Sunscreen SPF List
Last updated July 14, 2026
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.
SPF at a Glance
Oil bars show laboratory-measured SPF from the peer-reviewed studies cited on each page; mineral and conventional product bars show labeled SPF. Even the strongest natural oil measures well below the SPF 30+ that health organizations recommend.
