You Won't Believe How Much Celebrity Eyebrows Have Changed in the Past 20 Years

They say that change is the only constant in life, and we must agree—especially when it comes to our eyebrows.

Remember when tweezers were your BFF and Posh Spice was the epitome of #browgoals? Or have you blocked that from your memory entirely? In the past 20 years, eyebrows have gone from barely more than a skinny line to thick, full, and unapologetically bushy. Who hasn't looked back on her brows at one point in her life only to want to permanently hide under a pillow? (Cara Delevingne might be the only exception.)

So, for science—and honestly, a little comic relief—we felt it was time to review some of the most iconic eyebrow looks of a few of our favorite brow trendsetters of decades past. We dug up images of Pamela Anderson's drawn-on arches via the Baywatch era. And who can forget Drew Barrymore's pencil-thin brows? They're so iconic, we once penned a love letter to them. Plus, remember when Christina Aguilera took the skinny eyebrow look to the extreme in 2002? Ugh, it's all too good, you guys, so we'll stop reminiscing and let you get on with it. See all these looks and more in the video above.
