What Zinc Oxide does

Filters UVA and UVB rays as a physical sunscreen
Forms a protective barrier on dry or chafed skin
Gives creams a soft, opaque white finish

Zinc Oxide is a mineral made by burning zinc metal or by processing zinc ores. The result is a fine white powder, milled into very small particles for skincare. It is one of the most widely used mineral UV filters and a common ingredient in diaper creams and everyday moisturizers.

Formulators use it for two main reasons. It reflects and scatters UV light, and it is often chosen for sensitive skin because it is considered gentle. It also helps creams feel smooth and gives them a soft white, slightly opaque look. On the skin it can leave a faint white cast at higher levels, which usually fades as the product rubs in.

Good for

Good for sensitive skin, diaper-area care, and anyone wanting a mineral sun filter in a daily moisturizer.

Frequently asked questions

Is zinc oxide safe for sensitive skin?

Zinc oxide is generally well tolerated and is often chosen for sensitive or irritated skin. Because it sits on the surface rather than being absorbed, it is commonly used in creams for delicate areas. If your skin reacts to any product, stop using it and check with a dermatologist.

Does zinc oxide leave a white cast?

It can. Zinc oxide is a white powder, so higher amounts may leave a faint white tint on the skin. Many modern formulas use fine particles to reduce this. The tint usually fades as you rub it in.
