Mineral sunscreen, just like it sounds, is a sunscreen with minerals as the active ingredients. In general, zinc and titanium dioxide are the two main ingredients for mineral sunscreen. The way mineral sunscreen blocks UV damages is by the minerals sitting on the top of the skin. The natural minerals act like physical blockers, can reflect away the UV rays. It is naturally broad-spectrum and offers full-spectrum coverage from both UVA and UVB rays. It has rumor that chemical sunscreen has higher UV protection level. But the truth is that mineral sunscreen can protect the UV damages as good as the chemical one.
