When you think of sleep masks, a lip mask might not be the first thing that comes to mind, but hey, this is 2026. Anything’s possible.
And Laneige’s Lip Sleeping Mask (£21 from Cult Beauty UK /$25 from Sephora US) has actually been quite the talking point online for some years now – mostly positive, sometimes negative.
So, I decided to try it for myself to see whether I agreed with the general consensus.

Did it change my lips for the better? Does it feel odd wearing a lip product to bed? And what about those rumours about the brand not being completely cruelty-free?
Keep scrolling to read my honest review.
- Price: £21 / $25
- Tested for: Just over four weeks
- Our verdict: A genuinely effective overnight lip treatment that left Philippa’s lips noticeably smoother and better hydrated. It isn’t a miracle fix for chronically dry lips, but for softness, moisture and sheer enjoyment, it lives up to much of the hype.
- Our rating: 4.5/5
- Compared with: More nourishing than Ole Henriksen’s Pout Preserve and every bit as moisturising as Summer Fridays’ Lip Butter Balm, while offering more of a dedicated overnight-treatment experience.
What is Laneige Lip Sleeping Mask? Key ingredients & flavours
Made by hugely popular K Beauty company Laneige (best known for their lip products, as well as for their innovative creamy toner and sleeping masks), this mask is packed with moisturising ingredients and antioxidants like berry fruit complex, murumuru seed, and shea butter.
Lip Sleeping Mask also promises to soften and nourish lips as you sleep with help from coconut oil. Finally, it protects from external aggressions thanks to vitamin C and promises to keep the hydration going for the whole of the next day.
The mask comes in 14 flavours, each with tantalisingly edible names like ‘Gummy Bear’, “Watermelon Pop”, and ‘Peach Iced Tea’. The flavour I’m trying is Sweet Candy, one of the brand’s bestsellers.

How I tested it
I applied Laneige’s Lip Sleeping Mask nightly for just over four weeks, always after washing my face and before continuing with the rest of my skincare routine. During that time, I didn’t use any other lip products at night but did carry on using my normal lip balms and glosses during the day.
Texture, application & first impressions
My initial thought when unboxing the mask was how big the pot was. Well, for a lip product anyway. It’s a chunky 20g, slightly bigger than your average lip balm, but as this isn’t marketed as a balm I guess it’s not so surprising.
My Sweet Candy flavour came in a pretty pink pot and upon unscrewing the lid, I noticed the mask itself was pink too. It smelt of sweet candyfloss (funny that) but not overbearingly so and I instantly wanted to dig my finger in and have a go.
Then I noticed it actually comes with a tiny spatula which looks like an eyeshadow sponge. So I dug that in instead and ended up taking out far too much.
I knew this because when I applied it to my lips, I was greeted by a thick layer of glossy lacquer. The first piece of advice – use much less than you think.

After wiping a little bit back into the pot, I applied what seemed to be the correct amount (I’d say half a pea-sized) and realised that even with less product, it is still incredibly glossy and thick on your lips.
It felt beautiful – there was no way any moisture was going to creep out of my lips that night – but it did feel very odd to be applying a thick gloss onto my lips at bedtime.
On that note, I know it’s not meant to be a gloss, but that’s what it felt like. A bit like when you’re watching The Real Housewives of Salt Lake City and one of the women miraculously wakes up in bed with a full face of makeup on, glossy, plumped lips ‘n all.
But rest assured. Whilst this might look and feel like a lip gloss, it doesn’t go that one step further. That’s right, I’m talking about a tint. Contrary to popular confusion, the Laneige Lip Sleeping Mask is colourless, and rightfully so. The last thing I want are lipstick marks all over my pillowcase thank you very much. People will talk.
So anyway, I went to bed with glossy lips. Strange. But when I woke up, the gloss had sunk in, leaving only just a tiny bit of noticeable product left on my lips.

The instructions say to gently rub your lips with your finger to remove the excess. There wasn’t much for me (my lips must have been thirsty) but I did as I was told and was left with a pleasantly smooth pout.
My Lip Sleeping Mask results
I wouldn’t say my lips were exactly chapped when I first started using this but they’re definitely smoother than they were – their surface is more even and it’s obvious I’ve been treating my lips with more care than usual. And given how quickly a couple of days of skincare neglect can take their toll, this can only be a good thing.
The hydration does indeed last all day after you’ve slept in it. My lips feel almost tingly the morning after I’ve applied it too but I don’t experience peeling as I know some have.
For extra hydration and plumping effect, I’ve heard some like to apply a layer of hyaluronic acid serum underneath. It’s an interesting thought but I can’t honestly see how this would make the product any better – it performs so well on its own.
Don’t get me wrong, there’s nothing wrong with doing a lip care routine but in my opinion, this product is all your lips really need if you’re looking for smoothness and locking in moisture.

