Do powder sunscreens really provide protection?Updated 7 months ago

We aren’t sure where people get this idea. Our sunscreen has had to go through multiple FDA-required tests to prove that it provides at least the protection on the label. And every batch is tested several times to be sure that it meets the standards of the product as a whole, so you really can count on the coverage on the label if you apply correctly (generously, see our how to apply guidelines) and reapply as directed (at least every 2 hours outdoors, and if using water resistant products, after 80 minutes of swimming or sweating.

  • SPF 30, when applied and reapplied as directed, protects from 96.7% of UVB rays.
  • SPF 40, when applied and reapplied as directed, protects from 97.5% of UVB rays.
  • SPF 50, when applied and reapplied as directed, protects from 98% of UVB rays.
  • No sunscreen protects from 100% of UVB rays.
