It’s no surprise that Kendall Jenner spends a lot of time taking care of her face. After all, she’s a model, star of Keeping Up With the Kardashians, and constantly being photographed by the paparazzi. And when she’s done with her at-home eye mask, you just might be surprised (and intrigued) by what she does with the extra formula.

Following a tip from makeup artist Mary Phillips, Jenner uses the leftover serum inside the package and applies “a little bit into her neck and chest,” according to a post on her app. The Estee Lauder spokesmodel frequently uses the brand’s Advanced Night Repair Concentrated Recovery Eye Mask ($11). The pads deliver a formula that helps boost hydration to the lower eye area, or, as Jenner describes, “one of the easiest ways to fake a full night’s sleep.”

For an even more refreshing way to use the pads, keep them in your kitchen. “I like to pop these into the fridge or freezer so they have a cooling effect,” Phillips wrote.
