We can't beat the effects of age, unless we Benjamin-Button our way into youthfulness. While that is impossible until science finds a better age-defying answer, it appears that some celebrities have managed to look better now than when they were younger.

These celebrities' second chance at youth could be due to less-crazy hairstyles, the improvement of skincare and cosmetics, or a better-rounded health and fitness plan, or just really fantastic plastic surgeries. Whatever it is, they're looking stunning today.
