The oil trend has made it to your nail polish – and for good reason. “Oil makes pigment really pop and increases shine,” says Tom Bachik, global nail designer for L’Oréal Paris. The brand’s new Le Vernis à L’Huile by Color Riche ($10) contains four types of oil – rose, lotus bloom, camellia seed and argan – which means that one coat of polish is all you need for streak-free colour.

For fall, Bachik is vibing on jewel tones (his fave in the new collection is Blue Royale) and nixing OTT nail art. “It’s not dead; we just want to take a very minimalistic approach,” he says. “Add a metallic accent – a gold sparkle, a moon, a little stud – something clean that’s intentional without being in your face.”