So we’ve established it’s a good hydrator. But have my lips completely changed long-term, in an epiphany sort of way? No. They’re just a bit smoother and smell extra sweet while the product is sinking in.
Some people apparently use it as a lip balm during the day too, rather than just as a sleep mask. Lip Sleeping Mask is safe for daily use, but I’m just not sure I could stomach it. This stuff is thick, and it’s hard to only take a small swipe without getting a gloop of product, so using it as a lip balm would just be too heavy for me. Plus the taste of candy floss mixed with my lunchtime salad might not *quite* gel.
Anyway, since Laneige actually do a dedicated daytime lip/gloss too (I’ve reviewed it separately here), I definitely have options.
On a serious note, there have been rumours that this brand isn’t completely cruelty-free.
The parent company of Laneige, Amorepacific Corporation, says they do not test on animals unless required by law, which means the brand hasn’t yet been classed as completely cruelty-free.
Laneige is also not vegan, with some products containing animal-derived ingredients like beeswax, honey and lanolin. As far as I know, the Lip Sleeping Mask is free of all three.
Overall, I’m happy with how it performs though and will continue to use it around twice a week since it is doing a great job of keeping my lips hydrated and soft. And lipstick seems to be going on easier too – bonus.
What other users are saying
The one result I really wanted to see, but didn’t, was a more plumped pout! I don’t expect to wake up like Angelina Jolie but a bit of extra fullness wouldn’t have gone amiss.
But according to the reviews, others have experienced it. “Leaves my lips plumped, love to use it during the day instead of a gloss too,” writes Eve on the Look Fantastic website. “This is the best lip mask I have ever used, it stays on all night and my lips look plumper in the morning,” adds Nicola.

Other users haven’t been impressed with the mask’s overall results though. Donna said, “When I wake up there is no product left to wash off and my lips feel more dry (and actually sore) than when I started using it. I’ve actually stopped this week and they feel better already.” I noticed there wasn’t much to wash off too but didn’t experience any soreness – it was more a greater awareness of my lips as a whole as I could feel the aftereffects for most of the day after.
How it stacks up against its main competitors
Let’s face it, the lip care market is a pretty saturated one at the moment (hello lip oils, serums, and exfoliators) – and the luxury lip balm market even more so.
I’ve been lucky enough to try Laneige Lip Sleeping Mask’s main competition over the years though too, so if there’s only room for one $20 plus balm in your collection (and who could blame you) allow me to share my thoughts on how it stacks up.
- Summer Fridays Lip Butter Balm: The closest to Laneige’s Lip Sleeping Mask, in my opinion, but in tube form. It is every bit as moisturising, adds a similar gloss level, and is quite a bit easier to use – plus you can get tinted formulas for more versatile daytime wear. Anyone who loves the ritual of having a separate night routine to round off the day will likely still prefer Lip Sleeping Mask though.
- Ole Henriksen Pout Preserve: A really lovely balm, and a winner in our 2025 beauty awards, no less. Easier to use, since it comes in tube form, but not quite as nourishing as Lip Sleeping Mask. Pout Preserve does offer the advantage of added peptides though so if you find these help with plumping (I personally don’t) then it would be the choice for you.
- Laneige Lip Glowy Balm: I actually slightly prefer Lip Glowy Balm to Lip Sleeping Mask- but it’s a very close call- purely because I find the tube format so much easier to use. My favourite treat is alternating the two for day and night though.
- Glossier Balm Dotcom: A solid lip balm that doesn’t pretend to be a gloss. Not as hydrating as Laneige’s Lip Sleeping Balm but easier to carry around with you for daytime use and another good one for those who like their balms with a tint.
Is Laneige Lip Sleeping Mask worth it?
At £21/$25 it’s quite a lot to spend on one pot of what is essentially a lip balm, with extra benefits. But remember, you only need to use a tiny amount so this pot lasts and lasts. You wouldn’t be needing to top up in a hurry, believe me.
And the affordable alternatives
The most affordable alternative? Errm, a pot of Vaseline (it has the same thickness, almost the same glossiness, not quite the same smell!), since it’s an occlusive that forms a barrier over lips and helps prevent moisture loss. It also offers a nice little gloss effect and you can even get tinted Vaseline balms too if that’s your thing.
Some people also swear by generic nipple cream as an alternative, while I also really like Lanolips too for about half the price of Laneige’s product.
The takeaway
If you can get past the fact that you’re basically applying a thick gloss before bed, and you have a similar experience to me, you and your lips will undoubtedly enjoy the brilliant benefits of this lip mask.
It isn’t tinted but it is quite thick so apply it sparingly. Remember to rub your finger over the excess in the morning and apply it consistently (around two to three times a week) to get the best results. I saw a noticeable difference to the overall hydration of my lips straight away but after a week or so, the difference was even greater.
Having said that though, for super dry lips (for example eczema sufferers of tretinoin users), this isn’t the first product I’d be reaching for to fix long-term dryness (for that, I’d be looking to fragrance-free and derm-recommended solutions like Vaseline).
Instead, where Lip Sleeping Mask truly shines- in my opinion- is in bringing hydration and softness to lips that are already averagely healthy. It’s a genuine skincare treat in that respect, offering enough noticeable benefits alongside being a genuine joy to use. The kind of beauty win-win I can always get on board with.
