Have you always used more common brand name sunscreen that was chemical based? We were taught that sunscreen required us to slather on thick layers, going through the product rather quickly, needing to buy more sooner. Chemical-based sunscreens need to absorb into the skin before they become effective as a UV inhibitor. It’s why the directions read to wait 15 minutes before going into the sun.
Mineral-based sunscreens sit on top of the skin and act as a shield against the rays. They’re thicker going on and the product in the bottle lasts longer between purchases. Ours is water-based so it means less oil to clog your pores, won’t heat your skin or make you feel greasy. When applied correctly there should be a silvery sheen to your skin, not a heavy whiteness.
