Cate Blanchett uses emu oil to keep her skin hydrated.

The 'Blue Jasmine' actress has revealed she applies the product - which is extracted from the fatty tissue on the bird's back - to nourish her skin and keep her complexion glowing.

The Melbourne-born star said of her beauty regime: ''I tend to use really basic creams, and I like to put an oil on, like an emu oil from Australia. It's from the emu and it's really nourishing. I prefer an oil to a cream.

''In indigenous Australian culture, that's the first oil they put on a baby because it's so hydrating. It's all pretty basic.''

The 45-year-old beauty also keeps her skin hydrated from the inside by drinking hot water with lemon and tries to keep her life as worry-free as possible to ensure her stress levels don't take their toll on her looks.

She told MailOnline: ''I drink hot water with lemon. Everyone says, 'Try this' or 'Try that', but they all come back to basic principles. They all come back to hydrating, drinking enough water and making sure you don't eat over-processed food.

''The other thing that's really bad for your gut and skin, and really bad for your mind, is stress levels. Anything you can do to reduce your stress levels - which is hard if you're under economic pressure or in relationship pressure - those things take a toll on you and your skin.

''But anything you could do to ease that part of your life will have an impact. How you feel affects how you look.''
