We get it: A Slip 'n Slide face isn’t a good look. But, long before creams and serums, oils were the secret to youthful skin. Cleopatra (the original beauty junkie) washed with it daily. Today, the trend is gaining traction thanks to celebs including Gwyneth Paltrow, Emma Stone, and Miranda Kerr, who swear by these slick picks.
