You know those teeny tiny beads inside your facial cleanser, body wash, toothpaste, and exfoliators?The ones that make you feel extra clean? Polyethylene Microbeads make YOU feel extra clean, but they're making our waters the farthest from clean. As you may know, they're used in many cosmetic products as an exfoliating agent. What you probably don't know, is that those little beads are actually made of plastic. Plastic is not biodegradable, and the beads are so small that they slip right through the sewage filter process. There are more than 300,000 microbeads in a typical bottle of facial scrub, and now 20% of our waterways are made up of these plastic particles. Hmph.
