Women in their 20s usually don't worry too much about aging; a swipe of moisturizer and a healthy dose of SPF is usually all it takes to keep your skin looking supple in your "me" years.
But still, we've all heard those stories about girls who get plastic surgery at 24 or, like Kim Kardashian, Botox injections at 29. Apparently, some of us start fretting about our aging skin waaay before we need to.
Frankly, we think that's a load of nonsense, and we decided to check out some pics of celebrity women to see just how much they aged while going from 20 to 30 in the public eye. While celebs like Katie Holmes and Michelle Williams were just cutting their acting chops on "Dawson's Creek" at age 20, others like Gwyneth Paltrow and Drew Barrymore were already starring in movies, and Britney Spears and Jessica Simpson were bona fide pop stars -- and they looked even more gorgeous ten years later.
All in all, we think all of these stars aged beautifully in their 20s. Some of them look virtually the same! Here are some photos of Hollywood's leading ladies at age 20 and 30 (or as close to those ages as we could find) -- check out all that '90s hair.
