Nigella Lawson is almost as famous for her stunning good looks as for her cooking. 

But the superstar chef confesses, ‘I don’t have a beauty secret!’

However, she admits there is more to it than that. ‘The thing is, I drink more water than you can believe possible – three litres a day. And I never go in the sun, I’m very sunphobic.

‘Since I was 25, I wash my face everyday with a  muslin cloth to get all the dead bits off. I use Eve Lom cleanser (£55, John Lewis) and it gets my skin absolutely clean and leaves it so soft.’

As for beauty essentials, she keeps her kit small. ‘I travel a lot so I don’t carry many beauty products,’ she explains.

‘I have the cleanser, Elizabeth Arden Eight Hour Lip Protectant Stick (£20, Boots), Laura Mercier pressed powder (£31, John Lewis), and Estée Lauder eyeliner pencil and Advanced Night Repair Complex (£44, Boots), which is wonderful for burns I sometimes get in the kitchen.’
