Zinc Oxide Micronised (nanoparticles)
An innovative form of microfine zinc oxide with a particle size of less than 0.2 microns, (most is less than 1 micron) is pretty much invisible when applied to the skin.
It offers true broadspectrum UVA and UVB protection. Micronised Zinc Oxide is constituted by particles that are so small that they can actually both absorb and reflect the UV radiation. Most of the organic sunscreens block only UVB. Titanium dioxide blocks some UVA and Zinc oxide blocks more UV radiation than any other single ingredient.
