What is Zinc Oxide?

Zinc Oxide (ZnO) is an inorganic compound formed by the combination of the elements zinc and oxygen. Although it is typically produced synthetically, it can also be found naturally in the mineral "zincite." It is an active ingredient used in cosmetic and dermocosmetic products to support the skin barrier, soothe the skin, and act as a physical sunscreen.

Zinc oxide is used in cosmetic and dermocosmetic products for three main functions: to support the skin barrier, to soothe the skin, and to reflect UV rays as a physical sunscreen.

The natural source of zinc oxide is a mineral called "zincite." However, zinc oxide used commercially is typically produced by synthesis in a laboratory setting.

The chemical formula for zinc oxide is ZnO.

Zinc oxide is generally considered a safe ingredient. However, before using any cosmetic product, it is recommended that individuals—especially those with sensitive skin or known allergies—check the product’s ingredients and perform a patch test on a small area of skin. If an unexpected reaction occurs on the skin, discontinue use and consult a specialist. It is important to remember that zinc oxide is not a substitute for medical treatment.
