IT Cosmetics Bye Bye Under Eye Concealer Review: A Complete Guide
Are you tired of dark circles making you look tired and aged? Do you struggle with finding a concealer that actually covers those stubborn under-eye bags without caking or creasing?
The search for the perfect under-eye concealer can feel endless, but IT Cosmetics Bye Bye Under Eye Concealer might just be the solution you’ve been looking for.
This award-winning, waterproof concealer has gained cult status in the beauty world for its incredible full coverage and skin-loving ingredients.
Key Takeaways
- Incredible Coverage Power – Just a tiny dot provides full coverage for dark circles, hyperpigmentation, redness, and even tattoos without looking cakey
- Long-Lasting Formula – The waterproof, crease-resistant formula stays put for up to 24 hours without fading or settling into fine lines
- Skin-Loving Ingredients – Formulated with peptides, hydrolyzed collagen, and hyaluronic acid to improve the appearance of your skin while concealing
- Extensive Shade Range – Available in 24 shades organized by undertone (cool, neutral, warm) to match a wide variety of skin tones
- Multi-Purpose Product – Works not just for under-eyes but also for covering blemishes, redness, hyperpigmentation, and even as a foundation in small areas
What Makes IT Cosmetics Bye Bye Under Eye Concealer Special?
The IT Cosmetics Bye Bye Under Eye Concealer isn’t just another makeup product – it’s a game-changer in the concealer world. Created with plastic surgeons and dermatologists, this concealer was designed to address real skin concerns while providing makeup coverage. What sets it apart from other concealers on the market is its unique formula that combines full coverage with skincare benefits.
The concealer features what the brand calls “Expression Proof™ Technology,” which means it moves with your skin rather than settling into fine lines or creases. This is a huge benefit for the delicate under-eye area, where traditional concealers often emphasize texture issues rather than concealing them.
Another standout feature is just how pigmented this product is. Many users report that a dot smaller than a grain of rice is enough to cover both under-eye areas! This makes the $30 price tag much more reasonable when you consider how long the product will last. The formula is also waterproof, making it perfect for special occasions, emotional days, or hot weather when you need your makeup to stay put.

The Science Behind the Formula: Understanding the Ingredients
What truly makes Bye Bye Under Eye Concealer unique is its inclusion of skincare ingredients that work to improve your skin’s appearance over time. This isn’t just makeup – it’s treatment makeup that addresses the root causes of under-eye concerns while concealing them.
The formula includes:
- Peptides: These help reduce the appearance of wrinkles for smoother, firmer-looking skin
- Hydrolyzed Collagen: Contains amino acids that support the skin’s natural collagen production
- Hyaluronic Acid: A powerful humectant that attracts and holds moisture for hydrated, plump skin
- Antioxidants: Help protect the skin from environmental stressors and free radical damage
This combination makes the concealer especially beneficial for mature skin or anyone with dryness in the under-eye area. While many full-coverage concealers can look dry and emphasize texture, the hydrating ingredients in this formula help it blend seamlessly with the skin for a more natural appearance.
How to Apply IT Cosmetics Bye Bye Under Eye Concealer for Best Results
One of the most common mistakes people make with this concealer is using too much product. Because it’s so highly pigmented, a tiny amount goes a very long way. Here’s how to apply it for flawless results:
- Warm the product: Take a dot smaller than a grain of rice on your ring finger and warm it between your fingers for a few seconds to make it more pliable
- Tap, don’t rub: Gently tap the product onto your under-eye area, starting from the inner corner where darkness is typically most prominent
- Blend with care: Use either your ring finger, a damp beauty sponge, or a concealer brush to blend the edges, being careful not to tug on the delicate skin
- Set if necessary: If you have oily skin or live in a humid climate, you may want to set the concealer with a light dusting of translucent powder
Many users find that applying eye cream first creates the perfect base for this concealer, helping it to blend more easily and preventing any dryness. For those with very dry under-eyes, mixing a tiny dot of facial oil with the concealer can also create a beautiful, luminous finish.

It’s worth noting that some users find this concealer works best when applied before foundation rather than after, which is contrary to the typical makeup application order. This allows the concealer to properly adhere to the skin and the foundation can then be blended over the edges for a seamless transition.
The Complete Shade Range: Finding Your Perfect Match
IT Cosmetics has significantly expanded the shade range of Bye Bye Under Eye Concealer over the years, now offering 24 true-to-skin shades. What makes their shade system particularly helpful is that each shade name includes an undertone indicator: Cool (C), Neutral (N), and Warm (W).
