NAIL POLISH: I got RGB. They’re a great, great brand that I think has the best colors on the market, but they’re also non-toxic, which I really appreciate.”—Sophia Bush
WHY IT WORKS: There’s no formaldehyde, toluene, DBP or camphor in this line of polishes; and the long-lasting, non-chip formula comes in a wide range of over 40 trendy colors. The brand also offers a powerful soy-based nail color remover.
