11 Cult Classic Products Used Backstage at NYFW

The Product: Vaseline Lip Therapy Original Lip Balm Tin ($4)

Spotted At: Libertine

What the Pros Had to Say: "If you dip your eyeliner brush into the Vaseline lip balm and then swipe it into your powder eye shadow, you'll completely change the texture of the product — in a good way," says lead makeup artist for Too Cool For School, Katie Jayne Hughes. According to Katie, by dipping your fine-tipped eyeliner brush into the emollient formula, you'll create your own, custom-colored gel liner that you can either smudge easily for a "greasy, rock-and-roll" texture or apply precisely for a pointed cat eye.
