What: Zinc oxide is a natural mineral which provides the safest
and most effective protection against UV rays. Unlike chemical
sunscreens, zinc forms a physical barrier on the skin,
reflecting the sun’s rays rather than absorbing them. Zinc Oxide
is the best performing ingredient for blocking both UVA and UVB
rays. Zinc is nontoxic and less irritating to skin than chemical
sunscreens (Wiki). Zinc, commonly in powder form, tends to leave
a white residue on skin. To eliminate this unwanted whiteness,
manufacturers have begun reducing the particle size of zinc,
known as nano-particles (under 100 nanometers). But nanos have
come under scrutiny over possible health risks. A special
process allows us to keep larger zinc oxide particles from
clumping whereas the smaller nano and near nano-particle zinc in
most other sunscreens clump together to form larger aggregate
particles. As a result, our large particle zinc oxide is able to
go onto the skin clear. Origin: Zinc oxide is found in the
Earth’s crust as natural min
