Nanotechnology: Where Dermatology Meets Science Fiction

Nanotechnology is used to develop cosmetics and skin care products which contain super small particles designed to do a certain job in the skin. For example, sunscreens can contain zinc oxide and/or titanium dioxide nanoparticles to block ultraviolet rays while minimizing the white coating on the skin. When you see the words “invisible” or “sheer” on sunscreen labels, it is likely based on nanotechnology. I bet many of the products you use incorporate nanotechnology. While it's certainly cool and has a sci fi feel, is nanotechnology safe? Find out all about this trending topic right here!
