First Impressions & Packaging
The L'Oreal Infallible Pro Last Waterproof 24-hour wear eyeliner pencil in Cobalt arrived in its signature sleek packaging. The color of the pencil is clearly visible through the outer casing, eliminating the need to remove the cap to check the shade. This is a convenient design feature, especially when you're in a rush.

The packaging also displays the product's benefits and instructions on how to use it, including the ability to apply it to the waterline. A quick glance at the back revealed the ingredient list for those who may have sensitivities or allergies.

Application and Texture
The eyeliner pencil itself is incredibly creamy and glides on effortlessly. Applying it with a light hand results in a precise and beautiful line. The intense pigment delivers a rich cobalt blue in a single swipe.

The creamy texture ensures a smooth application without any tugging or pulling on the delicate eyelid skin. This makes it ideal for both beginners and experienced makeup users alike.

Longevity and Waterproof Test
One of the key selling points of this eyeliner is its impressive 24-hour wear claim. I put this to the test by wearing it overnight, and I was pleasantly surprised to find that it was still perfectly intact when I woke up.

To further test the waterproof claim, I used an alcohol-based makeup remover wipe. As expected, removing the eyeliner was challenging, demonstrating the product’s impressive staying power even with a harsh remover.

Final Verdict
Overall, the L'Oreal Infallible Pro Last Waterproof Eyeliner Pencil in Cobalt is a high-performing product that delivers on its promises of long-lasting wear and intense color. The creamy texture makes application a breeze, and the waterproof formula ensures smudge-proof wear throughout the day (and night!).

While the impressive staying power requires a strong remover to take off, it's a small price to pay for such a long-lasting and vibrant eyeliner. For those seeking a reliable and beautiful cobalt blue eyeliner, this is a definite must-try.
