tell me how a run of the mill dermatologist profit from sunscreen?
the natural alternatives; sure there are mineral sunscreens who use titanium dioxide and zinc oxide as uv filters which are abundant in nature. they are as natural as putting clay on your face.
just note that even chemical sunscreens aren’t harmful to you but if it will make you feel better, please wear mineral sunscreen.

these two are great for daily use. won’t leave white cast, don’t feel greasy at all and won’t cause acne.
