IF you're wondering how Catherine Zeta-Jones manages to keep her skin so dewy at 46, she's more than happy to share her secret.
The Hollywood star has told how she uses argan oil to moisturise her complexion, saying she "saturates" her face with it to keep her looking youthful.
Although the product is becoming increasingly popular in the kitchen for its supposed health properties, Zeta Jones, like many women, prefers to make it part of her daily beauty regime.
During a webchat yesterday, the star said her hectic workload was taking its toll on her appearance and leaving her complexion as dry as a potato crisp.
She said: "I'm finding, just from travelling from New York and being in heated hotel rooms, my skin feels like a Walker's crisp at the moment, but I've been using some argan oil just to saturate my skin at night, so it has some nourishment as I sleep, to start the day a little bit more hydrated."
The Oscar-winner, who is in the midst of a the promotional tour for the new Dad's Army film in which she plays a glamorous journalist, added: "The real hydration comes from within. You can never drink too much water. No diet sodas!"