The shade range includes:
- Light shades: 10.5 Light (C), 11.0 Light Nude (N), 11.5 Light Beige (C)
- Medium shades: 20.0 Medium (N), 22.0 Medium Natural (N), 23.0 Medium Sand (W)
- Tan shades: 30.0 Tan (N), 32.0 Tan Natural (N), 33.0 Tan Sand (W)
- Deep shades: 40.0 Deep (N), 42.0 Deep Natural (N), 43.0 Deep Rich (W)
Finding the right shade can be tricky with such a pigmented product, so many makeup artists recommend going slightly lighter than your foundation shade for the under-eye area to create a brightening effect. However, going too light can create an unnatural appearance or a gray cast, especially on deeper skin tones.
If you’re shopping online, the IT Cosmetics website has a helpful shade finder tool that can recommend options based on your skin tone and undertone. For the best results, you might consider purchasing two shades – one for concealing dark circles and one for covering blemishes or redness elsewhere on the face.

Real Results: Before and After Using Bye Bye Under Eye Concealer
What makes IT Cosmetics Bye Bye Under Eye Concealer truly impressive is the dramatic transformation it can create. Users with severe dark circles, hyperpigmentation, or even birthmarks report being amazed by the coverage this product provides.
In before and after images, the difference is often striking – dark purple under-eye circles completely disappear, redness from rosacea becomes invisible, and even tattoos can be fully concealed with just a small amount of product. What’s even more impressive is that despite the full coverage, the finish looks like natural skin rather than heavy makeup when applied correctly.
Many users with mature skin particularly appreciate how this concealer doesn’t settle into fine lines throughout the day. While many full-coverage products can accentuate texture issues after a few hours of wear, the flexible formula of Bye Bye Under Eye moves with the skin, maintaining a fresh appearance even after long days.
Value for Money: Is IT Cosmetics Bye Bye Under Eye Worth the Price?
At around $30 for a 0.4 oz tube, IT Cosmetics Bye Bye Under Eye Concealer isn’t the most budget-friendly option on the market. However, when you consider how little product you need per application, the value becomes much more apparent. Many users report a single tube lasting anywhere from 6 months to over a year with regular use.
The multi-functional nature of the product also adds to its value. Beyond just concealing dark circles, it can be used to:
- Cover blemishes and redness anywhere on the face
- Contour and highlight when purchased in complementary shades
- Even out discoloration on eyelids as an eyeshadow base
- Conceal tattoos or scars for special events
- Spot-treat areas as a foundation alternative
When compared to other high-end concealers that often require replacement every 3-4 months, Bye Bye Under Eye’s longevity makes it a more economical choice in the long run. Additionally, the skincare benefits mean you’re not just paying for makeup but also for treatment ingredients that can improve your skin’s appearance over time.
How to Choose Between IT Cosmetics Concealer Formulas
IT Cosmetics now offers several different concealer formulas, which can make choosing the right one confusing. Here’s a quick guide to help you decide:
- Bye Bye Under Eye: The original formula with full coverage, anti-aging benefits, and a natural finish. Best for those seeking maximum coverage with skincare benefits.
- Bye Bye Under Eye Illumination: A slightly more luminous version of the original with subtle light-reflecting particles. Great for mature skin or those who want a brightening effect.
- Bye Bye Dark Spots: A newer formula specifically designed for hyperpigmentation and dark spots on the face rather than under-eye concerns.
If your main concern is dark circles and you want a product that will last all day without creasing, the original Bye Bye Under Eye is likely your best bet. However, if you have very dry skin or want additional luminosity, the Illumination formula might be more suitable.
It’s worth noting that the texture of all these formulas is quite thick, which some users find challenging to work with. If you prefer a more lightweight, buildable coverage, you might want to explore other options like the brand’s CC+ Cream with SPF 50+, which also offers concealing properties.
The Waterproof Test: Does It Really Last All Day?
One of IT Cosmetics’ biggest claims about Bye Bye Under Eye Concealer is that it’s truly waterproof and lasts for up to 24 hours. But does it really hold up to these promises?
Based on extensive user testing and reviews, the concealer does indeed display impressive staying power. Users report the product remaining intact through:
- Swimming and water activities
- Emotional moments with tears
- Intense workout sessions
- Hot, humid weather conditions
- Long work days (12+ hours)
The key to making it last is proper application and setting. Many users find that while the concealer has natural staying power on its own, a light dusting of setting powder helps it remain perfect throughout the day. The waterproof formula is particularly beneficial for special occasions like weddings, where emotional moments might otherwise lead to makeup meltdowns.
However, it’s worth noting that this waterproof quality also means you’ll need a good makeup remover to take it off at the end of the day. Many users recommend using a cleansing balm or oil-based makeup remover to gently dissolve the product without having to tug at the delicate eye area.
