Why are men allowed to have wrinkles?

I noticed in my recent Marie Claire Magazine (November 2015 issue) that all male models in the ads have wrinkles, while the women are all photoshopped and have no wrinkles (even Julia Roberts or Naomi Watts who are 48 and 47 have no wrinkles!).  

I  wonder: why are men allowed to have wrinkles and women are not? Why is there so much pressure for women to be beautiful? A men looks strong and powerful and- well "manly" with wrinkles but a women is not allowed to show any age? Not fair!
