What the gurus are saying

What keeps reviewers coming back is this eye butter's intensive moisturizing power. Gurus consistently praise the rich, buttery texture and how substantially hydrating it feels on the delicate eye area, exactly what you'd hope for in an eye product. The fact that people are finishing bottles and repurchasing tells you this isn't just hype, it's something they genuinely rely on and return to.

"Their eye butter from this line is great too. I love it, and I finished that one up as well, so I need to do some repurchasing."

"This has been doing it from Klairs, their Fundamental Nourishing Eye Butter. Again, this is a well-aging eye cream. It's got its peptide complex. I reviewed it a couple of times, but I do just appreciate how moisturizing it is. And it doesn't migrate. I like those textures that immediately sink into the skin, kind of dries down, absorbs really quickly, but leaves this area just really well protected. Even overnight with the heating units, this keeps this area well moisturized. I can also use it on my upper eyelids. I apply by dabbing because it feels like it absorbs almost immediately. It's not the kind of eye cream that you can drag and just massage or anything like that."

Overnight Winter Skin Reset - How I Got My Glow Back!

My 2025 Skincare Heroes!

"There are two eye creams that I reach for the most this year. The first one is from Klairs, their Fundamental Nourishing Eye Butter. I love this because of its creamier texture and it's just really, really moisturizing and I've needed it. This is one that I started using around the fall mainly because I noticed that this area was just getting really dry and crinkly. This is a richer eye formula, still absorbs beautifully into the skin, does not migrate into the eyeballs. It just doesn't go all over the place. I can even put it on my upper eyelids and it just makes everything lubricated."

Korean Skincare You Need for Fall & Winter!

"One of my favorite fall winter eye creams or evening eye creams is this one from Klairs, their Fundamental Nourishing Eye Butter. This is a beautiful buttery eye cream that is rich, substantial, very moisturizing. [...] This just moisturizes, smooths, and seals. The texture though, it is a silky silky butter. I also love that this has four peptides in it, which includes copper peptides, my favorite, and a giralene, which is really good at relaxing the muscles around the eyes that produce wrinkles. This also has an antioxidant tea complex as well as caffeine."

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.

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.
