Zinc Oxide is found in high concentrations in zincite crystal formations. But this crystal is somewhat rare and most commercial zinc oxide is made in factories using metallic zinc.
Zinc oxide is a very pale pigment, allowing formulators total control for skin tone colour matching. It also has a matte finish for shine-free foundations and base layers.
Non-nano zinc oxide particles are too large to penetrate, or be absorbed through the skin, making it a very effective natural sunblock ingredient.
Non-nano zinc oxide is used in reef-safe sunscreen products.
Zinc oxide effectively controls odour causing bacteria in underarm products.
