Zinc oxide is a compound composed of zinc and oxygen that is commonly used in a variety of applications, including in cosmetics, sunscreens, and as a dietary supplement.
In cosmetics, zinc oxide is often used as a natural sunscreen because it helps to block both UVA and UVB rays. It is also used in other skincare products for its anti-inflammatory properties, which can help to soothe skin and reduce redness.
In dietary supplements, zinc oxide is a common form of zinc that is used to support immune function, wound healing, and overall health. Zinc is an essential mineral that plays a role in many biological processes in the body, including DNA synthesis, protein metabolism, and cell growth and division.
While zinc oxide is generally considered safe, exposure to high levels of the compound through inhalation can cause respiratory irritation and lung damage. However, when used topically or ingested in recommended amounts, zinc oxide is generally well-tolerated and has a low risk of side effects.
