In the past, I’ve written a lot about nail polish—even gel polish—as this seems to be the single-most effective way to get a not-so-green girl to wake up and smell the toxic chemicals. After all, it’s one thing to tell you that parabens in most conventional beauty products have been linked to hormonal disruption—yada yada yada—but it’s quite another to tell you that if you start using eco nail polish your nails will stop turning yellow. But if you’re making the switch to better lacquers—but still have old polish in a drawer—can non-toxic polish remover work for both? Yes!
