Titanium and zinc are essential sunscreen ingredients and recently nanoparticulate amounts have been shown to improve sunscreen products by making them feel less thick and reducing the chalky film associated with some sunscreen formulas. Nanotechnology deals with the science of atomic size molecules, or particles measuring one-billionth of a meter. But there is some concern that nanoparticulate levels of titanium and zinc may have adverse effects because of their increased absorption capabilities and potential to penetrate organs or enter the bloodstream, possibly causing toxicity.

According to the physician-led Nanodermatology Society (NDS), fears about the use of nanotechnology in sunscreens can be laid to rest. In an official statement regarding the matter, NDS determined that nano-based sunscreens do not pose serious health risks to consumers. This statement was based on evidentiary facts including nano-titanium and zinc do not penetrate the outer layer of skin, even through hair follicles, and they do not reach living cells so there is no threat of toxicity. The statement also pointed out that consumers using zinc and titanium sunscreen products are exposed to 20 percent less UVA radiation than those using sunscreens without these ingredients.

The bottom line: slather on the sunscreen and enjoy the summer!
