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?"

    "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."

    "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."

    "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."

    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.
