And the fresh-faced Red Riding Hood star says the comments were made when she was barely out of her teens.
Seyfried – who refuses to name the director of photography who she claims made the comment – makes the revelation in the latest issue of US Elle.
“I was like: ‘Damn you!’” she tells the magazine.
“But we’re in Hollywood. I’m on a huge screen. With these new digital cameras you can see the peach fuzz on my face.”
Despite refusing to have Botox, the Big Love star does admit to paying for her older sister Jenni’s recent nose job.
The actress – who shares a house with her sister in Los Angeles – says: “After she did it, I was like, ‘I could totally…’ It’s so accessible.”
When asked if her sister would be annoyed with her for discussing her plastic surgery so publicly, she says: “No way! She’s totally proud of it!”
