Nano-particles in sunscreen: Don’t get burned
Some sunscreens currently on drugstore shelves contain nano-particles. But you'd never know, because they're not labeled. And no government agency has reviewed them to see whether they're safe.
Instead, the US Food and Drug Administration has relied on manufacturers' assurances that there's no problem with smearing the nano-containing creams all over the skin - despite concerns that nano-particles may be able to penetrate the skin and cause damage once inside the body.
The International Center for Technology Assessment has launched a campaign to gather and submit public comments to the FDA by November 26. Take a look at the information and it's compiled and the comment form it provides.
