I've got CeraVe - broad spectrum SPF 50 with zinc. I get white streaks all over but I haven't burned with it.
I'll use Neutrogena SPF 70 Broad Spectrum liquid on my face and hands often since it feels less greasy. It's the "bad" kind though with the chemicals.
I take Vit D daily, but I've reached the point due to earlier sun damage that I get a rash if I'm out in the sun for too long (too long varies with time of day but can be as little as 15 min).
Whether you use sunscreen or not, know the ABCDs of melanoma...
look for
Asymmetry of moles
Border (uneven can be a concern)
Color (multiple colors can be a concern in one mole)
Diameter (over 6 mm, keep an eye on).
Any mole or spot that looks different from others around it should be checked.
Dark moles on palms of hands or soles of feet are a primary concern. A friend's wife died from melanoma on her foot. She was black, so a "base tan" sure wouldn't have made a difference.
If a mole starts bleeding, get to the dermatologist ASAP.
Melanoma is one of the easiest cancers to treat... IF it's caught early. (Disagreed with below...I may be incorrect.)
If not, it's nasty.
