As someone with the skin complexion of a jar of mayonnaise, burns after ten minutes on a cloudy day, and got sun burned to the point of sun poisoning and second degree burns once in my youth - yeah, I’m going to chase that bigger number. Skin cancer also runs in my family. Once had a dermatologist tell me that I shouldn’t go out of the house without a minimum of spf 50 on all exposed skin, period. Doesn’t matter the time of year. I don’t tan. I freckle and more freckles mean more checking for the ABCs of skin cancer. Just had an age spot (according to the dermatologist) removed not too long ago because the freckle became raised, rough, and irregularly shaped.
