Posing in her birthday suit, Trinny Woodall appears in remarkably good shape for her 46 years.
She is happy to admit, however, that there is a lot more to her than meets the eye.
The fashionista best known for her What Not To Wear programmes has given a frank interview in which she admits to using a variety of scary and expensive beauty treatments, including the wrinkle filler Botox, to stave off the ageing process.
Don't be shy, is Trinny's advice to women
'I think it's unnecessary to go all coy and French and pretend you're just amazingly beautiful naturally,' she says.
'I would advise women not to be shy about admitting they've had Botox - it just shows you want to look your best - and there's nothing wrong with that. I judge when I need a top-up of Botox by looking in the mirror to see if I can move more than half my forehead.'
The mother-of-one, who has spent time in rehab for alcoholism, confesses that she has been 'obsessed' about her skin ever since she was first blighted by severe acne at the age of 13.
'I will admit I am quite obsessive about the world of anti-ageing,' she says.
'But you know what? I love it. I can't deny that. We might not all have had the good fortune to be born with a perfect complexion, but we can make it happen, with a little help.

'Would I consider surgery? For me, it's about maintenance and prevention rather than going under the knife. It's a line I don't want to cross.'
Trinny tells how she first went to the London skin care specialist Dr Jean-Louis Sebagh to get rid of her acne scarring. He used a laser to even out the marks and she says she looked like 'a burns victim' for three months until her face healed.
In her 30s she started Botox three times a year, costing £400 a visit, as well as £250-a-time vitamin injections and £140 facial peels. She also started having the dark circles under her eyes 'filled in' seven years ago.
She tells Tatler magazine: 'For the past three years I have been enjoying the painful pleasures of Fraxel - from £800 - a laser that tightens and lifts the skin, especially around the jawline.'
She boasts: 'My pain threshold is quite high when it comes to vanity.'
Trinny, who in 2008 split from her husband, businessman Johnny Elichaoff, adds: 'I think Americans on the whole are a lot more into skin than we Brits. We're lazy and not so vain. In New York, it's all about looking smooth and youthful for the third or fourth husband.'

She admits she is more 'paranoid' about finding grey hair than wrinkles and her 'real obsession' is beauty products.
She also takes fish oil and massages her face daily.
'A few weeks ago someone I'd never met before came up to me and said, "You have amazing skin",' she adds.
'I immediately checked out the lighting and thought, "If only they could see me in daylight".'
