IT Cosmetics Bye Bye Under Eye Illumination Antiaging Concealer is your eight hours of sleep in a tube! A full coverage concealer designed to make your skin appear younger looking, this antiaging, skin loving formula is infused with hydrolyzed collagen; vitamins A, C, and E; hyaluronic acid; and peptides. It can be used to spot treat or as an allover foundation that doesn't look or feel like makeup at all.

Beautiful skin is so much more than coverage; it's also about the look of light; and IT Cosmetics(R) has captured the look of youthful and radiant-looking skin in this tube. Without the use of any glitter or shimmer, Drops of Light Technology will make it look as though light is pouring from your skin.

How do I use it: To use as an allover foundation, use the brush to smooth the concealer on your skin like a moisturizer. To target specific areas, squeeze a pin-size amount onto the back of your hand to warm, and then dip the flat side of the brush into the concealer and smooth directly onto your skin. Use the fluffy end of the brush to buff out your concealer for a natural-looking airbrushed finish.

From IT Cosmetics.

IT Cosmetics Bye Bye Under Eye Illumination with Brush is rated 3.6 out of 5 by 335.
Rated 3 out of 5 by from Bye Bye Dark Circles So this is very good at covering dark circled but very hard to blend.. I use the little brush it came with to blend to no avail. Use very little as it goes a long way.. Very sticky like texture which I think makes it harder to blend.. Covers all dark circles for sure!

Rated 5 out of 5 by from amazing! I was a little unsure about this after reading some of the reviews but I love it! The product is thick but you do not need a lot. It took me a few applications to get used to the thickness and applying without using too much (which can give you ghost eyes). The brush is amazing too! I also use it on my nose and right above my lip to brighten those areas. At 45 I have been looking for good makeup that does not enhance fine lines and this product is a great start to my foundation routine! I have always used another brand but am slowly transitioning my makeup to IT! I started with the Super Hero anti-aging eye shadow palette and love it! Looking for more IT products as I am writing this review :)

Rated 4 out of 5 by from Good coverage, nice illumination My favorite way to use this concealer- Squeeze a dab of it onto the back of my hand, then to that add a pump of the IT CC Cream and mix together with my finger (they blend well once the concealer warms a bit). I then apply using foundation brush. The result I get is a little more all-over coverage on the days I need it as opposed to the results using the CC Cream alone. This concealer also adds just a hint of illumination which I love. The concealer is thick, so I found that it doesn't work well for me as a stand alone under eye concealer.

Rated 2 out of 5 by from Not the best I found this cream to be very thick and I was tugging at my under eye area to blend.

Rated 1 out of 5 by from Covers, But At What Cost? I’ve used this primer/concealer/foundation in all its forms. I’ve given it a good two years of trying it. I’ve “doctored” it up with a bit of moisturizer to help ease the drying & thickness. And, on top of a tried & true primer I’ve used for years. No luck. I’ve really given this product a chance! Partly for the waterproof coverage. I have MS & am very sensitive to heat or humidity and make up literally disappears/melts off my skin at times. I have dark circles & a blue vein right next to my right eye, which makes coverage more challenging. HOWEVER~this concealer is a challenge in of itself! It is very drying and if there are any wrinkles or even fine lines, it settles right in! I need to mix it with a tiny bit of light moisturizer to blend it in with a sponge. A big disappointment after trying the different formulas of the under eye concealer. And to use as a foundation (because iT; for what ever reason can’t come up with a good moisturizing powder or liquid foundation). Take the cost of the average comparable full size foundation & divide it by the ml/oz of this product? Unimaginably expensive!!! Not anymore, not for me. I loved this brand at first. I still enjoy the blush, lip colors & eyeshadow. But for me; iT isn’t the holy grail.

Rated 4 out of 5 by from Takes Practice I love the bye by undereye line. I do not use the brush because I think you need your body warmth to loosen up the product. The shades are lighter than they appear, I ordered the tan but have to mix it with the regular tan bye bye undereye to make the correct color for me, next time I'll order the deep. Great product for my dark circles.

Rated 5 out of 5 by from Great concealer I love this concealer under eye cream. I bought in med tan color. It is very creamy and it is excellent to cover up anything on the face, not just for under the eyes, I use it to also cover up red veins around the nose area. The brush is great except it would be nice if they would re-design it so that the cap clicks & locks into place when you move it up and down to use the different lengths of the brush and how about a translucent cap for the other end so that we can see if the brush cap covers without bending the bristles?

Rated 3 out of 5 by from Covers well but very thick I haven't used this much and let it sit around too long to return it so now I'm stuck with it. On the plus side, it covers quite well. However, I don't have super dark circles under my eyes or severe spots on my face so it's a bit too much for me. Ironically, for a product called bye bye undereye, I would really only use it anywhere but my undereye as it's too thick and the shade I got it too light. I also noticed that when used on my cheeks as concealer, followed by powder then blush, the blush went on much heavier than usual, as if this product was anchoring the blush to my face. So be careful what you layer on top of this. If you've got a lot to cover, this will probably work well for you. If not, get a lighter weight product.
