Beauty Bye Bye Under Eye Shades Compared: Find Your Match Today
We compared five Bye Bye Under Eye options: four full-size shades from 10.5 Light to 33.5 Tan Natural, plus the travel size in 13.0 Light Natural. Prices range from fourteen to twenty-nine dollars. All share the same full-coverage waterproof formula; the differences are shade, undertone, and size. Below is the breakdown of coverage, creasing, shade matching, and value to find your perfect match.
| Factor | IT Cosmetics Bye Bye Under Eye Concealer | IT Cosmetics Bye Bye Under Eye Concealer |
|---|---|---|
| Coverage Level | All five deliver identical full coverage, the formula does not vary by shade. One rice-grain dot covers dark circles completely. The coverage is buildable but rarely needs building. No shade offers more or less coverage than another. This is the most consistent aspect of the line. | |
| Shade Range Usefulness | The five options cover fair cool through tan neutral usefully. 10.5 Light serves the fairest cool tones. 13.0 Light Natural is the most universally flattering light shade. 14.0 Light Tan warms up light-medium skin. 20.0 Medium hits the popular middle. 33.5 Tan Natural extends into tan. The range could go deeper, but it covers the majority. | |
| Crease Resistance | Creasing depends on application, not shade. All five set equally well with proper powder setting. The travel size performs identically to full sizes. Users who apply thinly report minimal creasing across shades. Technique is the variable, and it is fully in your control. | |
| Undertone Accuracy | The numbered system describes undertones honestly. 10.5 runs genuinely cool, 14.0 runs warm, the .0 shades stay neutral. This accuracy helps buyers choose correctly. Few concealers label undertones this clearly. Trust the numbers when selecting. | |
| Travel vs Full Size Value | The full sizes offer far better value per ounce for daily users. The travel size costs more per use but lets you test shade and formula. Frequent travelers appreciate the compact tube. Buy travel to test, full size to commit. The math clearly favors full size long-term. | |
| Best for Beginners | The 13.0 Light Natural travel size is the best beginner entry: forgiving neutral shade, low price, and small commitment. The 20.0 Medium full size suits confident medium-skin buyers. Beginners should always start with the travel size to learn the less-is-more technique cheaply. | |
| Overall Winner | The 20.0 Medium full size wins overall as the most broadly useful shade with the best long-term value. The 13.0 Light Natural travel size is the runner-up and the smartest first purchase. Match your skin to the shade chart, start with travel, then commit to full size. | |
Our Verdict
The 20.0 Medium full size is the overall winner for its versatile neutral shade and excellent per-ounce value. The 13.0 Light Natural travel size is the smartest starting point for testing shade and learning the application technique. All five share the same excellent full-coverage formula, so the decision is purely about shade match and size. Take time with the shade numbers, apply less than you think you need, and this concealer will transform your under-eyes.
