When your claim to fame is a reality TV show, you probably aren’t one to keep personal details under wraps. Which might explain why Kendall Jenner took to her app to reveal her décolletage maintenance regimen.

Yup, it’s a thing, apparently—but don’t roll your eyes just yet. Because the hack is actually pretty brilliant: The supermodel takes her leftover eye-mask serum and applies it all over her chest.

“I always pop them on before any big event.”

“I always pop them on before any big event,” writes Jenner of the trending skin-care sheets. But instead of tossing them in the trash after she peels them off, she scoops up the leftover liquid and massages it into the rest of her face and “a little bit into her neck and chest,” says the celeb’s makeup artist Mary Phillips (who gave Jenner the idea in the first place).

This beauty hack is extra brilliant because these treatments are targeted for the ultra-sensitive layers of skin under your eyes, which is similar to that on your sternum. Talk about multitasking at its finest—I’ll keep up with that.
