Amanda Seyfried, what's your beauty secret?

The actress shared the ultimate Flashback Friday photo when she posted her very first headshot on Instagram.

And we think she hasn't aged a bit!

Seyfried, 30, got her start starring in soap operas like As the World Turns and All My Children before she went on to play in Karen Smith in 2004's Mean Girls.

These days, she's the face of Givenchy fragrances and was the celebrity spokesperson for Movado and Clé de Peau Beauté.

Seyfried dished about her skincare regimen to Vogue, telling the publication that she likes to keep it simple.

"My skin has actually never been as clear as it is now. I wake up, and wash my face with the Cleansing Foam," she said in December 2014. "I maybe put on concealer depending what I'm doing, then I apply my UV Protection Cream and I walk out the door. I don't need to cover anything up."