Common Concerns: Addressing Potential Issues with the Product
While many users love IT Cosmetics Bye Bye Under Eye Concealer, it’s not without potential drawbacks. Here are some common concerns and how to address them:
Thickness and Blendability
Some users find the thick consistency difficult to blend. Solution: Warming the product between your fingers first or mixing with a tiny amount of eye cream can make application much easier.
Creasing
Despite claims of being crease-resistant, some users still experience settling into fine lines. Solution: Use less product and set with a light dusting of finely-milled powder. The “baking” technique can also help prevent creasing.
Color Oxidation
Some shades may oxidize (darken) after application. Solution: Choose a shade slightly lighter than you think you need, and always test the product for at least 10 minutes before making a final decision.
Packaging Issues
The squeeze tube can sometimes dispense too much product. Solution: Store the tube upright and squeeze very gently from the bottom to control the amount of product released.
Dryness
On very dry skin, the formula can sometimes emphasize texture. Solution: Make sure to properly hydrate the under-eye area with a good eye cream before application, or mix a drop of facial oil with the concealer.
Tips from Makeup Artists: Professional Advice for Perfect Application
Professional makeup artists who regularly use IT Cosmetics Bye Bye Under Eye Concealer have developed several techniques to get the most out of this powerful product:
- Color Correct First: For very dark circles, especially those with purple or blue undertones, apply a peach or orange color corrector before the concealer for the most natural-looking coverage.
- Layer Strategically: Rather than applying one thick layer, build up thin layers for a more skin-like finish that’s less likely to crease.
- Mix Shades: Many pros keep multiple shades on hand and mix them to create the perfect match for different areas of the face or to adjust for seasonal skin tone changes.
- Use as Foundation: For clients who need full coverage but don’t want the heaviness of full-face foundation, some makeup artists use Bye Bye Under Eye as a spot foundation, applying it only where coverage is needed.
- Brush Choice Matters: A small synthetic concealer brush with dense bristles works best for precise application, while a damp beauty sponge is ideal for final blending to achieve an airbrushed finish.
- Setting Technique: Rather than heavily powdering the entire under-eye area, use a small brush to apply setting powder only to areas prone to creasing, leaving the outer portions more luminous.
Who Should Use IT Cosmetics Bye Bye Under Eye Concealer?
While this concealer has widespread appeal, it’s particularly well-suited for certain individuals:
- Those with significant dark circles who haven’t found sufficient coverage from other products
- Makeup users with mature skin who need coverage that won’t settle into fine lines
- People with dry under-eye areas who find most concealers too drying or cakey
- Anyone looking for a multi-purpose product that can conceal various skin concerns
- Special occasion makeup where long-lasting, waterproof properties are essential
On the other hand, this concealer might not be ideal for:
- Those who prefer sheer, lightweight coverage
- People who want a quick, low-maintenance makeup routine (due to the blending required)
- Very oily skin types (though setting with powder can help)
- Those seeking a dewy or glossy finish (the original formula has a natural, satin finish)
The IT Cosmetics Philosophy: Understanding the Brand Behind the Product
IT Cosmetics (which stands for Innovative Technology) was founded by Jamie Kern Lima, a former news anchor who struggled with rosacea and sought to create products that could provide coverage without irritating sensitive skin. The brand is built around the philosophy of developing “problem-solving makeup” in collaboration with plastic surgeons and dermatologists.
This approach explains why Bye Bye Under Eye Concealer contains such a robust mix of skincare ingredients. The brand believes makeup should not just cover skin concerns but help address them over time. This philosophy resonates particularly well with consumers who are looking for multi-functional products that bridge the gap between makeup and skincare.
In 2016, IT Cosmetics was acquired by L’Oréal for $1.2 billion, one of the largest acquisitions in the beauty industry. While some loyal fans worried this might change the formulations they loved, the brand has largely maintained its focus on creating innovative, skin-friendly makeup products.

The waterproof, long-wearing formula delivers on its promises, providing reliable coverage for even the most challenging under-eye circles and skin concerns. While the thick consistency might require a learning curve for some users, the results are worth the effort for those seeking serious coverage that looks natural when properly applied.
At its price point, it represents good value considering how little product is needed per application and its multi-functional nature. The expanded shade range is also commendable, allowing more people to find their perfect match.
Is it perfect for everyone? No product is. But for those struggling with significant dark circles, hyperpigmentation, or other skin concerns that lighter-coverage products just can’t address, Bye Bye Under Eye Concealer offers a powerful solution that can dramatically improve confidence and simplify makeup routines.
Whether you’re new to the product or considering a repurchase, understanding how to properly apply and work with the unique formula is key to achieving the best results. With the right techniques, this little tube can indeed help you say “bye bye” to under-eye concerns and hello to a more refreshed, confident appearance.
