Sarah Michelle Gellar says she has body dysmorphic disorder.

The 'Buffy The Vampire Slayer' actress admits having the psychological condition, which causes sufferers to worry about perceived defects in their appearance and can lead to anxiety and depression, and is uneasy looking at herself in the mirror.

She told Health magazine: "I'm a female! I totally have body dysmorphic disorder. I think most women do.

"A makeup artist friend once said, 'I don't think I've ever seen you look in a mirror.' I'm surrounded by them all the time - you sit in hair and makeup - so I guess I just have this mechanism where I tune it out.

"So every once in a while, I'll look and I'll be like, 'Wait, that's what I look like?'

Sarah – who is married to actor Freddie Prinze Jr. - added having her daughter, Charlotte, two, helped her with the way she perceives herself.

The 34-year-old star added: "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. It has to. Your priorities are different.

"I'm not as critical as I used to be about my body."
