Ive heard a lot about Nanoparticles. Is there any reason to worry that they can penetrate into my blood stream?
Recently there has been an increasingly concern expressed about the absorption of nanoparticles of zinc (also ZnO) and titanium (Ti02) being used in sunscreens into the skin and ultimately into the blood stream. Simply, the answer is no, there is no reason to worry. Nanoparticles used in sunscreens are too large to pass through the skin and into any body system including the blood stream. It’s important to note that sunscreen nanoparticles are generally described as particles ≤ 100 nanometers (nm). The particles being used by EltaMD for sunscreens exist in our products in the following ranges: • Zinc – 40 nm to 140 nm • Titanium – 50 nm to 150nm Any particles that have a molecular weight greater than 500 g/mole is highly unlikely to penetrate intact skin. 500 g/mole equates to a size of approximately 1 nm. Available data suggests that nano zinc and titanium do not penetrate the skin. Numerous peer-reviewed studies have validated this information. EltaMD products have been designed to p
