"One of my all-time faves by IT Cosmetics is their Bye Bye Dark Spots. [...] I just tap this in with my fingers in the under eye area and then over the mobile lid. Cover up those veins a little bit. Cover up that redness. [...] I think this color might be a little bit too light for me. I don't like a really light shade in my under eye area anymore."

"This is the IT Bye Bye Dark Spots, and I absolutely love it. It just basically erases any imperfections very easily. [...] It's very lightweight, all the redness is diminished, and it's a very good daytime look. It's not heavy. It just [...] gets rid of all the veins on my upper lid, brightens up the lower lid. I can even use it during the day to touch up. It's great for the inner corner brightening that up without looking over cakey. It just becomes one with my skin."

"I just use this as an under eye concealer and I gotta say it didn't really cover under my eyes very well. I have very minimal under eye darkness and it didn't even cover my little tiny bit of under eye darkness. It just was kind of a fail for me."

"I just assumed since it was It Cosmetics that it would have really really good coverage but be lighter weight than their other concealer because it's bye bye dark spots and I don't even see this covering even my little bit of under eye darkness it's just so sheer. It seems like it's not covering anything."

What the evidence says.

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

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

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.

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.
