What is Physical or Chemical-free Sunscreen?
Chemical Free sunscreens are made with zinc oxide or titanium dioxide, which cover the skin surface to establish a barrier against the sun’s rays. Zinc oxide and titanium dioxide are known as “mineral sunscreens” or “physical blockers” since they reflect and scatter UV rays. Most other chemicals used in sunscreen belong in the “chemical blockers” group because they absorb and disperse UV rays.
