With all of the new beauty products that keep popping up, it's rare to find one that stands the test of time, or one that is universally endorsed. Laneige's Lip Sleeping Mask is one such product; since its debut in 2015, almost every A-lister has either used it or carried it in their makeup bag.

When I say everyone loves it, I mean everyone. Laneige Lip Sleeping Mask's laundry list of A-list superfans includes Charli XCX, Sydney Sweeney, Leslie Mann, Naomi Osaka, Gracie Abrams, and Kate Moss. Our editors even named it one of Marie Claire's best lip balms, and people swear by this $24 lip balm. That's why I'm excited that it's now discounted to under $20 on Amazon (prices vary slightly by flavor). It's one of the best beauty deals I've found in the retailer's massive sales section, and that's saying a lot, however, considering that there are literally thousands to sort through

here: three versions of the balm-the original Berry formula, a vanilla-scented option, and a citrusy grapefruit can be grabbed until tonight, October 9, for less.

The cult-favorite Lip Sleeping Mask is an overnight addition to your regular nighttime skincare routine. Essentially, it's a slugging-style skincare product for your lips: it locks in moisture and leaves them plump and healthy by the time you wake up. But it can also be worn under your favorite lipstick during the day.

If you're already on the Laneige train, you can (and should!) stack it with the brand's best-selling Glowy Lip Balm, now on Amazon, or the OG Sleeping Mask to protect your delicate skin from the icy cold headed your way this winter I mean it!!!) You should know that there are tons of other goodies from this brand on sale, including a lightly tinted balm/gloss hybrid. Originally $19, today they are all available for $13.

Get one (or all) of Laneige's lip balms now and your future self will thank you. You'll have the shiniest, donut-like lips ever for under $30. And thanks to Prime shipping, you'll have glossy, hydrated lips by the weekend.
