Stars aren’t keeping their lips sealed about their love for this balm.

Everyone from Kate Hudson to Kyle Richards to Kendall Jenner has publicly raved about the Laneige Lip Sleeping Mask — and with Amazon’s Prime Day finally here, the rarely discounted bestseller is on sale for 20% off.

So many stars have hyped up the hydrator, in fact, that it just might be easier to name someone who hasn’t praised its powers.

And Kendall Jenner once told the same outlet she uses it “to put a little shine on” — after all, you needn’t save the product for only overnight use.

When Page Six Style Editor Elana Fishman put it to the test earlier this year, it became her “long-lasting daytime balm of choice,” too.
