Hollywood beauty Halle Berry has slammed women who have plastic surgery.

The Catwoman star said going under the knife in an effort to look younger was "insane".

"I do think we've become obsessed with beauty and the fountain of youth and, frankly, personally I'm really saddened by the way women mutilate their faces today in search of that," she said.

"I see women in their thirties getting plastic surgery, pulling this up and tucking that back.

"It's like a slippery slope - once you start you pull one thing one way and then you think, 'Oh my God, I've got to do the other side'.

"There is this plastic, copycat look evolving and that's frightening to me.
"It's really insane and I feel sad that's what society is doing to women."

Berry, 37, was speaking at a press conference in London to promote new movie Catwoman.

The Oscar-winning actress recently told how being beautiful had done her no favours.

"Beauty? Let me tell you something - being thought of as 'a beautiful woman' has spared me nothing in life. No heartache, no trouble. Love has been difficult. Beauty is essentially meaningless and it is always transitory," she
said.

Berry attended the press conference at the Dorchester Hotel with co-star Sharon Stone.

Stone, 46, was more forgiving on the subject of cosmetic enhancement.

"I'm not big on plastic surgery but I don't fault it for someone who wants it," she said. "You have to do what makes you feel good, but it's not my thing."
