I have a friend who does photo retouching for lots of the magazines that feature lovely celebs on the covers. He told me that ALL of the pics we see of the women we sometimes lust for on the magazine rack have been digitally retouched to erase wrinkles, smooth out complexions, etc.
Except when it came to Drew Barrymore. According to this source, it was obvious what to retouch with every other woman, but with her they couldn't find anything. He wasn't claiming that she's the hottest babe anywhere or anything, but she has damn nice skin, and it's real.
