Model Tyra Banks has posted an eye-opening "before" picture -- before all the makeup.

We've got one thing to say, girl: You better work!

Maybe she's born with it? More like: Maybe it's Maybelline -- or MAC.

Banks acknowledges the role of mother's little helpers.

This is the caption she wrote with the before picture:

"You know how people say  #nofilter  but you know there's a freakin' filter on their pic? Or maybe there's a smidge of retouching going on but they're lying and saying it's all raw & real? Well, this morn, I decided to give you a taste of the really real me. I wanted to smooth out my dark circles so badly!!! But I was like, "Naw, Ty. Show 'em the REAL you." So...here I am. Raw. And there YOU are...looking at me, studying this picture. Maybe you're thinking, "Whoa, she looks ROUGH." And if you are, great! You deserve to see the REAL me. The REALLY real me.  #RawAndReal."
