Sunscreen SPF List
Scientific data on UV protection from natural oils, mineral sunscreens, and conventional sunscreens compiled from peer-reviewed research
We compile SPF ratings verified by lab tests from studies published in peer-reviewed scientific journals, which may be more reliable than manufacturer-reported values or other biased sources.
We originally investigated only natural oils, then expanded to include mineral sunscreens. We have also collected research on conventional sunscreens.
