According to 56-year-old model Yasmina Rossi, the secret of looking good over 50 is cheaper – and easier – than any of us realized.

All that’s needed, says the Miami-based M&S campaign star, is a healthy diet, minimal exercise and plenty of rapeseed oil for your hair and skin.

“There is no big secret,” Yasmina Rossi told the Sunday Times’ Style magazine.

“All I have ever done is to eat organic food – long before it became trendy.

“I take oil and use it on my skin: I put rapeseed oil on my hair. I scrub my skin once a week with olive oil and fine sugar. I eat an avocado a day and good organic meat and fish.”

The grey-haired French-born model is currently starring in the M&S Christmas ad campaign and has previously worked for YSL, Hermes, Jil Sander and Macy’s.

Unusually, Yasmina Rossi began modelling in her late twenties – the age at which most models retire – after 10 years as a stay-at-home mother.

A mother of two with two grandchildren, Yasmina Rossi’s career took off at the age of 45, when she relocated to New York.

There, Yasmina Rossi starred in ad campaigns for Macy’s, AT&T and Mastercard, before landing the M&S job back in Europe.

Despite working in a looks and youth obsessed industry, Yasimina Rossi says she’s happier with her looks now than she was in her twenties.

“I like the way I look now more than how I looked 20 years ago,” she revealed.

“My body is nicer and I feel happier than when I was 20.”

Holding back the years, Yasmina Rossi continued, is easy when you eat a good diet and don’t overdo the exercise.

“This is very important. And don’t take medicine if possible. Go with nature instead of fighting it – this is the rule for everything.”
