Remember when I tried out the $125 soap? You know, the one that used nano-silver particles, among other fancy ingredients? Well, the kind of nanotechnology used in it is now under fire. Cue the hypochondria.
Eighty times thinner than a strand of human hair, nanoparticles are used in beauty products to improve the delivery power of ingredients. It might sound all cool and futuristic, but is it? Since these little specks are so tiny, they can make their way into the body's protective barriers, which could cause toxic results.
This has consumer groups worrying about the safety of this fairly new technology and lack of regulations thereof. Most consumers aren't even aware of the use of nano in the first place, let alone any safety problems that exist. Are you concerned?
