Kelly Ripa and other celebs use this hydrating lip mask for a 'nice, juicy' pout

Your bathroom cabinet may be stocked with face creams, body lotions and hydrating hair masks — but what about something to keep your lips moisturized? For the last couple of years, social media has been in a frenzy over the Laneige Lip Sleeping Mask, and celebs have been raving about it, too. A-listers like Drew Barrymore, Demi Moore, Brooke Shields, Eva Longoria, Sharon Stone, Kate Hudson and Kelly Ripa have all declared their love, and it's even currently on sale as part of October Prime Day.

In an interview with Glamour, Ripa noted that she applies it before bed because it keeps her lips "nice and juicy." As its name suggests, it's formulated to be an overnight treatment that smoothes and hydrates as you sleep, but many people love the shine so much, they use it as a daily lip balm as well.

"I mean, why didn't I come up with this? This is the best product right now," Kate Hudson asked in a chat with British Vogue about what she keeps in her purse. "It smells awesome... This is like a must-have."

The Laniege Lip Sleeping Mask comes in a .7-ounce tub with a silicone applicator, so your fingers won’t get sticky as you apply it. But, of course, you can definitely apply it with your fingers too. Either way, it goes on smoothly and evenly, and will leave your lips soft and shiny.

Even better, it smells delicious! While the Berry flavor is by far the most popular, Amazon also stocks it in Vanilla, Gummy Bear, Cotton Candy, Sweet Candy and Grapefruit. Each one delivers an extremely subtle color (it mostly goes on clear) and they all use the same antioxidant-packed formula that's infused with vitamin C and the brand's patented technology to lock in hydration and prevent dry, flaky smackers.

Amazon shoppers have taken to the reviews to rave about the product as well. It's garnered more than 36,000 five-star ratings!

"I have literally been looking for the perfect lip balm all my life! This is it," proclaimed a fan who keeps a jar in their car and one at home. "I use it all day every day... it's so silky and refreshing, not super heavy. I have it in many scents. The color is consistently clear, so feel free to get your favorite scent without worrying if you will have purple or orange lips. I personally only wear clear gloss, but it could be worn over a color."

"I’ve only used this a few nights, and I woke up this morning and my lips feel great, better than they have in months," said a shopper who'd struggled with dry, chapped lips. "You use a tiny bit with the applicator and they feel good right away, but when I woke up today, they felt great — smooth, fuller and supple. I’m really hoping with time they look a little plumper and some of those upper lip lines diminish too. Will update if things change, but as of right now, I’m very happy."

"I had been struggling for days with peeling lips, even after applying lip balm at night. The next day, my lips would feel burnt and extremely dry," explained another. "This cream arrived in the morning, and after applying it, I haven’t had any issues all day. On the contrary, my lips look much more beautiful and hydrated. I also appreciate that you don’t have to contaminate the product by touching it with your hands, as it comes with its own applicator. The scent is also very pleasant."

"Gummy Bear is the best flavor! I love this gloss!" gushed this shopper, though they weren't so crazy about the price. "I just wish it would go on sale more often, 'cause I hate having to pay full price for it! Even though one jar lasts a very long time, I still wait for sales to pop up."

All that said, if you've been overlooking your lips in your skin-care routine, it may be time to "mask up."

If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $35 or more.)
