Thandie Newton has a secret beauty weapon - turmeric.

The 39-year-old actress believes the spice is an excellent addition to a moisturiser to help match her skin-tone.

She told Britain's HELLO! magazine: "Olay does a great tinted moisturiser that I add a little turmeric to - making it more yellow depending on my skin tone and the season.

"That's a great trick for all women who find that foundations are too ashy or too Pink for their Skins. And it's anti-inflammatory. It's my secret weapon."

Despite her unusual tip, on the whole Thandie is not high maintenance when it comes to looking good.

She added: "Generally, I am low maintenance, but during the run of 'Death and the Maiden' I had to wear a lot of eye make-up, which meant using a great cleanser.

"I apply Neal's Yard Rose Beauty Balm, work it in, then remove it when a flannel rinsed in warm water. It dissolves everything. After that I just need a few dabs of Olay moisturiser."
