Zinc oxide is a natural element (mineral) that is present in soils and water. It is a skin barrier agent which means it protects the skin from external irritants and prevents the loss of moisture and supports the recovery and restoration of the skin’s natural structure and function.

Zinc oxide’s main advantage is its broad UV spectrum. It created a protective layer over the skin which reflects UV radiation. Because zinc oxide is dispersed in the sunscreen, not dissolved, it stays a powder in the sunscreen. This can cause a white (with light skintones) or purple-ish (with darker skintones) cast on the skin.
