Water Sleeping Mask.

"This is the OG sleeping mask and probably what Laneige is really known for. It's a lightweight gel mask that you'll apply in place of your moisturizer or on top of your moisturizer, but it's meant to be left on overnight to do its work as you sleep so you don't wash it off. [...] You can use it as needed like a few times a week or nightly as your nighttime moisturizer if you choose. It's got this hydrolyzed mineral water and beta glucan that is really unique in maximizing skin hydration absorption, helping to soothe and moisturize your skin as you sleep. You can use it so many different ways. You can use it as needed for dullness or hydration, or [...] when you're traveling, putting this on in flight can really help to reduce that dehydration that your skin gets while you're flying."

"It's a sleeping mask it can be used in place of your moisturizer at night time or on top of your moisturizer at night time, but you could even use it as a moisturizer during the daytime so it's very flexible. It really is meant to infuse your skin with a lot of hydration as you're sleeping and help to restore your skin through that restful process. I do think that it delivers on the hydration. It may not be the most hydrating out there anymore, it may not be the most innovative product out there anymore, however I don't see a lot of sleeping mask products available at Sephora so I think in this market it definitely has a renewed interest and renewed innovation. [...] I used it many years ago and I liked it then, it kind of fell out of my routine, it didn't grow along with me, but I do think it is a nice product."

"The Water Sleeping Mask is mainly made of silicon, glycerin, and a few extracts. Glycerin is an amazing ingredient for skincare that helps with the skin barrier and makes things feel nice. However, fragrance is quite high up in the formulation, and it also has essential oils such as linoleic acid oil, which can sensitize the skin if left on. Since this is a leave-on product that you're using overnight in a thick layer, if you have skin sensitivity, this could be the reason why you're experiencing sensitivity. You might want to look for something that's fragrance-free and allergen-free instead."

"No pass. I don't like that product. I don't understand why it has such a cult following because if you're going to make a sleeping mask you want it to be like super rich and moisturizing so that you can wake up with glowy skin. But every time I've used that product my skin is so dehydrated and dry in the morning, which is an impressive feat considering that normally my skin is super oily and I'm going to wake up with skin grease anyway. So the fact that it can dry out my skin overnight is impressive in a bad way."

"This is the Water Sleeping Mask from Laneige. This one has mineral water in it, which can help to balance the skin's microbiome, and it's going to have a little bit of fragrance as well, so be careful if you're sensitive to fragrance, this may not be a great option for you. But this is kind of a boost of hydration on top of your regular moisturizer, you put it on and go right to sleep, so it's not the kind of thing you'd use as a morning moisturizer, but it's great for nighttime."
