She might be the face of Elizabeth Arden cosmetics, but Catherine Zeta- Jones is happy to use her own homegrown beauty secrets. Such as rubbing honey and salt on her skin to beat wrinkles, washing her hair in beer and brushing her teeth with a strawberry.

In an interview, the 39-year-old actress admits that the answer to preserving her youthful appearance lies as much in her kitchen as her make-up bag. ‘I rub a mixture of honey and salt all over my body to moisturise and exfoliate,’ she says.

‘You wash it off and your skin is gorgeous. Also, I love to eat an apple after a meal, just to cleanse my teeth – they always look polished afterwards.’ If there aren’t any apples in the fruit bowl, a strawberry will suffice. ‘The juice or pulp of strawberries contains malic acid which serves as an astringent and can lighten surface stains,’ she explains. ‘ Pineapples work the same way.’ The Swansea-born mother of two, who now lives in Bermuda with her actor husband Michael Douglas, became the global face of Elizabeth Arden in 2002 after signing a £5million contract.
