What they flagged

  • Pricey for a lip mask

What the gurus are saying

This serum earns consistent praise for its cushiony, quenching texture that feels like liquid glass on the lips and delivers real hydration overnight. Most gurus found it plumps and softens while calming the lips, though a few felt it doesn't justify the price as a standalone product without pairing it with their lip moisturizer, and one found a competitor's version superior. It works better for those willing to layer it as a treatment serum rather than expecting it to do everything on its own.

"I would recommend the Tatcha Kissu Lip Mask. That one is incredible. Yes, luxurious, but it lasts a really long time and gives me way more hydration and moisture than the Summer Fridays one does."

"I would definitely recommend the Kissu Lip Serum. I have loved that one for four years. Overall I'm not a huge Tatcha fan but that product is incredible and I'm definitely going to be buying it myself."

"I will admit I'm a huge fan of that one mostly because it lasts forever"
I Tried Every Lip Balm Ever Made (here are the best 💄)
"The price point is absurd, but it's the Tatcha Kissu Lip Serum. I don't think I ever recommend Tatcha on my channel because of how expensive the products can be, but when I tell you that this lip serum works so well for daytime and nighttime, it gives your lips such a beautiful glow. I really don't have to apply it very often like the Glossier Balm Dotcom, like a few times a day. And even though you look at the price point and you're like damn, all that for a lip product, it really does last a long time. My only gripe with it is the size, you know, because it's in a jar like that and it's kind of taller, it's a little bit harder to put in your pockets, but I still did because I love having this product. I've used it for years. It's just incredible, absolute luxury."

"I much prefer other lip masks, whether it be like the Tatcha Kissu lip mask. That one I get way more mileage on and it does such a good job of really nourishing the lips."

My Updated Evening Skincare Routine - Unwind With Me
"This is one of the top ones I've found that works really well because my lips just get so freaking dry. Even though I cringe hard at the price point, it does last a really long time, and it's honestly one of the only lip products I've found that actually really works well."
Blind Girl Gives Me a FACIAL (ft Molly Burke)
"It is my favorite, the Tatcha Kissu Lip Mask, because I'm a lip mask addict. It's kind of like a glossier finish but it's so nice. I'm not usually one for luxury products, but with this one I'm like, oh, it's just so good, it works."
The BEST Moisturizers of 2021!
"I have no particular attachment to this brand, if anything I feel like a lot of products from Tatcha are very expensive, including this one, just a fair warning, it is a luxury product. But I use this for the majority of the year and I am very impressed with the formula. You have to use barely anything, when I dip into this I take the tiniest microscopic little bit and it works for the entirety of my lips, and it does a good job of sealing in that moisture. This formula is really really good, I am a fan of it, it is a luxury experience, so anyone who's wanting kind of a bargain, I wouldn't say this is the product for you, but if you don't mind spending money on a good quality product that works really well, I have to recommend this. It lasts a really long time, a little bit goes a long way, so in my opinion you get your money's worth. I am in love, I love this one, it's so good."
Yay
"I've never used anything from Tatcha that I thought was worth anything, and it's super overpriced, but this product was good. The Tatcha Kissu Lip Mask, I believe it has fragrance, and I loved it. I went through two, maybe three jars of it. I haven't gone back to it in several years, simply because it's very expensive, so it's kind of a splurge."

Sephora Savings Event 2023 - Skincare Products Worth Buying
"I was very surprised how much I liked this and I actually repurchased it. It was gifted to me last year and I repurchased it. I always find Tatcha products to be underwhelming and I find lip sleeping masks to be underwhelming, and it has fragrance in it which is often irritating to the lips, but this product actually works. If you have dry lips and you put this on, you wake up the following morning and the lips are hydrated, soft and smooth. It does what it says it's supposed to do. It's meant to be put on at night because at night our skin loses more water, that's what it's marketed as, a sleeping mask. Truthfully I wear it during the day. If I have dry cracked lips I'll put it on and it's really good. It's not sticky or greasy. If you're someone who does not care for using Vaseline around your mouth and you want something else, you don't like the texture of Vaseline, this you might like. Just keep in mind that fragrance in lip products is a common trigger for allergic keratitis."

HUGE SKIN CARE EMPTIES! SUMMER 2022 🗑 DERMATOLOGIST @DrDrayzday
"I finished the Tatcha Kissu Lip Mask. I was shocked and somewhat ashamed by how much I loved it. It does have fragrance in it, which can be an issue for dry lips, but it must be very little because there is no aroma. It really worked well in terms of keeping my lips soft and hydrated, and I am vulnerable to getting dry lips. This was like a dream come true, it really is a good product. When it first came out I was skeptical of the ingredient they claim is the secret to it, and there is no data for that, but it is a good product."

"I was gifted the Tatcha Kissu Lip Mask and I'm ashamed to admit I actually love it, I've finished the majority of it. I know it has fragrance, but it's actually really good. The fragrance unfortunately can be pretty irritating in the long run on the lips, but that took me by surprise, actually how much I liked it."

