Plastic ain't fantastic, reason No. 4,972
"...tiny exfoliating beads in many facial scrubs are made of polyethylene, and once the beads get washed down the drain and make their way to the ocean, it's time for Nemo and friends to get ill. (Of course, polyethylene's also a suspected carcinogen, and as a plastic, its production is fossil fuel-intensive.)"
I find that the baking soda and oatmeal scrub does a fantastic job of cleaning and gentle exfoliation. I think the special exfoliating beads are just another marketing gimmick to get you to buy the latest and greatest. So, you scrub yourself silly, then you need to buy their special moisturizer, then you're oily so you need the special cleanser... and the cycle begins. Sometimes simple is better.
