What the gurus are saying

Gurus split sharply on coverage. Some adore the lightweight serum texture and use it daily, praising the extensive shade range and how gently it wears on skin. Others need stronger coverage and found it far too sheer, even for minimal under-eye darkness. The active ingredients, mostly hyaluronic acid and niacinamide, really do work better in a moisturizer.

"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."

"The one I'm using right now is the Bye Bye Dark Spot Concealer and Serum. It can be used all over your face to cover up your spots, and also around the eye area. It's a serum formula and it's very light. If you're used to a traditional corrector, you might find this too light. If you want something a little bit better, try this out. I don't like a traditional concealer. Usually they're a little heavy, and they always tend to crease. This has been a new find for me, and I absolutely love it."

"I've been loving this lately. It's a very light under eye concealer, very lightweight, but it also helps just a little with [...] correction on the spots that have discoloration. I like to apply it with the doe foot on the back of my hand so I don't get too much. It's a fairly thin consistency, so you really can't over apply it. It has a little brush applicator on the end. My only concern is how to clean this brush applicator. It's a little bit of a problem."

"It's a one and done corrector. I just swipe above and below my eye and it gives me a one and done look. It's not like color correcting. It's a little bit more of a flat look and doesn't give that as similar of a skin-like texture, but for an easy no-makeup makeup day, just to give myself a little bit more of a refreshed eye look, I love it. I highly recommend it. It has hyaluronic acid, and it's very moisturizing."

It was my number one for 2023 and I haven't found one to beat it yet, so if you're looking for a great corrector, I love this. I think they have like 21 different shades. I just put it on the back of my hand, warm it up, and tap it in, especially in the corners where my eyes are really blue, right in my under-eye area where they're really red, and over my mobile lid."

"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."