"The article cautions against fragrance and flavorants in lip balms, and then they're recommending a fragrance containing lip balm like the Tatcha Kisuu Lip Mask. They don't point out that it's got fragrance in it, and literally two lines above they caution against fragrance and flavorants."
Yay
"I really like the original one a lot. It's really hydrating. It's soft. It really repairs lips overnight. It's not sticky. It feels really rich and buttery. It works really good as an overnight treatment or even like a daytime lip balm. The key ingredients here are the shea butter, the pomegranate steriles, and the cocoa peptides. The Tatcha Kissu lip mask plumps and softens lips while reducing fine lines and dryness. It helps lock in long-lasting hydration overnight, and it makes your lipstick and tinted balms apply more smoothly. The key ingredients in this one are the Japanese peach extract to repair and smooth. It has the squalines for nourishment and chameleia oil for that lasting moisture."
Nay
"I do like Tatcha's lip mask. Their regular one, the pink one. The gold thing I find a bit gimmicky. Do you remember when everyone was selling those, like, gold under eye patches? It was like four karat gold under eye patch, and it's like, okay, so? It's cute. It's cute. And I think it's good for Christmas. Is it interesting to me? Actually, no, not at all. I like the product, but if we're talking about the new release in general, this isn't very interesting to me."
Yay
"It's the Tatcha Kissu Lip Serum, it's 29 bucks. It's got a matrix of 3000 peptides, vitamin E, squalene, peach kernel oil, and lanolin. No noticeable flavor although it does contain fragrance but it has no scent to it. I reviewed it, it's nice, I like it. This is my holy grail for a long time, it's still really wonderful. Great nighttime mask and thicker texture."

"The Tatcha Kissu lip mask is amazing. It's a really nice lip mask, and this is my repurchase of it. The little spatula they give you is so cute. You put it on at night before you go to bed and it's super calming. There's no fragrance in it, which is nice because some lip products can have a floral taste or minty taste that I don't like. The ingredients are great: peach kernel extract, green tea, Camellia oil, lanolin, and peptides. It's wonderful. I love it."
My Favorite Lip Balms & Lip Sleeping Masks 💋 And Lip Balms To Avoid
"I still love this one. Tatcha once a year they do like a little set where you buy something and then you get to pick like four mini sizes. I've repurchased this one multiple times. It's priced but I still love it and it's really nice. It has no taste, no scent, that's even better."
Nay
"Tatcha's Kiss You Lip Treatment, the packaging is supposed to be a luxurious experience, it locks closed and has this pillowy cushion to it, but it's not as soft as you might think. Unfortunately I just don't think this is worth $40, not in this era of lip balms. There's nothing objectively wrong with this, but it's not a problem solver on its own, it's essentially a lip serum and they want you to follow it with their lip moisturizer too. In an era where there are lip balms acting as both a treatment and a moisturizer in one, I just don't see a reason to spend this much more on a product that doesn't do enough on its own."
Yay
"For a little extra cost you can get the Tatcha kissu lip mask, which does everything that the Laneige lip masks do but in this more cushiony, more hydrating, almost more occlusive feeling lip product, it also has squalane, peptides and antioxidants like the Laneige one. The only issue is it doesn't come in different scents or flavors, but I'd rather have nicer lips overnight than like a mango lip mask."

My Honest Opinion On Skincare Best Sellers 🤔 Ultra Violette Sunscreen, Caudalie, Naturium, Tatcha
"The Tatcha Kissu Lip Serum is next to my bed on my bedside table. It's got this cushiony kind of texture to it but it's really thick but it's also watery and quenching, and it's almost like putting liquid glass over your lips. It's so nourishing and hydrating, it really does feel like it just locks everything in. They say that it works to plump out fine lines and wrinkles for a firmer, fuller look, and you have some fruit extracts and some oils in here and some soothing ingredients as well. It's just a nice lip balm that is going to help plump up the lips because it's going to lock in everything at night. I like to use a toner over the top and then the lip mask, and you just feel it. This is probably my favorite Tatcha product."

Yay
"When it comes to Tatcha, it is a little bit more clear and I have found that it's a little bit more lightweight. So if you don't want something that's thick like the Glow Recipe, or if you're like Laneige is even too thick for me and it just doesn't hydrate, Tatcha actually delivers here. It's lightweight, it's hydrating, and it's pretty. It's just a little bit more expensive, but this is a solid choice. If other people online have gotten breakouts around your lips or the Laneige leaves your lips drier, this generally does not do that."

"I love the Tatcha lip mask. I actually think I have this product. I was testing out Tatcha products and bought a bunch of the minis at Sephora. I remember it had like gold leaf in it, and it was expensive but it was good."
Yay
"It is really really beautiful and this will last you forever. While the product says lip sleeping mask, you can use it in the day as well. I use it in the morning as well, I also use it at night, so this is something that is a multi-use product and I highly highly recommend it. This is like a 10 on 10 product for me. If there are products from the Japanese category which are 10 on 10 for me, I think there are just two. It is the Canmake sunscreen and the Tatcha lip sleeping mask. These are both 10 on 10 products. 10 on 10 means I will repurchase, I would recommend, love love love."

"When I compared the Laneige one and the Tatcha one head to head with each other, I like the Laneige one better."

"This is the Kissu by Tatcha. I love this lip product. I've cleaned it out, it lasts forever. It's similar to the Laneige lip mask, but I find this a little bit more plumping.

"The tatcha Kissu has won my heart and it's not an inexpensive lip mask so I highly encourage if you're curious about this to get it during the sale. I'm going to be picking up another one, this one is almost empty, it does last forever. I prefer this as a lip mask when I'm getting ready in the morning to kind of soften up my lips before I do my makeup, and after my skin care, or if I'm not going to wear any lipstick that day I'll use this just to plump up my lips and hydrate my lips. Even though I've had a lip mask overnight which is the Lancome, it's a little bit heavier, so the Lancome for me personally doesn't work as well under makeup where this works perfectly under all my lip glosses and all my lipsticks. This is a new favorite find."

This is one of my favorite new finds of 2023. I was really unexpected, I've always been a Lanolips girl but I really actually think I like this better for some reason. My lips, it sort of plumps them up a little bit better and like I said I use it in the day just to kind of get a little plumping and lip mask and I use it at night obviously for overnight hydration."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Source: DermNet

Peptides

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.

Source: NIH, National Library of Medicine

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
