If anyone has mastered the art of aging gracefully, it's Sarah Michelle Gellar. The actress may no longer be in her 20s (she's 49, to be exact), but she still looks like herself - a.k.a. the same kickass queen we fell in love with in Buffy the Vampire Slayer, Cruel Intentions and the million other iconic credits on her IMDB. Her secret isn't finding the fountain of youth or going under the knife for some shape-shifting procedure. It's actually a $26 cream you can buy at the drugstore.
