Actress Jennifer Aniston has publicly expressed her fear of Botox, because she thinks that it makes people look emotionless.

The 40-year-old previously admitted that she had Botox, but she said that she didn’t like the results. She says that it leaves people expressionless, which can be detrimental to an actress.

“You see women and you know they are not young but you can’t tell how old they are,” said Aniston. “It makes them look harder. The warmth in their face goes away. It is not a good look.”

She credits her youthful appearance to a healthy diet.

“I’m a realist,” comments Aniston. “If I eat burgers and fries everyday I won’t get the parts I’m offered. I’d become a character actress, that might be fine one day but not right now.”

She continues: “I don’t think a lot about my physical appearance. It is what it is and I can’t control it… I just feel I am what I am.”
