    What the gurus are saying

    The formula covers dark circles and de-puffs with impressive pigmentation and hydration, but reviewers split sharply on whether it holds up when you layer makeup or moisturizer. Most gurus praise its Expression Proof Technology and say it won't crease if you set it with powder; others argue the effects are temporary, cracking when you layer products. Best reserved for photos or short events, not daily wear.

    "These It Cosmetics Bye Bye Under Eye Concealers, oh my god, I love them. So I got shade deep warm is my normal under eye shade, and then to highlight, I have rich warm. These are so good. They cover well. They have a nice radiant finish because if you're covering under eye after 40, you probably don't want something mattifying because that will tell all your business. It will be all in the settled lines. And who needs something clocking you like that, right?"

    "This is a great concealer if you're looking for concealer that helps to camouflage dark circles broken capillaries fine lines and wrinkles, make you look more refreshed, less tired, but doesn't crease and doesn't accentuate the appearance of fine lines and wrinkles, especially when you set it with powder. It is super hydrating, it's super pigmented so a little bit goes a long way. You don't need a lot because often when you use a lot of concealer that is when it can easily crack and kick up. This one, because it's super richly pigmented, has what they call the expression proof technology that essentially prevents it from kicking and cracking so that way it doesn't make you look older and doesn't make you look like you have more wrinkles than you really do. This technology contains a blend of ingredients that helps to essentially hydrate the under eye area which already is pretty delicate, so hydrolyzed collagen peptides, hyaluronic acid and vitamin E. All around a great under eye concealer that's hydrating that won't make you look older, a little bit goes a long way, doesn't crack, and it's just a really elegant under eye concealer that I highly recommend."
    Top Pick: under eye concealer

    "I hate this concealer. It's so thick and gelatinous and tacky, like clay goop on your under eyes. And forget about trying to set it, it doesn't set. It's like trying to set wet Play-Doh. When I first tried this I was obsessed, so much coverage, so moisturizing, and then you start to try other concealers and you realize like this is a mess. It's messy to use, it's messy to blend, and I'm willing to bet half the people using it don't even realize it's causing creasing and accentuating their fine lines and wrinkles because it's so thick. The one technique that actually did help it look better was to warm it up between your fingers, really warm up a thin small amount and then tap it in. You would have to use so little but it would last you years. I rate it a 2.5. If I can't set something it's miserable."

    "This is something I may actually buy and try. It's an under eye concealer, which is one of the few things that actually can at least temporarily get rid of dark under eye circles, obviously not permanently removing them, but under eye concealer is one of the more practical things you can do to address dark under eye circles on a day-to-day basis. This has niacinamide, which is an ingredient I love, good for redness and hyperpigmentation, so if you have actual discoloration under the eye that may be beneficial. It has magnesium and sodium phosphate, which is a stable form of vitamin C. It may have a decent opportunity to actually penetrate the skin, especially under the delicate eyelid skin. It may help as an antioxidant to combat oxidative stress that could further weaken the barrier, but whether or not it's going to get in and boost collagen, we don't have much research in that regard. This also has petrolatum, which is good for reducing water loss, and it's waterproof so it'll stay on there, which is great in this humidity that we're existing in here right now."

    What the evidence says.

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

    Retinoids

    Retinoids are among the best studied ingredients in dermatology, with solid evidence for acne and for the fine lines and rough texture that come from sun exposure. Dryness and flaking in the first few weeks are common and usually settle.

    Vitamin C

    Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

    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.
