Charlize Theron thinks women only "come into their prime" in their 40s.
The 39-year-old 'Prometheus' star, who is dating Sean Penn, 54, says 20-year-olds "have no f**king concept" about life and believes the beauty industry should focus on older women.
She told Women's Wear Daily (WWD) magazine: "It's ironic that we've built the beauty world around 20-year-olds, when they have no f***ing concept about wisdom, what life is about, having a few relationships below [their] belt and feeling hardships, to grow into [their] skin and feel confident within [themselves] and to feel the value of who [they] are, not because of a man or because of something like that.
"And I think that's such a beautiful thing. And that's why I think people say women come into their prime in their forties."
The South-African star, who has a two-year-old son, Jackson, also admits she feels a lot more sensual and secure about her looks as she gets older.
She said: "It's like we wilt for some reason. And men are like fine wines - the older they get, the better they get. It's such a misconception, and it's such a lost opportunity because that's when I think women are really in the true moment of their sensuality."
The Dior ambassador added: "I think that women find their strength and power in their sexuality, in their sensuality within, [through] getting older and being secure within that."
