Nanoparticles in sunscreens
A number of SunSense sunscreens contain nanoparticulate titanium dioxide. Nanoparticulate titanium dioxide, and similarly zinc oxide, has been used in sunscreens for many years.
Using nano sized particles of titanium dioxide and zinc oxide in sunscreens helps to reduce the white sheen on the skin produced by these two ingredients while retaining the sunscreen properties.
Many studies have shown that nanoparticulate titanium dioxide does not penetrate the skin. The particles remain on the surface of the skin and in the outer dead layer (stratum corneum) of the skin.
Other evidence shows that titanium dioxide is not irritant to the skin and does not cause allergies or photoallergies.
