Sarah Michelle Gellar isn't always happy with what she sees in the mirror.
The 34-year-old Ringer star (and mom to daughter Charlotte, 2, with husband of nine years Freddie Prinze, Jr., 35) tells the October issue of Health that she's not always confident in her own skin.
"I totally have body dysmorphic disorder. I think most women do," Gellar reveals. "I just have to remember that I'm human, and I'm a mom. Being a parent changes the vanity at least a little bit."
(Body dysmorphic disorder is a disease in which a person becomes obsessed with an imagined flaw in his or her appearance.)
Gellar adds that she would never use a photo of another actress' body for inspiration. "I would never do that to myself, especially because I'm aware of the airbrushing and trainers and food programs," she says. "You have to use yourself as inspiration."
"I think if I was going to put something up, I would put a picture of myself where I was proud of my body. But I would rather not look at a picture of myself on my fridge."
The actress cites Duchess Catherine and Pippa Middleton as examples of varying ideals of beauty and health.
"It seems like people are worried that Catherine's stressed. I feel like 10 years ago, it would have been like, 'Oh, she looks incredible,'" Gellar tells Health (on newsstands September 23). "Whereas you look at her sister, who has such a fabulously athletic body. . . I think there's this movement now, where more women, finally, want to look like that."
