Against UV Material Zinc Oxide Nanoparticles 

There are a lot of sunscreens in the marketplace today. Zinc oxide nanoparticles is one of two primary ingredients (the other is titanium dioxide nanoparticles) Sunscreens are used to provide protection against adverse effects of ultraviolet (UV)B (290–320 nm) and UVA (320–400 nm) radiation. According to the United States Food and Drug Administration, the protection factor against UVA should be at least one-third of the overall sun protection factor. Titanium dioxide (TiO2) and zinc oxide (ZnO) minerals are frequently employed in sunscreens as inorganic physical sun blockers. As TiO2 is more effective in UVB and ZnO in the UVA range.

Adding Zinc oxide Nanoparticles to the cream, creams and sunscreens to protect skin from uv and sunburn damage. Zinc oxide Nanoparticles can be one of the most widely reflect ultraviolet A (UVA) and ultraviolet B (UVB), has been  approved for sunscreen by the United States Food and Drug Administration. As one of the ingredients of sunscreen,  zinc oxide nanoparticles will not be absorbed by the skin to block UVA (320-400 nm) and the effect of UVB (280-320 nm). like titanium dioxide, Because it plays an role of physical sunscreen and won't be absorbed by the skin, so also won't  irritate to the skin, not allergies and acne.
