Cosmetic concern
Nanotechnology can be risky, but no one is regulating its use
Thanks to nanotechnology, that allows grinding particles to atomic levels, you now have face creams that spread so smoothly on your skin that only a transparent sheen is visible, no layers. While that seamless make-up is desirable, cosmetics using such finely ground particles, called nanoparticles, might not be as harmless as they are believed to be. Recent studies link them to cancer and cell death. Although nanotechnology is used in about 600 consumer products, including face creams and toothpastes, there have not been enough risk-assessment studies and regulation of their use in personal care products.
