The Aussie actress, model and singer opened up to Britain's The Daily Mail about her skin, hair and makeup routine, and revealed a little insider trick that an Australian dermatologist taught her way back when.
Her biggest splurge: Crème De La Mer ($250)
Her naughty secret: Cortisone cream for clearing up pimples. Tut tut Holly.
Her favourite mascara: L'Oréal Extra-Volume Collagene Mascara ($26.95)
Her haircare brand of choice: Pureology. Me too Holz.
Her exercise routine: Hiking in the hills of LA. She used to be a martial arts girl but gave it up to help quieten her mind.
Best beauty tip ever: Porridge as a face mask to help calm the skin. "I heat porridge oats with water, let it cool for a couple of minutes, pour it into a tea towel and place it over my face."
Stockists: L'Oréal (1300 659 259), La Mer (1800 661 392), Pureology (1300 386 421).
