Hailey Bieber and Khloé Kardashian Love This Fall-Appropriate Eyeliner (Hint: It's Iconic)

I associate each season with a certain beauty aesthetic. For winter, it's full-coverage foundations and bold lipstick. For spring, it's pink blush and pastel nail colors. Summer is all about effortless hairstyles and glowing makeup products. Finally, I associate fall with soft, sultry, and neutral makeup looks. Think shades of taupe, cognac, and espresso.

Apparently, Hailey Bieber and Khloé Kardashian agree because I just found out they love using the same brown eyeliner to create their fall makeup looks (well, the same product in slightly different shades). It's not just any old eyeliner, either. It's an iconic one that's been a staple for makeup artists for years. Can you guess which one it is? Hint: It's creamy, waterproof, and lasts up to 24 hours. Keep scrolling to see which eyeliner it is and shop the exact shades used by the celebs.

Hailey Bieber

Hailey Bieber recently posted a TikTok makeup tutorial in which she created one of her signature glowing makeup looks. To line and define her eyes, she used an iconic product: Urban Decay's 24/7 Glide-On Waterproof Eyeliner Pencil. Beloved by editors, makeup artists, and celebs alike, this eyeliner is creamy, highly pigmented, waterproof, and long-lasting—like lasts-for-up-to-24-hours long-lasting. As such, it can be used on both the eyelid and the waterline for budge-proof definition.

Bieber used the shade Whiskey, which is a rich, matte brown color. Unlike standard black eyeliner, which can look intense, edgy, and even severe, depending on how you wear it, brown eyeliner is soft and sultry. It defines and accentuates the eyes without looking as harsh.

Khloé Kardashian

Meanwhile, Khloé Kardashian prefers an even softer brown shade of Urban Decay's 24/7 Glide-On Waterproof Eyeliner Pencil. She recently shared a BTS look at her makeup session with celebrity makeup artist Ash K Holm on Instagram. The picture showed her "special liner," which has been used so much that it was sharpened down to a mere stub. The shimmery copper color is so flattering.

This makes me want to swap my black eyeliner for brown until further notice, so that's exactly what I'm going to do. In the meantime, I'm also going to shop for more sultry brown eye makeup products. See a few that made my wish list below.
