The food writer and TV presenter, 59, explained in her The Sunday Times’ Style column today how, while she has tried “numberless creams, oils and unguents over the years”, it’s a bottle of prickly pear oil that stands out.
“It’s an unprepossessing little bottle, but what it contains is face-saving magic,” the cookery show host wrote.
“Put it on at night and you’ll wake up looking as if you’ve been to a spa by the sea, slept 10 hours a night and been off Twitter for a month.”
Nigella added: “It’s not just that it moisturises: it seems to heal my skin and make it so much more elastic.”
She explained that after realising the benefits it was having to her complexion, she decided to use it on her “reptilian hands” at night too – and it was able to reverse the effects of failing to regularly wear washing up gloves.
If there’s any excess, she rubs the ends of her hair with it – often negating the need for conditioner in the shower – and likewise dabs it on rough elbows and cuticles.
Nigella also revealed that to maintain her youthful looks she cleanses make-up off every night with a muslin cloth.
This has an exfoliating effect, she explains, which gets “rid of old, dead skin cells and keep my complexion bright”.
