WHEN Catherine Zeta-Jones stepped out at the premiere of the new Dad’s Army film, her radiant complexion attracted as many admiring comments as her beautiful gown. The 46-year-old Hollywood star later revealed that the secret to her glowing skin is argan oil, a deeply moisturising beauty oil from Morocco. “I’m finding that from travelling and being in heated hotel rooms that my skin feels like a crisp. I’ve been using argan oil to saturate my skin at night so it has some nourishment as I sleep,” she says. There’s no doubt that beauty oils pack a powerful punch when it comes to treating dull winter skin. And experts agree that argan oil is one of the best. This nourishing skin treat contains twice as much vitamin E as olive oil, is rich in antioxidants and is a natural anti-inflammatory.
