my sunscreen most of the time when I need to be in direct sun, and continue regular screening for skin cancer

Sunscreen reduces vitamin D production, but it doesn't stop it. Wearn sunscreen. Get screened. And don't stay indoors for fear of UV.

Also, getting sunburnt is not the only way to get vitamin D. Wear sunscreen and go out. Enjoy the sun. And eat healthy foods that contain vitamin D.
