Widely used in powders and creams to help cosmetics adhere to the skin. A natural, physical UVA/UVBblocking ingredient. Encourages healing, soothes and protects skin. An innovative form of microfine zinc oxide - with a particle size of less than 0.2 microns, is invisible when applied to the skin. But don't let its transparent nature fool you. Even though it's light on the skin, it's a heavyweight when it comes to sun protection. It offers true broad-spectrum UVA and UVB protection. When buying a sunscreen you should get at least an SPF 15 and preferably one that contains zinc oxide.
