Sunscreens with zinc oxide are called “physical” sunscreens because they sit atop the skin and physically block the sun’s rays by scattering them. This prevents potentially damaging ultraviolet radiation from getting to the skin. Zinc oxide is proven to help block UV rays and is included in many sunscreens.
Zinc oxide sunscreens are effective against both UVA and UVB rays. They work by reflecting and scattering the sun’s rays, which reduces potential sun damage.
I hope that helps! Let me know if you have any other questions.
