Zinc oxide is generally considered to be safe for human consumption, though excessive consumption can lead to adverse health effects. It is also used in a number of industrial applications, including in sunscreens, paints, and ointments, but it can be toxic if inhaled or ingested in high doses.

Is zinc oxide harmful to your skin?

Zinc oxide is a mineral that is used in many sunscreens and cosmetics because it is known to protect the skin from the sun’s ultraviolet (UV) rays. However, it is important to note that the form and concentration of zinc oxide in a product can affect how safe it is. Zinc oxide in its nanoparticle form can be absorbed through the skin and may be toxic, while zinc oxide in its non-nano form is not known to be harmful. To be safe, it is recommended that you use a product that contains zinc oxide in its non-nano form.
